Escopo e aplicabilidade

This standard applies to the safeguarding specifications for general-purpose table-moving external cylindrical grinding machines. It is designed for manufacturers and engineers involved in the design, manufacturing, and maintenance of these machine tools. Compliance with this standard is mandatory for relevant machinery entering the Chinese market. It does not cover specialized grinding machines not specified in the scope.

Requisitos técnicos

The standard outlines comprehensive safety requirements to mitigate major hazards associated with external cylindrical grinding machines. It categorizes potential hazards including mechanical dangers (such as crushing, shearing, and entanglement), electrical hazards, thermal risks, and noise exposure. Manufacturers must implement design measures to eliminate or reduce these risks. For the control systems, the standard specifies requirements for safety-related parts, including start, stop, and emergency stop functions, ensuring they meet specific categories as defined in GB/T 16855.1. It also details the necessity of reliable interlocking devices and protective guards to prevent accidental access to danger zones during operation. Control systems must be designed to prevent unexpected start-up and ensure safe stopping. Additionally, the standard addresses ergonomic principles, requiring proper design of operating handles, buttons, and display devices to minimize operator fatigue and human error. It also sets limits on noise levels and specifies requirements for hydraulic, pneumatic, and lubrication systems to prevent failures that could lead to hazardous situations. All safety measures must be validated through specified verification methods.

Métodos de ensaio

Verification methods include visual inspections, functional checks, and specific measurements. Key testing involves noise level measurement according to GB/T 16769, protective grounding continuity tests, and insulation resistance tests for electrical equipment. The standard also requires checking the functionality of interlocking devices and verifying the operating forces and installation heights of control elements.
