24、2:2014 (E) 4 1 Scope Several classes of materials depend on a chemical reaction for their application and their final properties are sensitive to the exact composition of the reactants. The final properties vary with the reactants age and storage condition. This Standard defines the requirements for
25、 the identification, handling, storage and control of limited shelf-life materials employed in the fabrication of spacecraft and associated equipment. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00. DIN EN 16602-70-22:

Materials and parts with hazardous characteristics shall be identified a
32、nd manage in conformance with the “Safety programme plan” specified in ECSS-Q-ST-40. b. Procedures to control hazards, health and safety to personnel, equipment or materials shall be defined and implemented. 4.1.2 Material control 4.1.2.1 Procurement document a. For procurement specifications and pu
33、rchase orders, the date of manufacture, storage conditions and shelf-life of the products shall be declared. 4.1.2.2 Identification a. Materials shall be labelled with the shelf-life and the date of the beginning of life or the date of manufacture (see clause 4.1.3). NOTE In some critical applicatio
34、ns, the project can reduce the shelf-life as originally stated by the manufacturer or supplier in order to meet particularly stringent product assurance requirements. b. For quantities which are split from a batch, it shall be ensured that materials are fully traceable to it and bear the same date a
35、nd life indications. 4.1.2.3 Storage a. Materials shall be stored in a nominally clean area at (22 3) C with a relative humidity of (55 10) % unless specified otherwise by the manufacturer or supplier. DIN EN 16602-70-22:2015-06 EN 16602-70-22:2014 (E) 8 NOTE A wide range of pre-impregnated composit
36、es, adhesives and related materials which are used in the fabrication of spacecraft structures at lower temperatures to preserve their shelf-lives. Refer to clause 4.1.3. b. Storage areas shall be organized and controlled in such a way that limited shelf-life items are identified. NOTE The reason is
37、 to avoid the possibility of over-aged material being used. 4.1.2.4 Handling a. Materials shall be handled with clean lint-free or nylon gloves unless their use is precluded for reasons of safety. NOTE For example, when handling corrosive, toxic and oxidizing substances. 4.1.3 Assessment of shelf-li
38、fe a. If the shelf-life cannot be obtained, the following steps shall be performed: 1. Certify the material at incoming inspection. NOTE Perform tests relevant to the application of the material to ensure that the properties are within those values either specified within the procurement specificati
39、on or in the manufacturers data sheet (where no procurement specification exists). 2. Where satisfactory results are obtained, state that the material has spent half its shelf-life at the time of delivery. 3. If the results are not satisfactory, reject the material. 4. Put the date of manufacture an
40、d shelf-life on the label attached to limited shelf-life material in conformance with clause 4.1.2.2. b. The quantity in each container shall be compatible with the planned short term usage. NOTE The reason is that the number of container openings is kept to the minimum possible. c. Materials shall
41、be decanted from larger into smaller containers if there is large air space above the material. d. For materials which are stored at temperature below zero, a system shall be defined and implemented to record the time exposed to room temperature and the consequent reduction in shelf-life when return
42、ed to low temperature storage. NOTE For materials normally stored at low temperature (below zero), exposure to room temperature can dramatically reduce the shelf-life. e. It shall be ensured that all materials stored at temperatures below room temperature are allowed to attain room temperature prior
43、 to use. DIN EN 16602-70-22:2015-06 EN 16602-70-22:2014 (E) 9 4.1.4 Extension of shelf-life (re-certification) a. To extend the shelf-life of a material that has exceeded its shelf-life, the following activities shall be performed: 1. Re-certify the material for the first time by using the relevant
44、tests in conformance with clause 4.1.6; 2. If the first re-certification is successful, extend the shelf-life equal to half the initial shelf-life; 3. Re-certify the material for the second time on a case-by-case basis depending on product, application, storage and user experience; 4. If the second
45、re-certification is successful, extend the shelf-life to half of the first extension. b. If a fully traceable, non-over-aged batch is suspect, for any reason, the user shall submit it for re-certification. c. Batches awaiting results of a re-certification process separately and shall be labelled as
46、“suspended”. 4.1.5 Disposal of materials a. In case further re-certification is not permitted or traceability has been lost for a batch, or part of a batch, the user shall dispose the material in conformance with the product assurance rules applicable to the project. 4.1.6 Acceptance criteria, re-ce
47、rtification testing a. Re-certification of material shelf-life shall be achieved by retesting the material to verify that its properties are still within their specified limits. b. Retesting shall include those properties specified in the procurement specification or performed during incoming inspec
48、tion. NOTE The choice of properties to be measured is based on a combination of the final application of the material and its processing. c. The choice of properties to be measured and test methods to be used shall be subject to the approval of product assurance. NOTE For examples of properties to b
49、e measured see Annex B. 4.2 Quality assurance 4.2.1 Data a. Quality records shall be retained for ten years or in conformance with project business agreement requirements. NOTE E.g. logbooks. b. The quality records shall be in conformance with Annex A. DIN EN 16602-70-22:2015-06 EN 16602-70-22:2014 (E) 10 4.2.2 Calibration a. Any measuring equipment shall be calibrated to traceable reference standards. b. Any suspected or actual equipment failure shall be recorded as a project nonconformance report according to th
