This Standard sets out the methods for determining the coefficients of expansion of masonry units, segmental pavers and flags. The coefficients of expansion estimated by these tests represent the total 15 year expansion of either kiln-fresh or non-kiln-fresh fired clay units. Provision is also included for the estimation of past expansion and of residual expansion to 15 years, of units of any age.

This Standard sets out methods of sampling masonry units, segmental pavers and flags for testing of a lot, for the test methods given in AS/NZS 4456.2 to AS/NZS 4456.19 inclusive.

This Standard sets out the method for determining moisture content, dry density and ambient density of masonry units, segmental pavers and flags.

This Standard sets out the method for determining the material thickness and the core volume percentage of masonry units.

This Standard sets out the method for determining the potential of masonry units, segmental pavers and flags to effloresce.

This Standard sets out the method of examination for pitting, due to lime particles, of masonry units, segmental pavers and flags.

This Standard sets out the method for determining the water absorption properties of masonry units, segmental pavers and flags.

This Standard sets out the methods for determining the coefficients of contraction of masonry units, pavers and flags.

This Standard sets out methods for testing masonry units, segmental pavers and flags, to determine their resistance to salt attack.

This Standard sets out the method for determining the lateral modulus of rupture of masonry units.
