5 General

Materials, products and fitness for purpose shall conform to the requirements given in EN 13598-1 and

EN 13598-2.

Materials and products shall be produced by the manufacturer under a quality management system

which includes a quality plan.
6 Testing (EN 13598-1)
6.1 Group
6.1.1 General

For the purposes of this document, the groups specified in 6.1.2 and 6.1.3 apply.

6.1.2 Size groups

For ancillary fittings the size groups are defined in Table 1 and for shallow chambers in Table 2.

The nominal diameter of ancillary fittings (excluding mechanical saddles) shall be that of the pipe which

can be connected to its outlet.

Mechanical saddles are sized by the nominal diameter of the main pipe that they are intended to joint to.

Each group shall consist of a range of products of the same material and design.
6.2 Type testing
6.2.1 General

Type testing is intended to demonstrate the ability of the product to fulfil the intended use and

characteristics detailed in the referring product standard.

Type testing shall be performed as described in Table 7 and Table 8 whenever there is:

a. a new system (N);
b. a change in design (D);
c. a change in material (M);
---------------------- Page: 12 ----------------------
SIST-TS CEN/TS 13598-3:2022
CEN/TS 13598-3:2021

d. a change in production processing method (P), other than routine in-process adjustments;

e. and an extension of the product range (E).

NOTE 1 Type testing may need to be revalidated as a result of deviation of process verification test (see 6.4).

— An example of a new system (N) would be understood as a manufacturer’s first application for a new

fitting group in accordance with EN 13598-1 or a change to more than one of the other categories.

— An example of a change in design (D) would be understood as changes that only have an influence on

the jointing and/or performance characteristics of the fittings.

— An example of a change in production processing method (P) would be understood as a change in

production method from e.g. injection moulding to rotational moulding.

— An example of an extension of the product range (E) would be understood as an extension with a new

size group.

For a change of material (M), Clauses 6.2.2 to 6.2.4 apply. A change of generic material (e.g. PP to PE) is

considered as a new system (N).

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 may be performed by the manufacturer or outsourced on behalf of the manufacturer.

NOTE 2 If certification is involved, the certification body may request the location of the test.

Type tests shall demonstrate that the products conform to all requirements for the characteristics given

in Tables 7 and 8, as applicable.
6.2.2 Change of material – PVC-U

Each formulation, including if applicable non-virgin material, shall be specified by the manufacturer in

the quality plan, including the ingredients and their tolerances.

If the dosage level in the formulation exceeds the tolerance band given in Table 4, or if there is a change

of type, this variation is considered to be a change in material.

In Table 4, for the virgin part of the formulation the values of the parts X added to 100 parts by mass of

PVC shall be specified by the manufacturer in the quality plan.

For the non-virgin part of the formulation (if applicable) the part X shall be given as a % of the mass of

the virgin part.

X7 shall not exceed the declared values as required in EN 13598-1:2020, Clause 5. This

means that a lower content of external reprocessed and/or recycled material in the

formulation which has already been type tested and which is fulfilling the agreed

specification is not considered as a material change.
6.2.3 Change of material - Polypropylene

Each compound, including if applicable non-virgin material, shall be specified by the manufacturer in the

quality plan, including the ingredients and their tolerances.

When a pigment masterbatch is used, it shall be considered as a change of compound if the type of

pigment carrier is changed.

If the content of the mineral modifier by mass is higher than the measured content by mass at type testing

or a new type of mineral modifier is used, this shall be considered as a change of material.

In Table 5,the values of the parts X shall add up to 100 % by mass (excluding own reprocessed material)

and be specified by the manufacturer in the quality plan.
