ROHS Compliance Test

Views:27     Author:Site Editor     Publish Time: 2019-03-26      Origin:Site Inquire

RoHS stands for the Restriction of Hazardous Substances. The RoHS Directive 2011/65/EU provides information concerning restrictions of the use of certain hazardous substances in electrical and electronic equipment. The cable experts in our industry-leading laboratory conduct RoHS Testing as part of our QA protocols as well as offering independent testing on third-party cables to determine compliance.



The Directive lists the following substances as being of a hazardous nature when used above the specified limits: 

 


SubstanceMaximum Concentration Values
Lead (Pb)<1000ppm
Mercury (Hg)<100ppm
Cadmium (Cd)<100ppm
Hexavalent Chromium (Cr VI)<1000ppm
Polybrominated Biphenyls (PBB)<1000ppm
Polybrominated Diphenyl Ethers (PBDE)   <1000ppm
Bis (2-ethylhexyl) Phthalate (DEHP)<1000ppm
Butyl Benzyl Phthalate (BBP)        <1000ppm
Dibutyl Phthalate (DBP)  <1000ppm
Diisobutyl Phthalate (DIBP)<1000ppm


RoHS testing is non-destructive as detailed in BS EN 62321-1:2013 and includes the use of X-Ray Fluorescent Spectrometry (BS EN 62321-3-1:2014).




A clean piece of cable approximately 200mm in length is placed on a wooden jig and the XRF analyser is placed in direct contact with the sample.


The XRF analyser bombards the cable material with X-Ray radiation which causes displacement of electrons in the atomic structure of the cable surface. As electrons fall back into the shells they emit or fluoresce energy. This energy can be measured and compared with the specific unique energies for each material type, allowing the determination of the presence of particular materials as well as their proportions within the material.


The RoHS test results are demonstrated by a Pass/ Fail criteria.

We are the only UK cable supplier to hold both the RoHS Trusted Kitemark and be accredited to UKAS ISO 17025 test methods for RoHS cable testing.
