Scope
Scope: This document applies to the testing of waterproofing materials for their combustion performance, water resistance, thermal aging, accelerated aging in artificial climate, seam peel strength, waterproofness of lap joints, durability in corrosive media, anti-seepage pressure of mortar specimens, bonding strength, frost resistance, and water absorption, among other engineering requirements. This document does not apply to the basic performance testing of waterproofing membranes, waterproofing coatings, and cement-based waterproofing materials. Main technical content: 1. General provisions: Where the testing methods for relevant engineering requirements are clearly specified in the corresponding national or industry standards, they shall be implemented in accordance with these standards; where there are no corresponding national or industry standards, or where the provisions of the national or industry standards do not conform to this document, they shall be implemented in accordance with this document. 2. Standard test conditions: - Standard test conditions for waterproofing membranes: Temperature (23±2)°C, relative humidity (30–70)%. - Standard test conditions for waterproofing coatings: Temperature (23±2)°C, relative humidity (50±10)%. - Curing conditions for cement-based waterproofing materials: Temperature (20±3)°C, relative humidity not less than 90%; curing pool conditions: Temperature (20±2)°C; standard test conditions: Temperature (23±2)°C. 3. Test processing conditions: - The test processing temperatures for thermal aging, water immersion, and durability in corrosive media specified in this document are minimum requirements. Higher temperatures may be used. - The test processing times specified in this document are minimum requirements. Longer times may be used. 4. Preparation and curing of waterproofing membrane and waterproofing coating specimens: - Samples and all equipment shall be placed under standard test conditions for at least 24 hours befor
