The Restriction of Hazardous Substances Directive (RoHS) is an abbreviation of the Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment. The directive was adopted by the EU, and took effect in July 2006. It restricts the use of six, specified hazardous materials (listed below) in the manufacture of various types of electronic and electrical equipment.
･Pb(Lead) 1000ppm
･Cd(Cadmium) 100ppm
･Cr6＋(Hexavalent chromium) 1000ppm
･Hg(Mercury) 1000ppm
･PBB(Polybrominated biphenyl) 1000ppm
･PBDE(Polybrominated diphenyl ethers) 1000ppm

Following this, in June 2015, (EU) 2015/863 was publicly released to replace Annex II of 2011/65/EU. Four substances were added, bringing the total number of regulated substances to 10.
･DEHP (di phthalate-2-ethylhexyl) 0.1 wt% （1,000 ppm)
･BBP（Benzyl butyl phthalate） 0.1 wt% （1,000 ppm）
･DBP (Di-n-butyl phthalate） 0.1 wt% （1,000 ppm）
･DIBP（Diisobutyl phthalate） 0.1 wt% （1,000 ppm）

The CE marking is used for EU market supervision. By affixing the CE mark to a product, the manufacturer declares that it complies with EU requirements, and the product is thus able to move freely within the European market. 

Low Voltage Directive: ensures that the product accompanied by all the appropriate marks, indications and instructions so that it will be used properly and safely and also that it is designed to provide protection against hazards arising from itself and also has protection against hazards possibly caused by external influences.

EMC Directive: ensures that the electromagnetic disturbance the product emits does not exceed a level allowing radio and telecommunication equipment and other apparatus to operate as intended. It evaluates the level of electromagnetic disturbance the product generates, and whether it has an adequate level of intrinsic immunity to electromagnetic disturbance from external sources.

MSDS (material safety data sheet) contains information concerning chemicals and products containing them necessary for their safe handling. Standardized under JIS Z 7250 (revised edition, December, 2005), the content is as follows. 

- Product and business enterprise information
- Summary of hazards and toxicity
- Information on chemical content and structure
- Emergency measures
- Measures in case of fire
- Measures in case of leakage
- Precautions in handling and storage
- Measures for explosion prevention and protection
- Physical and chemical properties
- Stability and reactivity
- Hazard information
- Environmental impact information
- Precautions in disposal
- Precautions in transport
- Applicable laws and regulations

PSE (Electrical Appliance and Material Safety Law) is the law establishing technological standards concerning the safety of electrical appliances. In addition to restricting the manufacture, import, and sale of electrical appliances and materials, the laws aims to prevent danger and the occurrence of damage from electrical appliances by promoting voluntary action by private businesses to ensure the safety of electrical appliances. As of April, 2006 electrical appliances which have not been granted the PSE mark cannot be sold (excepting certain used appliances). VESSEL CO., Ltd. carries out electrification inspections, dielectric strength tests and insulation resistance tests on all manufactured units of models SDJ-05R, SDF-14, IPC-20, and IPC-40, which require the PSE mark.
