ethod solves some limitations associated with other closed chamber test methods, such as Test Method E 662 [2-5] (see 5.4.1). The test method retains some limitations related to closed chamber tests, as detailed in 5.5.8.1-5.5.8.5.
Information relating the specific optical density obtained by this test method to the mass lost by the specimen during the test is possible only by using the (optional) load cell, to determine the mass optical density (see Annex A1).
All specimens consume oxygen when
