4.2.2 Grouping, for the purposes of this standard the following groups shall apply.
4.2.2.1 Size group
A group of nominal sizes DN. Three size groups are defined as given in Table 7.
Table 7 ― Definition of size groups
Size group number DN/OD or DN/ID
1 ≤ 200
2 > 200 and ≤ 500
3 > 500 and ≤ 1 200

4.2.2.2 Fitting group
A group of fitting types having a similar design. Three fitting groups are defined as follows:
 Fitting group 1: Bends;
 Fitting group 2: Branches;
 Fitting group 3: Other fittings.
Push-fit fittings and fusion fittings shall be considered separately for each group.

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,
Table 9 and Table 10 as applicable.
Type test shall be carried out on products manufactured using virgin material and in case reprocessable
and/or recyclable material according to Table 2, Table 4 or Table 6 is also intended to be used on products
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.
