In the EU Directive 2015/863, the RoHS standard (Restriction of Hazardous Substances) has found its third supplement. HBM assures full compatibility with RoHS 3 for affected strain gauge accessories, such as bonding materials or protective coatings.
Restriction of Hazardous Substances (RoHS) is an EU directive that limits the use of certain hazardous materials found in electronic or mechanical components. Sensor and transducer suppliers must cooperate with RoHS specifications for products to be made available on EU markets. These specifications have changed over the years with new and emerging materials requiring restriction for use in commercial applications. The original six substances that were controlled and restricted by RoHS were:
- Cadmium (Cd);
- Hexavalent Chromium (Cr VI);
- Lead (Pb);
- Mercury (Hg);
- Polybrominated Biphenyls (PBB);
- Polybrominated Diphenyl Ethers (PBDE).
Sensor and transducer suppliers that utilize these substances in the manufacture of mechanical or electronic components must ensure that their levels remain below 1000 ppm of the homogenous material in the product. This excludes mercury and lead, which are controlled at more stringent levels of below 100 ppm.
RoHS 3 is an addition to the directive, adding four more restricted substances for sensor and transducer suppliers to limit in component applications:
- Bis(2-Ethylhexyl) phthalate (DEHP);
- Benzyl butyl phthalate (BBP);
- Dibutyl phthalate (DBP);
- Diisobutyl phthalate (DIBP);
Each of these plasticizers was added to the directive in 2015. They are subject to a grace period, to allow sensor and transducer suppliers time to comply with the new regulation. All EU monitoring and control equipment must keep component quantities of the above substances below 1000 ppm by 2021 to comply with RoHS 3.
HBM is a leading sensor and transducer supplier, with a global supply network of test and control equipment for a broad range of test bench applications. We provide a range of instrumentation for global markets, and are committed to complying with all certifications to ensure that all our products meet the highest possible safety standards.
Unlike many other sensor and transducer suppliers, our entire range of strain gauges, covering agents, and bonding materials already comply with RoHS 3. Below is the full list of HBM products that fall under RoHS 3 specification, and meet its requirements well before the closing of the grace period:
The only exceptions to these compliances are customer specific variants for bespoke applications, or uncommon circumstances when lead-based solder was required for the manufacturing process.
HBM is committed to complying with future certifications today. For more information from sensor and transducer suppliers that are prepared for tomorrow’s regulations, please do not hesitate to contact us.
