Sigma is ISO IEC 17025:2005 accredited ROHS Testing laboratory, equipped with sophisticated equipments like LC-ICPMS, GC-MSMS, spectroscopy to analyze and certify ROHS compliance testing in component materials through wet chemical screening, non-destructive analysis, XRF screening, and UV-vis. RoHS Compliance Testing has become standard procedure for most manufacturers, sellers, distributors and recyclers of electrical and electronic components or equipment sold or used in the European Union. The need for RoHS testing is a result of the Restriction of Hazardous Substances Directive or RoHS Directive, which became effective on July 1, 2006. The Directive was drawn up in the European Union to protect human health and the environment from hazardous substances by restricting the use of six hazardous chemicals in electrical and electronic products. We are equipped with ultra modern technology and sophisticated instruments like LC-ICPMS, GC-MSMS, spectroscopy that can determine the level of the following first four substances restricted by RoHS in component material:Mercury (Hg): 100ppmHexavalent Chromium (Cr(VI)): 1000 ppmCadmium (Cd): 100ppmPolybrominated Biphenyls (PBB): 1000 ppmLead (Pb) : 1000ppmPolybrominatedDiphenyl Ethers (PBDE): 1000 ppm RoHS has set maximum concentration values for each of these restricted substances. All values are set at 0.1%, except for cadmium with a limit of 0.01%. STRC has the capabilities to test for lead, mercury, cadmium and hexavalent chromium. RoHS compliance testing is performed in our lab using spectroscopy and wet chemistry methods to determine the concentrations of these RoHS substances in test samples. All RoHS testing results are fully documented in Certified Test Reports for our customers' records.

We provides soil testing services.Sigma analyses soil samples for ph, soil salts and nutrient levels in the soil for identifying its suitability for agriculture, presence of metals, organic matter, resistivity, crop nutrient requirements, fertilizer recommendations to get maximum productivity. Soil testing solutions offered help in testing overall health of the soil. Among many tests, one that is done includes testing of chloride content. Here, the negative effect of chloride concentration as present in soil on corrosion of reinforcing steel was done through measuring corrosion potentials as well as corrosion current density in soil testing. In the situation pertaining to presence of concrete in contact with soil can lead to corrosion of embedded reinforcement. Further, chloride levels in soils are also undertaken for checking of soil adjacent to concrete is suitable. The test method employed is meets is:4032-1985. Apart from this, other tests that are done for soil testing include:electrical resistivity it helps in determining if inferiorcheaper substance has electrical resistivity of soilthis is performed through testing soil physical properties like its structure, fluid composition and water contentit is also an attractive tool for describing subsurface properties without digging

Nabl accredited sigma offer various analytical testing services for drinking water, water for processed food, packaged drinking water, dialysis water, waste water, water for construction purpose, swimming pool water.Swimming pool water testingbacteriological condition: this test helps in determining the contamination by potentially harmful bacteria and other micro-organisms. Short term gastrointestinal disorders and illnesses such as gastro-enteritis, giardiasis, typhoid, dysentery, cholera, and hepatitis have been linked to water contaminated by microorganisms.Biochemical oxygen demand: this test helps in determining the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a specific time period. It is not a precise quantitative test, although it is widely used as an indication of the organic quality of water.Coliforms (total and faecal): this test helps in monitoring the increase or decrease of many pathogenic bacteriatotal plate count: the plate count method relies on bacteria growing a colony on a nutrient medium so that the colony becomes visible to the naked eye and the number of colonies on a plate can be counted.Streptococci (faecal): this test helps in determining the information about the source of contamination.Enterococci escherichia colilegionellapseudomonas aeruginosasuspended solidstotal greasedrinking water testingwater and fresh air are the unavoidable reasons for life. More than 70% of human body is composed by water. But unfortunately, only 3% of water available across the globe is fresh water and only half of that is available to humans. In developing countries like india, drinking water testing is essential because population growth combined with industrial development is hard pressing on water demand resulting in the shrinkage of water table.

NABL accredited Sigma offers independent toy testing facilities on physical parameters like fire resistance, heavy metal, toxic substances on plastic toys, crayons, paper toys, clays, complying with EN-71 testing standards to ensure safety and quality. BS EN 71: SAFETY OF TOYSThe safety of a child is an emotive subject, which is particularly close to the heart of every parent. When purchasing products for a child, product safety is an essential issue. Loose components, sharp edges, finger traps, the presence of toxic substances and materials which are too flammable can all result in serious harm to the child and severe consequences for the suppliers of any product deemed to be unsafe. Toys that are sold within the European Union are required to bear the CE mark. This is the manufacturer's declaration that the product meets the European Toy Safety Directive (2009 48EC), and has undergone a variety of product tests to ensure that it is safe for use. EN 71 is the European Standard for Toy Safety Testing. All the toys sold on the EU market need to comply with EN71 testing standards. EN 71 Part 1: Mechanical & Physical Properties of ToysThe purpose of this standard is to reduce risks associated with children's toys. Specific tests are performed on toys based upon the type of toy it is andor characteristics of the toy. EN 71 Part 2: Flammability of ToysThis portion determines the flammability of toys. It provides general requirements along with specific requirements for particular toys, which appear to be the most hazardous, this includes: toys to be worn on head, toy disguise costumes & intended to be worn by children in play, toys intended to be entered by a child, and soft filled toys. EN 71 Part 3: Migration of Certain ElementsThis part involves determining the migration of the following elements: Antimony, Barium, Cadmium, Chromium, Lead, Mercury, and Selenium from accessible parts of toys.
