A CODE OF PRACTICE FOR CONSTANT‐AMPLITUDE LOW CYCLE FATIGUE TESTING AT ELEVATED TEMPERATURES

Abstract

Abstract— This paper comprises the text of a code of testing practice prepared under the auspices of a British High Temperature Mechanical Testing Committee. The code makes recommendations concerning equipment, test specimens and procedures; it includes several explanatory and cautionary notes and references to related standards and publications. It was considered that the American National Standard ASTM E606–80 [1] contained much of the required material and in order to avoid unnecessary divergence of practice the recommendations therein have been used as far as possible but with specific modifications and additions to account for current UK needs and practice. It is anticipated that this document may form the basis of a future BSI publication and consequently, the general format is similar to that recommended by BSI in BS O 1981 [2]. Currently a programme of intercomparative Low Cycle Fatigue testing is being carried out under the auspices of and with support from the Community Bureau of Reference (BCR) of the Commission of European Communities. This programme will shortly be widened to include non‐European countries as part of a broader initiative in the field of Materials and Standards (VAMAS). In consequence it is intended to consider and, if necessary, revise the Code of Practice in the light of results from this programme and of other on‐going work in the field.
