Procedures for amending or correcting the TTC Standards

1. Determining the need for correction or amendment 
      The corrections referred to here concern descriptive errors that are typographical or grammatical in nature, or technical changes that are mere changes or modifications fully within the scope of the standards in question. Dealing with any additional new function (i.e., inclusion of a new international trend toward standardizing additional specific items) is considered outside the scope of the corrections mentioned above. The latter case of addressing such new functional addition is called a "amendment".
      Whether there is a need for such a correction or amendment should be determined by the Technical Subcommittee under which the Working Group concerned with the TTC standards in question operates. The deliberations are coordinated by the Co-ordination Committee.
      Any items considered to be outside the scope of a correction by the Technical Subcommittee or Coordination Committee are subject to the established procedures for TTC standard preparation.
   

    

2. Correction and amendment procedures
      Exhibit 1 shows the flow of the correction and amendment procedures. When members submit a request for a correction or amendment, they should specify in writing (in any appropriate format): (1) the names of those proposing the correction or amendment, (2) the items or descriptions to be corrected or amended, and (3) the reasons for making such a correction or amendment. Then one of the following two steps should be taken. 
   

   (a) A member whose representative is on the Working Group belonging to the Technical Subcommittee dealing with the applicable TTC standard document should submit the proposal through his representative to the chairman of that Technical Subcommittee. 
   

   (b) Any other member or nonmember should submit the proposal to the chairman of Technical Assembly through the secretariat. 
   

    

3. How to make known the corrected contents 
      The details of how to distribute the corrected contents to those concerned are listed in Exhibit 1. Below is an outline of the procedures involved. 
      The results of the deliberations by the Technical Subcommittee and of a coordination by the Coordination Committee should be put in Errata. The errata, signed by the chairman of the Technical Assembly and by the chairman of the Technical Subcommittee, should be sent to all Technical Assembly members. The Errata should include concrete reasons why each particular correction was made. 
   

      The corrected contents should be treated in the following manner in connection with the periodical "TTC Report" and with the TTC standard documents already sent to the members.

   (1) The Errata is to be included in the periodical "TTC Report" (issued bimonthly). 
   

   (2) Copies of the Errata are to be sent to the Technical Assembly members who have already received the TTC standard documents. 
   

      When the corrected contents are made known to those concerned, the version of the standard documents before the correction should be specified. The contents of the Errata prepared by the Technical Subcommittee and the Coordination Committee should be approved "after the fact" at the first Technical Assembly meeting to be held after the correction. 
   

    

4. Control over TTC Standard document correction
      Corrections should be made in units of the groups shown below. Exhibit 2 shows concrete ways to control the correction procedures. The correction groups are : 
   

   (1) Each standard (JTs, etc.) 
   

   (2) TTC standard documents (by volume)
