A Power Operated Chaff Cutter is an agricultural machine used for cutting and processing fodder such as straw, hay and other crop residues into smaller pieces suitable for livestock feeding. These machines may be powered by an electric motor, diesel engine, tractor PTO or another suitable rotary power source.<\/p>\n

Because a power-operated chaff cutter contains rotating shafts, blades, flywheels, feeding mechanisms, belts, pulleys and other moving parts, proper construction and operator protection are important. BIS certification for this product provides a structured conformity-assessment framework covering materials, construction, safety, testing and factory quality controls.<\/p>\n

Manufacturers searching for BIS Certification for Power Operated Chaff Cutter under IS 15542:2005<\/strong> should note an important regulatory development. BIS has revised the applicable requirements into IS 11459:2024 \u2014 Power Operated Chaff Cutter \u2013 Specification and Test Code<\/strong>. The revised standard merged the earlier IS 11459:1985<\/strong>, IS 15542:2005<\/strong> and IS 7897:1975<\/strong> requirements. BIS specified 28 November 2024<\/strong> as the implementation date after which the old standards were to be withdrawn for licensing purposes.<\/p>\n

Therefore, this article explains the historical IS 15542:2005 reference while also giving manufacturers the current BIS certification position under IS 11459:2024<\/strong>.<\/p>\n

\n
\n<\/div>\n
Important BIS Update: IS 15542:2005 Replaced by IS 11459:2024<\/h1>\n
The earlier standard:<\/p>\n
IS 15542:2005 \u2014 Power Operated Chaff Cutter \u2013 Safety Requirements<\/strong><\/p>\n
has been superseded in the revised certification framework.<\/p>\n
BIS issued implementation guidelines stating that:<\/p>\n
IS 11459:1985 + IS 15542:2005 + IS 7897:1975 \u2192 IS 11459:2024<\/strong><\/p>\n
The revised standard is titled:<\/p>\n
IS 11459:2024 \u2014 Power Operated Chaff Cutter \u2013 Specification and Test Code<\/strong><\/p>\n
BIS stated that the revised standard incorporates:<\/p>\n
\n
Test methods previously contained in IS 7897:1975<\/li>\n
Blade specifications previously covered by IS 1511:1979<\/li>\n
Safety requirements previously covered by IS 15542:2005<\/li>\n
Updated raw-material requirements<\/li>\n
Additional component requirements, including pedestal bearing, discharge box and flywheel cover<\/li>\n<\/ul>\n
The old-standard implementation ended on 28 November 2024<\/strong>, and BIS stated that licences were not to remain under the old standards after that date.<\/p>\n

What Is BIS Certification for Power Operated Chaff Cutter?<\/h1>\n
BIS Certification is a conformity-assessment process through which a manufacturer demonstrates that its product complies with the applicable Indian Standard.<\/p>\n
For Power Operated Chaff Cutters, the current certification framework is based on IS 11459:2024<\/strong>.<\/p>\n
The BIS Product Manual states that this certification operates under Scheme-I of the BIS Conformity Assessment Regulations, 2018<\/strong>. The manufacturer receives a licence to use the BIS Standard Mark<\/strong> on conforming production covered by the licence.<\/p>\n
For manufacturers who previously referred to IS 15542:2005<\/strong>, the current applicable reference should therefore be updated to IS 11459:2024<\/strong>.<\/p>\n
\n
\n<\/div>\n
What Does IS 11459:2024 Cover?<\/h1>\n
IS 11459:2024 specifies requirements for Power Operated Chaff Cutters<\/strong> and provides both product specifications and test methods.<\/p>\n

