Manned spacecraft crew module products with materials and components Determination of degassing
Tested under the conditions of drying chamber. 4.3 Sample Analysis 4.3.1 Material screening test samples should be used the following 3 conditions: (a) extrusion of carbon monoxide by the amount of test material, to ~ 'g / g, said; (b) extrusion of organic material to be tested Total (using pentane as an equivalent expression) to express g (c) for more than 10 ~ g / g degassing amount of material being tested, to qualitative and quantitative analysis of each degassing pollutants. 4.3.2 materials or component products of the total test sample should be on all the pollutants generated by the qualitative identification and quantitative analysis. 5 components of the test acceptance limit of 5.1 is not the final authority on the components of the decision. The data up to the security office of the plan for further evaluation. Pollution on the volatile components are produced by the evaluation of toxic effects, depending on the task in a given flight can produce all the items of pollution potential toxicity of the total degassing materials will be components of pollution, however, that acceptance criteria with the following key are linked; (1) the number of objects for each degassing should be lower than the product inside the spacecraft maximum allowable concentration (MAC). (2) degassing the concentration of each corresponding MAC with the ratio should be lower than in a given mission, the weight of such items in the same ratio of the weight of the payload if (1) conditions are not met,[link widoczny dla zalogowanych], then should be seen as out of the items (components) causes. However, this situation may exist, through the high-temperature baking can reduce the degree of pollution produced. This practice should obtain the consent of the relevant program office, and then must re-do the test. If you can not satisfy (2) standards,[link widoczny dla zalogowanych], the test components do not have to stop the data must be evaluated by the program office to determine what kind or level of pollutants in excess of the allowable payload has brought the whole problem. The results of this assessment is to make a decision on next steps. If the above, it is necessary to do so 5.2 Materials 5.2.1 Lian screen material as the first step of the screening test, the method mentioned in this article,[link widoczny dla zalogowanych], you must specify the material to be less than the target level of degassing ; CO 25 ~, g / g total organic matter 100 ~ g / g addition, if the organic matter concentration in any one of prolapse than 10 ~ g / g, should give qualitative analysis identified what kind of material. 5.2.2 General application when the material is added to the component, but too proud of this component has already started the test (due to maintenance or re-processing, etc.) of the cases, the data required in Section 5.1 in connection with the determination of regarded as consistent. If the material meets the standards of Section 5.2.1, it is deemed qualified, acceptable. 6 Quality Assurance. 25 quality assurance requirements in ESAPss-Ol a determined 20. However, the following should also be given special attention. 6.1 in the test report should record the following characteristics. (1) product density representation; solid block with cm, coating class with em, and fiber with linear cm. (2) the quality of substrate or material density, the quality of the material (substrate) ratio to glcm said. (3) After the test time and test temperature atmosphere (normal air enriched hydrogen concentration,[link widoczny dla zalogowanych], etc.). (4) Identification and concentration of pollutants (section 4.3.1, a special note of the material tested is expressed as g / g, g in the other case they are expressed.) (5) was observed during the test event should be recorded. 6.2 Calibration of all test equipment shall be calibrated. 6.3 trace trace should be checked throughout the test until the final test before the whole process. To this end, the task of completing the test the test equipment used, sequence number and staff must be documented. Annex A definition of spacecraft components assembledarticle supplies on behalf of any \Degassing offsassing sample the atmosphere in the specified component by mild thermal radiation changes in the emergence of gas products. Degassing from liquid or gaseous products offgassedproduct materials or components in the release of organic or inorganic gas compounds. The maximum allowable concentration (MAC) maxinumallowedconcentration in the specified test time,[link widoczny dla zalogowanych], the spacecraft atmosphere of volatile degassing the maximum permitted concentration of the product. Manned spacecraft maximum allowable concentration (MAC) value is determined by the planning office. If the MAC value of the program-specific directory, finding out, you can use the MASA specification NHB80601B in Appendix D for a given value. A larvae love / curly. Thirty dollars fling a roMi7 member flight team members have access to the flight path of practice. In this thought, ESA 1992, 26 new tactics
