DR AS/NZS 4234:2020 (Committee CS-028 Solar Water Heaters )
Heated water systems - Calculation of energy consumption
The objective of this Standard is to provide methodologies to quantify the energy consumption of heated liquid systems and calculate energy savings relative to reference heaters. The performance evaluation procedure defined in this Standard has been designed to provide a means of evaluating the annual task performance of heated water systems. Testing of solar and heat pump water heating systems under outdoor conditions is defined in AS 2984, Solar water heaters—Methods of test for thermal performance—Outdoor test method. Outdoor testing requires a long test period (8–10 weeks) due to the need to obtain stable inputs for a range of operating conditions. The major drawback of outdoor testing is that the tests must be repeated for every variation of system configuration offered by the supplier. The procedure defined in this Standard overcomes the time and cost limitations of using the outdoor test standard AS 2984. The performance evaluations are based on modelling annual performance in a range of climatic conditions using a simulation program. Performance criteria are specified for simulation programs that can be used to implement the requirements of this standard. The climate data files for the five climate zones in Australia are supplied free of charge to users of the standard by Exemplary Energy Partners. For users of the standard wishing to use climate data for other sites, additional climate data can be purchased from www .exemplary .com .au/ solar climate data/ solar -radiation -data .php This Standard utilizes technologies such as Solar Thermal Collectors, Heat pumps, Photovoltaic arrays, Thermal Storage Tanks (which can incorporate integral gas or electric resistance element boosting) and in line supplementary heating utilizing gas or electric energy sources.

DR AS/NZS 3002:2020 (Committee EL-001 Wiring Rules)
Electrical installations - Shows and carnival events
This edition was prepared to update requirements for the use of electricity for lighting and power in concessions, stands, tents, booths and other show and carnival event structures and areas associated with shows, carnivals and the like in conjunction with the issue of AS/NZS 3000:2018. It is to be noted that some States have legislation that calls up additional requirements to those contained in this Standard. This Standard differs from AS/NZS 3002:2008 in several areas including the following: (a) The structure of this Standard is similar to AS/NZS 3000 with respect to the flow of information contained within. (b) Show and carnival events, public events and limited domestic events are encompassed. (c) Section 2 provides requirements for electrical installation wiring. (d) Section 3 provides requirements for event wiring, equipment and appliances that are present during the event only. (e) There is an emphasis on electrical safety at show and carnival events. (f) A number of appendices from AS/NZS 3000:2018 are provided as reference material. This Standard may be applied through legislative requirement, from a date to be set by the relevant regulatory authority. If work on an installation was commenced before publication of this edition, refer to the relevant authority regarding permission for the installation to be completed under AS/NZS 3002:2008 as applicable.

DR AS/NZS 3500.4:2020 (Committee WS-014 Plumbing and drainage)
Plumbing and drainage, Part 4: Heated water services
The objective of this document is to provide heated water solutions for compliance with: a. The National Construction Code (NCC) Volume Three, Plumbing Code of Australia (PCA); and b. The New Zealand Building Code (NZBC), Clause G12 Water Supplies. A list of all parts in the AS/NZS 3500 series for plumbing and drainage can be found in the Standards Australia and Standards New Zealand online catalogues. The major changes in this revision are as follows: i. Conformance to individual product standards has been removed. All products used in plumbing and drainage systems in Australia need to be WaterMarked and in New Zealand need to comply with the relevant requirements of the New Zealand Building Code. See Appendix B for further information. Removal of specific product standard conformance requirements avoids inconsistencies and contradictions between this document and the PCA and NZBC. ii. Definitions have been relocated to AS/NZS 3500.0 for consistency across the series. iii. Jointing requirements for plastics pipes have been clarified and expanded to allow different methods. iv. Changes to the requirements for the marking of pipes in commercial buildings to assist in the better identification of pipework and avoid cross connections. v. Changes to the requirements for the installation of water services located in metal-framed walls to bring the provisions in line with those of the National Association of Steel-Frames Housing (NASH). vi. The separation between above-ground heated water services pipe work and electrical services has been reduced to bring it in line with AS/NZS 3000 and AS/NZS 3500.1 vii. To improve the amenity of users and reduce wastage of water and energy, changes have been made to requirements for circulated heated water systems including water meters and entry points for heated water, thermal insulation for non-circulatory heated water piping, and maximum capacities of any dead leg from the branch offtake to its termination. Appendix Q has been added to provide a guide to determining capacity of dead legs and estimating wait times. Heated water temperature control provisions, which are considered matters of public policy, were elevated from AS/NZS 3500.4 to the PCA Part B2 Heated Water Systems. To avoid conflict between the PCA and this document, clauses relating to sanitary fixtures delivery temperature and solutions for control of delivery temperatures have been deleted.

DR AS/NZS 2299.2:2020 (Committee SF-017 Occupational Diving)
Occupational diving operations, Part 2: Scientific diving
The objective of this Standard is to provide the scientific diving sector with a set of minimum requirements for uniformity of practice in relation to the health and safety of those people engaged in occupational underwater operations for the purpose of scientific diving. Risk assessment may indicate a need to utilize an alternative standard. Significant differences from the previous edition include the following: a. Minimum competencies, training and certification for scientific divers has been removed from Appendix A and added to AS 2815.6 which is specific to scientific diver training competencies. b. Diver categories have been updated and consider regulatory requirements. c. Modernization in terminology in both diving procedures and work health and safety. d. Revision of worksite chambers, breathing gas quality, the introduction of a maximum partial pressure of oxygen, and calibration of pressure gauges. e. Addition of specific requirements for enriched air nitrox (EAN) diving, which includes – i.equipment requirements; ii.breathing gas supplies for SCUBA and SSBA; and iii.EAN procedures. f. Revision of medical requirements. g. Addition of an appendix for diving medical examination forms. h. Removal of reference to specific decompression tables for diving.

DR SA/SNZ TR ISO 19167:2020 (Committee IT-004 Geographical Information/Geomatics)
Application of ubiquitous public access to-geographic information to an air quality information service
The objective of this document is to facilitate an understanding of the Ubiquitous Public Access (UPA) context information model, as defined in AS ISO 19154, to establish a UPA-to-Geographic Information (GI) environment. In addition, this document illustrates how the UPA context information model is designed and implemented to provide an air quality information service from a geographic information system (GIS)-based air quality information system. The UPA context information model for air quality information is only a sample of all possible examples to realize the UPA-to-GI that could satisfy the requirements of AS ISO 19154. This document is identical with, and has been reproduced from, ISO/TR 19167:2019, Application of ubiquitous public access to-geographic information to an air quality information service.
