b) Initial inspection of the factory and of factory production control;
c) Continuous surveillance and assessment of the factory production control.
2) Initial type testing of the product;
NOTE There may be a need to involve a third party, with 1b, 1c, and/or 2, for the purpose of regulatory marking (see Annex
ZA).
5.2 Initial type testing of the product (see 5.1, 2)
5.2.1 General
All the product’s characteristics shall be initial type tested to verify they are in conformity with the requirements of
this document. In addition instead of performing any actual testing, initial type testing may make use of:
 generally accepted and/or conventional and/or standardised values, in the Clause 2 referenced standards, or
in publications that are referred to in these standards;
 standardised calculation methods and recognised calculation methods in Clause 2 referenced standards, or in
publications that are referred to in these standards;
 test report(s) on the basis of 5.2.1.2 when made available except for the characteristics listed in 5.2.2.
 where components are used whose characteristics have already been determined, by the component
manufacturer, on the basis of conformity with other product standards, these characteristics need not be
reassessed providing they remain unchanged by the manufacturing process;
11

---------------------- Page: 12 ----------------------
prEN 15683-2:2007 (E)
 release of dangerous substances may be assessed indirectly by controlling the content of the substance
concerned;
 durability may be assessed indirectly by controlling the production processes according to this document;
NOTE 1: Products CE marked in accordance with appropriate harmonised European specifications may be presumed to have
the performances stated with the CE marking.
NOTE 2: There may be a need to involve a third party for the purpose of regulatory marking (see Annex ZA).
When actual testing is required then the Initial Type Testing (ITT) shall be undertaken on a sample representative
of the product taken from direct production or a prototype, any plant and/ or line.
Whenever a change occurs in the raw material or the production process (subject to the definition of the family),
which would change significantly one or more of the characteristics, the type tests shall be repeated for the
appropriate characteristics.
5.2.1.1 Multiple lines/sites
If a manufacturer operates one and/or more lines and/or sites, the following can reduce the requirement for multiple
Initial Type Testing (ITT):
i) The manufacturers’ technical file for a product shall specifically covers all sites and/or lines of the
