What is RoHS?

RoHS stands for hazardous substance restriction. RoHS, also known as directive 2002/95/ec, originated in the European Union and restricts the use of certain hazardous materials found in electrical and electronic products (known as EEE). All applicable products on the EU market after july1,2006 must pass RoHS compliance.

What are the restricted materials specified in RoHS?

The substances prohibited by RoHS are lead (PB), mercury (Hg), cadmium (CD), hexavalent chromium (CrVI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE) and four different phthalates (DEHP, BBP, BBP, DiBP).

Why is RoHS compliance important?

Restricted materials are harmful to the environment and pollute landfills, and are dangerous in terms of occupational exposure during manufacturing and recycling.

How to conduct RoHS compliance test on products?

Portable RoHS analyzers, also known as X-ray fluorescence or XRF metal analyzers, are used to screen and verify restricted metals. With the emergence of RoHS and four added phthalates, different tests are required to determine the content of these compounds, which are extracted with solvents. For more information, see ROHS testing.

Which companies are affected by the RoHS directive?

Any enterprise that directly sells or distributes applicable EEE products, sub assemblies, components or cables to EU countries, or sells products to distributors, distributors or integrators will be affected if they use any restricted materials Since regulations similar to RoHS have been spread to many other countries, this is no longer applicable to EU countries alone.

RoHS is also applicable to the metal industry for metal plating, anodizing, chromizing or other surface treatment on EEE components, radiators or connectors.

What is rohs2 and how is it different from the original RoHS?

Rohs2 or recast rohs2 directive 2011/65/eu, issued by the European Commission in july2011. The scope of the original RoHS has been expanded to cover all electrical / electronic equipment, cables and spare parts, and meet the requirements on or before july22,2019 according to the product category.

Any product within the scope of rohs1 requirements shall not contain any of the six restricted substances, and the company (manufacturer, importer or distributor) that puts the product on the EU market shall keep records to prove its compliance. Rohs2 requires everyone in the supply chain to maintain additional compliance records. Additional compliance record keeping (which must be kept for 10 years) can include conformity assessment, CE marking, maintaining compliance throughout the production process and self-report of non-compliance.

The proposed changes to the original ROHS directive in rohs2 (2011/65/eu) are relatively minor. No other substances have been added to the six substances currently restricted. RoHS also added RoHS category 8 (medical devices) and 9 (control and monitoring instruments) products. Rohs2 came into effect on january2,2013.

With rohs2, is it necessary to print RoHS logo?

Rohs2 is also a CE mark directive. At present, the CE mark of products is required to comply with ROHS standards. Therefore, all manufacturers of electrical / electronic products must comply with rohs2 in order to apply the CE mark on their products. The original green RoHS label with a check mark is no longer required or used because the CE mark now includes RoHS compliance.

What is rohs3 and how is it different from rohs2?

Rohs3 or directive 2015/863 added four additional restricted substances (phthalates) to the six original lists cited in REACH regulations. It also added category 11 products. Rohs3 comes into effect on July 22nd, 2019.

What is rohs5/6?

Rohs5/6 refers to the compliance of 5 of the 6 restricted substances (lead (PB) non-compliance). Lead in very specific class 8 and class 9 applications has also been exempted for several years in accordance with Annex III. For more information, please refer to RoHS Annex III lead exemption.

Will there be "rohs4"... Will there be other substances restricted in the future?

Maybe / possible. Discussions are under way (called rohspack15) to discuss possible modifications and the inclusion of seven new substances. The other seven substances being evaluated are beryllium, cobalt (dichloride and sulfate), antimony trioxide, indium phosphide, medium chain chlorinated paraffins (MCCP), nickel (sulfate and sulfamate) and tetrabromobisphenol A (TBBP-A).

What is the relationship between RoHS and reach?

