AS 4055:2021 is amended as follows. The amendments should be inserted in the locations as instructed.

Sets out a classification scheme for wiring systems according to their resistance to the hazards of fire and mechanical damage.

Sets out requirements and guidelines for the long term type testing, glazing, periodic manufacturing testing and other associated aspects to do with insulating glass units.

Sets out the quality requirements for cut sizes of flat, transparent, clear ordinary annealed, tinted heat-absorbing, patterned and wired glass for general glazing and/or further processing.

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.

Sets out a hot smoke test methodology by means of which a specified quantity of smoke may be generated, at a safe temperature, within a building.

Outlines a performance-based approach to the maintenance of cooling water systems with respect to the control of microorganisms, including Legionellae, within such systems. This approach combines automatically regulated water treatment with monitoring, assessment and control strategies to help create a low risk environment within the cooling water system.

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 requirements for the performance and construction of air filters for use in general ventilation and airconditioning systems. It classifies air filters on the basis of design, construction performance and application and establishes minimum criteria for acceptance of an air filter into a particular category. It does not apply to HEPA filters.

Specifies the classification of smoke-spill fans, and the laboratory test methods and procedures used to rate their performance (and that of their motors). Fans are rated in terms of their suitability to operate continuously without significant loss of performance, for a specified time at a specified air temperature. This Standard deals only with laboratory type-testing and does not consider the testing of smoke-spill fans after they have been installed in a building.
