AS/NZS 2699 Built-in components for masonry construction
2699.1 Part 1: Wall ties
2699.2 Part 2: Connectors and accessories
2699.3 Part 3: Lintels and shelf angles (durability requirements)

The objective of this Standard is to provide manufacturers with requirements for the classification of wall ties into three duty ratings. Type A cavity wall ties and veneer wall ties are classified according to characteristic strength only. Type B seismic-resistant veneer ties are classified according to stiffness and characteristic strength, which are functions of serviceability, ultimate strength and ductility or toughness. All ties are classified for their corrosion resistance. Provisions are also included for remedial (retrofitted) ties. Test methods are given for determination of :

(a) resistance to water transfer:
(b) characteristic strength and stiffness; and
(c) corrosion resistance.

The types and spacings of ties necessary to meet design requirements are specified in AS 3700, Masonry structures, and NZS 4210, Code of practice for masonry construction materials and workmanship.

AS/NZS 2699.2:2000 - Part 2 Connectors and Accessories

This Standard is the second of the three-part series on masonry wall ties, connectors and accessories, and lintels and shelf angles.

The types and spacings of connectors and accessories necessary to meet design requirements are specified in AS 3700, Masonry structures, NZS 4210, Code of practice for masonry construction: materials and workmanship, and NZS 4230, Code of practice for the design of masonry structures.

The objective of this Standard is to provide manufacturers with specifications for corrosion resistance and tests for structural serviceability of connectors and accessories when built into masonry.

AS/NZS 2699.3: 2000 - Part 3 Lintels and Shelf Angles (durability requirements)

This Standard is the third of the three-part series on masonry wall ties, connectors and accessories, and lintels and shelf angles.

The durability requirements of lintels and shelf angles are specified in AS 3700, Masonry structures and NZS 4210, Code of practice for masonry construction: materials and workmanship, and NZS 4230, Code of practice for the design of masonry

The objective of this Standard is to provide manufacturers of lintels and shelf angles with specifications to achieve these durability requirements and with methods for testing their corrosion resistance.
