This document is under the jurisdiction of the National Technical Committee on Standardization of Light Industrial Machinery (SAC/TC101).

1 Scope

This document defines the terminology related to light industrial machinery, provides model numbers for ease of technical specification, and stipulates basic requirements, design and layout, and materials.

Materials, processing and assembly, completeness, hydraulics, pneumatics and lubrication, electrical and automation, intelligence, safety, service life and reliability, energy saving Environmental protection, appearance quality, function and performance, inspection rules, marking, packaging, transportation and storage, and corresponding test methods are described.

This document applies to the design and manufacture of single machines, unit operating devices, and production lines for light industrial machinery (the above three categories are collectively referred to as "equipment").

Manufacturing, installation, inspection, and acceptance can also serve as the basis for trade contracts between suppliers and buyers, and for certification bodies. Similar machinery is applicable.

When doing so, please refer to this document.
