List of Ex TL Labs in INDIA

Product Testing, Certification and the Nationally Recognized Testing Laboratories
The Measurement, Control & Automation Association believes that the current Product Approval Process is broken. Although the process control community supports international harmonization to IEC standards, we have elected not to target efforts to achieve that goal initially. Instead we believe that the US certification processes should be corrected first. To that end, we seek to harmonize the current conflicting patterns in the product testing and certification processes that increase costs, design uncertainty and time to market by establishing a unified third party testing and certification process:
where all testing is conducted in conformity with standards issued by the American National Standards Institute or, if standards are issued by another body (such as NFPA) where ANSI has recognized that standard specifically;
where certifications issued by an accredited testing laboratory are recognized by users, insurers and other testing laboratories through the use of a single, universal conformity mark but where individual testing laboratories can affix their own branded mark alongside;
where a product approved by one laboratory is accepted by all other NRTLs when appropriately combined with products which might have been tested and certified by a second laboratory; and
where follow-up NRTL manufacturing inspections are standardized to audit the quality process and are performed on an annual basis.
The Association has formed a Task Force of members who will actively pursue a remedy that will meet the above goals through OSHA and other means at our disposal.
Information about the NRTL program has been briefly outlined in a one-page document as well as a summary and scope of the current recognized laboratories which outlines their capability to test to the variety of standards applicable to products in our industry.
In 1999 and again in 2006 MCAA requested the following information from Nationally Recognized Testing Laboratories (NRTLs) which are among the 18 certified by the Department of Labor’s Occupational Health & Safety Administration (OSHA):
Capabilities to test/approve products (instruments/systems used in process control and factory automation to measure or control a variety of parameters such as weight, level, flow, temperature, physical or chemical properties including field measurement and centralized control systems) under standards for explosion proof (division 1 and 2), intrinsically safe and general-purpose design in both hazardous and non-hazardous locations.
The typical approval period from time of application through to certification for shipment.
All test locations capable of such test and approval and the most senior contact person at each such location responsible for the approval process.
Any additional information that would be useful to our members in obtaining timely testing and approval of their products.
The responses to our request are as summarized as follows. All listings have been updated in 2007. Scroll through all listings or click to read about a specific testing laboratory

3. Intertek Testing Services NA, Inc. (ITSNA)
Intertek can provide the approvals needed for global market entry and decrease time to market. Many valued clients have used the company for their domestic and international approvals, company ISO registrations and compliance to new ROHS regulations as well as functional safety requirements specified by customers. This simplified, efficient approach allows manufacturers to reduce cost, time and frustration associated with managing product compliance for global markets.
Intertek is accredited to assist manufacturers with approvals to US (ETL), Canadian (c-ETL), European (CE and EX) and International Standards through the IEC-EX scheme. They also offer InMetro Certification for Brazil, GOST-R for Russia and NOM approvals for Mexico.

They are an approved Certification Body for the CB Scheme for both Laboratory, Measurement and Control harmonized standards and Equipment for use in Potentially Explosive Atmospheres (IEC-Ex).
The approval process varies based on the complexity of the product. For ordinary locations, typical turnaround is three weeks based on manufacturer's readiness and compliance planning. For hazardous locations, Intertek can start a new project within two to six weeks from receipt of signed application and availability of samples and completed documentation package. The test program can last from one to four weeks depending on the number of products to be certified, intended markets, method of protection employed (flameproof, intrinsically safe, non-incendiary, etc.). For ATEX and IEC-Ex Certifications for Category 1 and 2 products, the manufacturer would also be required to obtain a Quality Audit Notification which can add time to the cycle, typically two weeks but expedited schedules may be available to meet aggressive shipment dates.
Intertek offers Design Review Services and Compliance Training to assist manufacturers in preparing for certification and avoiding common design pitfalls in the process of bringing new products to new markets. They partner with manufacturing clients in the design and prototype stages to help address critical issues that might delay certification and time to market.
