Verified batch test records and mechanical performance testing conducted at our in-house ISO 9001 certified laboratory in Jeddah.
Direct pricing from the Jeddah plant, with technical submittal support.
Every production run at ALFA AL-ARABIA's Jeddah plant is subjected to strict mechanical, thermal, and chemical laboratory testing conforming to ISO, DIN, ASTM, and Saudi Aramco standards.
Our central QA/QC testing facility in 3rd Industrial City, Jeddah, KSA operates calibrated digital metrology and testing apparatus calibrated annually against SASO national standards:
In compliance with EN 10204 Type 3.1, our quality inspection department operates independently of plant production, issuing certified test reports tied directly to specific batch numbers:
| Test Parameter | Governing Standard | Test Method & Condition | Mandated Pass Criterion | Sampling Frequency |
|---|---|---|---|---|
| Hydrostatic Burst Strength | ISO 1167 / ASTM D1599 | Pressurized water tank @ 20°C & 60°C | ≥ 3.8x nominal PN without rupture or weepage | Every production lot / 8 hrs |
| Vicat Softening Temperature | ISO 2507 / ASTM D1525 | Oil immersion under 50N load, 50°C/hr rise | ≥ 79°C (uPVC) / ≥ 103°C (CPVC) | Every resin lot |
| Dichloromethane Gelation | ISO 9852 | Methylene chloride immersion @ 15°C for 30m | Zero visual attack, delamination, or swelling | Per shift / extrusion line |
| Drop Impact Resistance | ISO 3127 / ASTM D2444 | Falling tup striker @ 0°C conditioned | TIR (True Impact Rate) ≤ 10% | Every production shift |
| Longitudinal Reversion | ISO 2505 | Circulating air oven @ 150°C for 60m | Dimensional change ≤ 5.0% without blisters | Daily per line |
| Density & Specific Gravity | ISO 1183 | Analytical immersion buoyancy balance | 1.40 - 1.46 g/cm³ (uPVC) / 1.50 - 1.58 (CPVC) | Per compound batch |
| Wall Thickness & Metrology | ISO 3126 / ASTM D2122 | Continuous ultrasonic 360° rotary gauge | 100% within tolerance; out-of-roundness < 1.5% | 100% continuous online |
| Heavy Metal Extraction | WHO / SASO ISO 1452 | Atomic absorption spectrophotometry (AAS) | Lead (Pb) < 0.01 mg/L, Cadmium < 0.003 mg/L | Quarterly independent lab |
Authentic technical answers covering hydrostatic testing, gelation tests, MTC Type 3.1 validation, and TPI inspections.
Conforming to EN 10204, a Type 3.1 Mill Test Certificate is an authenticated legal document issued by an authorized inspection representative independent of the manufacturing shop floor, certifying specific test results on the actual delivered batch.
Per ISO 9852, pipe rings are submerged in pure methylene chloride at 15°C for 30 minutes. If resin fusion (gelation) is incomplete, the solvent causes delamination and attack. Passing indicates full, homogenous polymer fusion.
Under ISO 1167 / ASTM D1599, pipe specimens are placed in a thermostatic water bath and pressurized continuously at a uniform rate until failure occurs (typically 60–70 seconds), requiring a burst pressure ≥ 3.8 to 4.2 times nominal working pressure.
Per ISO 2507, it measures the temperature at which a 1mm² flat-ended needle penetrates 1mm into the polymer under a 50N load. ALFA uPVC achieves ≥ 79°C and CPVC achieves ≥ 103°C, ensuring thermal stability under extreme Saudi desert heat.
Thermoplastics become more brittle at lower temperatures. Testing at 0°C (ISO 3127) represents worst-case handling conditions, proving that pipes withstand contractor rough handling and trench rock drops without cracking.
All laboratory pressure transducers, digital micrometers, thermal sensors, and scales are calibrated annually by SASO-accredited ISO/IEC 17025 metrology laboratories with full traceability certificates.
Yes. We regularly host consulting engineers, contractor QA managers, and Aramco Project Inspection Units (PIU) for formal Factory Acceptance Testing (FAT) witness hold points prior to batch delivery.
Per ISO 2505, pipe samples are heated to 150°C for 60 minutes. Excessive shrinkage (> 5%) indicates frozen-in molecular extrusion stress that could cause premature failure in the field. ALFA consistently tests at < 2.5%.
We submit production samples to certified third-party testing laboratories for heavy metal leachate analysis using Atomic Absorption Spectrophotometry, confirming lead levels below international drinking water detection limits.
Every bulk resin delivery from Sabic/Petrochemical majors is held in quarantine while our laboratory verifies K-value, bulk density, volatile matter, and particle size distribution before discharging into main silos.
We collaborate with SASO-accredited international inspection agencies including Bureau Veritas, SGS, TÜV, and Intertek for independent type testing and pre-shipment third-party inspections.
In accordance with ISO 9001 and Saudi Aramco SACS-002 cybersecurity requirements, all batch test data, calibration certificates, and MTCs are stored securely in digital archives for at least 10 years.
Under our ISO 9001 non-conformance protocol, the entire production lot produced since the last passing test is immediately quarantined, re-tested under secondary sampling, and scrapped if non-conformance is confirmed.
