Hand-held non-electric power tools. Safety requirements. Circular, oscillating and reciprocating saws | Status: Current, Confirmed

1 Scope This part of ISO 11148 specifies safety requirements for hand-held non-electric power tools (hereinafter “circular, oscillating and reciprocating saws”) intended for sawing. The circular, oscillating and reciprocating saws 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 circular, oscillating or reciprocating saws driven by internal combustion engines are known [other than circular saws with bonded abrasives and/or super abrasives (diamond) cut-off wheels]. Once these are identified, it is intended to amend this part of ISO 11148 to include such power tools.

This part of ISO 11148 is applicable to

• — circular saws;
• — circular knives;
• — oscillating saws having a saw blade with a radius of 50 mm or less or a diamond cutting-off blade with a radius of 100 mm or less;
• — oscillating knives (including windshield knives);
• — reciprocating saws, including jig saws and power hack saws.

NOTE 2 For examples of circular, oscillating and reciprocating saws, see Annex B.

NOTE 3 For circular saws with bonded-abrasive and/or super-abrasive (diamond) cut-off wheels, see ISO 11148-7 and ISO 19432.

This part of ISO 11148 is not applicable to special requirements and modifications of circular, oscillating and reciprocating saws for the purpose of mounting them in fixtures. This part of ISO 11148 deals with all significant hazards, hazardous situations or hazardous events relevant to circular, oscillating and reciprocating saws 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 circular, oscillating and reciprocating saws in potentially explosive atmospheres.

NOTE 4 EN 13463-1 gives requirements for non-electrical equipment for potentially explosive atmospheres.
