Introduction
This Technical Specification gives guidance for the assessment of conformity. It is intended to serve as a
guide for the assessment of conformity of products covered by EN 13476-1, EN 13476-2 and EN 13476-3.
It can be used integrally and/or be used for inclusion of conformity assessment in the manufacturer's quality
plan as part of the quality system for attestation purposes. The use of this Technical Specification does not
presume the involvement of a third party.
It can also be used to support the elaboration of national third party certification procedures for products
conforming to EN 13476-1, EN 13476-2 and EN 13476-3. It is the responsibility of the manufacturer to choose,
or not to choose for the involvement of a third party for certification purposes.

4.2.3 Type tests (TT)
4.2.3.1 General
Type tests shall demonstrate that products conform to all requirements for the characteristics given in Table 8,

manufactured using the maximum amount of reprocessable or recyclable material, which is intended to be
used unless the addition is in accordance with B.3, D.3 or F.3 of EN 13476-2:2007 and/or EN 13476-3:2007,
as applicable. In addition, relevant type tests shall be carried out whenever there is a change in design, in
compound including use of reprocessable or recyclable material, see, Table 8, Table 9 or Table 10 and/or in
the production method, other than routine in-process adjustments and to extensions of the product range as
indicated in the same tables.
In the case of change of compound or extended use of reprocessable or recyclable material the type testing
(TT) can be carried out by the manufacturer on the characteristics specified for such occasions in column M of
Table 8, Table 9 or and Table 10, as applicable. An audit test shall be made within 6 months to verify the
result of the TT.
