In brief
TCR Engineering Services Pvt. Ltd. tests plastics, polymers, rubbers, composites and FRP/GRP at its Mahape laboratory in Navi Mumbai, India, which holds NABL ISO/IEC 17025:2017 certificate NABLT0726MH18640: tensile, flexural, compression, impact and hardness to ASTM D638, D790, D256 and D2240, with DSC, TGA and FTIR. These polymer methods are reported outside the accredited scope.
Testing of polymers, rubbers, and fibre-reinforced plastics for mechanical and environmental performance. Tensile, flexural, compression per ASTM D638, ASTM D790, ASTM D695. Izod impact on plastics per ASTM D256. Hardness (Shore A, D, IRHD) per ASTM D2240. Thermal properties: glass transition temperature, melting point, coefficient of thermal expansion, TGA, DSC. Environmental: accelerated weathering, UV resistance, heat ageing. FRP/GRP pipe qualification for hydrostatic performance, axial load, and cyclic pressure. ISO 527, ISO 178, ISO 179, ISO 180.
What does a polymer testing laboratory test?
A polymer testing laboratory measures how plastics, rubbers and fibre-reinforced composites carry load, resist heat and survive their service environment. At TCR Engineering that means tensile, flexural, compression and impact strength, Shore and IRHD hardness, glass transition and thermal stability, filler content, density and water absorption, all run in the Navi Mumbai materials testing laboratory.
Mica testing for EV battery thermal insulation was added in May 2026. Tile adhesive testing per IS 15477 (shear, pull-off, open time and slip tests) supports the construction-materials buyer.
Rubber and polymer characterisation also covers compression set and compressive strength on rubber, water absorption, filler content and identification, density and Fourier-transform infrared spectroscopy (FTIR).
The Navi Mumbai laboratory tests composites, plastics and rubber for quality, durability and performance.
Our services include:
- Tensile Testing: measures the strength and elongation of materials under tension.
- Shore Hardness Testing (Shore A & Shore D): Determines material hardness levels for both soft and rigid plastics.
- Differential Scanning Calorimetry (DSC): Analyses thermal properties and stability.
- Thermogravimetric Analysis (TGA): Measures changes in material weight as it is heated.
- Fourier Transform Infrared Spectroscopy (FTIR): Identifies chemical bonds in a material.
- Filler Content & Identification: Determines the percentage and type of filler in materials.
- Density Testing: Measures material density.
- Water Absorption Testing: Evaluates material's resistance to water.
- Compression Set & Compressive Strength Testing: Assesses rubber deformation and compressive strength.
Each result is reported against the governing standard listed below.
Standards: ASTM D638, D790, and D695 (tensile, flexural, compression), ASTM D256 (Izod impact), ASTM D785 and D2240 (hardness). ISO 527, ISO 178, ISO 179, ISO 180. IS 15477 (tile adhesive).

Frequently asked questions
What mechanical tests are available for plastics and composites?
Tensile, flexural and compression testing per ASTM D638, ASTM D790 and ASTM D695, Izod impact per ASTM D256, and hardness per ASTM D785 and ASTM D2240 including Shore A, Shore D and IRHD scales. Equivalent ISO methods 527, 178, 179 and 180 are also covered, with FRP/GRP pipe qualification for hydrostatic, axial and cyclic pressure performance.
Which thermal and chemical characterisation methods are offered?
Differential scanning calorimetry for thermal properties and glass transition, thermogravimetric analysis for weight change on heating, and FTIR for chemical bond identification. The laboratory also measures melting point, coefficient of thermal expansion, filler content and identification, density and water absorption, supporting quality control and material characterisation for demanding applications.
What environmental and rubber-specific tests are covered?
Accelerated weathering, UV resistance and heat ageing address environmental performance. Rubber characterisation covers compression set, compressive strength, Shore and IRHD hardness, density and water absorption. Tile adhesive testing per IS 15477 covers shear, pull-off, open time and slip, and FRP/GRP pipes are qualified for hydrostatic performance, axial load and cyclic pressure.
Are TCR's plastic and polymer tests NABL accredited?
No. The polymer mechanical, thermal and spectroscopic methods on this page, including ASTM D638, D790, D256, D2240, ISO 527, DSC, TGA and FTIR, are reported outside the scope of NABL certificate NABLT0726MH18640. RoHS testing of plastics, resins and rubbers to IEC 62321 is on that certificate and is covered on the RoHS page.
Which standards cover tensile and flexural testing of plastics?
Tensile properties of plastics are measured to ASTM D638 or ISO 527, flexural properties to ASTM D790 or ISO 178, compression to ASTM D695, and Izod impact to ASTM D256 or ISO 180. TCR reports each result against the standard the purchase specification names, for rigid plastics, rubbers and fibre-reinforced composites alike.
