BIS Certification for Asbestos Cement Pressure Pipes (Light Duty) | IS 9627:1980 – Qualitance India
BIS Certification for Asbestos Cement Pressure Pipes (Light Duty) – IS 9627:1980
Manufacturers and businesses dealing with asbestos cement pressure pipes should verify the applicable Bureau of Indian Standards (BIS) requirements before manufacturing, importing, supplying or marketing these products in India.
IS 9627:1980 is the Indian Standard titled
Specification for Asbestos Cement Pressure Pipes (Light Duty). BIS lists this product standard under its Scheme-I (ISI Mark Scheme) category for asbestos or fibre cement-based products. <Cite refs={["turn266335search0","turn266335search12"]}/>
Qualitance India provides consultancy support for BIS product certification, technical documentation, testing coordination and application preparation. This article explains the product scope, important testing requirements, certification process and information manufacturers should prepare before applying.
1. What Is IS 9627:1980?
IS 9627:1980 specifies requirements for the manufacture, classification, dimensions, tests and acceptance criteria for light-duty asbestos cement pressure pipes. The standard covers
Class 5 and Class 10 pipes. <Cite refs={["turn266335search12"]}/>
The standard addresses product characteristics that affect conformity and performance, including pressure-related strength, physical properties, dimensions and workmanship.
Manufacturers should obtain and review the applicable official edition, amendments and certification requirements before finalising product specifications or beginning the BIS application process.
2. Scope of the Standard
IS 9627:1980 is specifically for light-duty asbestos cement pressure pipes. The relevant product classification, nominal diameter, pipe class and intended application must be assessed against the standard and the manufacturer's actual product range.
The standard's testing and inspection scheme identifies requirements relating to:
- Material and composition
- Dimensions and tolerances
- Finish and straightness
- Hydraulic pressure-tightness
- Hydraulic bursting stress
- Transverse crushing stress, where applicable
- Longitudinal bending stress, where applicable
- Joints and associated requirements
The official BIS Scheme of Testing and Inspection specifies different checks depending on pipe diameter and production control unit. <Cite refs={["turn847121view2"]}/>
Important: IS 9627:1980 should not be confused with IS 1592:2003, which covers asbestos cement pressure pipes and joints under a separate standard. BIS lists both standards separately. The correct standard must be selected based on the product's construction, classification and intended scope. <Cite refs={["turn266335search0","turn266335search3"]}/>
3. Is BIS Certification Mandatory for IS 9627:1980?
BIS lists IS 9627:1980 in its Scheme-I (ISI Mark Scheme) category for asbestos or fibre cement-based products. The category is associated with the
Asbestos or Fibre Cement Based Products (Quality Control) Order, 2024. <Cite refs={["turn266335search0"]}/>
Manufacturers and importers should therefore verify the current Quality Control Order (QCO), subsequent amendments, and any applicable exemptions or restrictions before placing products on the Indian market.
The official BIS listing also refers to exemption orders dated 13 February 2026 concerning imports and purchases for the relevant product category. These orders may have a defined scope, so they should not be interpreted as a blanket exemption for every manufacturer or product. <Cite refs={["turn266335search0"]}/>
Before making a compliance decision, confirm:
- Whether the specific product is covered by the current QCO.
- Whether any exemption applies to the manufacturer, importer, purchaser or intended use.
- Whether the product must bear the BIS Standard Mark for the proposed transaction.
- Which current BIS requirements and amendments apply.
4. Important Quality and Testing Requirements
The BIS Scheme of Testing and Inspection (STI), document reference
STI/9627/1, describes factory-level controls for certification to IS 9627:1980. It calls for an appropriately equipped and staffed laboratory, test and calibration records, quality control, and inspection of production. <Cite refs={["turn847121view2"]}/>
4.1 Material and composition
The manufacturer should maintain relevant incoming-material records and carry out the checks required by the applicable standard and STI. The precise testing arrangements depend on the applicable requirements and accepted evidence for the materials used.
4.2 Dimensional inspection
Dimensional controls include checks on relevant pipe dimensions and tolerances, including nominal diameter, thickness, nominal length, internal diameter regularity and straightness as specified by the standard and STI.
4.3 Hydraulic pressure-tightness test
The STI requires
every pipe in a production control unit to undergo the works hydraulic pressure-tightness test. Pipes failing the test cannot be considered for marking under the scheme. <Cite refs={["turn847121view2"]}/>
4.4 Strength testing
The STI identifies hydraulic bursting stress, transverse crushing stress and longitudinal bending stress as relevant tests. The applicability of particular tests depends on the pipe requirements, including diameter where specified. <Cite refs={["turn847121view2"]}/>
4.5 Factory production control
The STI defines a control unit as
200 pipes of the same class and size, or part thereof, manufactured under similar conditions on the same day. It specifies sampling and inspection frequencies for dimensional and strength checks, along with provisions for handling failures. <Cite refs={["turn847121view2"]}/>
The current BIS requirements should be checked before relying on this STI for an application, particularly if the certification scheme or governing documents have been revised.
5. Factory and Laboratory Requirements
The BIS testing and inspection scheme states that the manufacturer should maintain a laboratory that is suitably equipped and staffed to perform the tests required by the specification. Test records, inspection records and calibration records must be maintained and made available to BIS when required. <Cite refs={["turn847121view2"]}/>
During preparation for certification, the manufacturer should assess:
- Availability of suitable testing equipment and measuring instruments.
- Calibration and maintenance arrangements.
- Trained personnel responsible for testing and inspection.
- Documented production and quality-control procedures.
- Records for raw materials, production, testing and rejected products.
