Ozone test chamber for Hyundai automotive supplier Tamil Nadu India — Mobis India Limited, the Indian arm of Hyundai Mobis, placed Purchase Order P1903405889 with Ozone India Technology for an ozone test chamber and installation commissioning services worth ₹6,23,090. Mobis India Limited operates in Sriperumbudur, Tamil Nadu — in the same complex that houses Hyundai India's largest manufacturing plant. This blog explains why Hyundai's primary parts supplier in India invested in a premium ozone test chamber, what quality standards govern this testing, and what other automotive Tier-1 suppliers can learn from Mobis India's procurement approach.
Hyundai Mobis — The Backbone of Hyundai's Quality System
Hyundai Mobis is Hyundai Motor Group's primary parts and service division. Globally, Mobis supplies chassis systems, cockpit modules, front-end modules, and after-service parts to every Hyundai and Kia vehicle. In India, Mobis India Limited is Hyundai India's captive module supplier — delivering assembled chassis, cockpit, and lighting modules directly to the Sriperumbudur assembly line just-in-time.
The scale of Mobis India's operation at Sriperumbudur is significant: the company delivers chassis and module assemblies for Hyundai's 700,000+ annual unit production at the Tamil Nadu plant. Every rubber component in these modules — suspension bushings, body-mount rubbers, steering system seals, brake system rubbers — must carry ozone cracking resistance test data before installation into a Hyundai vehicle.
The ozone test chamber purchased from Ozone India Technology is assigned to Mobis India's Quality Control department, with User Department contact P.S. Mohanasivasankar confirmed in the purchase order. This confirms the chamber is a quality control instrument — not R&D — used for batch verification and supplier qualification of rubber components entering Mobis India's production line.
About the Mobis India Ozone Test Chamber Procurement
The PO (Reference P1903405889, dated 20-March-2019) placed by Mobis India Limited covers two line items:
Line 1: Installation and Commissioning Charges for Ozone Chamber — ₹10,000
Line 2: Ozone Test Chamber (set) — ₹6,13,090
Total: ₹6,23,090
The separation of installation/commissioning as a distinct line item (₹10,000) from the equipment value is characteristic of Korean/international automotive procurement — it allows the facility's capital expenditure (equipment) and operating expenditure (installation service) to be separately classified.
Price terms are "Total F.O.R. MIL Site" — meaning Ozone India Technology's price includes freight, unloading, and all charges to Mobis India's Sriperumbudur facility. Payment terms were 50% against proforma invoice, 50% against delivery — a balanced terms reflecting the established supplier relationship.
The ozone test chamber warranty period is one year after receipt, with a penalty clause of 0.1% per day on the order value (subject to 10% maximum) for delivery delay. This penalty structure is standard Hyundai Group procurement practice and reflects the impact that a missing quality instrument has on production scheduling.
What Mobis India Tests in the Ozone Test Chamber
The Quality Control department at Mobis India uses the ozone test chamber for:
Rubber Seal and Gasket Batch Approval
Every batch of rubber seals received from sub-suppliers undergoes ozone cracking resistance verification. The ozone test chamber exposes sample specimens at 50 pphm ozone, 40°C, 70% RH for the duration specified in Hyundai's material specification. Batches that fail are returned to the supplier without entry into production.
Chassis Bushing Compound Qualification
Suspension and steering bushings are safety-critical rubber components. Mobis India uses the ozone test chamber to qualify new rubber compounds submitted by bushing suppliers during PPAP. The compound must pass ozone exposure at Hyundai's specified conditions before first-sample approval.
Module Assembly Rubber Validation
Cockpit module and front-end module rubbers — grommets, grommets seals, anti-rattle pads, and vibration isolators — are validated in the ozone test chamber when new model variants or localisation substitutions are introduced.
