RoHS is the English abbreviation of the restriction of the use of certain hazardous substances in electrical and electronic equipment. ROHS standard: iec62321, directive 2011/65/eu. You are no stranger to RoHS. Recently, many people asked what are the 10 RoHS tests? What is the test standard? This article has collected and sorted out some materials, which are expected to be of great reference value to readers.

At present, the version of RoHS is 2.0, and 6 tests are mandatory for the export of products to the EU. 10 compulsory tests will be conducted from July 22, 2019. Rohs2.0 is an upgraded version of the old ROHS test items. 2011/65/ec directive was changed to rohs10 items: cadmium (CD), lead (PB), mercury (Hg), hexavalent chromium (cr6+), di-n-butyl phthalate (DBP), polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs), n-butyl benzyl phthalate (BBP), 2-hexyl phthalate (DEHP), hexabromocyclododecane (hbcdd).

RoHS 2.0 test items (RoHS 10 items):

1. Lead (PB), examples of using this substance: solder, glass, PVC, stabilizer;

2. Cadmium (CD), examples of using this substance: switches, springs, connectors, housings, PCBs, contacts, batteries;

3. Mercury (Hg), (mercury) examples of using this substance: temperature controllers, sensors, switches and relays, bulbs;

4. Hexavalent chromium (cr6+), examples of using this substance: metal with corrosive coating;

5. Polybrominated biphenyls (PBBs), examples of using this substance: flame retardant, PCB, connector, plastic shell;

6. Polybrominated diphenyl ethers (PBDEs), examples of using this substance: flame retardant, PCB, connector, plastic shell.

7. Diisobutyl phthalate (DiBP) is used as a plasticizer for PVC, a substitute for DBP, and a plasticizer for cellulose resin, vinyl resin, nitrile rubber and neoprene.

8. Phthalic acid (2-ethylhexyl ester) (DEHP) is mainly used as PVC plasticizer, and PVC is used as insulator in electronic and electrical equipment, such as cables and wires. A small amount of DEHP is used for other non polymer applications, such as ceramics of electronic products or electrolyte of capacitors.

9. Dibutyl phthalate (DBP) is mainly used in PVC parts such as cables, sockets, pipes and shock absorbers in combination with other plasticizers. In addition, it is also used in some non polymers such as paints, adhesives, sealants and printing inks.

10. Toluene butyl phthalate (BBP), a colorless transparent oily liquid. Slightly aromatic, used as plasticizer for PVC, vinyl chloride copolymer, cellulose resin, natural and synthetic rubber.

Ten test standard limits:

1. CD cadmium 100ppm

2. Pb lead 1000ppm

3. Hg mercury 1000ppm

4. Cr (VI) hexavalent chromium 1000ppm

5. PBBs polybrominated biphenyls 1000ppm

6. PBDEs polybrominated diphenyl ethers 1000ppm

7. DEHP diethylhexyl phthalate 1000ppm

8. BBP butyl benzyl phthalate 1000ppm

9. DBP dibutyl phthalate 1000ppm

10. DiBP diisobutyl phthalate 1000pmm
