Provides a laboratory method of measurement the airborne sound insulation of a suspended ceiling with a plenum of defined height mounted above an acoustical barrier which separates two rooms of a specified test facility. This Standard has been adopted with national modifications and reproduced from ISO 140-9:1985.

Sets out requirements for electrical installations which supply electricity to equipment on construction and demolition sites. Includes requirements for the inspection and testing of electrical equipment used on building construction sites.

Specifies requirements for cold-formed steel hollow sections for structural purposes, for the nine grades electric arc-welded, cold-formed structural steel hollow sections.

Specifies a spectrophotometric method for the determination of aluminium content in the range of 0.002 percent to 1.4 percent aluminium in all types of iron and steel. The method uses a mercury cathode, followed by solvent extraction to separate interfering elements, with alizarin red S to produce a chromogen which is measured at a wavelength of 490 nm.

The objective of this Standard is to define the conceptual schema for the description of referencing by coordinates.

AS/NZS ISO 50001:2021 identically adopts ISO 50001:2018 which specifies requirements for establishing, implementing, maintaining and improving an energy management system (EnMS). The intended outcome is to enable an organization to follow a systematic approach in achieving continual improvement of energy performance and the EnMS.

Specifies requirements for wrought aluminium and aluminium alloy drawn tube for general engineering purposes. Chemical composition and tensile properties are specified, and allowable tolerances on dimensions included. Included are two appendices, one provides guidelines on information to be supplied by the purchaser at the time of enquiry or order, the other lists fabrication characteristics and application data.

Adopts IECTR61439-0, Ed. 2.0 (2013) to provide the user with guidance on the specification that should be provided in order to achieve the desired design of a low-voltage switchgear and controlgear assembly.

Specifies structural property, marking and physical requirements for mechanically stress-graded timber. Physical requirements are given for strength considerations as well as for utility considerations.

This Standard sets out the requirements for fly ash for use as a cementitious material in concrete, mortar and related applications.
