1、Designation: E3020 15Standard Practice forIgnition Sources1This standard is issued under the fixed designation E3020; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the

2、year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice describes a series of ignition sources thathave been used and that are potentially applicable to assessingfire-test-response characteristics resulting from t

3、he ignition ofmaterials, products, or assemblies.1.2 This practice does not identify which of the ignitionsources described is applicable to any specific use since that isa function of the associated fire hazard (see also 5.2).1.3 This practice is not necessarily comprehensive and it ispossible that

4、 other applicable ignition sources exist (see also5.3).1.4 This practice describes both flaming and non-flamingignition sources, since the outcome of a non-flaming ignitioncan be the eventual flaming ignition of these materials orproducts (see also 4.2).1.5 This practice does not provide pass/fail c

5、riteria that canbe used as a regulatory tool.1.6 This fire standard cannot be used to provide quantitativemeasures.1.7 Fire testing is inherently hazardous. Adequate safe-guards for personnel and property shall be employed inconducting these tests.1.8 This standard is used to measure and describe th

6、eresponse of materials, products, or assemblies to heat and flameunder controlled conditions, but does not by itself incorporateall factors required for fire hazard or fire risk assessment of thematerials, products, or assemblies under actual fire conditions.1.9 This practice contains notes and foot

7、notes which pro-vide explanatory material. These notes and footnotes (exclud-ing those in tables and figures) shall not be consideredrequirements of the standard.1.10 The values stated in SI units are to be regarded asstandard in referee decisions.

Terminology3.1 Use Terminology E176 or ISO 13943 for definitions ofterms used in this test method and associated with fire issues.Where differences exist in definitions, those contained inTerminology E176 shall be used.3.2 Definitions:3.2.1 ignition, nthe initiation of combustion.3.2.1.1

37、 DiscussionThe combustion may be evidenced byglow, flame, detonation, or explosion. The combustion may besustained or transient.

38、 of ignition, na discrete source of energy,such as, for example, a flame, spark, electrical arc, or glowingwire (compare piloted ignition, unpiloted ignition). E1763.2.4 smoldering, ncombustion of a solid without flame,often evidenced by visible smoke.3.2.4.1 DiscussionSmoldering can be initiated by

39、 smallsources of ignition, especially in dusts or fibrous or porousmaterials, and may persist for an extended period of time afterwhich a flame may be produced. E1763.2.5 spontaneous ignition, nunpiloted ignition caused byan internal exothermic reaction (compare piloted ignition).E1763.2.6 sustained

40、 flaming, nflame on or over the surface ofa test specimen that lasts longer than a defined period of time(contrast transitory flaming).3.2.6.1 DiscussionTypically, the same defined period isused to define “transitory flaming.” See the specific standardtest method for applicable defined period of tim

41、e. E1763.2.7 transitory flaming, nflame on or over the surface ofa test specimen that does not last longer than a defined periodof time (contrast sustained flaming).3.2.7.1 DiscussionTypically, the same defined period oftime is used to define “sustained flaming.” See the specificstandard test method

42、 for applicable defined period of time.E1763.2.8 unpiloted ignition, nignition caused by one or moresources of energy without the presence of a pilot source ofignition (compare piloted ignition, spontaneous ignition). E1764. Summary of Practice4.1 This practice describes a series of standard ignitio

43、nsources used in test methods, specifications, or regulations toassess fire-test-response characteristics of materials, products,or assemblies.4.2 These ignition sources include those that assess theresponse to non-flaming ignition sources, including smolderingcigarettes, glow wires, hot wires, and

44、radiant heat sources.4.3 These ignition sources include those that assess theresponse to flaming ignition sources, including both premixedflames and diffusion flames.4.4 This practice does not offer pass/fail criteria.4.5 The information included in this practice is representa-tive of the ignition s

45、ources in the various standards at the timethis practice was written. Users of this practice are encouragedto consult the latest edition of any standard at the time ofproposed use of an ignition source.5. Significance and Use5.1 A variety of standard test methods, specifications, andregulations have

46、 been issued by a number of different standardsdeveloping organizations and regulatory authorities that con-tain ignition sources used to assess fire-test-response charac-teristics associated with flaming and non-flaming ignition. Thispractice describes such ignition sources and provides informa-tio

47、n on the standard method in which they are described.5.2 The ignition source to be chosen for any specific useneeds to be relevant to the fire hazard associated with theintended application. Neither the scope of the standard con-taining the ignition source nor any other aspect of the standardhas any

48、 bearing on the use of the ignition source for anotherapplication.5.3 This practice is not expected to be a fully comprehen-sive list of ignition sources. If additional ignition sources areidentified they can be added to the practice.7Available from Underwriters Laboratories (UL), 2600 N.W. Lake Rd.
