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.

assemblies in accordance with the applicable part(s) of EN 12201 intended to be included in the

manufacturer’s quality plan as part of the quality management system and for the establishment of certification

procedures.

It is recommended that the quality management system conforms to or is no less stringent than the relevant

requirements to EN ISO 9001 [1].

NOTE 1 If certification is involved, the certification and inspection body is preferably compliant with

EN ISO/IEC 17065 [5], EN ISO/IEC 17021 [3] or EN ISO/IEC 17020 [2], as applicable.

In conjunction with Parts 1 to 5 of EN 12201 (see Foreword) this document is applicable to polyethylene (PE)

plastics piping systems for water supply, and for drainage and sewerage under pressure. It is applicable to PE

pipes, fittings, and valves, their joints and to joints with components of other materials intended to be used

under the following conditions:
a) allowable operating pressure, PFA, up to 25 bar
b) an operating temperature of 20 °C as a reference temperature;
c) buried in the ground;
d) sea outfalls;
e) laid in water;
f) above ground, including pipes suspended below bridges.

NOTE 2 For applications operating at constant temperature greater than 20 °C and up to 40 °C, see EN 12201-1:2011,

Annex A.

NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects,

taking into account their particular requirements and any relevant national guidance or regulations and installation

practices or codes.

5 General

5.1 Compounds, products, joints and assemblies shall conform to the requirements given in

EN 12201-1:2011, EN 12201-2:2011+A1:2013, EN 12201-3:2011+A1:2012, EN 12201-4:2012, and

EN 12201-5:2011.

NOTE For socket fusion fittings according to EN 12201–3+A1:2012, Annex A, assessment of conformity may be

agreed between the manufacturer and the end user.

5.2 Compounds, products and assemblies shall be produced by the manufacturer under a quality

management system, which includes a quality plan.

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.
