Introduction
Figure 1 and Figure 2 are intended to provide general information on the concept of testing and organization
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 12201
details the applicable characteristics to be assessed as well as the frequency and sampling of testing.

6.1.4 Fitting types
Fitting groups are divided in fitting types.
Fitting group (A) includes the following fitting types: Electrofusion couplers, electrofusion 45° elbows,
electrofusion 90° elbows, electrofusion tees, electrofusion reducers, electrofusion end caps, etc.
Fitting group (B) includes the following fitting types: Electrofusion tapping saddles, electrofusion branch
saddles, etc.
Fitting group (C) includes the following fitting types: 45° elbows, 90° elbows, tees, reducers, end caps, etc.
Fitting group (D) includes the following fitting types: Swept bends, segmented bends, segmented tees, etc.
6.2 Type testing
Relevant TTs shall be carried out whenever there is a change in design, in compound or production method,
other than routine in-process adjustments, and/or whenever there is an extension of the product range or
change of production site.
Type tests, to be carried out when occurs a change of the production site, depend on the extent of the
change. Therefore, relevant type tests should be defined individually by the manufacturer.
Type tests shall demonstrate that the products conform to all requirements for the characteristics given in
Tables 3 to 6, as applicable.
In case of a change in compound as defined in A.2, relevant type testing requirements as defined in A.3, and
in Tables 3 to 6 as applicable, shall apply.
Effect on water quality shall only be considered for compounds and products intended for the conveyance of
water for human consumption.
For the purposes of a change in design, the following characteristics are relevant:
a) dimensions and geometry (see column D1 of Tables 5 and 6), as: change of visual and functional
optimisations, change of overall dimensions, change of a non-PE part;
b) joint affected part (see column D2 of Tables 5 and 6), as: change of the dimensions of the fusion zone
(e.g. wire pitch, wire depth), the electrical characteristics (e.g. wire, resistance), the fusion parameters
(e.g. time, voltage).
For the extension of the production range, the relevant characteristics given in Tables 4 to 6, column E, as
applicable, shall be retested. If certification is involved, retesting shall be agreed between the certification
body and the manufacturer.
For fabricated fittings, guidance for type testing is given in Annex B.
