1. About JEITA Standards
The format of JEITA Standards is based on the "Regulations about Standards" prepared by the Japan Electronics and Information Technology Industries Association (JEITA). This format conforms to JIS Z 8301 (Form of Standards Table), and standards and technology papers are prepared based on TSC-16 (Creation Standards for Standards of JEITA).
JEITA's policy is to review and rapidly confirm the appropriateness of standards and technical reports, and to revise or abolish them as deemed necessary, at a maximum of five years after their establishment. In other words, all JEITA standards and technical reports are reviewed at least every five years.
There are three categories of results to these reviews of JEITA standards and technical reports fall into three categories: (1) Revisions: when technological developments and/or other factors bring the contents of standards and technical reports out of sync with current conditions; (2) Abolishment: when standards and technology papers become meaningless, when their contents are integrated or subdivided as the result of a reorganization or unification of standards systems, and when it is deemed sufficient to adopt international, JIS or other organizations' standards; and (3) Confirmation: when it is deemed that there is no need for either revision of abolishment.
The term of validity of standards and technical reports, from the date of establishment and including the date of the five-year review, is 10 years. When there is no confirmation of a standard or technology paper within five years, it is abolished.
2. About the Classification of Standards
JEITA standards are classified into "Standard", "Provisional Standard" and "Technical Report".
3. About Standard Numbers
The numbers assigned to JEITA standards are arranged as follows:
Example: JEITA **-2001A
- Item 1
This item is "JEITA", signifying the Japan Electronics and Information Technology Industries Association".
- Item 2
Abbreviations (two capitalized letters) are assigned primarily to indicate product types, as follows:
ET General electronics industry CP Consumer electronics product
TT Information and communications equipment AE Applied electronics equipment
RC Electronic components ED Electronic devices
EM Electronics materials IT Information processing
This symbol indicates the classification of the document. In the case of standards, a hyphen (-) is used. Provisional Standards are indicated by "X-", and Technical Reports are indicated by "R-".
- Item 4
This item, set as a four-digit number from 0001 to 9999 to differentiate it from the classification symbol, is determined by the product type in Item 2.
- Item 5
This letter indicates that a standard or technical paper has been revised, and is not included in numbers for newly established standards. The revision status of standards and technical papers is indicated by alphabetical letters, starting with "A". However, the letters "I", "O" and "Q" are not used. The final item is not changed in the case of standards and technical papers that have been confirmed as valid after review.
Note: In principle, the abbreviation "JEITA" is used for Item 1 of standards revised from previous formats. However, in the following cases, the previous abbreviation may be used in place of "JEITA":
||When establishing revisions and revision objectives for standards and technical papers with the same "product category", "product type", or "product name"
||When there is the possibility that changing the abbreviation will cause confusion among users
||When the possibility exists that changing the method of abbreviation for standards and technical papers of the same "product category", "product type", or "product name" will damage the continuity of standards and technical papers, and cause confusion among users
4. How to Read the Table of Standards
- Order of publishing
Some product types are mixed together because standards have been published for each area of responsibility since the new Standardization Committee of EIAJ was reorganized in 1995.
- Enactment/Revision column
The row shows the year the standard was enacted or revised.
- Remarks column
The numbers of old standards (enacted before March 1988) are indicated here. These old standards are not available. If an English version of a standard is available, this fact is indicated here.
