What are the 10 substances restricted in RoHS?

The RoHS Directive currently restricts the use of ten substances: lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE), bis(2-ethylhexyl) phthalate (DEHP), butyl benzyl phthalate (BBP), dibutyl phthalate (DBP) and diisobutyl phthalate (DIBP).



RoHS Restricted Substances (6 + 4)

RoHS specifies maximum levels by weight for the following 10 restricted materials.

The first six applied to the original RoHS while the last four were added under RoHS 3.

Four of the substances also have Chemical Abstracts Service (CAS) numbers.

CAS is a global registry of 150 million chemical substances.


Cadmium (Cd): < 100 ppm (0.01%)

Cadmium is used in electronic equipment, car batteries, metal coatings, and pigments. Known human carcinogen that affects multiple organ systems. CAS number = 7440-43-9.

Lead (Pb): < 1000 ppm (0.1%)

Lead is used in solder, lead-acid batteries, electronic components, cable sheathing, x-ray shielding, and in the glass of cathode-ray tubes. Known human carcinogen that affects the nervous and renal systems. CAS number = 7439-92-1.


NOTE: RoHS 0.1% lead amounts are exempted when used as an alloying element in steel, aluminum, copper; in specific solders; and in specific glass and ceramic applications up through 2024. For more information, see RoHS Annex III Lead Exemptions.


Mercury (Hg): < 1000 ppm (0.1%)

Mercury is used in batteries, switches, and thermostats, and fluorescent lamps. Known human carcinogen that affects multiple organ systems. CAS number = 7439-97-6.


Hexavalent Chromium (Cr VI) < 1000 ppm (0.1%)

Chromium VI is used in chrome plating, dyes, and pigments. While some forms of chromium are non-toxic, chromium VI can produce toxic effects in multiple organ systems. CAS number = 18540-29-9.

.Polybrominated Biphenyls (PBB): < 1000 ppm (0.1%)


Also known as congeners, PBBs are flame retardants found in computer monitor and TV plastic enclosures.

They have been found in indoor dust and air through evaporation. Known human carcinogen that affects the endocrine system.


Polybrominated Diphenyl Ethers (PBDE): < 1000 ppm (0.1%)


Similar to PBBs - added to plastic enclosures to make them difficult to burn. Known human carcinogen that affects the endocrine system.


Bis(2-Ethylhexyl) phthalate (DEHP): < 1000 ppm (0.1%) (RoHS 3)


DEHPs are used to soften PVC and vinyl insulation on electrical wires and in medical tubing. Known human carcinogen that affects the immune and reproductive systems.


Benzyl butyl phthalate (BBP): < 1000 ppm (0.1%) (RoHS 3)


These are used to soften PVC and vinyl insulation on electrical wires.


Dibutyl phthalate (DBP): < 1000 ppm (0.1%) (RoHS 3)


DBPs are part of the di-n-phtalate family used to soften PVC and vinyl insulation on electrical wires.
Diisobutyl phthalate (DIBP): < 1000 ppm (0.1%) (RoHS 3)


These are also used to soften PVC and vinyl insulation on electrical wires.

How does pressure relief work?

Pressure release valves are designed to open and discharge excessive pressure above the valve set point, either to atmosphere the pressure or pipe it away to a different location. Pressure relief valves are also commonly called circulating relief valves or pressure sustaining relief valves.





Relief valve


A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; excessive pressure might otherwise build up and create a process upset, instrument or equipment failure, explosion, or fire.




Pressure relief


Excess pressure is relieved by allowing the pressurized fluid to flow from an auxiliary passage out of the system. The relief valve is designed or set to open at a predetermined set pressure to protect pressure vessels and other equipment from being subjected to pressures that exceed their design limits. When the set pressure is exceeded, the relief valve becomes the "path of least resistance" as the valve is forced open and a portion of the fluid is diverted through the auxiliary route.
In systems containing flammable fluids, the diverted fluid (liquid, gas or liquid-gas mixture) is either recaptured[1] by a low pressure, high-flow vapor recovery system or is routed through a piping system known as a flare header or relief header to a central, elevated gas flare where it is burned, releasing naked combustion gases into the atmosphere.[2] In non-hazardous systems, the fluid is often discharged to the atmosphere by a suitable discharge pipework designed to prevent rainwater ingress which can affect the set lift pressure, and positioned not to cause a hazard to personnel.
As the fluid is diverted, the pressure inside the vessel will stop rising. Once it reaches the valve's reseating pressure, the valve will close. The blowdown is usually stated as a percentage of set pressure and refers to how much the pressure needs to drop before the valve reseats. The blowdown can vary roughly 2–20%, and some valves have adjustable blowdowns.
In high-pressure gas systems, it is recommended that the outlet of the relief valve be in the open air. In systems where the outlet is connected to piping, the opening of a relief valve will give a pressure build-up in the piping system downstream of the relief valve. This often means that the relief valve will not re-seat once the set pressure is reached. For these systems often so-called "differential" relief valves are used. This means that the pressure is only working on an area that is much smaller than the area of the opening of the valve. If the valve is opened, the pressure has to decrease enormously before the valve closes and also the outlet pressure of the valve can easily keep the valve open. Another consideration is that if other relief valves are connected to the outlet pipe system, they may open as the pressure in the exhaust pipe system increases. This may cause undesired operation.
In some cases, a so-called bypass valve acts as a relief valve by being used to return all or part of the fluid discharged by a pump or gas compressor back to either a storage reservoir or the inlet of the pump or gas compressor. This is done to protect the pump or gas compressor and any associated equipment from excessive pressure. The bypass valve and bypass path can be internal (an integral part of the pump or compressor) or external (installed as a component in the fluid path). Many fire engines have such relief valves to prevent the overpressurization of fire hoses.
In other cases, equipment must be protected against being subjected to an internal vacuum (i.e., low pressure) that is lower than the equipment can withstand. In such cases, vacuum relief valves are used to open at a predetermined low-pressure limit and to admit air or an inert gas into the equipment to control the amount of vacuum.


What is the meaning of pressure relief?

A pressure relief system is a device or method for reducing pressure in vessels, stages, or equipment when pressure has increased above a particular limit. The pressure relief system should allow the plant to be relieved of any source of over-pressure before damage to process equipment can occur.
