PURPOSE OF THE PROJECT

The hardware and software complex is designed to conduct research and testing based on the physical and chemical analysis of the hazardous substances content in electrical and electronic products to confirm their compliance with requirements of Directives 2011/65/EU, 2015/863/EU, EAEU Technical Regulation 037/216, etc.

This complex allows determining acceptable levels of the following toxic substances content: lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6 +), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), 2-ethylhexyl phthalate (DEHP), butylbenzyl phthalate (BBP), dibutyl phthalate (DBP), diisobutyl phthalate (DIBP).

FEATURES OF THE PROJECT

The advanced European and global practice of the environmentally friendly product market development is inextricably linked with the regulation of acceptable levels of toxic substances (there are 10 of them at present: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers, 2-ethylhexyl phthalate, butylbenzyl phthalate, dibutyl phthalate, diisobutyl phthalate). One of the key factors for the access of products to the markets of the EU, North and South America, Southeast Asia and other regions, including the EAEC member countries is meeting the requirements for their contents.

In this regard, an expert and technical support in the product research as to the hazardous substances content is of crucial importance for the industrial sector of Belarus.

For these purposes, engineers of Theseus Lab s.r.o. developed and implemented a unique solution – the hardware and software complex for research and testing based on the physical and chemical analysis of the hazardous substances content in electrical and electronic products. Thus, the leading engineering center for product testing and certification in Belarus and EEU became the owner of the only complex in the Republic that allows determining the content of all regulated hazardous substances according to the EEU TR and the EU Directive with the necessary confidence.

The availability in Belarus of the modern multifunctional complex is important since it allows the laboratory to test and certify products not only nationally but also internationally, which results in the opportunity of Belarusian exporters to introduce their products to international markets.
