As 1163 - Hollow Sections for Structural Steel

AS 1163—1991Australian Standard® Structural steel hollow sections This Australian Standard was prepared by Committee BD/23, Structural Steel. It was approved on behalf of the Council of Standards Australia on 30 August 1991 and published on 15 November 1991. The following interests are represented on Committee BD/23: Australian Chamber of Manufacturers Australian Institute of Steel Construction AUSTROADS Bureau of Steel Manufacturers of Australia Confederation of Australian Industry Institute of Steel Service Centres of Australia Master Builders Construction and Housing Association Australia Metal Trades Industry Association of Australia Railways of Australia Committee Steel Reinforcement Institute of Australia University of Queensland University of Sydney Review of Australian Standards. To keep abreast of progress in industry, Australian Standards are subject to periodic review and are kept up to date by the issue of amendments or new edit ions as necessary. It is important therefore that Standards users ensure that they are in possession of the latest edit ion, and any amendments thereto. Full detail s of all Australi an Standards and related publications will be found in the Standards Australi a Catalogue of Publications; this informati on is supplemented each month by the magazine ‘The Australi an Standard’, which subscribing members receive, and which gives details of new publi cati ons, new edit ions and amendments, and of withdrawn Standards. Suggesti ons for improvements to Australian Standards, addressed to the head off ice of Standards Australi a, are welcomed. Noti fi cati on of any inaccuracy or ambiguity found in an Australian Standard should be made without delay in order that the matter may be investigated and appropriate action taken.

B5 OTHER MEANS OF ASSESSMENT If the above methods are considered inappropriate.2 and B5. determination of compliance with the requirements of this Standard may be assessed on the basis of the results of testing coupled with the manufacturer’s guarantee of product conformance. it requires the manufacturer to maintain an effective quality plan to control production to ensure conformance with the relevant Standard. (d) Other such means proposed by the manufacturer or supplier and acceptable to the customer. (c) Assurance using the acceptability of the supplier’s quality system. The StandardsMark serves to indicate that the products consistently conform to the requirements of the Standard. impact test and cold flattening test Test samples should be taken as follows: (a) One sample for a batch not exceeding 50 tonnes. In order for statistical sampling to be meaningful to the customer. COPYRIGHT . The StandardsMark can only be used by manufacturers approved and licensed by Standards Australia and only when accompanied by the number of the applicable Standard.3. The quality assurance requirements need to be agreed between the customer and supplier and should include a quality or inspection and test plan to ensure product conformity. B2 STATISTICAL SAMPLING Statistical sampling is a procedure that enables decisions to be made about the quality of batches of items after inspecting or testing only a portion of those items.11 AS 1163—1991 APPENDIX B MEANS FOR DEMONSTRATING COMPLIANCE WITH THIS STANDARD (Informative) B1 SCOPE This Appendix sets out the following different methods by which compliance with this Standard can be demonstrated by the manufacturer or supplier: (a) Assessment by means of statistical sampling. as well as full type testing from independently sampled production and subsequent verification of conformance. (b) The use of Standards Australia’s StandardsMark scheme. Guidance in determining the appropriate quality management system is given in AS 3900 and AS 3904. Sampling and the establishment of a sampling plan should be carried out in accordance with AS 1199.1 Sampling of tensile test. consideration may be given to the results of testing in accordance with Paragraphs B5. B5. the responsibility remains with the manufacturer or supplier to deliver products that conform with the full requirements of the Standard. guidance to which is given in AS 1399. a suitable sampling plan is defined. (b) For each different situation. the manufacturer or supplier needs to demonstrate how the above conditions have been satisfied. This procedure will only be valid if the sampling plan has been determined on a statistical basis and the following requirements are met: (a) The sample is drawn randomly from a population of product of known history that enables verification that the product was made from known materials at essentially the same time by essentially the same processes and under essentially the same system of control. B3 PRODUCT CERTIFICATION — STANDARDSMARK The general purpose of StandardsMark certification is to provide independent assurance of the claim by the manufacturer that products comply with the stated Australian or International Standard.1. It is a certification scheme that meets the criteria of an ISO Type 5 scheme as specified by ISO Guide 44 in that. such demonstration may provide the necessary confidence that the specified requirements will be met. B5. (b) One additional sample from the balance of the batch. To assess compliance with this specification. A sampling plan for one manufacturer of given capability and product throughput may not be relevant to another manufacturer producing the same items.

If one of these additional samples fails to comply.3 as appropriate. (d) Reprocess (e. If the test pieces from both additional samples comply with Clause 16.1.

(b) Take two further test samples at random from the remainder of the test batch. heat-treat) the units which failed and perform another complete set of tests in accordance with Paragraph B5. (c) Take test samples from each rolled unit of steel and individually test in accordance with this Standard.2 Compliance Each batch complies with this Standard if all of the samples tested give results which are within the specified limits. (d) Reprocess (e. B5.3 as appropriate. If the test piece from the additional sample complies with Clauses 16.

(b) The wall thickness is greater than the section being assessed. This limit is recognized in AS 1210. grain size and steel cleanliness. 10 × 10. that section is considered to comply with the requirements of grade L0 if other hollow sections are available and meet the following criteria: (a) The steel used is of the same nominal chemistry.0. D3 BACKGROUND This Standard recognizes the following principles: (a) The preferred lower size limit for CVN impact tests is 10 × 2. The level of cold strain is proportional to the thickness to perimeter ratio. e. (b) Susceptibility to brittle fracture is directly proportional to the wall thickness of the section being considered. e. (c) The thickness to perimeter ratio is equal to or greater than the section being assessed. It is generally recognized that brittle fractures do not occur in material less than 3. carbon content and carbon equivalent. 10 × 7. manufactured by the same steelmaking and strip processing procedures. D2 METHOD Where it is impracticable to obtain a standard subsize specimen. 10 × 5. (ii) Steel microstructure. 10 × 2.g. i. (c) The manufacturing factors that affect CVN impact values are as follows: (i) Steel chemistry.5 mm substandard specimens.0 mm thick.5 mm from a hollow section.e.
