QM 333 is the definitive quality standard set by the Telecommunication Engineering Centre (TEC) to ensure telecom equipment can withstand India’s diverse and often harsh climatic conditions. This testing suite simulates the entire lifespan of a product, verifying its structural integrity and functional reliability before it enters the Indian telecom network.

This standard applies broadly to any hardware intended for the telecom infrastructure. We cover:
Our testing scope covers the full spectrum of environmental stresses defined by TEC:
To ensure your test reports are valid for TEC certification, all testing is conducted in strict accordance with ISO/IEC 17025 requirements.
Timelines vary based on the specific "Category" of the equipment (Category A through D), as outdoor equipment requires longer exposure cycles.
Note: Damp Heat and Salt Mist cycles are time-fixed by the standard and cannot be rushed.
To initiate the project, the following physical deliverables are required:
Pricing is not fixed; it is calculated based on the complexity of the device and the testing category.
A smooth certification process relies on accurate documentation. Please prepare:
Yes, compliance with QM 333 is a mandatory prerequisite for obtaining TEC Type Approval or Interface Approval. It ensures your equipment meets the baseline durability requirements for the Indian network.
QM 333 is the general standard series, while QM 333:2010 is the latest active version. All current testing must strictly adhere to the 2010 specifications and severity levels.
TEC generally requires specific QM 333 testing. However, some IEC or ETSI reports may be accepted if the test parameters and severity levels match or exceed QM 333 requirements.
Yes, the equipment must be operational. We monitor performance parameters during climatic tests to ensure no degradation occurs under stress, proving the device's resilience in real-world scenarios.
If a failure occurs, we halt testing and provide a detailed failure analysis report. You can then rectify the design flaw and resubmit the unit for re-testing of the failed parameter.
Absolutely. Our labs are equipped with walk-in environmental chambers capable of accommodating large telecom racks, outdoor cabinets, and heavy base station equipment for full compliance testing.
The category is determined by the intended installation environment. Category A is for air-conditioned indoor use, while Category D covers unprotected outdoor environments. We assist in classifying your product correctly.
While QM 333 is specific to India, the testing is conducted in NABL-accredited labs using ISO 17025 standards. The results are technically robust and often accepted for internal quality verification globally.
