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.

LS860 luminous Intensity Distribution Tester is Designed According to CIE 127-2007

The full name of CIE 127-2007 is<MEASUREMENTS OF LEDS>.This Technical Report has been prepared by CIE Technical Committee 2-45 of Division 2 “Physical Measurement of Light and Radiation” and has been approved by the Board of Administration of the Cooission Internationale de I’Eclairage for study and application. The following is the original content of CIE 127-2007.


A goniophotometer is a device to measure the luminous intensity of the source(or illuninance from the source at a given distance) in many different directions from the source. Compared with the sphere method, the goniophotometer method is theoretically free from errors due to differences in intensity distribution of the light source under test. It does not require total luminous flux standards. Instead, it requires longer time for measurement of each sample.

The photometer head of the goniophotometer should meet the spectral responsivity requirement given in Section 3.3. The calibration of the photometer head(and spectral mismatch correction) should follow the recommendation for Averaged LED Intensity measurement(Section 5). The instrument also requires careful shielding of ambient light and reflected light within the instrument.

LISUN designed the LS860 luminous Intensity Distribution Tester according to the CIE 127_2007 6.2 Methods of flux measurement.. It is a precise instrument for measuring LED luminous intensity.

IEC 60068-2-6 <Environmental testing –Part 2-6: Tests – Test Fc: Vibration (sinusoidal)> consists basically of subjecting a specimen to sinusoidal vibration over a given frequency range or at discrete frequencies, for a given period of time. A vibration response investigation may be specified which aims at determining critical frequencies of the specimen.The following is the original content of IEC 60068-2-6.

This part of IEC 60068-2-6 gives a method of test which provides a standard procedure to determine the ability of components, equipment and other articles, hereinafter referred to as specimens, to withstand specified severities of sinusoidal vibration. If an item is to be tested in an unpackaged form, that is without its packaging, it is referred to as a test specimen. However, if the item is packaged then the item itself is referred to as a product and the item and its packaging together are referred to as a test specimen.

The purpose of this test is to determine any mechanical weakness and or degradation in the specified performance of specimens and to use this information, in conjunction with the relevant specification, to decide upon the acceptability of the specimens. In some cases, the test method may also be used to demonstrate the mechanical robustness of specimens and or to study their dynamic behavior. Categorization of components can also be made on the basis of a selection from within the severities quoted in the test.

LISUN designed the LVD-100KG Vibration Generator System according to the IEC 60068-2-6 Part 2 standard. It can test Sine Wave, Frequency Modulation, Sweep Frequency, Programmable, Frequency Doubling, Logarithm and so on.

TTC-1 Tracking Test Chamber is Designed According to IEC60112-2009

The full name of IEC60112-2009 is <Method for the determination of the proof and the comparative tracking indices of solid insulating materials>. It has been prepared by subcommittee 15E: Methods of test, of IEC technical committee 15: Insulating materials.The following is the original content of IEC60112-2009 Principle.

The upper surface of the test specimen is supported in an approximately horizontal plane and subjected to an electrical stress via two electrodes. The surface between the electrodes is subjected to a succession of drops of electrolyte either until the over-current device operates, or until a persistent flame occurs, or until the test period has elapsed.

The individual tests are of short duration (less than 1 h) with up to 50 or 1 00 drops of about 20 mg of electrolyte falling at 30 s intervals between platinum electrodes, 4 mm apart on the test specimen surface. An a.c. voltage between 1 00 V and 600 V is applied to the electrodes during the test.

During the test, specimens may also erode or soften, thereby allowing the electrodes to penetrate them. The formation of a hole through the test specimen during a test is to be reported together with the hole depth (test specimen thickness). Retests may be made using thicker test specimens, up to a maximum of 1 0 mm.

NOTE The number of drops needed to cause failure by tracking usually increases with decreasing applied voltage and, below a critical value, tracking ceases to occur.

LISUN designed TTC-1 Tracking Test Chamber. Due to the electric stress and electrolytic contamination of the surface. This method simulates tracking currents on insulation material by providing drops between electrodes. During the process of normal use, insulating material may be exposed to moisture and dirt, and may cause stress and fire hazard if it is conductive.
