4、ittee Testing interests Review of Standards.To keep abreast of progress in industry, Joint Australian/ New Zealand Standards are subject to periodic review and are kept up to date by the issue of amendments or new editions as necessary. It is important therefore that Standards users ensure that they

5、 are in possession of the latest edition, and any amendments thereto. Full details of all Joint Standards and related publications will be found in the Standards Australia and Standards New Zealand Catalogue of Publications; this information is supplemented each month by the magazines The Australian

6、 Standard and Standards New Zealand, which subscribing members receive, and which give details of new publications, new editions and amendments, and of withdrawn Standards. Suggestions for improvements to Joint Standards, addressed to the head office of either Standards Australia or Standards New Ze

7、aland, are welcomed. Notification of any inaccuracy or ambiguity found in a Joint Australian/New Zealand Standard should be made without delay in order that the matter may be investigated and appropriate action taken.

32、C to 35C and a relative humidity of 45 percent to 75 percent. Before measurements are made, the specimens shall be preconditioned under these atmospheric conditions for a period of at least 30 min. The specimen shall be removed from the packaging in such a way that it will not be subjected to tensio
