Identically adopts EN 81 21:2018, specifying safety rules related to new passenger and goods/passenger lifts permanently installed in existing buildings where in some circumstances due to limitations enforced by building constraints, some requirements of EN 81 20:2014 cannot be met. Covers constraints and gives requirements for alternative solutions. Intended to be read and applied in conjunction with EN 81 20:2014.

The objective of this Standard is to establish a method for the quantitative determination of the particle size distribution in a soil using an hydrometer.

Provides design charts for the flow of liquid through pipes and fittings based upon surface roughness, diameter, velocity and hydraulic gradient. The resistance coefficients of fittings are also included.

Sets out the method for testing aggregate or rock for resistance to wear using the Deval attrition machine, and for measuring the attrition value of freshly crushed rock.

This Standard sets out the method for the determination of the fine particle size distribution in road materials.

Nominates a series of test procedures and limits to be utilised in different geographic areas of Australia. These procedures and limits have proved suitable for specifying aggregates for use in asphalts in pavements up to and including major highways.

The objective of this Standard is to set out minimum requirements and recommendations for the provision of on-street parking.

Provides general requirements for the execution, testing, supervision, monitoring and installation methods of prefabricated vertical drain projects. It also includes information on design considerations, and practical and design aspects of vertical drainage.

This Standard specifies requirements and procedures for the installation of square carpet tiles.

Specifies requirements for aluminium ingots and aluminium alloy ingots and castings. Includes tables listing the chemical composition of aluminium alloys and the machanical property requirements of test bars. Appendices describe the designation system for alloys and tempers and provide guidance on the selection of alloys.
