19、or surfaces of steel enclosures of outdoor-use electrical equipment for protection of themetal against atmospheric corrosion.1.2 These requirements cover organic coatings consisting of one or more coats and their system ofapplication to steel or zinc-coated steel with specified pretreatment, applica

20、tion, bake or cure schedule,and minimum dry-film thickness.1.3 The final acceptance of a coating is dependent upon its use in a complete product that complies withthe requirements in the standard applicable to such a product.1.4 The requirements may be applied to other organic or nonmetallic coating

21、s if found to be appropriate.1.5 The flammability or toxicity risks associated with the coating materials in any form, or the acceptabilityof the materials for uses other than indicated, are not within the scope of these requirements.1.6 A product that contains features, characteristics, components,

22、 materials, or systems new or differentfrom those covered by the requirements in this standard, and that involves a risk of fire, electric shock, orinjury to persons shall be evaluated using the appropriate additional component and end-productrequirements as determined necessary to maintain the acce

23、ptable level of safety as originally anticipatedby the intent of this standard. A product whose features, characteristics, components, materials, orsystems conflict with specific requirements or provisions of this standard cannot be judged to comply withthis standard. Where considered appropriate, r

24、evision of requirements shall be proposed and adopted inconformance with the methods employed for development, revision, and implementation of this standard.2 Glossary2.1 For the purpose of this standard, the following definitions apply.2.2 APPLICATION METHOD The procedure and equipment employed in

25、applying the coating, whichmay also include parameters of equipment operation.2.3 BAKE OR CURE SCHEDULE The time-temperature conditions used following the application ofan organic coating.2.4 ORGANIC COATING A coating containing drying oils, resins, and setting or hardening agentssuch as reacting ch

26、emicals and catalysts or resins.2.5 PRETREATMENT The cleaning or chemical process, such as iron or zinc phosphating, used onthe metal surface prior to application of the organic coating.2.6 SUBSTRATE The specific metal surface to which the organic coating is to be applied.FEBRUARY 9, 2005UL 13324UL

The first stated value is the requirement.4 Undate

28、d References4.1 Any undated reference to a code or standard appearing in the requirements of this standard shall beinterpreted as referring to the latest edition of that code or standard.PERFORMANCE5 Specimens for Test5.1 Specimens representative of the coating system are to be employed in these tes

29、ts. The sheet steelused in the preparation of specimens of the coating is to be representative of the steel for which thecoating is intended, with respect to composition and surface conditions. The specimens are to beprepared by the same procedures of surface cleaning, pretreatment, application of t

30、he coating system,drying or curing, and minimum dry-film thickness that will be used in the end-use product.5.2 If a coating system is intended to be used in a range of colors, specimens representing the range areto be tested. Specimens with the highest pigment to vehicle or resin ratio, lowest pigm

31、ent to vehicle orresin ratio, and metallic pigment are to be tested. If specific color pigments are known to have unusual orcritical properties, they are also to be tested.5.3 Test specimens are to be 4 inches (102 mm) wide and 12 inches (305 mm) long, with the thicknessof the base metal being repre

32、sentative of that in the end-use application.6 Specimen Preparation6.1 The edges or bare surfaces of all specimens are to be covered with moisture-resistant tape orcompound. Two of the specimens are to be scribed in accordance with the Method for Evaluation ofPainted or Coated Specimens Subjected to

33、 Corrosive Environments, ASTM D1654-92. A single 8 inch(203.2 mm) diagonal V-cut scribe running lengthwise across the specimen is to be used. The scribe is tobe free of burrs and is not to contact the edges. The scribing tool used is to be either:a) A carbide tipped tool Style E, with 1/64-inch (0.4

34、-mm) nose radius, orb) A carbide tipped tool ground to a single point having an included angle of 60 15 degrees.FEBRUARY 9, 2005 UL 1332 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM UL7 Salt-Spray (Fog) Test7.1 Two scribed and two unscribed
