The Standards Act 1965—Draft Amendment to New Zealand
Standard Specification Available for Comment

Number and Description of Draft
DZ 1524/A1 Draft Amendment No. 1 to NZS 1524:1962 Specification for electric shaver supply units. Gratis

This draft amendment metricates measurements, makes minor marking modifications, removes some of the differences between this Standard and AS 3194:1982, and updates references.

All persons who may be affected by this amendment and who desire to comment thereon, may obtain copies from the Standards Association of New Zealand, Wellington Trade Centre, 181–187 Victoria Street (formerly known as 15–23 Sturdee Street) (or Private Bag), Wellington.

The closing date for the receipt of comment is 30 August 1986.

Available for Comment

Number and Title of Specification
DZ 198/A3 Draft Amendment No. 3 to NZS 198:1967 3-pin flat-pin plugs, plug sockets, tap-ons and cord extension sockets with 10-ampere, 250-volt (maximum) rating. Gratis.

This draft amendment is issued as an interim updating measure pending the preparation of a full revision. (The draft revision DZ 6209 circulated in November 1982 has since been deferred to allow further development of new safety features in co-operation with the Standards Association of Australia in their revision of AS 3112:1981). This draft amendment will establish closer alignment with the current edition of AS 3112, mainly in respect of dimensions and tolerances, and will therefore remove some of the impediments to trans-Tasman trade. Another feature is the proposal to abolish the distinction between “light duty” and “heavy duty” accessories by requiring all models to have the full cord-anchorage provision. Provision is also added for cord-extension sockets to be moulded on to a 10-ampere cord.

Metrication is a mixture of soft and hard conversions. Some dimensions or tolerances have been altered in order to align more closely with AS 3112 (and DZ 6209), or at least to eliminate conflict by allowing an overlap. These cases may be recognised (in figs. 1 to 4) by an entry under “Equivalent”, showing where the new metric value to be substituted differs from the old value being deleted.

DZ 2147/A2 Draft Amendment No. 2 to NZS 2147:1967 2-pin flat-pin moulded-on plugs with 10-ampere, 250-volt (maximum) rating, for use in 3-pin sockets. Gratis.

Details as above but for figs. 1 to 4 refer to figs. 1 and 2. (The full revision will combine NZS 2147 and NZS 198).

The Standards Act 1965—Draft New Zealand Amendment
Available for Comment

Number and Title of Specification
DZ 3122/A2 Draft Amendment No. 2 to NZS 3122:1974 Specification for Portland cement (ordinary, rapid hardening and modified). $10.00

The inherent deficiencies of NZS 3122:1974 as an effective working document are well recognised by cement producers and major cement users alike. Amendment No. 2:1986 does not seek to remedy all of these deficiencies. Its release is an interim measure pending a full revision in the relatively near future.

For the most part Amendment No. 2 addresses editorial shortcomings and other anomalies which render the original specification either inoperative or unduly onerous in the light of current circumstances. With a view to what might follow, Amendment No. 2 also embodies innovative changes, such as the removal of Type M (Modified) cement and the introduction of two would-be replacements in the “special” cement category: Type LH (Low Heat) and Type SR (Sulphate Resisting). The SANZ Amendment No. 2 Committee was of the opinion that the hybrid character of the Type M specification (part low heat and part sulphate resisting) was incompatible with its performing either role in a satisfactory manner.

Another notable feature of Amendment No. 2 is the introduction of a standard sand for the determination of cement strength via the preparation and testing of concrete cylinders. It is thus hoped to reduce the variations in the use of sands having different material characteristics.
