RoHS (Restriction of Use of Hazardous Substances): An Overview

 RoHS (Restriction of Use of Hazardous Substances) regulations are designed to eliminate some of the particular chemical substances that can be dangerous to the environment and human health. Mercury (Hg), Lead (Pb), Cadmium (Cd), Hexavalent chromium (Hex-Cr), Polybrominated biphenyl (PBB) and Polybrominated diphenyl ether (PBDE) are the hazardous substances that are restricted in the manufacture of electronics and electronic devices, automatic dispensers, light bulbs, LED, household equipments, telecommunication equipments, toys and sports equipments . If appears, create environmental pollution and can be dangerous to the exposed manufacturer employees and recyclers. RoHS regulations were fully implemented in the Europe and UK in the year 2006.

RoHS Testing Labs

It is very important for the manufacturer to learn and to educate themselves about RoHS. Its testing should be carefully implemented as these hazardous chemical elements cause many serious ailments like different types of cancers. Hence, it is the responsibility of manufactures, importers, exporters and retailers for ensuring their products do not go beyond the maximum concentration limits. The maximum concentration limit for Cadmium is 0.01% generally found in semiconductors, PVC stabilizers, batteries, paints, dyes, solders and coatings. Lead, is often used in solders, termination coatings, PVC stabilizers, batteries, paints and pigments, Mercury generally used in sensors, batteries, fluorescent lamps and relays, Hexavalent Chromium often found in anti-corrosive coatings and in some of the plastics, Polybrominated biphenyls and Polybrominated diphenyl ethers are generally used as flame retardant are also have a maximum limit of 0.1%.

There are laboratories that offered RoHs testing. Handheld XRF analyzers are the portable devices that can be used for instant testing and documentation. Testing through these devices is fast, non-invasive and cost-effective. It also reduces the chances of human error.

WEEE (Waste from Electrical and Electronic Equipment) is a directive that controls the handling as well as recycling of electric and electronic equipments or devices.

Spectro Analytical Lab offers all the facilities such as AAS, XRF and ICP instruments for carrying out RoHS testing and it also provides training and assistance in this regard.

One More Feather in Our Cap: BIS for Safety Testing of Electrical & Electronic Products

BIS for Safety Testing of Electrical & Electronic Products
Electrical and Electronic Product Testing Labs

Spectro Analytical Labs Ltd., Greater Noida has successfully added another benchmark by achieving recognition through BIS in the field of Electrical and Electronic Testing for Safety Compliances of various Consumer Electronic Products like Audio, Video and similar Electronic Apparatus as well as Information Technology Equipments.

We will be now providing top class facilities to meet the compliance of ‘Electronics and Information Technology Goods Order 2012’ (Requirement for Compulsory Registration), mandating standards adopted by the Govt. of India.

CTOD Test: Another Extension in Our Scope

Crack-Tip Opening Displacement Test is carried out to test the Fracture toughness in order to check whether a material is fit for tough working conditions or not. It measures the deformation before undergoing failure in a pre-cracked sample. Spectro has developed skills to carry out CTOD test efficiently as per BS 7448 Standard.

It is practiced on those materials which undergo plastic (irreversible) deformation before it encounters failure. The testing material resembles the original one, but the dimensions can be reduced proportionally.

The crack tip opening can be calculated from the depth of the crack and opening at the mouth of the notch. Depending on the material used, the fracture can be brittle or ductile that can be concluded from the graph.

SEM: Another Triumph by Spectro

Spectro has added another advancement in its scope. We have procured the most sophisticated tabletop Scanning Electron Microscope; Hitachi TM3000, which has wide range of magnification i.e. 15x to 30,000x. SEM is employed for elemental analysis, identifying chemical and physical defects as well as the surface features. We have escalated a step further to test an immense array of Metals, Ceramics, Composite Materials, Glass, Fibers, Polymers, Electronic Materials and various other materials.
