Review of Australian Standards. To keep abreast of progress in industry, Australian Standards are subject to periodic review and are kept up to date by the issue of amendments or new editi ons as necessary. It is important therefore that Standards users ensure that they are in possession of the latest edition, and any amendments thereto. Full details of all Australian Standards and related publications will be found in the Standards Australia Catalogue of Publi cations; this information is supplemented each month by the magazine The Australian Standard, which subscribing members receive, and which gives details of new publications, new editi ons and amendments, and of wit hdrawn Standards. Suggestions for improvements to Australi an Standards, addressed to the head off ice of Standards Australi a, are welcomed. Notificati on of any inaccuracy or ambiguit y found in an Australian Standard should be made without delay in order that the matter may be investigated and appropriate acti on taken.
Copyri ght STANDARDS AUSTRALIA Users of Standards are reminded that copyri ght subsists in all Standards Austr alia publi cati ons and software. Except where the Copyri ght Act all ows and except where provided for below no publications or software produced by Standards Australi a may be reproduced, stored in a retr ieval system in any form or transmitt ed by any means without prior permission in writ ing from Standards Australi a. Permission may be conditi onal on an appropriate royalt y payment. Requests for permission and informati on on commercial soft ware royalti es should be dir ected to the head off ice of Standards Australi a. Standards Austr alia will permit up to 10 percent of the technical content pages of a Standard to be copied for use exclusively in-house by purchasers of the Standard wit hout payment of a royalty or advice to Standards Austr alia. Standards Austr alia wil l also permit the inclusion of its copyri ght materi al in computer software programs for no royalty payment provided such programs are used exclusively in-house by the creators of the programs. Care should be taken to ensure that materi al used is from the current edit ion of the Standard and that it is updated whenever the Standard is amended or revised. The number and date of the Standard should therefore be clearly identif ied. The use of materi al in print form or in computer software programs to be used commercially, with or without payment, or in commercial contracts is subject to the payment of a royalty. This policy may be vari ed by Standards Austr alia at any ti me.

This Standard was prepared by the Joint Standards Australia / Standards New Zealand Committee EL/5 on Secondary Batteries to supersede AS 3731.2 1989, Stationary batteries Nickel-cadmium , Part 2: Sealed type. This Standard is the result of a consensus among representatives on the Joint Committee to produce it as an Australian Standard. This Standard is identical with and has been reproduced from IEC 622:1988, Sealed nickel-cadmium prismatic rechargeable single cells, including Amendment No. 2:1992 (which includes Amendment No. 1) and a Corrigendum of August 1992. The Corrigendum and Amendment are bound at the end of this Standard. The text affected by the Amendment is marked in the source document by double marginal bars.
The objective of this Standard is to provide users of valve-regulated nickel-cadmium batteries with specifications covering their construction and performance. Statements expressed in mandatory terms in Notes to tables and figures are deemed to be requirements of this Standard. This Standard is Part 2 of the following series: AS 3731 3731.1 3731.2 (a) (b) (c) Stationary batteries Nickel-cadmium Part 1: Vented type Part 2: Valve-regulated type (this Standard)
For the purposes of this Australian Standard the source text should be modified as follows: The words this Australian Standard should replace this International Standard wherever they appear. A full point (.) substitutes for a comma (,) when appearing as a decimal marker. The references to international Standards should be replaced by references to the following equivalent Australian or Joint Australian/New Zealand Standards: Australian or Joint Australian/New Zealand Standard AS 1042 Direct-acting indicating electrical measuring instruments and their accessories

This is a free 6 page sample. Access the full version at http://infostore.saiglobal.com. Note. In this context prismati c refers to cell s having rectangular sides and base.
1.2 Definitions For the purpose of this standard, the following definitions apply. 1.2.1 Sealed cell A cell which remains closed and does not release either gas or liquid when operated within the limits of charge and temperature specified by the manufacturer. The cell may be equipped with a safety device to prevent dangerously high internal pressure. The cell does not require addition to the electrolyte and is designed to operate during its life in its original sealed state. 1.2.2 Nominal voltage The nominal voltage of a single sealed nickel-cadmium prismatic rechargeable cell is 1.2 V. 1.2.3 Rated capacity The quantity of electricity C 5 in Ah (ampere hours) declared by the manufacturer which a single cell can deliver at the 5 h discharge rate to a final voltage of 1.0 V at 20C after charging, storing and discharging under the conditions specified in Section Four. 1.3 Measuring instruments The measuring instruments used for the tests shall be selected to meet the magnitude of the parameters to be measured. Equipment shall be regularly calibrated to ensure that it shall at all times have the degree of accuracy given below. 1.3.1 Voltage measurement The instruments used for voltage measurement shall be voltmeters having an accuracy class of 0.5 or better as defined in IEC Publication 51 for analogue instruments and IEC Publication 485 for digital instruments. The resistance of voltmeters shall be at least 1000 /V.
