17、 AUSTRALIA Australian Standard Aggregates and rock for engineering purposes Part 4: Aggregate for gabion baskets and wire mattresses 1 SCOPE This Standard provides a basis for specifying requirements for aggregates intended for use in gabion baskets and wire mattresses. The requirements relate to qu
18、ality of rock and other properties of coarse aggregate. A coarse aggregate may be produced from rock, gravel, metallurgical slag, recycled material or suitable synthetic materials. 2 APPLICATION This Standard shall be used in conjunction with a works specification for contract purposes. While a numb
19、er of the requirements nominated in this Standard are basic, the specifier shall make a selection from the options available in this Standard, or from alternative test methods and limits (which may be from Australian Standards or other appropriate Standards) for incorporation into a works specificat
20、ion. The basic requirements for all aggregates are given in Clauses 7 to 9. The selection of test procedures and test limits, and the frequency at which individual tests are required, shall be determined by the individual works specification. The works specification should specify all the tests appr
21、opriate to the source rock or the tender samples, or both. The whole range of tests should not be applied to control acceptance of the product during the performance of a contract. For contractual purposes, the works specification is binding. In some cases a contract document uses terms such as mate
22、rial complying with AS 2758.4, without providing a works specification. In such instances, the supplier shall attempt to obtain further details from the purchaser. In the continued absence of a works specification, material will be deemed to comply with this Standard if the supplier operates a quali
23、ty system complying with AS/NZS ISO 9002 and can provide test data from a laboratory accredited to SAA HB18.25 showing that material to be supplied fulfils the requirements of Clauses 7 to 9 of this Standard 3 REFERENCED DOCUMENTS AS 1141Methods for sampling and testing aggregates 1141.3.1 Method 3.
