KiwaQuality certification evaluation guidelines
Plastics piping systems for industrial applications - monolayer piping systems of PB, PE, PE-RT, PE-X, PP, ABS, PVC-U, PVC-C and PVDF (KQ-17601)
KiwaQuality certification under Kiwa evaluation guideline KQ-17601 applies to products intended to be applied in plastics piping systems for the transport of chemical (hazardous) liquids and gaseous fluids, as well as of solid matter in fluids for industrial applications such as:
- chemical plants,
- industrial sewerage engineering,
- power engineering (cooling and general-purpose water supply),
- electroplating and pickling industry,
- the semiconductor industry,

The plastics piping systems are intended for underground as well as above ground applications. In the case of above ground applications, the piping systems might be directly exposed to sunlight.
For applications specially in the field of transport of gaseous and liquid fuels national (legal) requirements, e.g. standards, evaluation guidelines, national certification scheme’s, may be applicable.
This evaluation guideline specifies the characteristics and requirements for components such as pipes and fittings from one of the following materials:
- polybutene (PB),
- polyethylene (PE),
- polyethylene of raised temperature resistance (PE-RT),
- crosslinked polyethylene (PE-X),
- polypropylene (PP),
- acrylonitrile-butadiene-styrene (ABS),
- unplasticized polyvinyl chloride (PVC-U),
- chlorinated polyvinyl chloride (PVC-C),
- polyvinylidene fluoride (PVDF).
The requirements embodied in this evaluation guideline are applicable for plastics monolayer piping systems with welded and solvent cemented joints as well as mechanical connections.

- chemical plants,
- industrial sewerage engineering,
- power engineering (cooling and general-purpose water supply),
- electroplating and pickling industry,
- the semiconductor industry,
- water treatment.
The plastics piping systems are intended for underground as well as above ground applications. In the case of above ground applications, the piping systems might be directly exposed to sunlight.
For applications especially in the field of transport of gaseous and liquid fuels national (legal) requirements, e.g. standards, evaluation guidelines, national certification scheme’s, may be applicable.
This evaluation guideline specifies the characteristics and requirements for the following types of multilayer pipes: P-pipes, M-pipes and F-pipes.
The requirements embodied in this evaluation guideline are applicable for multilayer piping systems with welded and solvent cemented joints as well as mechanical connections. In case fittings are provided with rubber sealing elements, then these rubber sealing elements must be certified according to BRL KQ-17602.
The KQ 17603 evaluation guideline is a certification scheme for the KiwaQuality certificate for plastics piping systems for industrial applications - multilayer piping systems of PB, PE, PE-RT, PE-X, PP, ABS, PVC-U, PVC-C and PVDF.
