Blue M 7780 Ultra-Temp Standard Temperature Convection Oven, 5.8 cu. ft.

RTCA/DO-160 Section 10 analyzes how aircraft responds to water under normal conditions and consists of the following tests: Condensing Water Drip Proof Test (Category Y) Drip Proof Test (Category W) Spray Proof Test (Category R) Continuous Stream Proof Test (Category S) Of the four tests, ATEC rents chambers to complete testing for Category Y. This condensing water test requires the use of two temperature and humidity chambers; chamber 1 set to -10° C and chamber 2 set to 40° with 85% relative humidity. The equipment under test is placed (non-operating) into chamber 1 for three hours, then transferred to chamber 2 and operated for 10 minutes. Upon completion, the equipment is evaluated to determine compliance.     Equipment Categories Category Y Equipment that is installed in locations where it is subjected to condensing water in the course of normal aircraft operations. Category W Equipment that is installed in locations where it is subjected to falling water (generally the result of condensation) in the course of normal aircraft operations. Category R Equipment installed in locations where it may be subjected to a driving rain or where water may be sprayed on it from any angle. Category S Equipment installed in locations where it may be subjected to the forces of a heavy stream of fluid such as would be encountered in aircraft de-icing, washing or cleaning operations.

RTCA/DO-160 Section 5 determines performance characteristics of the equipment during temperature variations between high and low operating temperature extremes. Note: The test is not intended to verify the behavior of the equipment in wet or icing conditions. In conducting this test, the test chamber may incorporate the capability of controlling or altering humidity to the extent that condensation is minimized or does not occur. The rates applicable to the temperature variation procedures defined in Subsection 5.3 are as follows: Category A – For equipment external to the aircraft or internal to the aircraft: 10 degrees Celsius minimum per minute. Category B – For equipment in a non-temperature-controlled or partially temperature controlled internal section of the aircraft: 5 degrees Celsius minimum per minute. Category C – For equipment in a temperature-controlled internal section of the aircraft: 2 degrees Celsius minimum per minute. Category S1 – For equipment external to the aircraft or internal to the aircraft: known rate of change greater than 10 degrees Celsius per minute. The rate of change shall be noted in the Qualification Form. Category S2 – For equipment external to the aircraft or internal to the aircraft: unknown rate of change greater than 10 degrees Celsius per minute.

Significance: This test method is intended for use for evaluating the performance of thermal insulated packaging used for high-value, high-risk materials. This test method may also be used for any product that requires accurate internal package temperature readings while being exposed to a range of external air temperatures. Scope: This test method covers the determination of the thermal insulation quality of a package and the thermal stability of its contents when exposed to variable ambient temperature conditions. It is suitable for testing packages with various internal energy sources with or without product payloads. Download Standard
