What is PVC testing?

Polyvinyl Chloride, also known as PVC, is a rigid plastic material that is used in many housing and building applications. Standard testing procedures by organizations such as ASTM and ISO are commonly used as guidelines for mechanical strength testing of PVC materials.

How do you test PVC plastic?

Just immerse a piece of the plastic in a glass containing a solution of 2 tablespoons of salt in 8 ounces of water. If it stays on the bottom it is PVC. If it floats it is ABS.

How are PVC pipes tested?

The most common test method is to use water under moderate pressure. However, installers sometimes opt for testing with air pressure because it is quicker and easier. But air testing, if done improperly, can be hazardous.

How can you distinguish plastic?

One of the simplest ways to carry out a flame test is by cutting a sample from the plastic and igniting it in a fume cupboard. The colour of flame, scent and characteristics of burning can give an indication of the type of plastic: Polyethylene (PE) – Drips, smells like candlewax.

What are the major reason for plastic testing?

Testing plays a critical role in the life cycle of a polymer, from the raw material to the compound through to the semi-finished and finished product.

What are the major reason for testing in plastic testing?

The physical and mechanical testing of polymers is a vital part of the product development and production process. Mechanical, thermal, optical, rheological behaviour and climate testing allow the developers to better understand their product, and introduce stronger quality control.

What is pipe testing?

The test specifies a method for determination of the resistance to constant internal pressure at constant temperature. The test samples are kept in an environment at a specific constant temperature, which can be either water (“water-in-water” test), another liquid (“water-in-liquid”) or air (“water-in-air” test).
