1.1 This practice covers the information that must be provided on certificates of analysis of reference materials designated to support ASTM methods. It provides end users of these materials with a defined set of data that is required to be on a certificate of analysis and provides information to...

1.1 This guide covers practices and image quality measuring systems for the detection, display, and recording of CR data files. These data files, used in materials examination, are generated by penetrating radiation passing through the subject material and producing an image via a storage phospho...

1.1 This guide covers techniques that can be used to calibrate a ground-water flow model. The calibration of a model is the process of matching historical data, and is usually a prerequisite for making predictions with the model.

1.2 Calibration is one of the stages of applying a ground-wat...

1.1 This test method covers calibration or verification of calibration or both, of surface-stress measuring devices used to measure stress in annealed and heat-strengthened or tempered glass, using polariscopic or refractometry based principles.

1.2 This test method is nondestructive. </...

1.1 Polarimeters of polariscopes used for measuring stress in glass are described in Test Methods F218, C148, and C978. These instruments include a light source and several optical elements (polarizers, optical retarders, filters, and so forth) that require occasional cleaning, realigning, and ca...
