B557 − 15 8.3 In the case of separately cast test specimens, flaws other than gas porosity, such as cracks or inclusions, are not the cause of rejection of the castings based upon tensile properties, and so the presence of such flaws in the fracture is justification for replacement testing. Retests 9.1 If one or more test specimens fail to conform to the requirements of the product specification, the lot represented by the specimen or specimens shall be subject to rejection except as provided as follows. 9.2 If a material lot is subject to rejection, retests of that lot will be permitted by: 9.2.1 Testing, for each specimen that failed, at least two additional specimens from an area in the original sample adjacent to the area represented by the failure or failures, or 9.2.2 Testing an additional specimen from the specified location in each of at least two other samples for each sample that failed from the same lot. 9.2.3 In the case of separately cast test specimens, testing two additional cast specimens from the same lot for each specimen that failed. 9.3 If any retest fails, the lot shall be subject to rejection, except that the lot may be resubmitted for testing provided the producer has reworked the lot, as necessary, to correct the deficiencies or has removed the nonconforming material.
This information may be useful in comparisons of materials, alloy development, quality astm b557, and design under certain circumstances. Although various types of grips can astm b557 used astm b557 gripping the samples, the recommended grips are wedge grips with serrated inserts. Unless otherwise specified, any convenient speed of testing may be used up to one half astm b557 specified yield strength, or up to one quarter the specified tensile strength, whichever is smaller. The speed may be increased after astm b557 removal of extensometer, but it should not exceed 0. This method determines the strength and ductility of materials under uniaxial tensile stresses.

The direction of the specimens shall be in the longitudinal grain direction, unless specimens in other directions are required. For aluminum die forgings, the longitudinal grain direction is defined as orientations parallel, within 615°, to the predominate grain flow. The long transverse grain direction is defined as perpendicular, Copyright by ASTM Int'l (all rights reserved); Thu Aug 17 06:01:40 EDT 2017 7 Downloaded/printed by Orta Dogu Teknik Universitesi (Orta Dogu Teknik Universitesi) pursuant to License Agreement.
Scope* 1.1 These test methods cover the tension testing of wrought and cast aluminum- and magnesium-alloy products, with the exception of aluminum foil,2 and are derived from Test Methods E8, which cover the tension testing of all metallic materials. 1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. NOTE 1—Foil is sheet metal less than 0.0079 in. There is an overlap in the thickness range 0.006 to 0.0079 in.
