T/CHEAA 0035-2024 Resistant Corrosion-resistant Metal-wrapped Nylon Material for Household and Similar Use Electrical Appliances
Basic Information
Scope
Scope: This document specifies the characteristic codes and representation methods, technical requirements, test methods, inspection rules, packaging, marking, transportation, and storage for nylon materials used in corrosion-resistant metal-clad pipes for household appliances and similar applications. This document applies to nylon materials used in corrosion-resistant metal-clad pipes, which are made by adding additives with different functions to nylon resin and then plasticizing, mixing, and granulating it. Main technical contents: This document specifies the appearance, density, melting point, equilibrium water absorption, tensile breaking stress, tensile yield stress, elongation at break, tensile elastic modulus, notched impact strength of a simple beam, Shore hardness (D), melt flow rate (MVR), thermal conductivity, peel strength, resistance to thermal oxidation aging, resistance to high and low temperature impact, resistance to acid corrosion, resistance to moisture and heat aging, and resistance to salt corrosion of nylon materials used in corrosion-resistant metal-clad pipes for household appliances and similar applications, as well as the content of restricted substances.