BIS Sample Requirements for Power Operated Chaff Cutter<\/h1>\n
Under the current IS 11459:2024 Product Manual<\/strong>, the sample quantity specified for laboratory testing during Grant of Licence, Change in Scope of Licence and Factory Surveillance is:<\/p>\n
2 Nos.<\/strong><\/p>\n
However, an important feature of this certification is that the licence is operated on a Factory Testing basis<\/strong>. The Product Manual states that complete testing of a sample is carried out in the factory and that approximately 2 days are required for complete testing and inspection<\/strong>.<\/p>\n
This is different from a certification system where the complete product-testing programme is performed only in an external laboratory.<\/p>\n
The exact sample arrangements should nevertheless be coordinated with the BIS office and applicable testing facility for the particular application.<\/p>\n
\n
\n<\/div>\n
Raw Material Requirements<\/h1>\n
Raw-material conformity is an important part of the certification process.<\/p>\n
The current Product Manual requires materials used for construction of the various chaff-cutter components to comply with Clause 5 of IS 11459:2024<\/strong>.<\/p>\n
The blade must conform to Clause 6<\/strong>.<\/p>\n
Conformity may be established through:<\/p>\n
\n
Supplier test certificates<\/li>\n
Test reports from BIS-recognized laboratories<\/li>\n
Test reports from empanelled laboratories<\/li>\n
Reports from NABL-accredited laboratories complying with IS\/ISO\/IEC 17025<\/li>\n
In-house testing<\/li>\n
A suitable combination of these methods<\/li>\n<\/ul>\n
as applicable.<\/p>\n
\n
\n<\/div>\n
Blade Requirements<\/h1>\n
The blade is a critical safety and performance component of a Power Operated Chaff Cutter.<\/p>\n
The revised standard incorporated the blade specifications that were previously covered by IS 1511:1979<\/strong>.<\/p>\n
The BIS technical description states that the blade hardness requirement is:<\/p>\n
40 HRC to 45 HRC<\/strong><\/p>\n
This requirement is intended to support effective cutting performance and durability.<\/p>\n
Manufacturers should maintain suitable records and controls demonstrating conformity of blade material and hardness.<\/p>\n
\n
\n<\/div>\n
Construction Requirements for Power Operated Chaff Cutter<\/h1>\n
The revised standard includes detailed construction requirements.<\/p>\n
Important components and safety-related areas include:<\/p>\n
\n
Cutting mechanism<\/li>\n
Feeding mechanism<\/li>\n
Flywheel<\/li>\n
Cutter head<\/li>\n

Transmission system<\/li>\n
Blowing unit<\/li>\n
Discharge box<\/li>\n
Flywheel cover<\/li>\n
Bearings<\/li>\n
Power-transmission components<\/li>\n<\/ul>\n
BIS specifically noted that the revised standard added pedestal bearing, discharge box and flywheel cover<\/strong> to the component list, while bush bearing was removed from the listed components.<\/p>\n
\n
\n<\/div>\n
Feeding Chute and Conveyor Safety<\/h1>\n
The feeding area is particularly important because the operator works near the material-feeding system and cutting mechanism.<\/p>\n
The current BIS technical description specifies minimum dimensions including:<\/p>\n
Minimum chute length: 900 mm<\/strong><\/p>\n
Minimum conveyor length: 1200 mm<\/strong><\/p>\n
The standard also requires a minimum 450 mm coverage of the chute or conveyor on the feed-roller side<\/strong> to protect the operator from injury.<\/p>\n
Manufacturers should ensure that the actual production design complies with these requirements and that the dimensions remain consistent with the certified model.<\/p>\n
\n
\n<\/div>\n
Safety Guards<\/h1>\n
Power-operated chaff cutters contain exposed moving and rotating parts that can create significant hazards.<\/p>\n
The revised BIS standard emphasizes protection of operators through suitable guards.<\/p>\n
Safety-related components may include:<\/p>\n
\n
Front safety guard<\/li>\n
Blade cover<\/li>\n
Flywheel cover<\/li>\n
Feeding chute cover<\/li>\n
Guards around moving parts<\/li>\n
Warning arrangements<\/li>\n
Protective arrangements around transmission components<\/li>\n<\/ul>\n
The earlier IS 15542:2005 Product Manual also specifically identified front safety guard, feeding chute cover, warning roller, blade cover and other safety components as items requiring inspection on each chaff cutter.<\/p>\n
\n
\n<\/div>\n
Power Consumption and No-Load Testing<\/h1>\n
The current Product Manual identifies power consumption<\/strong> as a type-test parameter.<\/p>\n

Visual observations<\/li>\n
Blowing efficiency<\/li>\n<\/ul>\n
The indicative equipment includes suitable fodder, tachometer, weighing balance, energy meter, measuring tape and a device for measuring the circumferential speed of the blower tip.<\/p>\n
\n
\n<\/div>\n
Long-Run Testing<\/h1>\n
The revised product manual also specifies a long-run test<\/strong>.<\/p>\n
The test uses appropriate equipment and fodder to evaluate the chaff cutter under extended operating conditions.<\/p>\n
The long-run evaluation is part of the type-testing programme for each model and is to be repeated when there is a relevant change in design or materials.<\/p>\n
\n
\n<\/div>\n
Type Tests Under IS 11459:2024<\/h1>\n
The current BIS Product Manual identifies the following important type-testing areas.<\/p>\n

