This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 2006/42/EC, and which apply to hand-held non-electric power tools that are either first placed on the market or commissioned within the EEA. This standard
8、serves to facilitate proof of compliance with the essential requirements of the directive. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of th
9、e Machinery Directive (“presumption of conformity”). For the International Standards referred to in this document there are no national standards available unless they have been published as DIN EN, DIN EN ISO or DIN ISO standards with the same number. Amendments This standard differs from DIN EN 79
10、2-8:2009-12 as follows: a) the text of ISO 11148-8 has been adopted in its entirety; b) technical requirements of ANSI B.186.1 and references to EN ISO 12100 have been incorporated; c) vibration total values and noise-emission values and their uncertainties are to be declared; d) technical requireme
11、nts have been brought in line with EN 60745 (IEC 60745); e) user instructions are to include further and more detailed safety instructions.

28、) DIN EN ISO 11148-8:2012-06 3 Introduction This document is a type-C standard as stated in ISO 12100. The machinery concerned and the 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 ar
29、e different from those which are stated in type-A or -B standards, the requirements of this type-C standard take precedence over the requirements 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
30、 independent parts for individual types of hand-held non-electric power tools. Certain parts of ISO 11148 cover hand-held non-electric power tools driven by internal combustion engines powered by gaseous or liquid fuel. In these parts, the safety aspects relating to internal combustion engines are f
31、ound in a normative annex. The parts are type-C standards and refer to pertinent standards of type A and B where such standards are applicable.

32、n nor printed as true representations. 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 Scope This part of ISO 11148 specifies safety requirements for hand-held non-elect
33、ric 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
34、, 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 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
35、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: belt sanders; orbital sanders; polishers; random orbital sanders; rotary sanders; straight-line sanders. NOTE 2 For examples of sanders and polishers, see Annex
36、B. This part of ISO 11148 is not applicable to special requirements and modifications of sanders and polishers for the purpose of mounting them in a fixture. This part of ISO 11148 deals with all significant hazards, hazardous situations or hazardous events relevant to sanders and polishers when the
37、y 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 atmosph
