3. REQUIREMENTS
3.1 Description. The sensitive relay (hereinafter called the relay), Drawing 1521140, is a sensitive, electromagnetic relay with a double-pole double-throw armature. With the coil in its normally deenergized state, the armature closes the circuit(s) through one pair of poles. When the coil is energized and the coil current reaches a predetermined value, the armature moves to close the circuit(s) through the opposite pair of poles, at the same time opening the circuit(s) through the initial pair of poles. When the current in a energized coil is reduced below a predetermined value, the armature will return to the position assumed when the coil is deenergized. The coil is energized from a nominal 10 V dc (or rectified ac) power source.
3.2 Definitions. Definitions applicable to the environmental requirements of this specification are contained in
MIL-T-18404.
3.3 General requirements.
3.3.1 Conflicting requirements. Conflicting requirements arising between this specification or any specifications, publications, or drawings listed herein shall be referred in writing to the acquiring agency or appointed agent for interpretation, clarification, and resolution (or correction).
3.3.2 Data required. No data is required by this specification (other than reports accompanying samples submitted for preproduction and periodic production testing), or by applicable documents referenced in Section 2, unless specified in the contract or order (see 6.2).
3.3.3 Preproduction sample. Unless otherwise specified in the contract or order, preproduction samples of the relays shall be manufactured using the methods and procedures proposed for the production lot. These units shall
be tested as specified in Section 4 herein and are for the purpose of determining, prior to starting production, that the contractor's production methods are capable of producing relays that comply with the technical requirements of the contract (see 4.2.1).