The manufacturer must apply the Quality Assurance Plan and maintain appropriate records for production covered by the certification.<\/p>\n
\n
\n<\/div>\n
Quality Assurance Plan<\/h1>\n
The manufacturer is expected to establish a Quality Assurance Plan<\/strong> covering regular testing and in-process controls.<\/p>\n
The plan should define:<\/p>\n
\n
Control unit<\/li>\n
Frequency of testing<\/li>\n
Number of samples<\/li>\n
Applicable tests<\/li>\n
In-process controls<\/li>\n
Record-keeping arrangements<\/li>\n<\/ul>\n
The Quality Assurance Plan is to be submitted to the relevant BIS Branch Office for information, and the manufacturer must implement the plan and maintain test records.<\/p>\n
\n
\n<\/div>\n
In-House Testing Facility<\/h1>\n
The BIS Product Manual expects manufacturers to have an appropriately equipped and staffed in-house laboratory for routine requirements where necessary.<\/p>\n
For routine tests identified with an R<\/strong> classification, in-house testing facilities are generally required for large-scale manufacturers.<\/p>\n
For MSME manufacturers, the requirement to maintain a dedicated in-house laboratory for routine tests is optional. MSMEs may use:<\/p>\n
\n
Common cluster-based testing facilities<\/li>\n
Shared testing facilities<\/li>\n
BIS-recognized or empanelled laboratories<\/li>\n
NABL-accredited laboratories complying with IS\/ISO\/IEC 17025<\/li>\n<\/ul>\n
subject to the applicable provisions.<\/p>\n
\n
\n<\/div>\n

\n
\n<\/div>\n
Product Marking and ISI Mark Requirements<\/h1>\n
After BIS certification, conforming Power Operated Chaff Cutters covered by the licence must bear the BIS Standard Mark<\/strong> in accordance with the licence.<\/p>\n
The current Product Manual states that the Standard Mark must be incorporated legibly and indelibly on each chaff cutter and on the packaging<\/strong>, provided that the marked product conforms to all requirements.<\/p>\n
An additional marking requirement specified by BIS is:<\/p>\n
\u201cFor BIS certification details please visit <\/strong>www.bis.gov.in\u201d<\/strong><\/a><\/p>\n
This additional wording is to appear on each chaff cutter and\/or its packaging as specified in the Product Manual.<\/p>\n
\n
\n<\/div>\n
Operator Manual Requirement<\/h1>\n
Each certified Power Operated Chaff Cutter must be supplied with an operator’s manual<\/strong>.<\/p>\n
The current Product Manual states that the manual may be in:<\/p>\n
\n

\n
\n<\/div>\n
Model Details Required Under IS 11459:2024<\/h1>\n
A manufacturer seeking certification should prepare a complete technical datasheet for each proposed model.<\/p>\n
BIS specifically asks for details concerning:<\/p>\n
\n
Power unit<\/li>\n
Main drive<\/li>\n
Cutter head<\/li>\n
Feeding mechanism<\/li>\n
Blowing unit<\/li>\n
Transmission system<\/li>\n
Overall dimensions<\/li>\n

The Product Manual also states that samples of each model are to be tested to cover those models in the licence scope and that the licence scope may be restricted according to the manufacturing and testing facilities available.<\/p>\n
\n
\n<\/div>\n
Can Multiple Chaff Cutter Models Be Covered Under One BIS Licence?<\/h1>\n
The current grouping guidance requires the manufacturer to declare the technical details of each model number<\/strong> proposed for inclusion.<\/p>\n
The manufacturer should not assume that models with different mechanical or operational characteristics can automatically be treated as identical.<\/p>\n
Model differences may include:<\/p>\n
\n
Power<\/li>\n
Prime mover<\/li>\n
Cutter type<\/li>\n
Number of blades<\/li>\n
Feeding arrangement<\/li>\n
Conveyor dimensions<\/li>\n
Feed-roll arrangement<\/li>\n
Blower configuration<\/li>\n
Transmission system<\/li>\n
Dimensions<\/li>\n

