What is PSE certification?In 1995, Japan enacted a new law banning products , the new regulations no longer
follows the principle of error -party liability , and the use of European and North
American practice ( innocent party liability principle ) , the party responsible for product
safety requirements for the product manufacturers, importers Manufacturers ,
distributors and so on.
April 1, 2001 , before the Japanese Electrical Appliance and Material Control Law
(DENTORI) will control the products are divided into A, B two categories, wherein,
A class includes 165 kinds of products , mainly in the power cord, fuses, switches ,
transformers , ballast , etc. ;B class includes 333 kinds of products, mainly lighting,
household appliances , office equipment. Class A products must obtain government
mandatory certification , namely T flag , and the flag is only by MITI ( MITI ) issued .
Class B product conformity shall be made self-proclaimed or apply for third-party
certification , such as TUV Rheinland can mark the S flag .
After 1 April 2001 , Electrical Appliance and Material Safety Law (DENAN) replaces
DENTORI France , while Japan has abolished the T flag , the government no longer
issue certificates directly , but to authorize a third party certification body for product
conformity assessment tests.
New regulations the product is divided into " specific electrical and Materials " and "non-
specific electrical and Materials ." The " specific electrical and Materials " includes a total
of 112 kinds of products ; "non-specific electrical and Materials " includes 340 kinds of
products. To enter the Japanese market, " specific electrical and Materials " products
must obtain third-party certification , labeling PSE ( diamond ) symbol ; "non-specific
electrical and Materials " products shall be made self-proclaimed or apply for third-party
certification , labeling PSE ( Round ) sign.
New law reduced the number of categories of products , more products are classified as
non- classified products " and no longer subject to DENAN constraints, and some
previously classified as "A Class " products are now classified as " specific electrical
and Materials ."
