Scope

Scope: This document specifies the terms and definitions, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage for computer chassis used in data communication equipment. This document applies to computer chassis (hereinafter referred to as "chassis") and to products that can be installed in chassis meeting the requirements of this document. Main technical content: 4.1 Appearance requirements 4.1.1 Surface requirements The appearance of the chassis should be smooth and flat, without obvious unevenness or mechanical scratches, and without defects such as cracks, burrs, destructive indentations, or severe rust. The surface grade can be divided into A-grade, B-grade, and C-grade according to its importance, as defined in Table 1. Table 1: Definition of surface grades Serial number Surface grade definition 1 A-grade surface The surface that customers can often see in the final use state is an A-grade surface. Examples include: a) The front of the chassis and the top surface of chassis with a height not exceeding 5U; b) The front and rear air ducts of data center products with a height not exceeding 2U. 2 B-grade surface The surface that customers can occasionally see without moving the product is a B-grade surface. Examples include: a) The sides of the chassis and the rear of non-data center products; b) The top surface of chassis with a height greater than 5U. 3 C-grade surface The surface that customers can only see after moving or opening the product is a C-grade surface. Examples include: the bottom surface of the chassis. 4 Internal surface The surface that customers cannot see at the customer's site, such as the internal surface of the chassis. Note: The methods in this document do not apply to the inspection of internal surfaces. 4.1.2 Decorative protective layer requirements The decorative protective layer should meet the following requirements: a) All components should
