3、ications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular
4、need. Existence of such Standards and Publications shall not in any respect preclude any member or nonmember of EIA/TIA from manufacturing or selling products not conforming to such Standards and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by
5、 those other than EIA/TIA members, whether the standard is to be used either domestically or internationally. Recommended Standards and Publications are adopted by EIA/TIA without regard to whether their adoption may involve patents on articles, materials, or processes. By such action, EIA/TIA does
6、not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Recommended Standard or Publication. This EIA/TIA Standard is considered to.have International Standardization implication, but the International Electrotechnical Commission activity has
7、not progressed to the point where a valid comparison between the EIA/TIA Standard and the IEC document can be made. This Standard does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Standard t
8、o establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use.

9、 then dry the specimens completely by exposing them to room ambient conditions for 20 to 24 hours, or by drying them in a circulating air oven at 48.9 & 2.8 OC for 2 to 3 hours. 5.6 Final Inspection. After drying, repeat the visual and physical examination of each specimen (as performed in 5.1) in a
10、ccordance with FOTP-13, checking especially for (a) deterioration of moisture seals, (b) evidence of foreign deposits on connector interfaces. Record observations.

Perform calculations as specified by any required optical test (FOTP-20, FOTP-34, FOTP-107, etc.). 6.2 Precision. The altitude-immersion test method
12、has been in use for many years, but no statement for precision has been made and no activity is planned to develop such a statement. Precision of optical measurements is as given by the specified measurement FOTP. 6.3 Bias. A statement of bias is not possible due to a lack of a standard reference ma

Include fixture, if applicable. 7.1.4 Values and observations: 7.1.4.1 Chamber pressure, temperature, and duration
14、 of each cycle, 7.1.4.2 Optical test data, before and after altitude immersion. 7.1.4.3 Results of visual examination. 7.2 United States military applications require that the following information also be reported for each test. For other (non-military) applications, this information need not be re
15、ported but shall be available for review upon request. 7.2.1 Test equipment used and date of latest calibration. P 7.2.2. Test personnel.
