BS 3506:1969

What is BS 3506 – Specification for unplasticized PVC pipes for industrial use about? 

Unplasticized PVC pipes are rigid in structure that make for an excellent choice for industrial piping applications.

BS 3506 applies to unplasticized polyvinyl chloride (PVC) pipe up to and including 24 in nominal size, for industrial purposes. One series of thinner wall pipes and one of thicker wall pipes are included in addition to those covered by BS 3505.

Pipe complying with BS 3505 is deemed to comply with the requirements for corresponding classes in BS 3506.

Who is BS 3506 - Specification for unplasticized PVC pipes for industrial use for? 

BS 3506 on unplasticized PVC pipes is relevant to: 

• PVC pipe manufacturers and designers
• Entities involved in commissioning of PVC pipes
• Piping applications such as water distribution and fire-sprinkler systems

• Quality control and testing authorities
• Local bodies
• Contractors

Why should you use BS 3506 - Specification for unplasticized PVC pipes for industrial use?

For safe and reliable use in industrial applications, it is necessary that unplasticized PVC pipes conform to best industry practices and requirements, such that incidents of leakages and overall product failures are minimized.

In this regard, BS 3506 provides requirements for materials, dimensions, classification of pipes, physical and mechanical characteristics along with method of measuring dimensional characteristics.

The test methods in BS 3506 include:

• Heat reversion test
• Tensile test
• Short term and long term hydrostatic test
• Test for impact strength at 20 °C
• Test for resistance to acetone and supluric acid

Thus, compliance with BS 3506 can help demonstrate the quality, durability and performance of unplasticized PVC pipes for industrial use such that they are fit for use. Ultimately, you can ensure that your products are safe and reliable in operation and effective at the point of use.