- Facilities for conducting the required hydraulic and physical tests.
The exact equipment list, testing arrangements and any permitted external-laboratory arrangements must be confirmed against the current applicable BIS documents. Do not assume that every test can be outsourced or that a general-purpose laboratory will meet the requirements.
6. Marking Requirements
The BIS STI states that each pipe bearing the Standard Mark must conform to the applicable specification. It also identifies the following product marking information:
- Manufacturer's name or trade mark, if any.
- Date of manufacture.
- Nominal diameter.
- Pipe class with the suffix LD.
- The prescribed pictorial warning sign.
The STI also refers to a safety-rules sheet accompanying deliveries and warning information in product literature. <Cite refs={["turn847121view2"]}/>
Marking should be implemented only in accordance with the applicable licence conditions and current BIS requirements. A manufacturer must not use the ISI mark before obtaining the necessary authorisation.
7. Documents Required for BIS Certification
The final document checklist depends on the current BIS application requirements, factory setup, product range and testing arrangements. Manufacturers should prepare the following information for initial review.
Business and factory documents
- Legal name and constitution of the manufacturing entity.
- Factory address and ownership, lease or occupancy documents, as applicable.
- GST registration and other applicable business registrations.
- Authorised signatory details and authorisation documents.
- Factory layout and details of manufacturing facilities.
Product and technical documents
- Product description and intended application.
- Pipe class, nominal diameter range and product specifications.
- Relevant technical drawings and manufacturing details.
- Raw-material specifications and supplier details.
- Manufacturing process flow chart.
- Quality-control plan and inspection procedures.
- Product identification and proposed marking details.
Testing and quality-control documents
- List of testing equipment and measuring instruments.
- Calibration certificates and equipment maintenance records.
- Internal test formats and sample test records, where available.
- Details of personnel responsible for testing and inspection.
- Production records, batch or control-unit identification and rejection records.
- Proposed arrangements for tests that cannot be performed in-house, subject to BIS acceptance.
Application-related documents
- Documents and declarations required by the current BIS application system.
- Details of the manufacturing unit and proposed product scope.
- Applicable application fee and other payments as confirmed by BIS.
- Additional documents requested during scrutiny or inspection.
This is a preparation checklist, not a substitute for the latest official BIS application checklist. Additional documents may be required depending on the application.
8. BIS Certification Process for IS 9627:1980
The following is a general preparation and certification workflow. The exact sequence and requirements should be confirmed with BIS for the relevant application.
Step 1: Confirm product applicability
Verify that the product falls under IS 9627:1980 and determine the applicable QCO, amendments, exemptions and certification route.
Step 2: Review the factory and product scope
Assess the proposed pipe classes, sizes, manufacturing facilities, laboratory capability and quality-control arrangements.
Step 3: Prepare the application documents
Compile the required business, factory, technical and testing documentation.
Step 4: Arrange product testing
Identify the applicable tests and prepare samples and facilities according to BIS requirements. Testing and inspection must follow the relevant standard and current certification documents.
Step 5: Complete the BIS assessment
Address application scrutiny, factory assessment, sample testing and any observations or corrective actions required by BIS.
Step 6: Obtain the licence before marking
The manufacturer may use the Standard Mark only after the required authorisation is granted and in accordance with the licence conditions.
Step 7: Maintain ongoing compliance
Continue factory testing, inspection, calibration, records and marking controls as required by the applicable BIS scheme.
9. BIS Certification Fees and Testing Costs
The total cost of certification should be calculated only after confirming the product scope, current BIS fee schedule, required tests and factory readiness.
Potential cost components include:
- BIS application and licence-related fees, as applicable.
- Product testing charges.
- Sample preparation, handling and transportation.
- Testing-equipment procurement or calibration, where required.
- Factory quality-system and documentation preparation.
- Consultancy charges, if professional assistance is engaged.
The BIS Laboratory Information Management System (LIMS) lists testing charges for IS 9627:1980 at an example laboratory, including a displayed total of
₹30,000 excluding taxes. This is a laboratory-specific testing figure, not the total cost of obtaining a BIS licence. Actual charges, test scope, laboratory availability and the applicable fee schedule should be reconfirmed before budgeting. <Cite refs={["turn266335search4","turn266335search6"]}/>
10. How Long Does BIS Certification Take?
The timeline depends on document readiness, laboratory capability, availability of suitable samples, testing outcomes, factory assessment and BIS processing.
There is no single reliable completion time for every IS 9627:1980 application. A realistic project schedule should be prepared after reviewing the factory, product range, testing requirements and current BIS procedure. Missing documents, inadequate testing facilities or failed tests can extend the process.
11. Common Challenges for Manufacturers
Manufacturers may face delays or additional costs if they:
- Select an incorrect standard for the product.
- Submit incomplete factory or technical documents.
- Do not maintain suitable testing and calibration records.
- Fail to establish traceability for production control units.
- Have difficulty meeting hydraulic pressure-tightness or strength requirements.
- Use marking that does not match the applicable licence conditions.
- Assume that a QCO exemption applies without verifying its scope.
A pre-application review can help identify these gaps before formal assessment and testing.
12. Asbestos Safety and Handling Considerations
Asbestos-containing products require careful handling. Manufacturers should implement applicable occupational safety, dust-control, storage, transport and disposal measures, and ensure that the required warnings and safety information are provided.
The BIS STI for this product specifically refers to a safety-rules sheet and prescribed pictorial warnings. Compliance with product certification requirements does not replace any separate environmental, occupational-safety or other statutory obligations that may apply. <Cite refs={["turn847121view2"]}/>
