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Standards may also be withdrawn.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 Web Shop at www.standards.com.au or Standards New

Zealand web site at www.standards.co.nz and looking up the relevant Standard in
the on-line catalogue.
Alternatively, both organizations publish 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 organization.
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 back
cover.

This Standard was issued in draft form for comment as DR 06932.

PREFACE

This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee EL-
001 Wiring Rules. The Standard aims to provide persons who carry out periodic verification, by
inspection and/or testing, with the means to determine, as far as reasonably practicable, whether the
installation and all its constituent equipment is in a safe condition for continued use, and that the
electrical installation complies with safety requirements for the prevention of fire and the protection of
persons and livestock from electric shock.

AS/NZS 3019 may be applied through legislative requirements, made in each State and Territory of
Australia and in New Zealand, concerned with the safety of electrical installations, that require certain
electrical installations to be inspected and tested from time to time. Additionally, verification of an
electrical installation may be requested by the owner/occupier or another organization.

This Standard differs from the previous New Zealand-only edition, NZS 3019:2004, in that three levels
of verification are specified: by basic visual inspection, by visual inspection and limited testing, and by
visual inspection and full testing, rather than the verification of specific types of installations.
Verification of caravans and pleasure craft previously covered will be contained in the new editions of
AS/NZS 3001 and AS/NZS 3004 Part 2 respectively, which are expected to be published in 2008.

Electrical installations — Periodic verification

SECTION 1 SCOPE AND GENERAL

1.1 Scope
This Standard sets out the requirements for periodic verification of existing electrical installations
which are connected to a low voltage a.c. supply system (exceeding 50 V a.c. but not exceeding 1000
V a.c.).

Verification, by inspection and/or testing is intended, as far as reasonably practicable, to determine

whether the installation and all its constituent equipment is in a safe condition for continued use.

NOTE — Inspection and testing to this Standard should provide evidence that the installation complies with the
relevant requirements at the time of construction of the installation.

This Standard does not apply to the periodic verification of the following electrical installations:

(a) Installations designed and constructed to the AS/NZS 3000 provisions relating to specific design
and installation. Refer to the verification specification prepared for the installation as required by
AS/NZS 3000;

(b) Installations of the following types:

(i) Relocatable installations and their site installations. Refer to AS/NZS 3001
(ii) Marinas and pleasure craft installations. Refer to AS/NZS 3004
(iii) Hazardous areas. Refer to AS/NZS 2381.1 and AS/NZS 61241 series
(iv) Electro-medical areas. Refer to AS/NZS 3003, and in New Zealand only, the provisions of
NZS 3003.1
(v) Shows and carnivals installations. Refer to AS/NZS 3002
(vi) Construction and demolition sites. Refer to AS/NZS 3012

In New Zealand it does not apply to:

(c) Electrical installations and equipment which operate at non standard voltages and frequencies.
Refer NZS 6114;

(d) Mobile electro-medical relocatable installations. Refer NZS 6115; and

(e) Areas of electrical installations where electrical animal stunning or meat conditioning occurs.
Refer to NZS 6116.

NOTE — Periodic testing of appliances is covered by AS/NZS 3760.

1.2 Types of verification covered

This Standard provides for verification by:

(a) Basic visual inspection;

(b) Visual inspection and limited testing; and

(c) Visual inspection and full testing.
