Champ d’application

This standard specifies the basic safety protection technical requirements, measures, and verification methods for the main hazards of surface grinding machines with horizontal grinding wheel spindle and reciprocating table. It applies to general-purpose machine tools of this category. Manufacturers must ensure compliance with both mandatory and recommended clauses outlined in this standard. It references various foundational standards like GB 15760-2004 and GB/T 15706.1-2007 for risk assessment.

Exigences techniques

The standard comprehensively addresses various hazard categories associated with the equipment. It mandates specific design and protective measures for mechanical hazards, such as crushing, shearing, and ejection of parts, requiring reliable guarding and interlocking mechanisms. For electrical systems, it aligns with GB 5226.1-2002 to prevent electric shock and ensure proper overload protection. Control systems must be designed to prevent unexpected start-up and ensure safe stop functions. Additionally, the standard sets limits for noise levels and temperature extremes to protect operators from physiological harm. It also details requirements for hydraulic and pneumatic systems, ensuring pressure relief valves and leak prevention measures are in place. Ergonomic principles are applied to dictate the dimensions, operating forces, and placement of control devices to minimize human error and strain.

Méthodes d’essai

Verification of compliance involves several methods, including visual inspection, functional checks, and review of technical documentation. Specific tests include protective grounding continuity tests, insulation resistance tests, and dielectric tests for electrical safety. Noise measurement must be conducted according to GB/T 16769, and dust/oil mist concentrations are measured using methods specified in GB/T 23573 and GB/T 23574 respectively. Manufacturers must provide proof of compliance through testing certificates and design drawings.
