The positive impact of ROCHS rules on China’s scales industry

In order to control and reduce the environmental pollution caused by the waste of electronic information products and protect the environment and human health, as early as 2002, the EU issued the 2002/95/EC “Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment”, namely the ROHS Directive.

Since July 1, 2006, the new electrical and electronic equipment put on the EU market does not contain lead, mercury, cadmium, chromium, polybrominated biphenyls, polybrominated diphenyl ethers (PBDEs), or other hazardous substances.

The implementation of the ROCHS Directive has forced industrial enterprises in various countries to upgrade their industries to eliminate harmful substances and switch to the use of environmentally friendly materials.

Since March 1, 2007, China has required the control and reduction of environmental pollution caused by electronic information products during the production, sale, and import of electronic information products in China.

For the six hazardous substances, China’s Ministry of Information Industry provides specific determination methods.

China’s scale industry and the above-mentioned provisions of electronic components and related parts of the product-related materials are as follows:

PVC wire cable glands

Paint-containing lead, mercury Lead for soldering, lead-tin soldering of substrates, and electronic parts – containing lead.

Packaging materials (cartons, cushioning materials, PE bags, tapes) using paint
Ink – containing lead, cadmium, mercury, hexavalent chromium
Resistance of ceramic substrates
Piezoelectric devices – containing lead
Electrical contacts
Solder–contains cadmium
Electrical contact surface treatment – cadmium
Surface treatment (electroplating, chromate treatment) paint – cadmium
Various resins, rubber products with stabilizers – containing mercury
Anti-rust treatment (screws, steel plates)
Paint – containing hexavalent chromium.

The specific countermeasures of the scale production plant are, in the production or procurement of electronic information products (mainly refers to electronic components, circuit boards, batteries, wires and cables, and other electronic materials and computers and external equipment, measuring instruments, etc.) instructions should be filled in the name and content of toxic and hazardous substances

Should mark the environmental protection use period, and in the manual to explain the conditions of use and supporting parts of the special logo, the environmental protection use period

A recycling logo. It should be marked with a
Packaging materials should be marked on the packaging code (according to GB18455-2001 requirements)

At present, the ROHS rules are better implemented in China’s scale industry for products exported to Europe and America, or for some electronic information products purchased from domestic scale enterprises.

It is encouraging to note that some visionary scale sensor companies in China have introduced ROHS material analysis instruments in addition to applying for ROHS certification, which provides evidence to further confirm whether the procured materials are in compliance with ROHS measures and are worth promoting.
