ABSTRACT

These recommendations apply to bars before use as ordinary reinforcement in concrete work. They are characterised principally by their tensile strength and/or their yield stress, by their sectional area and in particular by the profile shape and dimension, These characteristics are given in the catalogues or by the supplier,

These recommendations only apply to tests on the finished products and not on the steels from which these products are made (1),

2.1 The test consists in submitting a length of bar to a load and minimum load. tensile pulsation between two loads described as maximum

2.2 The object of such a fatigue test may be:

a) The investigation of a fatigue property for an unknown product (for example, for certification tests);

b) Quality control of the fatigue property previously determined for the same product (for example, for acceptance tests or quality control).
