IS 11246:1992 is the Indian Standard (BIS) for glass fibre reinforced polyester resins (grp) squatting pans. This standard specifies the requirements for materials, dimensions, construction, workmanship, and performance of Glass Fibre Reinforced Polyester (GRP) squatting pans. It covers aspects like material composition, physical properties such as load resistance and water absorption, and outlines testing methods to ensure product quality. The standard is intended for use by manufacturers and for procurement of GRP sanitary ware.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
Practical Notes
! Ensure the surface finish is smooth, non-porous, and free from cracks or crazing to maintain hygiene and ease of cleaning.
! Verify the manufacturer's test certificate for compliance with performance requirements like load resistance (400 kgf) and Barcol hardness, which are critical for durability.
! While lightweight, GRP pans must be installed on a level and solid base to prevent stress cracking under load during installation and use.

Key Differences
≠IS 11246 is highly prescriptive about material composition, specifying glass content (25-35%) and Barcol hardness. Most international standards are performance-based, allowing any composition that meets functional tests.
≠Modern European standards like BS EN 13407 include detailed functional flushing performance tests (e.g., paper and sawdust removal, surface washing), which are not specified in IS 11246.
≠International standards for composite sanitary ware (e.g., EN 14296) often mandate thermal shock/cycling tests (e.g., 100 cycles between 15°C and 75°C), which is more rigorous than the static boiling water test in IS 11246.
≠IS 11246 provides specific dimensional patterns (e.g., 580 mm length), whereas EN standards typically do not specify overall dimensions, focusing instead on interchangeability of connections and functional ergonomics.
Key Similarities
≈Both IS 11246 and equivalent performance standards (like BS EN 13407) mandate a static load test to ensure the pan can withstand the user's weight without failure.
≈A universal requirement across IS 11246 and international counterparts is the need for a smooth, non-porous, and easily cleanable surface to ensure hygiene and prevent microbial growth.
≈All related standards require the finished product to be resistant to staining and chemical attack from common household cleaning agents and toiletries.
≈Both the IS code and international standards for plastic/composite sanitary ware specify limits on water absorption to ensure long-term dimensional stability and material integrity.
