Asbestos - Cement pipes and fitkIngs for sewerage and drainage — IS 6908 (1991) Testing

IS 6908:1991 applies to asbestos-cement pipes and fittings designed for sewerage and drainage systems where flow takes place by gravity under atmospheric pressure. Manufacturers should confirm the exact product type and scope before selecting this standard for testing or certification.

Testing according to IS 6908:1991 helps manufacturers establish conformity with the applicable Indian Standard requirements. It can support product quality assurance, customer specifications, tender requirements and the BIS conformity-assessment process where certification is applicable.

The standard establishes requirements relating to asbestos-cement sewerage and drainage pipes and fittings, including relevant product characteristics, dimensions, joints and testing provisions. Conformity is evaluated according to the applicable requirements specified in the standard and BIS certification documentation.

Yes. IS 6908:1991 is specifically intended for asbestos-cement pipes and fittings used in sewerage and drainage applications. Its scope is focused on systems operating under gravity flow and atmospheric pressure rather than pressurised pipeline applications.

Yes. Testing to IS 6908:1991 can form part of the conformity-assessment process for products covered by the corresponding BIS certification requirements. Manufacturers generally need to meet the applicable product, factory-control, inspection and testing provisions prescribed by BIS.

Depending on the laboratory and certification requirement, manufacturers may need to provide product specifications, drawings, technical details, declared dimensions, sample information and relevant manufacturing details. Additional documentation may be required when testing is being performed specifically for a BIS licence application.

Samples should be tested at a laboratory capable of performing the relevant requirements of IS 6908:1991 and, where required, having the appropriate accreditation or recognition for the applicable tests. Certko can help businesses coordinate testing with suitable laboratories based on the product and compliance requirement.

Compliance is verified by assessing the product against the applicable requirements of IS 6908:1991 through specified inspection and testing procedures. The results are compared with the standard's requirements to determine whether the tested product conforms to the relevant criteria.