The final licence scope is determined based on the applicable grouping guidelines, manufacturing facilities and testing facilities.<\/p>\n
\n
\n<\/div>\n
BIS Marking Fee for Power Operated Chaff Cutter<\/h1>\n
BIS’s current marking-fee schedule lists IS 11459<\/strong> under:<\/p>\n
Power-Operated Chaff Cutter \u2013 Specification and Test Code (First Revision)<\/strong><\/p>\n
The published marking-fee figures are:<\/p>\n
Large Scale Manufacturer:<\/strong> \u20b971,000<\/p>\n
Medium Scale Manufacturer:<\/strong> \u20b957,000<\/p>\n
Small Scale Manufacturer:<\/strong> \u20b935,500<\/p>\n
Micro Scale Manufacturer:<\/strong> \u20b914,200<\/p>\n
The unit for the marking fee is 1 machine<\/strong>. BIS’s published schedule also gives the applicable unit-rate slab information.<\/p>\n
These are BIS marking-fee figures and should not be treated as the complete project cost. Other applicable certification expenses, inspection-related costs, testing expenses and professional consultancy charges may be separate.<\/p>\n
\n
\n<\/div>\n
What Is the Total Cost of BIS Certification?<\/h1>\n
The overall cost of BIS certification can depend on:<\/p>\n
\n
Manufacturer scale<\/li>\n
BIS marking fee<\/li>\n
Applicable application\/certification charges<\/li>\n
Factory inspection<\/li>\n
Testing arrangements<\/li>\n
Additional testing requirements<\/li>\n
Calibration<\/li>\n
Documentation<\/li>\n
Product modifications<\/li>\n
Consultancy<\/li>\n
Travel\/logistics where applicable<\/li>\n<\/ul>\n
Because the certification is operated on a Factory Testing basis, the cost structure should be assessed differently from products that depend entirely on outside laboratory testing.<\/p>\n
A current project quotation should therefore be prepared after reviewing the manufacturer’s factory, product models and existing testing facilities.<\/p>\n
\n
\n<\/div>\n
How Long Does BIS Certification Take?<\/h1>\n
The exact timeline depends on:<\/p>\n
\n
Factory readiness<\/li>\n
Documentation<\/li>\n
Product conformity<\/li>\n
Testing facilities<\/li>\n
Calibration status<\/li>\n
BIS inspection scheduling<\/li>\n
Query resolution<\/li>\n
Corrective actions, if any<\/li>\n<\/ul>\n
The current Product Manual states that 2 days are required for complete testing and inspection<\/strong> during the factory-based certification activity, but this refers to the inspection\/testing activity itself and not the entire application-to-licence timeline.<\/p>\n
The complete certification process may take longer depending on the application and BIS inspection schedule.<\/p>\n
\n
\n<\/div>\n
Common Reasons for Delay in Chaff Cutter BIS Certification<\/h1>\n
Manufacturers may face delays because of:<\/p>\n
\n
Using the obsolete IS 15542:2005 reference for a new application<\/li>\n

