of which is held by din.this european standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by november 2008, and conflicting national standards shall be withdrawn at the latest by november 2008.this document has been prepared under a mandate given to cen by the european commission and theeuropean free trade association, and supports essential requirements of eu directives 98/37/ec and2006/42/ec.for relationship with eu directive(s) see informative annexes za and zb, which are an integral part of this document.attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. cen and/or cenelec shall not be held responsible for identifying any or all such patent rights.according to the cen/cenelec internal regulations, the national standards organizations of the following countries are bound to implement this european standard: austria, belgium, bulgaria, cyprus, czech republic, denmark, estonia, finland, france, germany, greece, hungary, iceland, ireland, italy, latvia, lithuania, luxembourg, malta, netherlands, norway, poland, portugal, romania, slovakia, slovenia, spain, sweden, switzerland and united kingdom.introductionthis standard is a type c standard as stated in en iso 12100.the machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this standard.when provisions of this type c standard are different from those which are stated in type a or b standards, the provisions of this type c standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type c standard.1scopethis standard applies to positive displacement refrigerant compressors for stationary and mobile refrigerating systems and heat pumps defined in 3.1, hereafter called compressors.it applies for compressors used in commercial and industrial appliances and with electrical energy supply including integral motors, up to 1 000 vac and 1 500 vdc.it applies to open drive, semi hermetic and hermetic motor compressors, which contain a positive compression function.this standard is not applicable to: compressors used in household appliance for which en 60335-2-34 applies; compressors using water or air as refrigerant.this standard does not deal with requirements for vibration and noise.note 1compressors for automotive comfort air conditioning systems can be developed according e.g. sae j 639. note 2noise emission depends on the complete installation of the built-in compressors and the correspondingoperating conditions.for semi-hermetic and open drive compressors which include moving parts and for which the external envelope is primarily designed for mechanical loads, thermal loads (to limit the possible deformation due to temperature), stiffness of the structure (external mechanical loads and weight of the equipment), taking into account established safe industrial practice, it is considered that pressure is not a significant design factor.attached parts covering other functions e.g. oil separators, oil coolers, suction accumulators shall comply to en 14276-1 or en 13445-6 (cast iron) or en 13445-8 (aluminium) or showing compliance to the relevant european requirements. this applies also to shells for hermetic compressors either welded or with any kind of permanent joint.requirements for compressors used in explosive atmospheres are not covered by this standard.note 3for further guidance see en 13463-1.this standard deals with all significant hazards, hazardous situations and events relevant to compressors, when they are used as intended and under conditions for misuse which are reasonably foreseeable by the manufacturer (see clause 4).this standard specifies safety requirements for the design, construction, manufacture and testing, documentation and marking of compressors, including integral accessories, e.g. shut-off valve, if necessary.the requirements in this standard take account of the intended use, as defined in 3.12 of en iso 12100-1:2003.this standard relates to the compressor itself which is to be incorporated in a refrigerating system.this standard is not applicable to compressors as defined in the scope which are manufactured before the date of publication as en.2normative referencesthe following referenced documents are indispensable for the application of this document. for dated references, only the edition cited applies. for undated references, the latest edition of the referenced document (including any amendments) applies.en 287-1, qualification test of welders fusion welding part 1:
