1.1  Scope
This Standard specifies requirements for wall ties for use in tying together — (a) the leaves of cavity masonry walls; (b) masonry veneer walls and loadbearing frames; and (c) masonry veneer walls against a strong backing wall. This Standard applies to wall ties used in masonry described in AS 3700, AS 4773.1, and AS 4773.2, including those used in thin-jointed masonry [for example, autoclaved aerated concrete (AAC) blockwork]. NOTE 1  Type B wall ties are not used in this Standard. For Type B wall ties, refer to AS/NZS 2699.1:2000, which provides definitions, embedment, movement and tolerance requirements, marking, and methods of testing. NOTE 2  AS 2699.2 specifies the durability performance and test procedures for structural performance of connectors and accessories used in masonry construction. NOTE 3  AS 2699.3 specifies the requirements for durability of lintels and shelf angles. NOTE 4  This Standard gives categories of wall ties, and classifies wall ties by mean strength and durability. NOTE 5  The durability classifications employed in this Standard are compatible with the environments specified in ISO 9223, AS 4312—2008, AS 3700, AS 4773.1 and AS 4773.2. NOTE 6  Design and installation of wall ties are specified in AS 3700 and AS 4773.1 (design) and AS 4773.2 (construction).
1.3  Terms and definitions
For the purpose of this Standard, the definitions below apply. 1.3.1 batch clearly identifiable collection of units, manufactured consecutively or continuously under the same conditions, using material or compound to the same specification 1.3.2 cavity tie wall tie designed to connect two leaves of masonry that are separated by a clear cavity of any width 1.3.3 corrosivity category C standardized rating of corrosivity of atmosphere in relation to the one-year corrosion effect on steel and zinc Note 1 to entry: The classifications C1 to C5 and CX are individually defined by reference to corrosivity of the atmosphere according to ISO 9223 and AS 4312—2008. Note 2 to entry: A method for estimating corrosivity category is given in Appendix D. 1.3.4 design life period for which the wall tie is expected to fulfil its intended function Note 1 to entry: See Clauses 1.3.27, 1.3.28 and 1.3.29. 1.3.5 distributor any business entity that provides a point/source of supply of a wall tie to the market 1.3.6 durability class R identifies the level of corrosion protection provided to a tie to meet the performance condition for the design life of a structure Note 1 to entry: The classifications R1 to R5 are individually defined by reference to exposure conditions given in AS 3700, AS4773.1 and AS 4773.2. 1.3.7 duty classification classification that identifies the mean strength rating for wall ties Note 1 to entry: The identification of mean strength rating for wall ties is given in Clause face loads loads applied normal to the face of the wall, which impose compressive or tensile forces on the ties 1.3.9 factory production control FPC comprises operational techniques and all measures necessary to regulate and maintain the conformity of the product to the requirements of a Standard 1.3.10 galvanized coating protective zinc coating alloyed to the steel substrate and applied by hot-dip immersion in molten zinc of at least 98 % purity 1.3.11 lot group of wall ties of a single type with specific characteristics and dimensions, presented for sampling at the same time 1.3.12 manufacturer business entity providing the total, substantive or final production/assembly process of the wall tie 1.3.13 manufacturing lot manufacturing batch quantity of wall ties of a single type with specific characteristics and dimensions, processed through the same or similar steps at the same time or over a continuous time period from a process with FPC 1.3.14 manufacturing lot number unique alphanumeric code assigned by the wall tie manufacturer to a manufacturing lot enabling its traceability throughout the entire production operation, including incoming materials control and all processes defined in the FPC 1.3.15 masonry couplet two stack-bonded masonry units joined by a bed of mortar or adhesive, as appropriate 1.3.16 mean strength of a tie (F t ) mean strength of a tie appropriate to its duty rating Note 1 to entry: The mean strength of a tie is calculated in accordance with Appendix F for Type A ties and is consistent with the requirements of AS 3700