BIS Certification for Electric Motor Operated Chaff Cutters<\/h1>\n
An electrically powered chaff cutter is covered within the Power Operated Chaff Cutter product framework when it falls within the scope of the applicable standard.<\/p>\n
For such machines, the manufacturer should pay particular attention to:<\/p>\n
\n
Electric motor<\/li>\n
Power consumption<\/li>\n
Drive arrangement<\/li>\n
Rotating components<\/li>\n
Guards<\/li>\n
Electrical safety<\/li>\n
Mechanical transmission<\/li>\n
Factory testing<\/li>\n<\/ul>\n
IS 11459:2024 covers chaff cutters operated by electric motors as well as other permissible sources of rotary power.<\/p>\n
\n
\n<\/div>\n
BIS Certification for Diesel and Tractor-PTO Chaff Cutters<\/h1>\n
The revised standard also recognizes chaff cutters powered by diesel engines, tractor PTO systems or another suitable rotary power source.<\/p>\n
The certification scope must correspond to the actual power unit and transmission system of the machine.<\/p>\n
The manufacturer should declare the applicable power-unit and drive details for each model.<\/p>\n
\n
\n<\/div>\n
Safety Importance of BIS Certification<\/h1>\n
Power-operated agricultural machines can present hazards from:<\/p>\n
\n
Rotating blades<\/li>\n
Flywheels<\/li>\n
Feed rollers<\/li>\n
Belts<\/li>\n
Pulleys<\/li>\n
Shafts<\/li>\n
Blowers<\/li>\n
Moving transmission components<\/li>\n<\/ul>\n
The revised standard consolidates the earlier safety requirements and test methods into a single specification and test code.<\/p>\n
BIS has specifically explained that the earlier safety requirements under IS 15542:2005 were incorporated into Clause 15 of IS 11459:2024.<\/p>\n
\n
\n<\/div>\n
Transition from IS 15542:2005 to IS 11459:2024<\/h1>\n
Manufacturers who previously held certification under IS 15542:2005<\/strong> should understand the transition.<\/p>\n
BIS required existing licensees under both IS 11459:1985 and IS 15542:2005 to implement IS 11459:2024 by 28 November 2024<\/strong>. BIS also required evidence of conformity for additional or modified requirements and revised testing-equipment information.<\/p>\n
The revised standard therefore represents more than a simple renumbering.<\/p>\n
It combines:<\/p>\n
Specifications + Test Methods + Blade Requirements + Safety Requirements<\/strong><\/p>\n
within the revised IS 11459:2024 framework.<\/p>\n
\n
\n<\/div>\n
Major Changes Introduced by IS 11459:2024<\/h1>\n
According to the BIS implementation guideline, the important changes include:<\/p>\n
Test Methods Added<\/h3>\n
Test methods previously published in IS 7897:1975 have been incorporated.<\/p>\n
Blade Requirements Added<\/h3>\n
Blade specifications previously covered by IS 1511:1979 have been incorporated.<\/p>\n
Safety Requirements Integrated<\/h3>\n
Safety requirements previously covered by IS 15542:2005 have been incorporated.<\/p>\n
Raw Materials Updated<\/h3>\n
Raw-material specifications for different components have been incorporated or updated.<\/p>\n
Component List Changed<\/h3>\n
Pedestal bearing, discharge box and flywheel cover were added, while bush bearing was removed from the listed components.<\/p>\n
\n
\n<\/div>\n
ISI Mark on Power Operated Chaff Cutter<\/h1>\n
After receiving the BIS licence, only production covered by the approved scope and complying with the relevant Indian Standard should bear the Standard Mark.<\/p>\n
The current Product Manual requires the Standard Mark to be applied legibly and indelibly on:<\/p>\n
Each chaff cutter<\/strong><\/p>\n
and<\/p>\n
The packaging<\/strong><\/p>\n
subject to the applicable requirements.<\/p>\n
The product should also carry the additional BIS information prescribed in the Product Manual.<\/p>\n
\n
\n<\/div>\n
Role of Quality Control in Maintaining BIS Licence<\/h1>\n
Obtaining the BIS licence is only the beginning of ongoing compliance.<\/p>\n
Manufacturers must continue to:<\/p>\n
\n
Control raw materials<\/li>\n
Maintain production controls<\/li>\n
Perform routine tests<\/li>\n
Maintain test records<\/li>\n
Calibrate equipment<\/li>\n
Maintain safety features<\/li>\n
Control design changes<\/li>\n
Maintain marking requirements<\/li>\n
Keep the operator manual compliant<\/li>\n
Cooperate with surveillance inspections<\/li>\n<\/ul>\n
The BIS Product Manual states that all production covered by the quality plan must be subject to the applicable inspection and testing controls and that test records must be maintained.<\/p>\n
\n
\n<\/div>\n
Change in Design or Material<\/h1>\n
Design changes should not be introduced without reviewing their BIS impact.<\/p>\n
The current Product Manual states that type testing is conducted initially for each model and thereafter whenever there is a change in design or materials<\/strong>.<\/p>\n
Therefore, changes to components such as:<\/p>\n
\n
Blade<\/li>\n
Cutter head<\/li>\n
Feed mechanism<\/li>\n
Conveyor<\/li>\n
Blower<\/li>\n
Drive system<\/li>\n
Housing\/guards<\/li>\n
Materials<\/li>\n
Power unit<\/li>\n<\/ul>\n
may require technical reassessment before being incorporated into certified production.<\/p>\n
