Why RoHS Compliance Testing is important

Let’s first be aware of what exactly RoHS is. RoHS and why it is thought to be so important. RoHS is the initial acronym as the Restriction of Hazardous Substances. The term is often referred to as Directive 2002/95/EC. It is a direct result of directly from the European Union and is framed only to limit the use of certain hazardous and harmful substances products, which are commonly found in electronic and electrical products. The RoHS test is believed essential because some restricted substances that the article below outlines pose a risk for the natural environment. They’re mostly considered to pollute landfills in a significant way and are even considered to be hazardous in relation to the exposure to occupational hazards that occur during the manufacturing process and their disposal. RoHS Compliance Testing RoHS Compliance Testing is now thought to be the most essential standard procedures for most big or new manufacturers distributors, sellers, as well as recyclers of electronic and electrical components. It also includes the equipment that is sold and used within the European Union.

The EU RoHS Directives are set in order to limit or restrict the use of hazardous and hazardous substances in all electronic and electrical products. These directives also cover medical devices, as well as monitoring and control equipment. This directive acts as an insurance policy by offering replacement and safe/preserved alternatives. This directive is intended to be used with regard to devices that operate or function at 1000 VAC or 1500 VAC. It also comprises a set of 11 sections that include electrical bulbs, household luminaries medical devices, as well as equipment for monitoring and control.

Therefore, there are a few labs set up to assist in assisting customers to ensure RoHS conformance. They are specialized in performing rapid, reliable and accurate RoHS testing. In addition they also test the components to ensure that the various levels of the substances that are restricted are tested. The majority of these labs are equipped with the latest technologies to analyze RoHS for mercury, lead, Cadmium, and hexavalent chromium. They also have to find out if the total amount of Bromine is less in comparison to the limit for the compound that is the most abundant in Bromine or the reverse. Therefore, it is helpful to determine if the material is in compliance with RoHS specifications or not.

The capabilities of labs performing RoHS Compliance Testing include

Testing products – the most important components in the products are examined.
Assessment of hazardous chemical substances – these could include mercury, lead, Cadmium, hexavalent chrome and bromine.
Different improved testing techniques.

Some of the most popular methods labs employ to measure the concentrations of the restricted RoHS samples in test tubes are spectrum analysis and wet chemical methods.

RoHS typically has set aside an amount that is set as the maximum concentrations for the restricted substances in each. The values are typically fixed at 0.1 percent, however they are not excluding the cadmium that has an upper limit of 0.01 per cent.

RoHS Directive

The reason there is an obligation to conduct RoHS testing for compliance is because of the fact that numerous directives have been formulated. Thus the Restriction of hazardous substances directive or RoHS Directive. RoHS Directive came into effect on July 1st in the year 2006.

The directives initially developed within the European Union with the aim to ensure and safeguard the health of people and the environment surroundings from dangerous chemicals. This is accomplished by limiting the use of six harmful and poisonous chemicals within the main electronic and electrical products.

The hazardous chemicals controlled are

Mercury (Hg) 100ppm

Hexavalent Chromium (Cr (VI)): 1000 ppm

Cadmium (Cd): 100ppm

PBB: Polybrominated Biphenyls (PBB) 1000 ppm

Lead (Pb) 1,000ppm

The Polybrominated Diphenyl Ethers (PBDE) 1000 ppm

Bis(2Bis(2 Ethylhexyl) Phthalate (DEHP) 1000ppm

Benzyl Butyl Phthalate (BBP) 1000ppm

Dibutyl Phthalate (DBP) 1,000ppm

Disobutylphthalate (DIBP) 1000ppm

To ensure that a product is RoHS conforming, a variety of RoHS compliance tests are performed to identify the presence of certain elements. Additionally the quantities and amounts of the above dangerous chemical substances are tested in the homogenous components in the products. To a large extent they are required to conduct the initial screen test of RoHS in order to determine if there is significant quantities of these chemicals should they be they are required.

Usually, these tests are based on a mixture of XRF, FIR, SEM/EDX, and sometimes AAS to determine if it is RoHS conforming or not.
