Ozone test chamber for NABL accredited testing laboratory is a highly specific procurement category — and Kanha Testing Labs Pvt. Ltd. in Gurgaon, Haryana, is exactly the customer that represents it. Kanha Testing Labs, a NABL (National Accreditation Board for Testing and Calibration Laboratories) accredited facility in Gurgaon, Haryana, ordered a precision ozone test chamber from Ozone India Technology for their analytical services. A NABL-accredited lab has stricter equipment requirements than any industrial QC laboratory — because the test data they generate becomes the official quality certification relied upon by manufacturers, regulators, and courts. This blog explains how Kanha Testing Labs selected their ozone test chamber, what NABL requirements the equipment must meet, and why Gurgaon's testing laboratory market is among the most demanding in India.
NABL Accreditation and the Ozone Test Chamber
NABL (National Accreditation Board for Testing and Calibration Laboratories) is India's national accreditation body, operating under the Department for Promotion of Industry and Internal Trade (DPIIT), Government of India. NABL accreditation is based on ISO/IEC 17025:2017 — the international standard for testing and calibration laboratories.
For a laboratory to offer ozone cracking resistance testing under NABL scope, the ozone test chamber used must meet these requirements:
- Calibration traceability: Ozone concentration calibration must be traceable to national or international measurement standards (National Physical Laboratory of India, NPL)
- Measurement uncertainty: The laboratory must quantify and document measurement uncertainty for all parameters — ozone concentration, temperature, humidity, time
- Equipment record: The ozone test chamber must be listed in the equipment register with make, model, serial number, and calibration frequency
- Preventive maintenance: A documented PM schedule must be maintained for the ozone generator cell, compressor, refrigeration system, and ozone sensor
- Environmental control: The room in which the ozone test chamber operates must itself be temperature and humidity controlled
Kanha Testing Labs (CIN: U93000HR2013PTC048202) operates to NABL's rigorous requirements. Their ozone test chamber order specified a chamber size of 500L × 450B × 500H mm with ozone concentration range 1–500 PPHM — a wider range than many industrial chambers — and concentration stability ±5–7%.
About Kanha Testing Labs Pvt. Ltd.
Kanha Testing Labs Pvt. Ltd. operates in Gurgaon, Haryana. The company is NABL accredited — a designation they display prominently on their letterhead as "NABL ACCREDITATED" [sic]. Their CIN U93000HR2013PTC048202 confirms incorporation in Haryana in 2013.
The purchase order for the ozone test chamber was prepared by Avinash and authorised by the company director. Delivery was specified within 40 days, with freight and packing included and installation and training charges also included — a comprehensive supply package that NABL-accredited labs require to meet ISO/IEC 17025 equipment qualification protocols.
The technical specification shows a carefully designed requirement:
| Parameter | Kanha Testing Labs Specification |
|---|---|
| Cabinet | Mild Steel Powder Coated |
| Inner Side | SS-304 |
| Chamber Size | 500L × 450B × 500H mm |
| Ozone Concentration | 1–500 PPHM (as per customised need) |
| Concentration Stability | ±5–7% (whichever greater) |
| Display | 3½ Digit LED, 12mm high |
| Sensor | Electrochemical type |
| Ozone Generator | Included |
| Temperature | 15°C to 50°C (±5–7% of set point) |
| Humidity | 30–70% RH (±5–7% of set point) |
| Timer | Select 55xc (1 second to 10 hours) |
| Accessories | Sample Holder Fixture included |
The 1 PPHM lower limit of the ozone concentration range is notably lower than most industrial specifications (which start at 25–50 PPHM). This reflects Kanha Testing Labs' need to characterise compounds at very low ozone concentrations — relevant for outdoor ambient exposure modelling and long-term durability studies.
ISO/IEC 17025 Requirements for Ozone Test Chamber Equipment
A NABL-accredited lab must meet ISO/IEC 17025:2017 requirements for equipment — requirements that go beyond what IATF 16949-certified industrial labs typically enforce. For the ozone test chamber specifically:
Clause 6.4.3 — Equipment: The laboratory must have procedures for handling, transporting, storing, and using equipment to prevent contamination or deterioration. The ozone test chamber's SS-304 inner construction is an ISO/IEC 17025 requirement because mild steel would corrode under ozone atmosphere, introducing measurement uncertainty.
Clause 6.4.4 — Equipment records: Each ozone test chamber must have a complete equipment record including: equipment name and unique identifier, manufacturer name, model and serial number, date of receipt and entry into service, current condition, calibration date and results, maintenance history, and any damage or malfunction.
Clause 6.4.6 — Calibration: All equipment that affects the validity of results must be calibrated before use. For the ozone test chamber, this means ozone concentration calibration (typically annual), temperature calibration (annual), and humidity calibration (annual) — all traceable to NPL standards.
Ozone India Technology provides all calibration certificates with the ozone test chamber delivery, formatted to support ISO/IEC 17025 equipment records. The electrochemical ozone sensor, temperature sensor, and humidity sensor are individually calibrated and certificated.
The Testing Services Kanha Testing Labs Offers with the Ozone Test Chamber
Once commissioned, the ozone test chamber at Kanha Testing Labs enables these NABL-scope testing services:
Ozone Cracking Resistance Testing (IS 3400 Part 20 / ISO 1431-1)
The primary service — rubber specimen exposure at defined ozone concentration, temperature, and duration. Results are reported as "pass" or "fail" based on visual inspection for ozone cracks.
Material Qualification Testing for Automotive Suppliers
Tier-1 and Tier-2 automotive suppliers in Gurgaon who lack in-house ozone test chambers send specimens to Kanha Testing Labs for PPAP-supporting material test data.
Incoming Quality Inspection for Rubber Buyers
Procurement teams at companies buying rubber seals, gaskets, and polymer mouldings use Kanha Testing Labs' ozone test chamber data to verify supplier claims before acceptance.
Research and Development Support
Rubber compound formulators use the ozone test chamber to screen experimental formulations — comparing antiozonant types, concentrations, and carrier systems.
Third-Party Dispute Resolution
When a rubber component fails in service and the cause is disputed, NABL-certified ozone test chamber data from Kanha Testing Labs provides the independent, legally recognised evidence required for insurance or warranty claims.
