Thank your Dieter and Thomas,

The tradition in SC 2/WG 2 is to have a separate number series. At the Minden meeting we reached N229 for the minutes. SC 2 picked up some items from the Wg 2 minutes and issued the following SC 2 resolutions:

　

Resolution 5/2002　AWI 20283 on Vibratory Acceleration

Measurements for Shipboard Equipment

ISO/TC 108/SC 2 decides to change the work item AWI 20283 into a multi-part

document with the following provisional parts :

Part 1 General ...

Part 2 Mechanical vibration - Guide for the measurement, evaluation, and reporting of global structural vibration in merchant ships

Part 3 Mechanical vibration - Vibratory Acceleration measurements and acceptance criteria of shipboard equipment

Part 4 Mechanical Vibration - Guidelines for the Measurement and Evaluation of Ship Propulsion Machinery Vibration

Part 5 (future revision of ISO 6954:2001)

and to register parts 1, 2 and 4 as preliminary work items (PWI).

A first CD for part 3 will be circulated to SC 2 members for comments by end of November 2002.

A draft for part 1 is expected by end of November 2002 for circulation as new work item proposal (NP).

A draft for part 4 is expected by end of January 2003 for circulation as NP.

　

Resolution 11/2002　NP on Amendment to ISO 10326-1:1992

Provided that the result of voting on NP Amendment to ISO 10326-1 :1992 (doc 108/2 N 376) will be positive, ISO/TC 108/SC 2 agrees that the WI will be developed in CEN/TC 231 (WG 9) in parallel with ISO. The group should be open for experts nominated by SC 2 and SC 4 members.

　

Resolution 12/2002　PWI on Human Subjective Assessment of

Vibration and Noise Onboard Ships

ISO/TC 108/SC 2 decides to confirm the Croatian request to revive of the WI together with human assessment to establish confidence in the guidelines of ISO 6954. The common procedure for data collecting will be reviewed and adopted through the WI for establishing environmental guidelines according to new measuring procedures in ISO 6954.

　

Arthur Kilkullen recently sent us the revised version of document N222

Global structural vibration. This document shall from now on be referred to as ISO 20283-2 and in the case it is circulated to the Wg 2 before it is sent to the secretariat for SC 2 circulation then it will have a new Wg 2 number. This N222 document will be followed by N 223 ... propulsion machinery vibration from now on ISO 20283-4 and N 228　Vibratory acceleration of shipboard equipment, ISO 20283-3.

There is still no ISO 20283-1. You have to think something out Helge.

Thanks again for reminding me.

Best Regards.

Alf Olsson
