NABL Laboratory Accreditation & Metallurgical Testing Infrastructure
BTPS operates an in-house NABL-accredited metallurgical and hydrostatic testing laboratory at our 1,000,000 annual capacity facility in Belagavi, Karnataka, delivering certified chemical, mechanical, and pressure test reports under ISO/IEC 17025:2017 standards.
Accredited Metallurgical & Pressure Testing Protocols
Our NABL-certified laboratory performs rigorous chemical analysis, destructive mechanical testing, and volumetric expansion verification for all cylinder production batches.
Chemical Spectrophotometry & Steel Grade Analysis
Optical Emission Spectrometry (OES) verifies carbon, manganese, sulfur, and phosphorus concentrations in JSW prime steel coils (IS 6240 / IS 15914) to prevent raw material inclusions.
Universal Mechanical Tensile & Weld Joint Audits
Universal Testing Machines (UTM) perform destructive yield, ultimate tensile strength (UTS), elongation, and flattened weld seam bend tests on heat-treated shell samples.
Calcium Silicate Porous Mass & Porosity Audits
Destructive core extraction testing verifies that monolithic calcium silicate porous mass achieves precise 90%–92% porosity and ≥22 kgf/cm² compressive crushing strength for IS 7312 DA cylinders.
National Calibration Traceability & BIS / PESO Oversight
All laboratory gauges, pressure transducers, and test rigs maintain unbroken national calibration traceability for statutory PESO inspection sign-offs.
250 kgf/cm² Digital Pressure Gauge Calibration
Master pressure transducers and digital gauges operating up to 250 kgf/cm² undergo periodic NABL recalibration to guarantee ±0.5% accuracy during hydrostatic water-jacket testing.
NABL Accredited Test Reports & PESO Clearances
Commercial batch shipments receive formal NABL test certificates, TÜV SÜD ISO 9001:2015 audit reports (Cert #99 100 23469), and PESO inspector approval logs prior to factory dispatch.
NABL Laboratory Accreditation Guidelines
What specific scope of accreditation does the BTPS NABL testing laboratory hold?
The BTPS in-house laboratory operates under NABL accreditation per ISO/IEC 17025:2017, covering chemical composition spectrometry of IS 6240/15914 steel, mechanical tensile/flattening tests, hydrostatic volumetric expansion calibration (up to 250 kgf/cm²), and porous mass density audits per IS 7312.
How does NABL laboratory accreditation benefit enterprise B2B cylinder procurement?
NABL accreditation ensures that all batch test certificates issued by BTPS carry international equivalence, eliminating the need for redundant third-party re-testing while fulfilling mandatory statutory requirements for PESO and BIS approvals.
Are NABL-stamped test reports provided with every commercial cylinder shipment?
Yes, every batch order dispatched from our Belagavi plant is accompanied by an official NABL-accredited laboratory test report detailing heat-number chemical analyses, tensile strength metrics, hydrostatic permanent expansion values, and porous mass porosity figures.
