6、th ISO7137:1995 Aircraft Environmental conditions and test procedures for airborne equipment, published by the International Organization for Standardization (ISO). This British Standard supersedes BS3G229:1993, which is withdrawn. The Technical Committee has reviewed the provisions of EUROCAE/ED-14
7、C, RCTA/DO-160C and ISO2671 to which normative reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A related British Standard to ISO2671 is BS3G100-2.3.14:1973. NOTEThe latest edition of an Aerospace series standard is indicated by a pre

12、nternational Standard lists the different environmental conditions and test procedures for airborne equipment and is primarily intended for civil and/or transport aircraft applications. This International Standard is an endorsement ofsections of publications EUROCAE/ED-14C andRTCA/DO-160C 1) , which
13、 supplement several ISO International Standards. 2 Requirements Environmental conditions and test procedures applicable to airborne equipment are laid downinEUROCAE/ED-14C and RTCA/DO-160C, 1989-12-12 editions, amended in accordance with revision No.2 (1992-06-19), which are adopted as de facto ISO
14、International Standards. All environmental conditions and test procedures laid down in EUROCAE/ED-14C and RTCA/DO-160C are not necessarily applicable to all airborne equipment. The selection of the appropriate environmental conditions and test procedures is the responsibility of the writer (author)
15、of the performance standards for the specific airborne equipment. 3 Test procedures The test procedures given inTable 1 are issued or endorsed by ISO. 4 Reference to ISO test procedures When referring to environmental conditions and test procedures dealt with in this International Standard, referenc
16、e shall be made to the number of this International Standard and to the reference number of the test procedure as given inTable 1. Use the example given below as a model. EXAMPLE Reference to the test procedure for fluids susceptibility in accordance with section11 of EUROCAE/ED-14C and RTCA/DO-160C
