ASTM D312-21ASTM International, USA
MediumCurrent
Standard Specification for Asphalt Used in Roofing

Joint fillers and sealants - Part 1: Specifications for hot applied sealants
Focuses on hot-applied joint sealants, which is functionally equivalent to IS 1580's Type 3 (Caulking Grade).
ASTM D6690-23aASTM International, USA
MediumCurrent
Standard Specification for Joint and Crack Sealants, Hot-Applied, for Concrete and Asphalt Pavements
Details requirements for hot-applied pavement joint sealants, analogous to the caulking application in IS 1580.
Key Differences
≠IS 1580 classifies materials into three generic types (Normal, Special, Caulking), whereas standards like ASTM D449 and D312 classify types based on specific application areas (e.g., below-grade vs. above-grade, or roof slope).
≠Modern international sealant standards (e.g., ASTM D6690, BS EN 14188-1) include performance tests like bond strength, resilience, and flow resistance, which are not specified for the 'Caulking Grade' in the older IS 1580.
≠IS 1580 specifies a ductility test at 27°C, reflecting Indian climatic conditions. Most ASTM standards specify ductility testing at 25°C.
≠Ductility requirements are vastly different; for example, IS 1580 Type 1 requires a minimum of 3 cm, while the comparable ASTM D449 Type I requires a minimum of 30 cm, indicating a significant difference in material elasticity expectations.
≠IS 1580 is prescriptive, specifying only trichloroethylene for solubility tests. ASTM D449, while also old, acknowledges alternatives like toluene (with different acceptance criteria), reflecting a slight move toward flexibility.
Key Similarities
≈All standards are fundamentally for hot-applied bituminous or asphaltic compounds intended for waterproofing, sealing, or roofing.
≈The core classification of material grades in both IS 1580 and its ASTM equivalents relies on the same fundamental physical properties: Softening Point and Penetration.
≈Basic quality and safety control tests, such as Flash Point (for heating safety) and Loss on Heating (for material stability at application temperature), are common requirements across all standards.
≈All standards cover materials that are solid or semi-solid at ambient temperature and require heating to a fluid state for application.
