GB/T 32800.8-2023 Hand-held non-electric power tools - Safety requirements - Part 8: Sanders and polishers 1 Scope This document specifies safety requirements for hand-held non-electric power tools (hereinafter “sanders and polishers”) intended for polishing and sanding with all types of movement, e.g. rotary, orbital and reciprocating, using coated abrasive products, bonnets of various soft materials and endless belts. The sanders and polishers can be powered by compressed air, hydraulic fluid or internal combustion engines and are intended to be used by one operator and supported by the operator's hand or hands, with or without a suspension, e.g. a balancer. Note 1: At the time of publication, no sanders and polishers driven by internal combustion engines are known. Once these are identified, it is intended to amend this document to include such power tools. This document is applicable to: ——belt sanders; ——orbital sanders; ——polishers; ——random orbital sanders; ——rotary sanders; ——straight-line sanders. Note 2: For examples of sanders and polishers, see Annex B. This document is not applicable to special requirements and modifications of sanders and polishers for the purpose of mounting them in a fixture. This document deals with all significant hazards, hazardous situations or hazardous events relevant to sanders and polishers when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer, with the exception of the use of sanders and polishers in potentially explosive atmospheres. Note 3: EN 13463-1 gives requirements for non-electrical equipment for potentially explosive atmospheres. 2 Normative references The following referenced documents are indispensable for the application of this document.

Hand-held power tools driven by hydraulic liquid are called hydraulic tools. 3.1.2 inserted tool tool inserted in the sander or polisher to perform the intended work 3.1.3 service tool tool for performing maintenance or service on the sander or polisher 3.1.4 control device device to start and stop the sander or polisher or to change the direction of the rotation or to control the functional characteristics, such as speed and power 3.1.5 start-and-stop device throttle manually operated control on the sander or polisher by which the energy supply to the motor can be turned on and off 3.1.6 hold-to-run start-and-stop device constant pressure throttle start-and-stop device which automatically returns to the OFF position when force on the start-and-stop device actuator is released 3.1.7 lock-on start-and-stop device constant pressure throttle with instant release lock hold-to-run start-and-stop device which can be locked in the ON position and which is designed so that it permits the sander or polisher to be turned off by a single motion of the same finger or fingers used to turn it on 3.1.8 lock-off start-and-stop device lock-off throttle start-and-stop device that automatically latches in the OFF position when the actuator is released and where two motions are required to energize the sander or polisher 3.1.9 positive on-off start-and-stop device positive on-off throttle start-and-stop device that remains in the ON position until it is manually changed 3.1.10 maximum operating pressure maximum pressure at which a sander or polisher may be operated 3.1.11 whip hose air hose connecting the main air hose with an air tool for the purpose of providing more flexibility 3.1.12 rated air pressure air pressure, required at an air tool inlet port to ensure rated performance of the tool, also considered the maximum pressure at which the tool may be operated 3.1.13 rated speed 〈pneumatic tool〉 speed of an air tool at no load and rated air pressure at the tool inlet port 〈hydraulic tool〉 nominal speed of a hydraulic tool at no load and rated flow at the tool inlet port Note: The rated speed is expressed in revolutions per minute. 3.1.14 maximum attainable speed maximum speed which the tool can achieve under the most adverse condition of possible maladjustment or malfunction of its speed control devices, when supplied with compressed air at the pressure marked on the sander or polisher 3.1.15 suspension device device, which is attached to the tool, whose primary purpose is to reduce the strain on the operator caused by the weight of the tool Note: The device can also have a secondary purpose of transmitting a reaction torque.
