Overview

CEN/TS 1452-7:2014 provides guidance for the assessment of conformity of unplasticized poly(vinyl chloride) (PVC‑U) plastics piping systems used for water supply and for buried and above‑ground drainage and sewerage under pressure. Intended to be used together with EN ISO 1452 Parts 1–5, this Technical Specification explains how manufacturers, testing laboratories and certification bodies should organize testing, sampling and quality‑plan activities so that compounds/formulations, products, joints and assemblies meet the applicable standards.

Key topics and requirements

• Scope and applicability: Guidance applies to PVC‑U pipes, fittings, valves, joints and assemblies for pressurized water and sewerage systems (used in conjunction with EN ISO 1452‑1 to ‑5).
• Quality system linkage: Recommends inclusion of conformity assessment in the manufacturer’s quality plan and that the quality management system be no less stringent than EN ISO 9001.
• Testing structure: Defines the main test types used for conformity assessment:
  • Type tests (TTs) to demonstrate product capability.
  • Batch release tests (BRTs) required before batch release.
  • Process verification tests (PVTs) for ongoing process control.
  • Audit tests (ATs) performed by inspection or certification bodies.
  • Indirect tests (ITs) and witness tests (WTs) where applicable.
• Grouping and sampling: Advice on grouping by size, fittings/valves and other product families to optimize testing and sampling plans.
• Records and traceability: Requirements for maintaining test records, sampling plans and a basic test matrix (see Annex A).
• Conformity bodies: If certification is involved, bodies are preferably compliant with standards such as EN ISO/IEC 17065, EN ISO/IEC 17021, EN ISO/IEC 17025 or historical references EN 45011/45012 where applicable.

Practical applications and who uses it

• Manufacturers of PVC‑U pipes, fittings and valves - to build conformity rules into product quality plans and production control.
• Quality managers - for integrating EN ISO 1452 conformity activities into ISO 9001 systems.
• Testing laboratories - for planning type, batch and audit testing in line with TS guidance.
• Certification and inspection bodies - to structure certification procedures, audit tests and witness testing.
• Specifiers, procurement professionals and regulators - to understand expectations for factory testing, certification and documentation when accepting PVC‑U piping products.

Related standards

• EN ISO 1452‑1 to EN ISO 1452‑5 (PVC‑U piping system requirements)
• EN ISO 9001 (quality management)
• EN ISO/IEC 17025 (testing laboratories)
• EN ISO/IEC 17065 / EN ISO/IEC 17021 (certification/inspection bodies)
• Historical: EN 45011 / EN 45012 (where referenced)

CEN/TS 1452‑7:2014 is a practical conformity‑assessment guide enabling consistent testing, sampling and certification for PVC‑U piping systems used in pressurized water and sewerage applications.

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

Fitting group Type of fitting
1 Bends
2 Elbows, tees
3 Other fittings (reducers, double sockets, end caps,
adapters, etc.)
4 Valves
6.2 Type tests (TTs)
Relevant type tests shall be carried out whenever there is a change in design, in compound/formulation and/or
in the production method, other than routine in-process adjustments, and/or whenever there is an extension of
the product range or change of production site.
NOTE Testing to be performed in case of change of production site depends on the complexity of the changes and
therefore should be defined by the manufacturer case by case.
Type tests shall demonstrate that products conform to all requirements for the characteristics given in Table 5
to Table 7, as applicable.
The dosage level of ingredients of a compound/formulation shall not exceed the tolerance bands given in
Table 3. If any level exceeds the dosage band or if a type is changed, this variation constitutes a change in
compound/formulation.
The values of the parts X added to 100 parts by mass of PVC shall be specified by the manufacturer in his
quality plan.
Table 3 — Compound/formulation specification
Ingredients Characteristic/Type Band
PVC resin 100 parts K-value X1: ± 2
Stabilizers based on 1) Ca-Zn or
2) Sn or X2: ± 25 %
3) Others (OBS, Pb, etc.)
n
Total quantity of other CaCO , pigments,
x :±50%
additives lubricants, etc.
∑ i
If any level exceeds the dosage band or if a type of ingredient is changed, this variation constitutes a change
in compound/formulation and the relevant characteristics given in Table 5 to Table 7, column M, as applicable,
shall be retested. A change in the supplier of an ingredient or within a type of stabilizer does not necessarily
constitute a change in formulation. A change in the chemical nature of the stabilizer, e.g. from Pb to Sn, shall
constitute a change in compound/formulation (see EN ISO 1452-1:2009, 4.4.2 or 4.4.3 as applicable).
For the purpose of defining a change in design, the following aspects are relevant:
a) functional dimensions;
b) geometry of the functional parts of the product;
c) joint affected parts.
If one or more of these characteristics exceed the defined specifications, the relevant characteristics given in
Table 4 to Table 7, column D, as applicable, shall be retested. If third party certification is involved, retesting
shall be agreed between the certification body and the manufacturer.
For the extension of the production range, the relevant characteristics given in Table 5 to Table 7, column E,
as applicable, shall be retested. If third party certification is involved, retesting shall be agreed between the
certification body and the manufacturer.
Table 4 is applicable if the compound/formulation is produced by the raw material manufacturer and not by the
pipe, fitting or valve manufacturer.
