Quick Answer
Prism (NABL CC-2480) provides calibration for Gujarat's textile industry: yarn tensile testers (UTM), moisture meters, temperature instruments (dyeing machines, stenter frames), weighing systems, and colour measurement instruments — for ATIRA, Oeko-Tex, GOTS, and export buyer compliance.
Key Takeaways
- Yarn tensile and elongation testers require calibration per IS 1671 (ASTM D2256 equivalent).
- Textile processing temperature (dyeing, drying, stenter) calibration ensures colour consistency.
- Moisture content testing (grain moisture, textile moisture) requires calibrated instruments.
- Gujarat textile exports to EU/US require NABL-calibrated test instruments for buyer audits.
- ATIRA (Ahmedabad Textile Industry Research Association) recommends NABL calibration.
Textile Industry Instruments Calibrated at Prism
Yarn Tensile Tester
UTM calibration per IS 1671, ASTM D2256 for yarn tenacity, elongation, and breaking strength.
Dyeing Machine Temperature
Temperature sensors in dyeing machines (jet dyeing, jiggers, HTHP) — calibrated for colour recipe accuracy.
Stenter Frame Temperature
Thermocouple calibration in stenter frames for fabric drying and heat setting (140–200°C).
Weighing (Yarn Count)
Precision balances calibrated for yarn count determination (count box weighing).
Export Compliance Calibration for Textile Exporters
Surat is India's largest man-made fibre textile hub, exporting fabrics to 150+ countries. EU buyers (under REACH) and US buyers (CPSC regulations) require testing labs to be accredited and use calibrated instruments. Prism's NABL CC-2480 certificates carry ILAC MRA recognition, making test results from calibrated instruments acceptable to EU and US import auditors without retesting.
Frequently Asked Questions
Does Prism calibrate tensile testing machines used for fabric testing?
Yes. Prism calibrates tensile testing machines (UTMs) used for fabric tensile strength, tear strength, and seam strength testing per IS 1932, IS 6489, and ASTM D5035.
Can Prism calibrate instruments on-site at textile plants in Surat?
Yes. Prism's mobile calibration team provides on-site services at Surat's textile manufacturing clusters (Sachin GIDC, Pandesara GIDC, Surat city units).
Is NABL calibration required for GOTS (organic textile) certification?
GOTS certification auditors check that testing instruments in production are calibrated. While GOTS doesn't mandate NABL specifically, NABL calibration is the strongest evidence of instrument calibration reliability.
How often should dyeing machine temperature instruments be calibrated?
Annual calibration is standard. For colour-critical dyeing operations where temperature consistency is critical (reactive dyeing, acid dyeing on nylon), 6-month calibration of dyeing machine thermocouples is recommended.
Does Prism calibrate colour measurement spectrophotometers?
Yes. Prism calibrates reflectance spectrophotometers (Datacolor, X-Rite) used for textile colour measurement using NABL-calibrated reference colour tiles.
