Revision of "Ordinance for Technical Requirements of Electrical Appliances and Materials"  
1. Purpose and reason of revision  
Industrial Structure Council Consumer Economic Committee Product Safety Subcommittee on May 2010, 
made a proposal  to the Minister that 4  items,  ①Electric vacuum cleaners with over  1kW, ②LED lamps, 
③Lithium-ion batteri es having special constructions , and ④Power supply cord  set for extension , should be  in 
the scope of the Electrical Appliances and Materials Safety  Act to prevent accidents resulting from electrical 
products . 
In response to the conclusion of the Subcommittee , METI promulgated the revised Cabinet Order of the Law 
on July  2011, in order to designate 3 items (Electric vacuum cleaners with a rated power consumption of over 
1kW but not more than 1.5kW, LED -lamps, and Lithium -ion batteries having special constructions) as  subject 
to the Law. Regarding Power supply cord set  for extension, METI shall revise the ordinance for determining 
technical requirements.  The Specific details are as follows . 
① Electric vacuum cleaners with over 1kW  
The rated power electric consumption of the Electric vacuum cleaner will expand the regulation reach into 
1.5kW  or less . 
② LED-lamps  
LED-lamps and LED -luminaires will be regulated as other electrical appliances and materials (Category B) . 
③ Lithium -ion batteries having special constructions  
Lithium -ion batteries, designed to fix to appliances by soldering or other joining methods so that it cannot be 
easily removed, or  having oth er special constructions, will be regulated.  
④ Power supply cord set for extension  The technical requirements for extension cord set, that is , a set of multiples outlet strips (connector bodies), 
cords, and push -in plugs, shall be determined  
Based on those reviews, the technical requirements stipulated in the METI  Ordinance (the Ministry of 
International Trade and Industry ministerial ordinance No.85 1962)  shall be revised.  
 
2. Outline of revision  
【Revision of the technical requirements based on accident cases res ulting from electrical appliances 】 
① Electric vacuum cleaners with over 1kW  
With regard to the technical requirements, the provisions then in force shall remain applicable.  
② LED-lamps  
・LED-lamps  
Considering JIS C 8156(2011) and the technical standards for conventional light sources(incandescent lamps 
and fluorescent lamps), the requirements relating to fail -safe structure, flicker prevention, and so on shall be 
determined.  
・LED-luminaries and oth er light sources using LEDs  
  Considering the technical standards for incandescent lamp lighting fixtures and discharge -lamp lighting fixtures, 
the requirements relating to fail -safe structure, flicker prevention, and so on shall be determined. The similar  
provisions for pedestal lighting fixtures and other conventional electrical products  using LEDs shall be made.  
③ Lithium -ion batteries having special constructions  
The conventional tech nical requirements relating to vibration, b attery enclosure tes t at high ambient temperature, 
free fall, mechanical shock (crash hazard) shall not apply.  
④ Power supply cord set for extension  
From the point of view of degradation prevention and damage prevention of the products, the provisions 
concerning double -insulated c ode and junction strengthening shall be made.
