CHANGE REQUEST |
Request identity number: |
C00249 |
Applies to: |
S01897 |
Type of request: |
Technically new |
Request status level: |
Resolved |
Proposal: |
Introduce a new symbol for product: 3 phases and 1 phase socket outlet
|
Reason: |
In IEC 60617 DB there are several standardized graphical symbols for installation diagrams for representing product power outlets and telecommunication socket outlets. But there is no symbol for the kind of product which has different outlets for example 3 phase and 1 phase outputs. These kind of components which have multiple different type of outlets are often used in building and industrial installations.
During the preparation of this proposal MT 60617 was consulted.
FI NC propose to standardize a symbol for 3 phase and 1 phase socket outlet

Comments at evaluation: |
DE(RESC): The national committee of Germany once again wants to point out that combinations of existing and well known symbols are not spirit and purpose of standardization work in the IEC! If specified groups of users have a need for a collection of such combined symbols this should be handled for example in a library of the relevant CAD- system (as we use to do it in Germany), or be clearly marked in the DB as "EXAMPLE". We discussed these since the first steps in the 60617 database in 1998. In Germany this also harmonized with the relevant product committees.
JP(HIKE): The Japanese National Committee of TC 3 has no comment, because the proposed graphical symbol is irrelevant to the power supply system in Japan.
FI(ARSI): FI NC support this change request with normal database procedure.
In responce DE NC comment:
Motivation to standardize new graphical symbols in IEC 60617
1.To help users of product standards and system standards to comply documentation requirements.
2.By standardizing symbol then it has designation so it can be refer by using symbol ID.
3.To reach common understanding (language independent) for the meaning of graphical symbol.
If users of IEC 60617 can’t find suitable graphical symbol for diagram then:
1. Users have difficulties to comply requirements for product standards.
2. CAD symbols libraries are extended independently without coordination. Coordination is important because there are more than 6000 standardized graphical symbols in: IEC 60617, IEC 60417, ISO 14617, ISO 7000 and ISO 7010.
3. Designers start to use of mixed standardized and non-standardized graphical symbols which makes difficulties for with different interpretation in global market (design from country A, installers from country B, project implemented and maintained in country C).
4. Language independency is lost because without good knowledge of IEC 81714 series it is tempting to use letter codes as part of graphical symbol (abbreviation of word on local language are commonly used).
5. Local unofficial graphical symbol collections start to become de facto which creates commercial boundaries.
Some examples of product standards which require use graphical symbols standardized in IEC 60617
IEC TC 44
IEC 60204-1 Ed. 5.0 Safety of machinery - Electrical equipment of machines
Clause 17.6 Circuit diagrams
“Any graphical symbol not shown in IEC 60617 shall be separately shown and described on diagrams or supporting documents.”
IEC TC 64
IEC 60364-5-51 Ed. 5.0 Electrical installation of buildings - Part 5-51 Selection and erection of electrical equipment - Common rules
Clause 514.5.2 Diagrams
“The symbols used shall be chosen from IEC 60617 series.”
DK (KATH): The Danish NC supports the proposal for normal database procedure.
CN(GUTI): CN NC support the proposal. Normal database procedure.
SE (PASV): SE NC supports this change request with normal database procedure.
-------------------------------------------------
Secretary comment: the evaluation was closed with 4 votes for normal data base procedur, one against and one abstain, but the CR will be discussed in MT 60617 before validation.
NO(ES): The evaluation shall not be terminated before the evaluation ends. The evaluation ends today, 2012-01-30.
We do support the change request, normal procedure
-------------------------------------------------
Secretary comment: The comment from NO NC was considered by MT 60617. As recommended by MT 60617 and a majority of VT 60617 the Change request will go to validation
------------------------------------------------- |
Comments at validation: |
Secretary comment: The validation was closed with 6 NCs voting in favour of symbol S01897 and one NC abstain.
The symbol will be released as standard |
Voting at validation: |
JP(HIKE): JNC votes ABSTENTION because of no applicablility in Japan.
SE(PASV): SE NC votes YES.
FI(ARSI): FI NC votes YES.
AT (WGAS): AT NC votes Yes
DK(KATH): DK NC votes YES
FR(LROG):FR NC votes YES and proposes the following French translation "socle de prise de courant 3 phases et 1 phase" for "3 phase and 1 phase socket outlet".
DE (RESC): DE NC votes NO |
