Quality Policy
Various tests are conducted in Al Asad Laboratories to ensure that the products comply with quality standards:
- RAW MATERIAL TEST
- Gelation Time
- Bulk Density
- Sieve analysis
- Heat Stability
- FINAL PRODUCT TEST
- Pressure test (§)
- Impact Test (*)
- Chemical Resistance Test (Sulphuric Acid)
- Heat Reversion Test (Shrinkage)
- Water Absorption Test
- Resistance to environmental conditions
- (Extrusion) Methylene chloride test
- Tensile Strength test
- Elongation at break test
- HDT / VSP / Vcat test
- Opacity Test
Pressure tests are conducted to ensure that pipes are manufactured in accordance with Saudi standards (14/151996 and 675/1997), German Standard 8061, and American Standard ASTM D1785. The pressure applied varies depending on the size and intended use of the pipes.
An impact test involves subjecting pipes to a striker’s weight, which is increased proportionately to the pipe’s diameter.
