CEN/TS 1329-2:2026 is a CEN Technical Specification for assessing conformity of unplasticized poly(vinyl chloride) (PVC-U) piping systems for soil and waste discharge within buildings. It sets guidance and requirements for type testing, batch release testing, process verification testing and audit testing for formulations, products and assemblies covered by EN 1329-1:2026. Manufacturers use it to build a quality plan, and certification bodies use it to organize conformity assessment.
What does CEN/TS 1329-2:2026 specify?
CEN/TS 1329-2:2026 specifies how to assess conformity for PVC-U formulations, products and assemblies that follow EN 1329-1:2026. It links the testing scheme to the manufacturer’s quality plan and to certification procedures, so it matters both for routine production control and for third-party assessment.
The document is organized into:
- Scope
- Normative references
- Terms and definitions
- Abbreviated terms
- General requirements
- Testing, with subsections for grouping, type testing, batch release testing, process verification testing, audit testing and test records
- Annex A, an informative basic test matrix
| Annex | What it covers |
|---|---|
| Annex A | Basic test matrix for TT, BRT, PVT and AT |
The introduction also shows typical schemes for assessment of conformity with and without certification. That helps a manufacturer see where each test type sits in the overall control plan.
What are the key requirements of CEN/TS 1329-2:2026?
CEN/TS 1329-2:2026 requires the manufacturer to control materials and products through a quality management system with a quality plan, then apply different tests at different stages of production and surveillance. The practical point is that conformity is not checked once only - it is maintained through defined testing, sampling and records.
Quality system and grouping
Clause 5 says materials, products and fitness for purpose shall conform to EN 1329-1:2026. It also requires production under a quality management system that includes a quality plan, which means the manufacturer must define responsibilities, resources, test frequencies and actions for nonconforming products.
Clause 6.1 groups products for sampling. Pipes and fittings are divided into three size groups by nominal diameter, and fittings are also grouped as bends, branches and other fittings. This grouping matters because many test frequencies are set per size group, fitting group or cavity rather than for every single item.
Type testing
Clause 6.2.1 says type testing (TT) is needed when there is a new system, a design change, a material change, a change in production processing method for fittings, or an extension of the product range. If production site changes, the manufacturer decides which TT need revalidation. In practice, TT is the validation step for a changed or new product definition.
Clause 6.2.2 ties TT to the material specification. The formulation must define PVC-U resin, additives and dosage levels, and any reworked material or recyclate used in the product. If recyclates are used, TT must cover a 100 % virgin formulation and a second formulation with the maximum recyclate content; results at the maximum content can support products with lower recyclate content. That gives a clear rule for qualifying recycled content in the quality plan.
Batch release testing
Clause 6.3.1 requires incoming recyclate to be checked against the agreed specification for every recyclate batch. Clause 6.3.2 then uses batch release testing (BRT) to show that products can be released to market. Release is only allowed after the relevant tests and inspections are done at the required frequency and the requirements are met.
If a product fails, the batch is rejected or retested under the defined procedure that brackets the last conforming product and the first conforming product. That means the quality plan must define how to segregate affected production. The clause also allows indirect testing only when its correlation with the specified test is documented and regularly verified.
Process verification and audit testing
Clause 6.4 uses process verification testing (PVT) to confirm that the process remains stable and that previous TT results are still valid. The frequencies are periodic and become tighter when recyclates are used. If a PVT fails, the manufacturer must retest, investigate and correct the process, and check continued compliance with EN 1329-1:2026.
Clause 6.5 limits audit testing (AT) to cases where certification is involved. The certification body selects samples, preferably from products not previously chosen and from the largest production volume per sampling group. AT can be performed as a witness test if the certification body accepts it. In practice, AT is the independent check on both product conformity and the effectiveness of the quality management system.
Clause 6.6 requires test records to be kept for at least five years unless the quality management system says otherwise. This supports traceability during audits, complaints and certification reviews.
What terms does CEN/TS 1329-2:2026 define?
CEN/TS 1329-2:2026 defines the terms it uses for conformity assessment and sampling. The most important ones are:
- Certification body - a third-party body that operates certification schemes for conformity assessment.
- Laboratory - a body that performs testing, calibration or sampling linked to later testing or calibration.
- Quality management system - the part of a management system concerned with quality.
- Quality plan - the document that sets out quality practices, responsibilities, resources and the sequence of activities for a product range.
- Type test (TT) - a test that proves a formulation, product, joint or assembly can meet the relevant requirements or declared values.
- Batch release test (BRT) - a test done on a batch before it can be released.
- Process verification test (PVT) - a periodic test used to confirm that the originally performed TT remain valid.
- Audit test (AT) - a test performed on behalf of a certification body.
Who uses CEN/TS 1329-2:2026?
CEN/TS 1329-2:2026 is used by manufacturers of PVC-U pipes, fittings, joints and assemblies for building drainage systems. It is also used by quality managers and production engineers who must write the quality plan, set test frequencies, and decide what happens when a batch or process fails.
Testing laboratories use it to understand what to test, how often to sample and when indirect testing may be accepted. Certification bodies and inspection bodies use it to plan witness tests, audit tests and surveillance of conformity. Buyers, specifiers and project engineers use it to check whether a supplier’s conformity scheme matches the product requirements in EN 1329-1:2026.
What changed in CEN/TS 1329-2:2026 from the previous edition?
CEN/TS 1329-2:2026 supersedes CEN/TS 1329-2:2021. The foreword lists these main changes:
- alignment with the new template of AoC
- clarification in 6.2.2 that two TT are required if recyclates are used - one for the virgin formulation and one for the formulation with the maximum recyclate content
- addition of BRT for recyclates in 6.3.1
- specification of minimum sampling frequencies for BRT and PVT when recyclates are used in 6.3.2 and 6.4
Which standards are used with CEN/TS 1329-2:2026?
CEN/TS 1329-2:2026 is built around EN 1329-1:2026, which provides the product specifications for pipes, fittings and the system that the conformity assessment scheme checks. The document also points to several standards for bodies and systems involved in assessment:
- EN ISO/IEC 17065 - competence framework for product certification bodies
- EN ISO/IEC 17020 - competence framework for inspection bodies
- EN ISO/IEC 17025 - competence framework for testing and calibration laboratories
- EN ISO 9001 - requirements for quality management systems
- EN ISO 9000:2015 - quality management vocabulary used in the definitions
What does the CEN/TS 1329-2:2026 document contain?
CEN/TS 1329-2:2026 contains a conformity-assessment framework rather than product dimensions or installation instructions. It gives the test structure for TT, BRT, PVT and AT, with tables that assign each characteristic to a test type and sampling frequency for pipes, fittings and fitness for purpose.
It also contains the material-specification rules for PVC-U, additive dosage and recyclate use, plus the conditions that trigger re-testing when a design, material or process changes. Annex A gives the basic test matrix, and the main text includes the detailed procedures for release decisions, retest handling, indirect testing and record keeping.

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.
