Scope
This document specifies the naming rules, technical requirements, test methods, inspection rules, marking, packaging, transportation, storage, and quality certificates for nylon 12 and its composite powders used in powder bed fusion. This document applies to nylon 12 powders used in powder bed fusion, as well as glass microbead-reinforced nylon 12 composite powders, carbon fiber-reinforced nylon 12 composite powders, aluminum powder-reinforced nylon 12 composite powders, and mineral fiber-reinforced nylon 12 composite powders. Other nylon 12 composite powders can refer to this document. Note: The nylon 12 composite powders referred to in this document include powders compounded between particles, that is, powders compounded between particles or particles and fibers in a powder state; it also includes powders compounded within particles, that is, powders prepared by compounding raw materials (a single particle is a composite powder).