Reach is a general regulation that represents registration, e-assessment, authorization, chemical restriction, and addresses the production and use of chemical substances and their potential impact on human health and the environment. Reach is monitored by ECHA and currently handles 197 substances of high concern (SVHC). Although RoHS restricts substances in electrical / electronic equipment (wiring, components, circuit boards, displays, sub assemblies, cables), reach controls all chemicals that may be used to manufacture products, including enclosures, supports, coatings, paints, solvents, and chemicals used in the manufacturing process.

It is worth noting that all RoHS restricted substances are also in the reach restricted list. The substances on the list have been identified as carcinogenic, mutagenic, reproductive toxic, bioaccumulative and toxic, or as endocrine disruptors. Please refer to the reach restricted substances list.

What is the relationship between RoHS and WEEE?

WEEE is an acronym for waste from electrical and electronic equipment. WEEE, also known as directive 2002/96/ec, regulates the treatment, recovery and recycling of electrical and electronic equipment. All applicable products on the EU market after august13,2006 must pass WEEE compliance and bear the "wheeliebin" label. WEEE compliance aims to encourage environmental safety recycling and recycling when designing electronic products. RoHS compliance is consistent with WEEE by reducing the number of hazardous chemicals used in electronic manufacturing.

In other words, ROHS specifies hazardous substances used in the manufacture of electrical and electronic equipment (EEE), while WEEE specifies the disposal of the same equipment. For details, see WEEE compliance.

What is the relationship between RoHS and ELV directives?

The EU ELV directive is related to automobiles, while ROHS directive covers various electrical and electronic products in many industries. The ELV directive applies to cables, wires and related components used in transport vehicles. It entered into force on 1 July 2003 and restricts the use of lead, mercury, cadmium and hexavalent chromium (also subject to RoHS restrictions).

In general, XLP (cross linked polyethylene) insulated automotive wires, such as SAE (Society of Automotive Engineers) types Sxl, GXL and TXL, comply with this directive. However, PVC insulated automotive wire types (such as GPT, twp, SGT and SGX) may contain lead and therefore may not meet the requirements unless specifically required in the procurement specification.

What is the relationship between RoHS and conflict minerals (t3&g)?

Mainly in the form of all material declaration (FMD). Generally, ROHS, reach and conflict minerals (t3&g) are listed together in the compliance statement. The conflict minerals are tantalum, tungsten, tin and gold - if they come from the Democratic Republic of the Congo (DRC), they are called 3tg minerals. The Democratic Republic of the Congo also mines cobalt for the manufacture of batteries for electric vehicles. Cobalt mining volume will increase significantly to meet this demand. Under the Dodd Frank act, all listed companies must report the source of conflict minerals to the sec.

Is RoHS applicable to batteries?

may not. All batteries, regardless of type or application, are protected by the EU battery directive (2006/66/ec and amendment 2013/56/eu). The battery directive limits the use of lead to 0.004%, mercury to 0.0005% and cadmium to 0.002% (medical devices / equipment and alarm / emergency systems do not include cadmium).

Note: according to China RoHS, the battery includes / covers. Considering the size of the battery pack, this has special significance for the electric vehicle market.

Is RoHS applicable to RFID tags?

Yes, both passive and active RFID are included under RoHS. In the case of packaging, it belongs to category 3. If an RFID tag is permanently attached to a device or device, it belongs to the category of the parent device.

Does RoHS apply to printer cartridges?

Only if the cartridge contains electrical components that require current or electromagnetic fields to function. Printer cartridges that consist only of ink and containers, and do not have electrical components, are not applicable.

What is the relationship between RoHS and HIPAA?

The healthcare industry is regulated by HIPAA and has its own compliance requirements. If you manufacture eeps for the healthcare industry, you also need to obtain HIPAA certification in accordance with the safety rules. This applies not only to medical equipment, but also to office equipment, including scanners, printers, hard drives, hardware security modules (HSMS), smart card readers, network devices, shredders, media degaussers, and hard drive "destroyers" that bend, break, and damage retired hard drives. For details, see hipaa101.

How to implement RoHS compliance and what are the penalties?

By national law enforcement agencies such as NMO (National Survey Office). Penalties and fines for non-compliance may vary widely among EU countries, but include fines and imprisonment in some member states.
