Many tests are conducted in the laboratories of Al-Jazeera Extensions Company for Industry to ensure that the products comply with quality standards:
- Raw material testing
- 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 Test is done to ensure that pipes are manufactured according to Saudi standard (14/151996) (675/1997) German Standard 8061 and American Standard ASTM D1785. Pressure varies depending on size and purpose of use.
(*) Impact test is subjecting pipes to a strikers weight, which is increased proportionately to pipe diameter.