Audit and Surveillance Testing
During Hyundai's annual quality system audit of Mobis India, auditors check the ozone test chamber calibration records, recent test logs, and test result trends. The audit confirms that the chamber is being used at the specified frequency and that all results are documented and acted upon.
Hyundai's Rubber Material Specifications and the Ozone Test Chamber
Hyundai Motor Group maintains a comprehensive set of material specifications (MS standards) that govern rubber compounds used in every system. The key MS standards that reference ozone test chamber testing:
- Hyundai MS-G-620: Rubber sealing material specification — ozone cracking resistance per ISO 1431-1 at 50 pphm / 40°C / 48 hours
- Hyundai MS-G-610: Rubber vibration isolator material — IS 3400 Part 20 or ISO 1431 ozone testing
- Hyundai STRESS (performance validation): System-level validation that includes rubber component ozone data
- IATF 16949 Control Plan: Ozone test frequency listed for all rubber parts on the control plan
Mobis India's ozone test chamber is sized and configured to run all of these test protocols. The chamber operates at the Hyundai-specified conditions, generates traceable data, and supports the PPAP documentation that Hyundai's quality engineers require before approving new material qualifications.

Sriperumbudur — India's Automotive Quality Capital
The Sriperumbudur-Irungattukottai-Oragadam triangle in Kancheepuram District, Tamil Nadu, is India's most concentrated automotive manufacturing location:
- Hyundai India — 700,000+ vehicles/year
- Kia India (Anantapur, nearby) — 300,000+ vehicles/year
- Renault-Nissan (Oragadam) — 250,000+ vehicles/year
- BMW India (Chennai) — premium segment
- Royal Enfield — motorcycles
- 400+ Tier-1 suppliers including Mobis India, INZI Controls, Samvardhana Motherson, Tenneco
Every one of these OEMs and Tier-1 suppliers has a quality laboratory. Not every lab has an in-house ozone test chamber — and those that do not rely on third-party laboratories. The in-house ozone test chamber at Mobis India gives the quality team same-day test results rather than waiting for external lab turnaround.
For the Sriperumbudur cluster, Ozone India Technology delivers ozone test chambers by road from Greater Noida — a 2,100 km route with transit time of 3–4 days by surface freight, or 1 day by express logistics. Installation and commissioning at Sriperumbudur is handled by Ozone India Technology's south India service team.

Why Mobis India Ltd. Chose Ozone India Technology
The ozone test chamber selection at Mobis India Limited was made by the Quality Control department, with authorisation from GP-Procurement (Vaisagvenibabu at gmobis.com). Several factors drove the decision:
Hyundai Group-Accepted Documentation: Ozone India Technology's CE Declaration of Conformity (CE-2621A), ISO 9001:2015 certificate (UQ-270426AD1), and factory test reports are accepted by Hyundai's quality auditors. This is the key differentiator — a chamber that generates unaccepted documentation is a compliance liability, not an asset.
F.O.R. Site Pricing: The total cost including freight, unloading, and all incidentals to the Sriperumbudur facility was included in the quoted price. Korean and international automotive companies prefer F.O.R. site pricing because it eliminates hidden logistics costs.
One-Year Warranty from Receipt: The warranty runs from the date of receipt, not the date of manufacture — a buyer-friendly term that Ozone India Technology's warranty policy supports.
Installation Commissioning as Separate PO Line: Ozone India Technology's ability to separately invoice the commissioning service (₹10,000) from the equipment value (₹6,13,090) aligned with Mobis India's capex/opex accounting structure.
Conclusion — Ozone Test Chamber for Hyundai's Premier Indian Supplier
Mobis India Limited's ₹6,23,090 investment in an ozone test chamber from Ozone India Technology reflects the quality infrastructure commitment of India's leading Korean automotive Tier-1 supplier. In-house ozone test chamber capability at the Sriperumbudur facility ensures that Hyundai India's assembly line is protected from rubber component failures, enabling the zero-defect supply chain that Hyundai's production schedule demands.
