ABSTRACT
Where possible the conditions at testing should be the same as those in the conditioning chamber, but where this is not possible, tests should be carried out immediately after the specimens have been removed from the conditioning chamber.
For many investigations it will be sufficient simply to record the grade of each specimen according to established vtsual or mechanical stress grading rules. However, when ultimate strength is to be determined, the value of the test results will be enhanced if the magnitude of the growth characteristics and defects present in the test specimen, or the magnitude of an indicating parameter for machine stress grading, are recorded.
