- Throughput: the Mahape laboratory in Navi Mumbai handles more than 3,000 samples a month.
- Second facility: TCR Eastern at Bhubaneswar.
- Specimen preparation: a dedicated in-house machine shop prepares metallic and non-metallic specimens.
- Properties evaluated: tensile, compression, impact, weldability, fatigue and bend.
- Special service: elevated-temperature tensile testing, with proof stress determined by electronic extensometer.
- New block: heat treatment verification testing, built around the NADCAP AC7101 accreditation awarded in 2026.
TCR's mechanical testing service has a dedicated in-house machine shop that prepares metallic and non-metallic specimens for tensile, compression, impact, weldability, fatigue and bend testing.
Electronic extensometers give a precise determination of proof stress, and elevated-temperature tensile testing is a special service. Tests run to ASTM, BS, IS, DIN or client-specified standards.
Tensile tests establish the strength and characteristics of a material, with proof stress read by electronic extensometer. Elevated-temperature tensile tests run from 80 °C to 1,100 °C. Impact testing covers Izod and Charpy, at room temperature and at sub-zero temperatures down to -196 °C. TCR's Navi Mumbai laboratory also runs hydrostatic pressure tests on pipes.

Which accreditation should a metal testing laboratory hold, and how is a TCR report checked?
A metal testing laboratory should hold NABL ISO/IEC 17025:2017 accreditation for the methods it reports, and NADCAP AC7101 as well where parts enter the aerospace supply chain. TCR Engineering's Mahape laboratory in Navi Mumbai holds both, and every report it issues can be checked against the certificate, the published scope and the marks printed on the report itself.

Yes. TCR Engineering operates six creep frames to 1,100 °C at 50 kN with test durations to 100,000 hours in Navi Mumbai, including creep rupture of SUPER 304H (UNS S30432) boiler tube material per BHEL specification, IBR requirements, ASTM E139 and BS EN ISO 204.
Does TCR test for sour service (HIC and SSC) per NACE?
Yes. HIC and SSC testing per NACE TM0177 and TM0284 for sour hydrocarbon service is a core service of the materials testing pillar. TCR is PDO and OQGN approved for this work and has executed sour-service projects for Shell.
How many samples does TCR's laboratory handle each month?
The Mahape laboratory in Navi Mumbai handles 3,000+ samples per month across mechanical, chemical, corrosion, metallurgical and specialised methods, with samples received from 15+ countries and a dedicated in-house machine shop for specimen preparation. TCR Eastern at Bhubaneswar (NABL TC-15993) adds a second accredited facility.
Which accreditation should a metal testing laboratory hold, NABL or NADCAP?
Both, where the parts are for aerospace. NABL ISO/IEC 17025:2017 accreditation covers the method and the competence behind each result, and NADCAP AC7101 is the aerospace supply chain accreditation for materials testing.
