RoHS 2 Creeps Up on the Industry

As RoHS recast compliance rules take effect in Europe, concern lingers over companies’ preparedness to meet the new requirements

Gary Nevison and the folks in the element14 community are doing their part to educate the electronics community about the new requirements of RoHS 2, an update to the European Restrictions on Hazardous Substances (RoHS), which took effect January 2. Element14 launched an updated e-book detailing the new requirements, and Nevison may soon be on the lecture circuit delivering that message to suppliers, customers, and others selling electronic components and finished products in Europe. Nevison is head of legislation for Premier Farnell, element14’s parent company, and he says the RoHS update is taking many in the industry by surprise.

“I think there are many areas of industry probably not prepared for this,” explains Nevison, pointing to new requirements for designating products with a CE mark, which means they conform to European standards, in particular.

The new requirements are part of a revision to the RoHS directive, known as the RoHS recast that began in 2010. The new requirements update the original 2006 directive, which banned the use of six substances—lead (Pb), mercury (Hg), hexavalent chromium (Cr (VI)), cadmium (Cd), polybrominated biphenyl flame retardants (PBB), and polybrominated biphenyl ether flame retardants—in eight categories of electrical and electronic equipment. RoHS 2, as it is known, broadens the scope of the directive to include additional products and product categories and makes RoHS compliance a CE directive, placing more data collection work on companies throughout the supply chain.

Some industry watchers say RoHS 2 has fallen off of many companies’ radar screens because it was a much bigger deal due to its newness in 2006. Quite simply, companies have been through it once, are largely familiar with the issue, and have procedures in place to address it. Further complicating the issue for American distributors is local legislation on counterfeit components and conflict minerals that is drawing more immediate attention. But Nevison and others caution against putting RoHS 2 on the back burner as environmental concerns become more acute worldwide and the regulatory climate heats up.

“Make no mistake about it, the authorities will be on this. They will come to check you for these technical files,” Nevison says, pointing to the need for documentation that products comply with European Union directives. He adds that each European state retains the responsibility for enforcing the rules under RoHS 2. “These are the facts. It’s getting more stringent rather than the other way around.”

More Products, More Documentation

Identifying products with a CE mark, which stands for Conformité Européenne (or European Conformity), ensures that they comply with EU regulations. The CE Mark directive places more data collection work on distributors and importers as they seek to verify RoHS compliance, Nevison explains.

“The main impact on industry is the inclusion of RoHS as a CE directive,” says Nevison. “[Companies] need to supply lots and lots of new documentation. The CE Mark is the biggest challenge to us at this point in time.”

In most cases, manufacturers are responsible for documentation and CE Mark designation, but in some instances the responsibility falls to the distributor or importer—especially when the distributor is selling the product under its own brand. The issue is further complicated because the CE Mark now applies to low-cost development boards, which is a sticking point for many manufacturers.

“I think some companies in all honesty didn’t think they needed to comply, but they do,” says Nevison, pointing to differing views over how development boards or kits are classified. “I think what deceives people is that these small, open PCBs don’t look like a piece of finished equipment. But as soon as they’re put in a PC to make them work, if you like, they are classed as finished equipment.”

Development boards that were already on the market before January 2, 2013, do not need to be remarked. RoHS 2 applies to any development boards or kits placed on the market after that date. Nevison says Premier Farnell has been in touch with all of its development kit suppliers to determine their compliance, to varying degrees of success.

“Some say they are in compliance, some say they’re working on it, and some haven’t done anything,” Nevison explains, adding that the issue may lead to distributors dropping certain products.

The other key issue is the broadened scope of the directive itself. RoHS 2 now includes products that depend on electric currents or electromagnetic fields for at least one of their functions. Previously, the directive applied only to products that depended on electric currents or electromagnetic fields to work properly. This widens the field of covered products. Nevison points to two examples: a gas stove with an electric clock and a gas lawnmower with an electric ignition, neither of which was covered under RoHS 1. The gas stove is in scope as of January 2, and the lawnmower will be in scope as of July 2019.

“So it will capture some different products,” Nevison explains. “And it’s worth saying there are lots and lots of exclusions this time. Those will be reviewed by July 2014, and they may even be extended.”

Nonetheless, RoHS 2 has a number of phase-in dates for new product categories. Medical devices and monitoring and control equipment must be in compliance after July 2014, with in vitro diagnostics coming into scope in 2016 and industrial monitoring and control instruments in July 2017. What’s more, RoHS 2 adds an eleventh category in July 2019 when all electrical and electronic equipment not captured in categories 1 to 10 of the directive come into scope.

Nevison emphasizes that revisions are ongoing, noting that the commission overseeing the RoHS directive plans to review more substances next year while also reviewing whether or not further exclusions should be granted.

Robin Gray, chief operating officer for the Electronic Components Industry Association, which represents manufacturers, distributors, and independent representatives in the electronics industry, says the modifications to the RoHS directive are part of a larger trend toward increased regulation worldwide. He points to pending RoHS legislation in China, new U.S. rules surrounding conflict minerals sourcing, varying state-level bans on certain chemicals in the United States, and the simmering concern over the supply of rare earth minerals commonly used in electronics equipment.

“I think the industry’s going to see more and more regulation—environmentally or otherwise,” says Gray. “The other issue is that so much of electronics uses rare earth minerals, and the supply of that is relatively limited—and some very limited. If you’re going to ban certain metals or certain chemicals, how viable are certain components for the long term? You’ve got to find new technologies, processes, or chemical formulas, or you’ve got to be willing to make a trade off. I think this is only going to become more of an issue.”
