Petrochemicals Testing

Petrochemicals Testing

REACH Testing Services

We offer physico- chemical, toxicological, environmental fate, Eco- toxicological and residues testing and analysis services to help your business successfully navigate the complex REACH testing requirements.
REACH requires manufacturers and importers to gather information on the properties of their chemical substances. This will enable safe handling and registration of chemical information in a central database managed by the European Chemicals Agency (ECHA). Submission of data on chemical properties, in the form of a dossier, that is a mandatory part of the REACH Registration process. Gaps in information to complete a dossier may require REACH laboratory testing.

REACH Certificate Services

STRC is a leading international provider of REACH certificate services, with a proven track record in providing testing data for regulatory submissions and chemical registrations for a wide range of industries. We offer manufacturers, importers and users of chemicals cost-effective testing for REACH compliance.

RoHS Testing Services

RoHS Testing Services

The company has complete in-house facility to execute various jobs related to RoHS. STRC offers RoHS testing services for restricted substances in electrical equipment and electronic products.
RoHS is often referred to as the lead-free directive, but it restricts the use of the following six substances:

  • Lead
  • Mercury
  • Cadmium
  • Hexavalent chromium (chromium xxx or Cr6+)
  • Polybrominated biphenyls (PBB)
  • Polybrominated diphenyl ether (PBDE)

PBB and PBDE are flame retardants used in several plastics.


The maximum concentrations are 0.1% or 1000 ppm (except for cadmium, which is limited to 0.01% or 100 ppm) by weight of homogeneous material. This means that the limits do not apply to the weight of the finished product, or even to a component, but to any single substance that can (theoretically) be separated mechanically – for example, the sheath on a cable or the tinning on a component lead.

RoHS Testing Services

STRC provides RoHS compliance product and material testing services which include standard testing for the EU RoHS Directive requirements.

STRC’s RoHS testing methods include: ICP-MS, ICP-OES, GC-MS, GC-ECD, FTIR, UV-vis, and other RoHS testing methods.

Oils Testing and Analysis Services (Essential Oils)

STRC has complete in-house facility to execute various jobs related to wide range of oils. The types of oils tested include crude oil, lubricants, vegetable and animal oils, essential oils, synthetic oils and much more. The testing is carried out as per recognized industrial standards such as ASTM, IP and AOAC.

Why is Essential Oil Testing Important and what are the Standards?

In India, the labelling of essential oils as therapeutic is up to the manufacturer as there are no labelling regulations or standards for essential oils. Any oil whether adulterated or not, can say on the label that the oils are 100% pure and therapeutic. A good way to be certain that you are purchasing a therapeutic grade essential oil is to purchase ISO certified products.

Oil products tested include :

  • Oil chemical analysis
  • Oil physical property testing
  • Oil quality
  • Oil purity
  • Oil characteristics
  • Oil composition
  • Oil assay
  • Oil contamination
  • Oil impurities
  • Toxicology

We offer the following physical and chemical tests:

  • Relative Density
  • Refractive Index
  • Optical Rotation
  • Solubility
  • Component Analysis by Gas Chromatography
