Specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment, and establishes procedures for the operation, maintenance, and repair of refrigerating systems and the recovery of refrigerants.

This Standard provides an unambiguous system for assigning designations to refrigerants. It also establishes a system for assigning a safety classification to refrigerants based on toxicity and flammability data, and provides a means of determining the refrigerant concentration limit.

Specifies a simple means of referring to common refrigerants instead of using the chemical name, formula, or trade name. It also establishes a uniform system to be used in assigning the proper reference number and classification to refrigerants; the system for refrigerant classification is defined and physical data of common refrigerants listed.

Specifies requirements for safety and environmental aspects in relation to operation, maintenance and repair of refrigerating systems and the recovery, reuse and disposal of all types of refrigerant, refrigerant oil, heat transfer fluid, refrigerating system and part thereof.

Applicable to the design, construction, and installation of refrigerating systems, including piping, components, materials, and ancillary equipment directly associated with such systems.

AS 4421:2023 specifies the minimum requirements for the operation and management of an organization providing protective security services.

Sets out requirements and safety principles relating to the design, installation, and operation of industrial appliances that involve the combustion of gas or liquid fuel, or other fuel in air suspension, or the generation of combustible vapours in such appliances.

This Standard specifies a method for the determination of the thickness loss of textile floor coverings under dynamic loading. It is applicable to all types of textile floor coverings with a surface that is level in height and construction. It does not apply to other textile floor coverings unless the areas of different thickness or construction can be tested separately.

This Standard describes a method for determining the strength of the bond between the backing components of a textile floor covering which can be peeled apart. This method is applicable to tufted carpets which have primary and secondary backing materials forming a bonded composite substrate.

This Standard specifies a method for the determination of the thickness of pile above the substrate of a textile floor covering. It is applicable to all textile floor coverings with pile capable of being shorn from the substrate, but not to textile floor coverings of varying pile thickness or density, unless the areas can be measured separately.
