2. Is BIS Certification Mandatory for IS 13000:1990?

BIS includes IS 13000:1990 in the Scheme-I category for asbestos or fibre cement-based products associated with the Asbestos or Fibre Cement Based Products (Quality Control) Order, 2024. <Cite refs={["turn791879search0","turn791879search25"]}/> Under a Quality Control Order (QCO), covered products are subject to the applicable conformity and Standard Mark requirements, subject to the precise terms of the order and any valid exemptions. Manufacturers, importers and suppliers should verify the current legal position before manufacturing, importing, selling or supplying these products. Important points to check include:

Whether the product falls within the scope of IS 13000:1990 and the applicable QCO.
Whether the relevant product must carry the BIS Standard Mark.
Whether any specific exemption applies to the manufacturer, importer, purchaser or intended use.
Whether subsequent amendments or government orders affect the proposed transaction.

The BIS product listing refers to orders dated 13 February 2026 concerning exemptions against import and purchase for the broader product category. Their applicability must be assessed against the exact order and transaction; they should not be treated as a blanket exemption for all products or businesses. <Cite refs={["turn791879search0"]}/>

3. Product Classification and Licence Scope

The BIS product manual for IS 13000:1990 identifies the following scope parameters for licensing:

Product: Silica-Asbestos-Cement Flat Sheets.
Class of sheet: Class 1 or Class 2.
Nominal thickness: Defined by the approved licence scope, up to the applicable specified limit.

The manual indicates that the licence scope should state the approved class and nominal thickness range. <Cite refs={["turn791879search21"]}/> Before applying, manufacturers should identify:

The class or classes of sheets being manufactured.
The nominal thicknesses and dimensions in the proposed range.
The manufacturing process and raw materials.
The product variants that need to be covered by the licence.

The exact grouping and scope extension should be determined using the current BIS product manual and applicable certification requirements.

4. Raw Materials and Manufacturing Requirements

The BIS product manual refers to raw materials including cement, asbestos fibre or pozzolanic material, fillers, pigments and colouring materials, as applicable to the relevant clauses of IS 13000:1990. <Cite refs={["turn791879search21"]}/> Manufacturers should maintain suitable controls for incoming materials and production consistency.

Raw-material documentation

Prepare relevant information such as:

Cement type and specifications.
Asbestos fibre and other permitted material specifications.
Details of pozzolanic materials, fillers and pigments used.
Supplier details and incoming-material inspection records.
Batch or lot identification and traceability.
Internal material acceptance and rejection records.

The precise material requirements must be verified against the applicable clauses of the official Indian Standard. Alternative materials should not be assumed acceptable without checking the standard and obtaining any required confirmation.

5. BIS Testing Requirements for IS 13000:1990

Testing is a central part of certification. The standard and its associated product manual identify checks intended to evaluate sheet dimensions, physical characteristics, mechanical strength and finished-product quality. Relevant tests and inspections include the following, subject to the applicable standard and test method.

5.1 Dimensional inspection

Dimensional checks verify that sheets conform to the specified measurements and tolerances. These checks can include nominal length and width, thickness and other dimensions specified by the standard. The first amendment to IS 13000:1990 includes updates relating to nominal sheet dimensions and the test for thickness. <Cite refs={["turn791879search22"]}/>

5.2 Bending strength

Bending strength is an important mechanical property used in the classification and evaluation of these sheets. Testing determines whether the product meets the applicable requirements for its class.

5.3 Density

Density testing helps assess the physical characteristics of the sheet against the relevant specification.

5.4 Thickness, straightness and squareness

Thickness measurement, straightness and squareness checks help verify dimensional conformity and consistency between manufactured sheets.

5.5 General appearance and quality

Finished sheets should be examined against the relevant requirements for appearance, workmanship and conformity. The official standard and current testing documents must be consulted for the exact test methods, conditioning requirements, acceptance limits and sampling rules. <Cite refs={["turn791879search22","turn791879search23"]}/>

6. Sample Quantity for BIS Certification

The BIS product manual PM/IS 13000/1/June 2020 specifies a sample size of 3 sheets for the product. <Cite refs={["turn791879search21"]}/> Before arranging samples, the manufacturer should confirm:

The current sample quantity and sampling instructions.
The class and nominal thickness represented by the samples.
The required dimensions and identification of each sample.
The tests to be performed and the applicable grouping guidelines.
Whether additional samples or production units are required for the proposed scope.

The sample requirement in the cited manual is a useful planning reference. Manufacturers should verify that it remains applicable to their intended application and the latest BIS instructions.

7. Factory and Laboratory Requirements

The BIS product manual states that, when it was prepared, testing facilities were not available in BIS or BIS-recognised laboratories for this product and complete testing had to be carried out in the factory. <Cite refs={["turn791879search21"]}/> This makes factory testing capability a key issue during certification preparation. Manufacturers should assess:

BIS application and licence-related fees, as applicable.
Sample preparation and transportation.
Testing equipment procurement or upgrades.
Calibration and maintenance of instruments.
Factory documentation and quality-control preparation.
Consultancy charges, if professional assistance is engaged.

The BIS product manual describes the testing arrangements for this product, but a single testing or consultancy figure should not be treated as the total cost of certification. A project-specific estimate should be prepared after reviewing the factory, proposed sheet class, thickness range, equipment availability and current BIS requirements.

11. How Long Does BIS Certification Take?

The certification timeline depends on the completeness of the application, factory readiness, testing capability, sample conformity, factory assessment and BIS processing. No single completion time can be guaranteed for every application. Delays may occur if the manufacturer needs to procure equipment, improve quality-control procedures, repeat tests or address observations raised during assessment. A realistic timeline should be developed after the initial technical review.

12. Common Challenges During Certification

Manufacturers may encounter difficulties when:

The applicable standard or product classification is incorrectly identified.
The proposed licence scope does not clearly define class and thickness.
Testing facilities are incomplete or unsuitable.
Calibration records and internal test reports are unavailable.
Raw-material traceability is inadequate.
Samples fail dimensional or mechanical requirements.
The factory's production controls are not adequately documented.
The manufacturer assumes an exemption applies without reviewing its exact terms.

A pre-application review can help identify gaps before formal assessment and reduce avoidable delays.

13. Asbestos Safety and Handling Requirements

Asbestos-containing products require careful handling because inhalation of airborne asbestos fibres can cause serious health harm. Manufacturers should implement applicable workplace safety and dust-control measures and ensure appropriate handling, storage, transport and disposal procedures. Workers involved in manufacturing, cutting, handling or maintenance should follow relevant safety requirements. The official IS 13000 standard references guidance on the safe use of asbestos cement products and pictorial warning information for asbestos-containing products. <Cite refs={["turn791879search23"]}/> BIS product certification does not replace separate environmental, occupational-safety or other statutory obligations that may apply to the business.
