RoHS是由歐盟立法制定的一項強制性標準，它的全稱是《關於限制在電子電氣設備中使用某些有害成分的指令》(Restriction of Hazardous Substances)。該標準已於2006年7月1日開始正式實施，主要用於規範電子電氣產品的材料及工藝標準，使之更加有利於人體健康及環境保護。該標準的目的在於消除電器電子產品中的鉛、汞、鎘、六價鉻、多溴聯苯和多溴二苯醚（注意：PBDE正確的中文名稱是指多溴二苯醚，多溴聯苯醚是錯誤的說法）共6項物質，並重點規定了鎘的含量不能超過0.01%。
1 Mercury in compact fluorescent lamps not exceeding 5 mg per lamp
2 Mercury in straight fluorescent lamps for general purposes not exceeding:
- halophosphate 10 mg
- triphosphate with normal lifetime 5 mg
- triphosphate with long lifetime 8 mg.
3 Mercury in straight fluorescent lamps for special purposes.
4 Mercury in other lamps not specifically mentioned in this Annex.

24 Lead in finishes of fine pitch components other than connectors with a pitch of 0.65mm or less with NiFe lead frames and lead in finishes of fine pitch components other than connectors with a pitch of 0.65mm or less with coppler lead frames.
25 Lead in solders for the soldering to machined through hole discoidal and planar array ceramic multilayer capacitors.
26 Lead oxide in plasma display panels (PDP) and surface conduction electron emitter displays (SED) used in structural elements, notably in the front and rare glass dielectric layer, the bus electrode, the black stripe, the address electrode, the barrier ribs, the seal frit and frit ring as well as in print pastes.
27 Lead oxide in the glass envelope of Black Light Blue (BLB) lamps.
28 Lead alloys as solder for transducers used in high-powered (designated to operate for several hours at acoustic power levels of 125 dB SPL and above) loudspeakers.
