3 Minimum performance standard — general
       (1)The equipment must meet the requirements mentioned in:
(a) section 2 of RTCA/DO-181; or
(b) ED-73.
       (2)The equipment must have a design assurance level commensurate with its failure condition classification as "major".
Note   The concept of failure condition classification is described in the appropriate certification specification guidance material. For example, EASA AMC 25.1309.

4 Minimum performance standard — environmental test
       The equipment must be tested in accordance with the test conditions mentioned in RTCA/DO-160D or ED-14.

5 Minimum performance standard — fire protection
       The material used in the equipment, other than small parts (such as knobs, fasteners, seals, grommets and small electrical parts) that would not contribute significantly to the propagation of a fire, must be self-extinguishing in the event of fire.

6 Minimum performance standard — marking
       (1)The equipment must be permanently and legibly marked with the following:
(a) either:
           (i) the class of the equipment in accordance with RTCA/DO‑181 or ED‑73; or
           (ii) if the equipment meets more than 1 class — the class with the more stringent requirements;
(b) if the equipment is of a level within the meaning of ED‑73 — either:
           (i) the level of the equipment in accordance with ED‑73; or
           (ii) if the equipment meets more than 1 level — the level with the more stringent requirements;
(c) the environmental categories over which the equipment has been designed to operate mentioned in Appendix A of RTCA/DO-160F;
(d) if an environmental test procedure is not applicable and the test is not conducted — an "X" in the space in which the category would otherwise be marked.
       (2)Subject to subclause (3), each component of the equipment, including the antenna and receiver-transmitter, must be permanently and legibly marked with:
(a) the name of the manufacturer; and
(b) "ATSO-1C112"; and
(c) the environmental categories over which it is designed to operate.
       (3) Subclause (2) does not apply to a component, other than the antenna and receiver-transmitter, to the extent the shape, size or nature of the
