T/CSTE 0105-2021 "Leader" standard evaluation requirements for aluminum alloy guide wheels used in wire and cable equipment

Scope

Scope: This document specifies the terms and definitions, evaluation index system, evaluation methods, and grade classification for the "Leader" standard evaluation of aluminum alloy guide wheels used in wire and cable equipment. This document applies to aluminum alloy guide wheels with a diameter of 20mm to 1000mm, where the diameter should include the thickness of the surface treatment layer, and the evaluation of the enterprise standard level of guide wheel products. Relevant institutions can refer to and use this document when formulating the "Leader" evaluation scheme for enterprise standards. Enterprises can also refer to and use this document when formulating their own enterprise standards. Main technical content: 4.2 Classification of evaluation indicators 4.2.1 The "Leader" standard evaluation indicators for aluminum alloy guide wheels used in wire and cable equipment include basic indicators and core indicators. 4.2.2 Basic indicators include chemical composition, surface quality, and dimensional geometric tolerances. 4.2.3 Core indicators include radial runout, end face runout, dynamic balance accuracy, and surface roughness. The core indicators are divided into three levels: - Advanced level, equivalent to the 5-star level in the enterprise standard ranking list; - Average level, equivalent to the 4-star level in the enterprise standard ranking list; - Benchmark level, equivalent to the 3-star level in the enterprise standard ranking list.
