1.1 Purpose
Use high temperature tests to obtain data to help evaluate effects of high temperature conditions on materiel safety, integrity, and performance.
1.2 Application
Use this method to evaluate materiel likely to be deployed in areas where temperatures (ambient or induced) are higher than standard ambient.
1.3 Limitations
Limit use of this Method to evaluating the effects of relatively short-term (months, as opposed to years), even, distributions of heat throughout the test item. This Method is not generally practical for:
- a. Evaluating time-dependent performance degradation (aging) effects that occur during continuous long-term exposure to high temperatures (under storage or operational modes) where synergetic effects may be involved. For such high temperature aging effects, test in the natural environment.
- b. Evaluating materiel in a high temperature environment where solar radiation produces significant thermal gradients in the materiel. For simulating direct solar impingement, use Method 505.7, Procedure I.
- c. Evaluating actinic (photochemical) effects (use Method 505.7, Procedure II).
- d. Evaluating the effects of aerodynamic heating without considerable tailoring.
