What is the examination ?

@After The WWII, The quality of Japanese radio set was very poor.
The ministry of Posts and Telecommunications enforced type examination on the radio manufacturers.
The date of enforcement was 01/04/1948.
However, 20 test sample set from main radio manufacturers were all failed.
The date of enforcement changed into 01/07/1948.
And the test standard was lighten.
The test result under the lighten standard, passed set was only 60% of all.

Unbelievable result, but this was actuality in Japan at that time.
The radio set that shipped from 01/02 to 30/04/1948 was not applicable.

The ministry of Posts and Telecommunications granted passed number to passed radio set from No.1.
All types of radio sets except made by amateur were the objects of this examination.
From 05/1948 to 11/1949, 289 radios, radio phonograph, and amplifier with radio was given passed number.
This system was abolished by the revision of the broadcasting low.

@According to the first plan, The notification and advertisement of passing the examination was prohibited.
On the executed system, to avoid the set without examination, The manufacturers were obligated to indicated passed number on the set and advertisement.
The design of the mark was left to the manufacturers.


Advertisement included passed number (Hayakawa Electric Industry Co., Ltd. 10/1948)

The passed radios were not all radios on the market.
Many small or local manufacturerfs radio set (include portable set) may not be took the examination.
