KEEPING STANDARDS UP TO DATE

Standards are living documents which reflect progress in science, technology and systems. To maintain their currency,

all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued.

Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which

should include any amendments which may have been published since the Standard was purchased.

Detailed information about joint Australian/New Zealand Standards can be found by visiting the Standards webshop at

www.standards.com.au or Standards New Zealands website at www.standards.co.nz.

Alternatively, Standards Australia publishes an annual printed Catalogue with full details of all current Standards.

For more frequent listings or notification of revisions, amendments and withdrawals, Standards Australia and Standards

New Zealand offer a number of update options. For information about these services, users should contact their

respective national Standards organisation.

We also welcome suggestions for improvement in our Standards, and especially encourage readers to notify us

immediately of any apparent inaccuracies or ambiguities. Please address your comments to the Chief Executive of either

Standards Australia or Standards New Zealand at the address shown on the title page.
