IS 3367:1993 is the Indian Standard (BIS) for burnt clay tiles for use in lining irrigation and drainage works-specification. This standard specifies the dimensions, physical requirements, and testing criteria for burnt clay tiles used in lining irrigation canals and drainage systems to prevent water seepage.

Vitrified clay pipes
Specified requirements for vitrified clay pipes and fittings for drainage and sewerage, similar in scope to EN 295.
Key Differences
≠The primary form factor in IS 3367 is a flat or curved tile for open channel lining, whereas standards like ASTM C4 and EN 295 specify cylindrical pipes for enclosed, often buried, drainage or sewerage.
≠IS 3367 specifies flexural strength (modulus of rupture) as the key mechanical property, which is appropriate for a flat tile. In contrast, ASTM C4 and EN 295 mandate crushing strength, relevant for pipes resisting external soil and traffic loads.
≠EN 295 requires 'vitrified clay,' a higher-grade material fired to the point of near-zero porosity, making it stronger and less absorptive than the 'burnt clay' specified in IS 3367.
≠The water absorption limit in IS 3367 (15%) is significantly higher than in standards for drainage pipes like ASTM C4 (11-13% for different classes) or vitrified pipes (typically <6%), reflecting a less demanding application (lining vs. load-bearing pipe).
Key Similarities
≈All standards use fired natural clay as the fundamental raw material for manufacturing the products.
≈The core purpose across all standards is water management, either by lining channels to prevent seepage (IS 3367) or by conveying water in drainage/sewer systems (ASTM C4, EN 295).
≈Control of water absorption is a critical performance parameter in all the standards, as it directly relates to the durability and frost resistance of the clay product.
≈All standards include clauses for visual inspection, requiring products to be reasonably free from defects like cracks, chips, and warpage that would impair their function.
