Japan PSE certification introduction
PSE certification is a compulsory safety certification in Japan. It
is used to prove that electrical and electronic products have
passed the safety standards test of the Japanese Electrical and
Material Safety Law (DENAN Law) or international IEC standards.
Japan's DENTORL Act (Electrical Device and Material Control Act)
stipulates that 506 products must pass safety certification to
enter the Japanese market. Among them, 165 types of A products
should obtain the diamond-shaped PSE mark, and 341 types of B
products should obtain the circular PSE mark.
Since April 1, 2001, the Electrical Product Control Act (DENTORL)
has been officially renamed the Electrical Product Safety Act
(DENAN). Unlike the control of the agreement provisions of the
previous regulatory system, the new system will ensure product
safety by unofficial agencies.
Basic information of PSE certification
Whether mandatory: mandatory
Certificate validity: for diamonds, 3-7 years, product based. For
round, no validity period, no certificate, only VOC can be issued
Factory inspection requirements: For diamonds, only the first
factory inspection is required, no annual review. For round, no
factory inspection requirements
Licensee requirements: for diamond, factory / importer. For round,
no requirements
Technical information: Voltage frequency AC 100V, 50Hz / 60Hz, plug
JIS 8303
Certification classification
According to Japan's "Electrical Product Safety Law" PSE
certification is divided into two categories.
PSE diamond certification: Among them, it is easy to cause electric
shock, fire and other accidents, and there are 165 kinds of
products with greater danger, which are classified as "specific
electrical products — called Class A electrical products", such as
chargers and adapters;
PSE circular certification: the remaining 341 products with less
harmfulness are classified as "non-specific electrical
products-called Class B electrical products", most of which are
large and small household electrical appliances, lighting products,
lithium batteries, etc.
Applicable product range
Diamond PSE
Electric wires, wiring appliances, current limiters, transformers,
stabilizers, electric heating appliances, electric power
application machinery, AC electrical machinery, portable
generators, other AC machinery, electrical conduits, small AC
motors, light sources and light sources Applied machinery,
batteries, etc. belong to the product range specified by the Safety
Law for Certain Electrical Supplies, such as: DC power supply
devices, switches and sockets, electric water heaters, power cords
and plugs, other household appliance transformers (AC-AC power
products), etc. 165 products.
Round PSE
Products that fall outside the specific electrical appliance safety
law, such as: electric blankets, electric steamers, electric irons,
electric ovens, microwave ovens, hair humidifiers, refrigerators,
electric mixers, electric egg cookers, and electric insulation
basins , Hair dryer, electric humidifier, projector, washing
machine, incandescent bulb, fluorescent lamp, table lamp,
decorative lamp, advertising lamp, lithium battery and all 341
products such as LED bulbs and LED lamps.
Application process
1. The client prepares samples and materials to submit to the
testing agency
2. The testing organization's laboratory performs the test. If it
is a PSE round, LCS will issue a statement letter.
3. For PSE diamonds, an inspection is needed.
4. After passing the test and inspection, the issuing authority
issues a PSE diamond certificate
Application materials
