Product Information

One of the major differences between lead-containing and lead-free solder pastes is the "flow" of the solder in its liquid state. Lead-containing solder has a lower surface tension, and tends to move slightly to attach itself to exposed metal surfaces that touch any part of the liquid solder. Lead-free solder conversely tends to stay in place where it is in its liquid state, and attaches itself to exposed metal surfaces only where the liquid solder touches it. RoHS is often referred to as the "lead-free directive", but it restricts the use of the following ten substances:

There are a number of analytical techniques for the rapid measurement of BFR concentrations. X-ray fluorescence spectroscopy can confirm the presence of bromine (Br), but it does not indicate the BFR concentration or specific molecule. Ion attachment mass spectrometry (IAMS) can be used to measure BFR concentrations in plastics. The BFR ban has significantly affected both upstream (plastic material selection) and downstream (plastic material recycling). [ citation needed] 2011/65/EU (RoHS 2) [ edit ]If you upgrade your installation with both LED lighting and smart lighting control systems you can reduce energy consumption by as much as 90%, while also improving the well-being of your building’s occupants. If you consider the fact that more than 80% of all existing light installations in offices, educational buildings, health care buildings, and Industrial buildings in the EU use fluorescent or high-pressure lamps, the potential for energy saving becomes enormous. Adverse effects on product quality and reliability, plus high cost of compliance (especially to small business) are cited as criticisms of the directive, as well as early research indicating that the life cycle benefits of lead-free solder versus traditional solder materials are mixed.

The maximum permitted concentrations in non- exempt products are 0.1% or 1000 ppm (except for cadmium, which is limited to 0.01% or 100ppm) by weight. The restrictions are on each homogeneous material in the product, which means that the limits do not apply to the weight of the finished product, or even to a component, but to any single material that could (theoretically) be separated mechanically– for example, the sheath on a cable or the tinning on a component lead.

Manufacturers will find that it is cheaper to have only a single bill of materials for a product that is distributed worldwide, instead of customising the product to fit each country's specific environmental laws. Therefore, they develop their own standards, which allow only the strictest of all allowable substances. Lasky, Ron.

The closely related WEEE ( Waste Electrical and Electronic Equipment Directive), which became law simultaneously with RoHS, depicts a waste-can logo with an "X" through it and often accompanies the CE mark. I’ve been going nuts on the static/record handling thing for a month now and this is what I have learned; Took me 50 plus years of playing records also...... Investing in Glamox sustainable lighting solutions is a surefire way to play by the rules. It is a great choice if you want to do your part to protect the environment, all while providing light that supports people’s comfort and well-being. Fry et al. 28 previously reported that the UKB is not representative of the entire UK population, as it notably, includes healthier and more educated participants than the average population. Such an ascertainment on traits which are negatively correlated with inbreeding (e.g., educational attainment (EA) or height 28), may lead the prevalence of EI in the UKB to be an underestimation of the actual prevalence of EI in the UK population. As a consequence, our estimate of prevalence of EI is likely conservative, although the magnitude of the underestimation is difficult to predict as it depends on many other unknown factors which might differ between UKB participants and the general population.

RoHS mercury exemption 3(a)-(c) - cold cathode fluorescent lamps and external electrode fluorescent lamps for special purposes Tri-band phosphor with normal lifetime and a tube diameter > 17mm and ≤28mm (for example T8): 3.5mg per lamp. This exemption has been revoked. It expires on 1 February 2024. With the recast of the original RoHS (I) Directive (2002/95/EC), the scope of the directive was decoupled from the scope of the WEEE Directive and an open scope was introduced. The RoHS (II) Directive (2011/65/EU) was applicable to all electrical and electronic equipment. Scope limitations and exclusions were specifically introduced in Article 2(4) a) – j) of the recast Directive. All other EEE was in scope of the Directive, unless specific exemptions have been granted through Commission delegated acts (see next paragraph). Mercury in high pressure sodium (vapour) lamps for general lighting purposes in lamps with improved colour rendering index Ra > 60: P ≤ 155W: 30mg per burner. This exemption has been revoked.
