12、certification procedures. It is recommended that the quality management system conforms to or is no less stringent than the relevant requirements to EN ISO 9001. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for

13、 its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

17、 Requirements for bodies certifying products, processes and services (ISO/IEC 17065) 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 295-2:2013 and the following apply. 3.1 certification body third party assessment body operating certification schemes

18、 Note 1 to entry: A certification body can be non-governmental or governmental (with or without regulatory authority). Note 2 to entry: A certification body is preferably accredited to EN ISO/IEC 17021 and EN ISO/IEC 17065. PD CEN/TR 16626:2014CEN/TR 16626:2014 (E) 5 4 General This document contains

19、 the conditions for the assessment of conformity of any single product to EN 295-1, EN 295-4, EN 295-5, EN 295-6 and EN 295-7. However, in order to make an assessment of conformity of a full range of products coming off a production line, more elements are needed for such as a certification scheme.

20、This certification scheme can be required by contractual agreements for example. It is independent from the strict assessment and verification of constancy of performance procedures as given in EN 295-1:2013, ZA.2, EN 295-4:2013, ZA.2, EN 295-5:2013, ZA.2, EN 295-6:2013, ZA.2, and EN 295-7:2013, ZA.

21、2. Unless there is a certification scheme in place, the following clauses represent the best way to assess the conformity of a range of products to the EN 295 series of product standards. 5 Inspection, audits and certification Conformity assessment is carried out by a certification body at least twi

22、ce a year without prior notice. Third party assessors comply with EN ISO/IEC 17021 and EN ISO/IEC 17065 or equivalent. The assessors undertake the following tasks: inspections of the factory production control established and documented by the manufacturer according to EN 295-2:2013, 5.3; checks of

23、the records, including those of the initial type testing, performed according to EN 295-2:2013, 5.2; and witnessing the audit tests performed according to Table 1 to Table 5. After passing the conformity assessment, the certification body can authorise the use of their identification symbol. 6 Audit

24、 testing Product requirements, test methods and the number of samples for audit testing are given in Table 1 to Table 5. Samples for testing are selected at random.
