24、general information on the concept of testing and organisation of those tests used for the purpose of the assessment of conformity. For each type of test, i.e. type testing (TT), batch release test (BRT), process verification test (PVT), and audit test (AT), this part of EN 13476 details the applica
25、ble characteristics to be assessed as well as the frequency and sampling of testing.

28、to be included in the manufacturers quality plan as part of the quality management system and for the establishment of third-party certification procedures. It is recommended that the quality management system conforms to or is no less stringent than the relevant requirements to EN ISO 9001:2008 1.
29、If third-party certification is involved, it is recommended that the certification body is accredited to EN 45011 2, EN 45012 3 or EN ISO/IEC 17021 4, as applicable.
