To maintain their currency, all S tandards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. S tandards may also be withdrawn. It is important that readers assure themselves they are using a current S tandard, 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 S tandards Web S hop at .au or S tandards New Zealand web site at and looking up the relevant S tandard in the on-line catalogue.Alternatively, both organizations publish an annual printed Catalogue with full details of all current S tandards. For more frequent listings or notification of revisions, amendments and withdrawals, S tandards Australia and S tandards New Zealand offer a number of update options. For information about these services, users should contact their respective national Standards organization.We also welcome suggestions for improvement in our S tandards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities.

It shall also be marked toindicate that the total load connected is not to exceed the rating of the device.Where a lampholder is provided and there is a restriction on the wattage of lamp that maybe inserted, the maximum wattage of the lamp shall be marked. This form of marking shallbe similar to ‘MAXIMUM LAMP RATING ... ... WATTS’.Unless the EPOD is marked with a degree of protection IP33 or greater it shall be marked‘for indoor use’ only.N OTE: Manufacturers who place the number of this Standard on a product or on packaging orpromotional material related to that product, are advised to ensure that there is verificationavailable that the product has been manufactured to comply with this Standard.7.2 Additional marking requirements for EP ODs incorporating a reeling or coilingarrangementThe following additional marking for EPODs incorporating a reeling or coiling arrangementshall be made in durable lettering not less than 3 mm in height and in a colour in contrastwith that of the material of the reeling or coiling enclosure:DO NOT OPERATE UNLESS CORD FULLY UNREELEDThis additional marking shall be on the face or faces adjacent to the socket-outlets.The additional marking requirement does not apply where the design is such that the socket-outlets cannot be energized unless the flexible cord is fully extended or where the test ofClause 8.3 is satisfied when the flexible cord is fully reeled or coiled.7.3 Location of markingThe marking shall be clearly discernible from the outside of the EPOD.
