11、CEDURE No. 100A MARKING PERMANENCE TEST PROCEDURE FOR ELECTRICAL CONNECTORS AND SOCKETS (From EIA Standards Proposal No. 5226.10, formulated under the cognizance EIA CE-2.0 Committee on National Connector Standards, and previously published in EIA-364-100.) 1 Introduction 1.1 Scope This standard est

12、ablishes a method of determining the marking permanence of electrical connectors and sockets. 1.2 Object The object of this test procedure is to determine the ability of a connector or socket to withstand solvents that may be used to clean components as well as to determine marking and color code in

13、tegrity. Table 1 - Solvent classes and description Classes Description 1 Alcohol and mineral spirits; see 2.2.1 2 Terpene defluxer; see 2.2.2 3 Water, propylene glycol monoethanolamine, and monoethanolamine; see 2.2.3 1.3 Safety The solvents listed in 2.2 exhibit some potential for health and safety

14、 hazards, and the following safety precautions shall be observed. 1.3.1 Avoid contact with eyes. Chemical goggles shall be worn while performing test. 1.3.2 Avoid prolonged contact with skin. 1.3.3 Perform all work in a laboratory fume hood, or provide adequate ventilation. EIA-364-100A Page 2 1.3.4

15、 It is recommended that the solutions be heated in an explosion-proof laboratory hood. Do not use open flame. Hot plate may also be used. NOTE Refer to the manufacturers material safety data sheets for emergency first aid procedures. 2 Test resources 2.1 Equipment 2.1.1 Basket: Stainless steel mesh

16、basket of sufficient size. 2.1.2 Brush: Toothbrush made of materials that are nonreactive with the solvent being used. Brush shall have three long rows of hard bristles, whose free ends shall be substantially in the same horizontal plane. The brush shall be discarded at the completion of the test. 2

17、.1.3 Vessel: Heat-resistant beaker or vapor degreaser made of nonreactive material and of sufficient size to hold the basket. 2.1.4 Laboratory fume hood. 2.1.5 Explosion-proof heat chamber, or hot plate. 2.2 Material All organic solvents shall be American Chemical Society technical grade or better.

18、2.2.1 Class 1 solvent A mixture consisting of the following: 2.2.1.1 One part by volume isopropyl alcohol. 2.2.1.2 Three parts by volume mineral spirits, or three parts by volume of a mixture of 80% by volume of kerosene and 20% by volume ethylbenzene. 2.2.2 Class 2 solvent A terpene defluxer consis

19、ting of a surfactant containing at least 90% d-limonene.
