This Technical Report provides guidelines for setting gauging (or test) limits in support of accept/reject decisions in workpiece inspections, instrument verifications, and general conformance tests where uncertain numerical test results are compared with specified requirements. In accepting or rejecting workpieces or instruments based on the results of inspection measurements, the presence of unavoidable measurement uncertainty introduces the risk of making erroneous decisions. By implementing a decision rule that defines a range of acceptable measurement results, one can balance the risks of rejecting conforming workpieces or instruments and accepting nonconforming ones.

1.1 This test method determines the apparent coefficient of linear thermal expansion of solid materials using thermomechanical analysis techniques. Related information can be found in Refs. (1-12)178;.1.2 This test method is applicable to solid materials that exhibit sufficient rigidity over the test temperature range such that the sensing probe does not produce indentation of the specimen.1.3 The recommended lower limit of coefficient of linear thermal expansion measured with this test method is 5 m/(mC). The test method may be used at lower (or negative) expansion levels with decreased accuracy and precision (see Section 11).1.4 This test method is applicable to the temperature range from 120 to 900 C. The temperature range may be extended depending upon the instrumentation and calibration materials used.1.5 Computer or electronic based instruments, techniques, or data treatment equivalent to this test method may also be used. Note 18212;Users of this test method are expressly advised that all such instruments or techniques may not be equivalent. It is the responsibility of the user to determine the necessary equivalency prior to use. 1.6 SI values are the standard.1.7 This test method is related to ISO 11359-2 but is significantly different in technical detail.1.8 This standard does not purport to address all of the safety problems, 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.

It has been shown that bending stresses that inadvertently occur due to misalignment between the applied force and the specimen axes during the application of tensile and compressive forces can affect the test results. In recognition of this effect, some test methods include a statement limiting the misalignment that is permitted. The purpose of this practice is to provide a reference for test methods and practices that require the application of tensile or compressive forces under conditions where alignment is important. The objective is to implement the use of common terminology and methods for verification of alignment of test machines, associated fixtures and test specimens. Unless otherwise specified, axiality requirements and verifications should be optional when testing is performed for acceptance of materials for minimum strength and ductility requirements. This is because any effects especially from excessive bending, would be expected to reduce strength and ductility properties and give conservative results. There may be no benefit from improved axiality when testing high ductility materials to determine conformance with minimum properties. Whether or not to improve axiality should be a matter of negotiation between the material producer and the user.1.1 Included in this practice are methods covering the determination of the amount of bending that occurs during the application of tensile and compressive forces to notched and unnotched test specimens in the elastic range and to plastic strains less than 0.002. These methods are particularly applicable to the force application rates normally used for tension testing, creep testing, and uniaxial fatigue testing.

This Technical Report gives the detailed evaluation of uncertainty for volume measurements according to the Guide to the expression of uncertainty in measurements (GUM). ISO 8655-7 covers non-gravimetric methods of volume measurement. ISO 8655-7:—, Annex A, presents the details of a method that employs removable cells (vials) in a UV/VIS photometer. ISO 8655-7:—, Annex B, presents the details of a method that employs a flow cell fixed in place in a UV/VIS photometer. This Technical Report covers the uncertainty of measurement of both methods.
