The goal of the in-house evaporative emission enclosure (SHED) testing is to develop a concise, accurate, and practical evaporative emission test procedure. One of the critical questions requiring evaluation is whether or not the enclosure method of testing for hot soak emissions presents abnormally high vehicle temperatures. In order to evaluate whether these temperatures do occur in the enclosure, hot soak tests were conducted in the enclosure and in the shop soak area and various temperatures were monitored. The objective of this study was to determine if a maximum enclosure ambient temperature should be specified for the hot soak test and to determine what a reasonable maximum temperature would be with respect to other phases of the test procedure. Also, temperatures near and on the surfaces of the inner and outer walls of the enclosure were measured.
