26、 extent to which hazards, hazardous situations and events are covered are defined in the Scope of this part of ISO 11148. When requirements of this type-C standard are different from those which are stated in type-A or -B standards, the requirements of this type-C standard take precedence over the r
27、equirements of other standards for machines that have been designed and built according to the requirements of this type-C standard.ISO 11148 consists of a number of independent parts for individual types of hand-held non-electric power tools.Certain parts of ISO 11148 cover hand-held non-electric p
28、ower tools driven by internal combustion engines powered by gaseous or liquid fuel. In these parts, the safety aspects relating to internal combustion engines are found in a normative annex.The parts are type-C standards and refer to pertinent standards of type A and B where such standards are appli

For the purposes of colour matching, see ISO 3864-4, which provides colorimetric and photometric properties together with, as a guideline, references from colour order systems.1 ScopeThis part of ISO 11148 specifies safety requirements for hand-held non-electric power tools (hereinafter “
31、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 operators hand or hands, with or with
32、out 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 intende
33、d 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 winds
34、hield 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 1114
35、8 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 recipro
36、cating 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 e
37、quipment for potentially explosive atmospheres.2 Normative referencesThe following referenced documents are indispensable for the application of this document.
