2、 January 23, 2017 NOTICE EIA Engineering Standards and Publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtainin
3、g with minimum delay the proper product for his particular need. Existence of such Standards and Publications shall not in any respect preclude any member or nonmember of ECIA from manufacturing or selling products not conforming to such Standards and Publications, nor shall the existence of such St
4、andards and Publications preclude their voluntary use by those other than ECIA members, whether the Standard is to be used either domestically or internationally. Standards and Publications are adopted by ECIA in accordance with the American National Standards Institute (ANSI) patent policy. By such
5、 action, ECIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication. This EIA Standard is considered to have International Standardization implications, but the International Electrotechnical Commission activity
6、has not progressed to the point where a valid comparison between the EIA Standard and the IEC document can be made. This Standard does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Standard t
7、o establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use.

Figure 1 - Test setup 45 Holding fixture Test specimen Free end Burner EIA-364-81A Page 6 4.6 The test flame shall be applied for 10 seconds, unless otherwise specified in the referencing document. 4.6 1 After the 10 seconds application th
9、e test flame shall be removed a minimum of 152 millimeters (6 inches) from the point of application. 4.6.2 In the event of flaming or glowing of the test specimen, the duration of said flaming and glowing shall be noted and recorded. Dripping of molten and/or flaming material and igniting of the lay
10、er of cotton, if occurring, shall be noted and recorded. 4.6.3 To distinguish between flaming and glowing, a small piece of surgical cotton (50 millimeters square) shall be brought into the area in question. Ignition of the cotton shall be indicative of flaming. 4.7 The flame shall be reapplied for
11、10 seconds in accordance with 4.5 and 4.6. The flame shall be immediately applied after the first application or when the flaming or glowing ceases to exist, if occurring on the first application. 4.8 If the test specimen drips molten and/or flaming material during the flame application, the burner
12、may be tilted to an angle up to 45 degrees and slightly removed to the specimen side to avoid material dripping into the burner tube. 4.8.1 The 9.5 millimeters (0.38 inch) distance between the bottom of the test specimen and top pf the burner tube shall be maintained. 4.8.2 Any molten “strings“ of m
13、aterial are to be ignored and the flame is to be applied to the major portion of the specimen. 4.9 Charring, melting etc., of the test specimen shall be ignored. 5 Details to be specified The following details shall be specified in the referencing document: 5.1 Configuration to be tested 5.2 Conditi
