1. Scope

1.1 This test method, known as the high-temperature hot box method (calibrated or guarded), covers the measurement of thermal conductance, thermal transference, and thermal transmittance of insulation panels from a heated surface temperature of approximately 40°C (104°F) to the maximum insulation design temperature, not to exceed 540°C (1000°F). In distinction to Test Method C 177, which is primarily applicable to homogeneous samples, and Test Method C 236, which is primarily applicable to measurements on panels representative of such constructions as walls, roofs, and floors of buildings, the high-temperature hot box method is designed for measurements on nonhomogeneous panels representative of such constructions as metal reflective insulation panels for nuclear power plants and prefabricated insulation panels for fossil power plants.

1.2 In a test method as complicated as the hot box method, it is not practical or desirable to establish the construction in such detail that the method could be used by a person not technically trained. However, the general principles outlined in this test method must be followed. It shall be understood, therefore, that those applying the test method shall be trained in the methods of temperature measurement, shall possess a knowledge of the theory of heat flow, and shall understand the general requirements of testing practice. In standardizing this test method, it is recognized that it would be unwise to restrict, unnecessarily, the initiative of research workers who may wish to develop and improve the test method. Accordingly, in the description of the apparatus given in Section 6, the essential principles and the general arrangement of the apparatus are first given; any test following this method must satisfy these general requirements, The details of the apparatus and the suggested test procedure that follow are given, not as mandatory requirements, but simply as examples of methods and precautions that have been found useful in the past to satisfy the general principles. It is realized that the variation of types of structures to be tested may be so great, and the demands of the conditions so different, that it would be a mistake to restrict the test method unnecessarily and to confirm all measurements to a single experimental arrangement.

1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safely problems 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.
