JAXA imposed odor requirement for non-metallic material used in pressurized cabin of JEM and HTV conventionally and performed odor assesment by testing. Each agency interprets odor requirement variously. As the response to this situation, JAXA reviewed the odor requirement in accordance with following considerations; 1. Odor will be spread in the ISS and weakened. 2. Crew will not smell articles directly in general. 3. Most agencies do not perform odor test to evaluate intencity of odor. 4. Odor requirement is not safety requirement. 5. The merit for schedule and cost by stopping the odor test is very much expected. As a result of the review, JAXA decided not to require Test 6 (Odor Assessment) of NASA-STD-6001 basically. In case of materials which crew would smell directly those odor, such as crew cloth, sleeping bag etc., odor assessment is required for the purpose to keep crew comfort. Odor assessment can be performed by analysis using concentrations of offgassed products taken. JAXA is developing odor sencor (E-Nose). Institute of Aerospace Technorogy (IAT) is now studying about the association of Odor Index which measured by E-Nose and Odor Rating specified in NASA-STD-6001. The status of the study will also be introduced in this presentation.
