T/CQPRA 0100-2026 Quality Standard for Molding Process of Non-metallic Electric Energy Metering Boxes
T/CQPRA 0100-2026 Quality Standard for Molding Process of Non-metallic Electric Energy Metering Boxes
Basic Information
Scope
This document is applicable to the molding and quality control of electric energy metering box shells and their structural components primarily made of non-metallic materials such as engineering plastics and composite materials. It can be used as a reference by production enterprises, inspection institutions, and relevant management units in the design, manufacturing, inspection, and quality management processes. This document is not applicable to the manufacturing and quality control of metal electric energy metering boxes and related products. This document specifies the quality control requirements for the molding process of electric energy metering boxes (non-metallic) during production, including raw material and formula control, molding process parameters, mold design and use, molding process control, product quality requirements, inspection and testing methods, quality control and traceability, detection and calibration, as well as data management and continuous improvement.
