Basic Information
Scope
Main technical content: This standard specifies the terms and definitions, models and basic parameters, basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, and quality commitments for handheld flat sanding machines. This standard applies to general environmental conditions. It uses AC/DC dual-use or single-phase series-excited motors to drive eccentric mechanisms, converting rotary motion into swinging motion. The handheld electric swinging flat sanding machines (hereinafter referred to as sanding machines) are equipped with corundum or other abrasive sandpaper (or sand cloth) on a flat plate to sand the surfaces of wood, metal materials, etc. This standard does not apply to swinging flat sanding machines driven by single-phase asynchronous squirrel-cage motors or battery-powered sanding machines.
