JIS G3492 is a technical specification for tar asphalt protective coatings on steel water pipes in Japanese industrial standards, and is a non mandatory national standard. This standard specifies the technical requirements, construction methods, and performance testing of coating materials, and is applicable to the internal and external anti-corrosion protection of steel water pipelines. Users can download the first three pages of the standard for free through relevant platforms, but obtaining the complete version requires contacting designated institutions for purchase.
Application areas and related products
This standard is widely used in engineering practice for the anti-corrosion protection of steel water pipelines, especially in industrial equipment such as high-pressure vessels and gas cylinder pipes, and has important reference value. The manufacturing and testing of some testing instruments, such as spark detectors and insulation detectors, must comply with JIS G3492 standards to ensure the integrity of coating insulation performance and prevent current leakage or safety hazards caused by insulation defects.
Testing methods and technical requirements
According to standard requirements, coating testing should include multiple indicators such as chemical composition analysis, thickness measurement, and corrosion resistance testing. For example, when using an electric spark detector to verify the insulation properties of coatings, it is necessary to meet the voltage and current parameters specified in JIS G3491 and JIS G3492, and conduct a comprehensive evaluation in conjunction with international standards such as ANSI/AWWAC214-89. In addition, the standard also involves the environmental adaptability (such as temperature and humidity range) and long-term durability requirements of coating materials.
