19、eneral This document contains 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 suc

20、h as a certification scheme. 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,

21、 ZA.2, and EN 295-7:2013, ZA.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 ce

22、rtification body at least twice 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 E

23、N 295-2:2013, 5.3; checks of 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 i
