SCOPE This standard applies to ar
20、mature-type, circuit-board-mounted relays permitting board center spacings of less than 1 inch. These relays generally are classed in the load range of O to. 2 amperes. This document is intended to help define standard packages, footprints and test conditions so as to promote interchangeability. Rel
21、ays conforming to this standard are suitable for use in electrical and electronic equipment where application is within the stated limits of operation. Relays conforming to this standard may be tested as defined in applicable sections of EIA-407A, EIA/NARM Standard Testing Procedures for Relays for
22、Electrical and Electronic Equipment. This standard does not apply to either mercury-wetted or dry-reed relays. 2.

24、3.1 General 3.1.1 The methods nd measuring techniques described herein are generally accepted procedures. Equivalent methods may be used if agreed upon by the manufacturer and user. 3.1.2 The applicability of the tests and methods cited herein depends upon the type of relay and its intended function
25、. Requirements, applicable test procedures, and performance criteria, therefore, should be specified in the individual relay specifications. The specifications shall also indicate whether data are to be recorded on a variables or attribute basis and shall list disposition instructions for the test d
26、ata. 3.1.3 The values specified in this publication are those used and accepted in the industry. 3.2 Standard Reference Conditions The reference conditions for characteristics that are affected by atmospheric conditions shall be: (1) Temperature (2) Relative humidity 20-50 percent (3) Barometric pre

28、s and Instruments Inaccuracies in measurements shall not be considered as effectively increasing the specified tolerances. Proper and efficient use of instruments of sufficient accuracy and suitable quality is essential. Instruments shall be calibrated and calibration records made available if requi
29、red. For pointer type instruments the required reading should reach at least 60 percent of the deflection range of the instrument to assure adequate reading resolution. 3.4 Performance of Tests Suitable visual or automatic means for monitoring all tests shall be provided to assure that tests are con

Ampere Turns (AT): The product of the number of turns of wire in an electromagnetic coil winding and the current in amperes passing through the winding. Armature: The moving magnetic member or members of an
32、 electromagnetic relay structure. Back Contact: Normally closed contact in a Form C switch (transfer switch). See Contact, Break-Before-Make. Bias, Electrical: An electrically produced force tending to move the armature towards a given position. Bias, Magnetic: A steady magnetic field (permanent mag

Bobbin: Coil form or spool on which a coil is wound. Bounce, Contact: Internally caused intermittent and undesired o
34、pening of closed contacts, or closing of open contacts of a relay caused by: (1) impingement of mating contacts, or . (2) impact of the armature against the coil core on pickup or against the backstop on dropout, or (3) momentary hesitation, or reversal, of armature motion during pickup or dropout.

36、t faces to cause an electrical path between them, or (3) a form of contact erosion occurring on the break of a low-voltage, low-inductance circuit, at the instant of separation, that results in melting and resolidifying of contact metal in the form of a metallic protrusion or bridge . Chatter, Conta

A change in contact resistance without a physical separation of the contact surfaces is referred to as dynamic resistance and appears on the screen of an oscilloscope ha

Coil: An assembly consisting of one or more windings on a common bobbin. Coil Power Dissipation: The electrical power (watts) dissipated by the energized winding or wind
39、ings of a coil. Contacts: The current-carrying parts of a switch that engage or disengage to open or close electrical circuits. Contact, Break-Before-Make: A contact combination in which one contact opens its connection to another contact and then closes its connection to a third contact. Also, a co
40、ntact combination in which the opening contact opens before the closing contact closes. Form C contact; single pole, double throw (SPDT).
