LISUN solution for RoHS testing methods

Introduction to RoHS testing
The European Union officially announced the 2002/95/EC Directive on 27th January, 2003, the "Directive on the Prohibition of Certain Hazardous Substances in Electrical and Electronic Equipment" (referred to as the RoHS Directive), which took effect on 1st July, 2006 . The directive requires that eight categories of electronic and electrical products sold in the EU market must undergo RoHS testing and must not contain six hazardous substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers.

ROSH Environmental Certification-Management Measures for the Control of Pollution by Electronic Information Products-The "Administrative Measures" implemented on 1st March, 2007 require companies to affix their labels in accordance with the requirements of SJ/T 11364-2006.

Core content of "Administrative Measures":
Producers should gradually reduce and eliminate the content of lead, mercury, cadmium, hexavalent chromium, polymeric brominated biphenyl (PBB), polymeric brominated biphenyl (PBDE) and other toxic and hazardous substances in products; for those that cannot be completely eliminated, The content of toxic and hazardous substances shall not exceed the relevant provisions of the standard.


The detection methods of 6 hazardous substances in RoHS:


“Testing Methods for Toxic and Harmful Substances in Electronic Information Products" (hereinafter referred to as "Testing Methods", the standard number is SJ/T 11365-2006) limits the testing methods for harmful elements in the RoHS requirements. Among them, X-ray fluorescence spectroscopy (XRF) has been established as a quick screening method as the fastest and most convenient method. X-ray fluorescence spectroscopy (XRF) can be used to accurately test the corresponding standard samples of the five elements of lead (Pb), mercury (Hg), cadmium (Cd), chromium (Cr), and bromine (Br).


The EDX-2 RoHS test Instrument mentioned in the above detection method is a RoHS edxrf spectrometer developed by Lisun engineers according to market demand, which fully meets the requirements of the latest EU RoHS directive and is exported to foreign markets. The following is the product picture:

Common Test Methods for RoHS Test Equipment

RoHS is a mandatory standard established by EU legislation. Its full name is "Restriction of Hazardous Substances" (Restriction of Hazardous Substances). This standard has been formally implemented since July 1, 2006 which is mainly used to regulate the materials and process standards of electrical and electronic products. And making it more conducive to human health and environmental protection. The ROHS directive is divided into RoHS1.0 and RoHS2.0, and the substances required to be tested are different, and the test methods are also different.

There are many RoHS test methods: Chemical detection, X-ray fluorescence spectrometry (XRF), Gas chromatography/mass spectrometry (GC-MS), etc. Among them, X-ray fluorescence spectroscopy (XRF) has been established as a quick screening method as the fastest and most convenient method. X-ray fluorescence spectroscopy (XRF) can be used to accurately test the corresponding standard samples of the five elements of lead (Pb), mercury (Hg), cadmium (Cd), chromium (Cr), and bromine (Br). If the sample composition is uneven, it is invalid. (These five substances are controlled by the ROHS1.0 directive)

LISUN EDX-2 RoHS detective testing equipment (Analyzer for rohs compliance testing) use the XRF method, it with below advantages and features:

High-resolution, high-definition camera for easy operation.
All imported core technology and original parts from Europe and America.
Camera and cabin lighting system, real-time view the test position of the sample.
Reliable power supply over-current and short-circuit protection to ensure equipment safety.
Automatic control test system, convenient for customers to use.

The current IEC standard is PY/TD-GC-MS (thermal cracking/ Thermal desorption-gas chromatography-mass spectrometry detector), where the thermal cracking temperature is high, up to 1200 degrees, many large molecular substances are cracked into small molecular substances, which will Interference and false positives to the results, so need to use MS mass spectrometers to qualify.

LISUN EDX-4 RoHS 2.0 test equipment (RoHS testing machine) use EDX-4 micro-cracking desorption technology (thermal cracking/thermal desorption-gas chromatography), we only need to quantify the corresponding o-benzenes, so our heating range is set in the range of 200°C-450°C, so that all four o-benzenes are volatilized and enter GC (gas chromatograph) for quantification without affecting the results of other macromolecular substances. It fully meets the requirements of IEC62321-8 and is more reasonable and scientific to set a more accurate temperature range.
