**Formulation of committee draft standards (CDs)**

**Circulation of draft standards for comments**

**Formulation of final draft standards**

**Approval and publication of TCVNs*** *

**Using the technical committee  method for TCVN development process.**

**Secretaries of technical committees and subcommittees are staffs of VSC.**

**by any persons or organizations**

**by STAMEQ**

**Technical Committees or Subcommittees**

**MOSTE**

## Electrical product standards

**Process of revision to existing standards**
**The steps are the same as process of developing new standards.**
**Regularly, making revision every 5 years. However, it may arise at any time.**
**The time for process of v\revision may be shorter.**
**The revised standards become effective immediatly, except man datary standards **
**   ****(after 6 months from issued date)**

## Electrical product standards

**Work principle:**** *****Consensus***
**Member of Technical committee:**
***- ******Ministry***
***- Chairman***
***- Secretary***
***- Institute***
***- Consumer / user***
***- Companies (manufacturers,distributors, importers******, ...)***

**Technical committee works**
