5 General
Materials, products and fitness for purpose shall conform to the requirements given in EN 1329-1:2026.
Materials and products shall be produced by the manufacturer under a quality management system
which includes a quality plan.
6 Testing
6.1 Grouping
For the purpose of this document, when applicable, the sampling groups specified below apply.
Three size groups are defined for pipes and fittings, as given in Table 1.

Fittings having a similar design are divided into three groups, as given in Table 2.
Table 2 — Fitting groups
Fitting group Type of fitting
1 Bends
2 Branches
3 Other fittings
NOTE Other fittings examples are given in
EN 1329-1.
6.2 Type testing
6.2.1 General
Type testing shall be performed as described in Table 3 to Table 5 whenever there is:
a. a new system (N);
b. a change in design (D);
c. a change of material (M) (see 6.2.2);
d. only for fittings: a change in production processing method (P), other than routine in-process
adjustments (see NOTE 1);
e. an extension of the product range (E), except the products already covered by the scheme of sampling
procedure.
NOTE 1: As an example, changing from fabricated fittings or rotomoulded fittings to injection moulding is a
change in production process. Temperature adjustment and dosing equipment exchange are not considered as a
change in production processing method.
When a change of production site occurs, the manufacturer shall determine which type tests need to be
revalidated.
Unless any of the conditions a) to e) above occurs, the type test results remain valid.
A type test can be performed as a witness test if accepted by the certification body.
