Scope

Scope: This standard specifies the terms and definitions, marking, general requirements, technical requirements, test methods, inspection rules, and marking, packaging, transportation, and storage for non-curing rubber asphalt waterproofing coatings (hereinafter referred to as non-curing waterproofing coatings). This standard applies to non-curing rubber asphalt waterproofing coatings used for non-exposed waterproofing in construction projects. Main technical contents: - Appearance: The product should be uniform, free from lumps, and without visible impurities. - Flash point/℃ ≥ 180 - Solid content/% ≥ 98 - Adhesion performance (on dry substrates and damaged/wet substrates): 100% cohesive failure - Tensile elongation/mm ≥ 15 - Low-temperature flexibility: -20℃, no cracking - Heat resistance/65℃: no sliding, dripping, or flow - Thermal aging (70℃, 168h): tensile elongation/mm ≥ 15 - Low-temperature flexibility: -15℃, no cracking - Acid resistance (2% H2SO4 solution): no change in appearance - Tensile elongation/mm ≥ 15 - Mass change/% ± 2.0 - Alkali resistance [0.1% NaOH + saturated Ca(OH)2 solution]: no change in appearance - Tensile elongation/mm ≥ 15 - Mass change/% ± 2.0 - Salt resistance (3% NaCl solution): no corrosion after 24h immersion - Water resistance (immersion in water for 24h): no leakage or dripping - Impact resistance (drop test from 1m): no cracking or deformation - Flammability (B1 level): no ignition or flame propagation - Electrical insulation (1kV/mm): no breakdown or arcing - Environmental protection (VOC content): ≤ 300g/L - Packaging: in sealed containers - Transportation: by road, rail, or air - Storage: in a cool, dry place, away from direct sunlight and moisture.
