International Standards for Chemical Hoses

Chemical hoses are essential for industries that require the movement of hazardous substances, such as acids, alkalis, and solvents. These hoses must meet strict international standards to ensure their effectiveness and safety. In this article, we will discuss the international standards for chemical hoses. EN 12115 EN 12115 is an European standard that specifies the requirements for chemical hoses and their assemblies. This standard covers hoses that are designed to handle a wide range of chemicals, including acids, alkalis, and organic compounds. EN 12115 hoses must be able to withstand a minimum temperature of -20°C and a maximum temperature of 65°C. ISO 2928 ISO 2928 is an international standard that specifies the requirements for rubber and plastic hoses for use with compressed air. This standard covers hoses that are designed to handle air and a limited range of chemicals, including oil and water. ISO 2928 hoses must be able to withstand a minimum temperature of -40°C and a maximum temperature of 70°C. ASTM D380 ASTM D380 is an American standard that specifies the requirements for rubber hoses used in the transfer of liquid petroleum gas (LPG). This standard covers hoses that are designed to handle propane, butane, and other liquefied petroleum gases. ASTM D380 hoses must be able to withstand a minimum temperature of -40°C and a maximum temperature of 70°C. Conclusion In conclusion, international standards for chemical hoses ensure their effectiveness and safety in the handling of hazardous substances. EN 12115 is a European standard that covers hoses designed to handle a wide range of chemicals, ISO 2928 is an international standard that covers hoses designed for compressed air, and ASTM D380 is an American standard that covers hoses designed for liquid petroleum gas. It is important to choose the appropriate standard for the specific application and environment to ensure the safety and effectiveness of chemical hoses.
