13、TIONAL STANDARD Approval of an American National Standard requires verification by ANSI. ANSI states that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standar
14、ds Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means significantly more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and a concerted effort be made toward
15、 their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether they have approved the standards or not, from: manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the s
16、tandards. The American National Standards Institute does not develop standards, and will under no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of t
17、he American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. Caution Notice: This American National Standard may be revised or withdrawn at any time. The procedures of the American Nati
18、onal Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute. Published by National Electri

27、 Luminaires, general requirements, and tests, Section 9, “Resistance to dust, solid objects and moisture.” Tables 1, 2, and 3, in particular, are based on IEC 60529. The type of protection covered by this standard is as follows: a) Protection of persons against contact with, or approach to, energize
28、d electrical components inside the light fixture (luminaire) enclosure, and protection of the equipment against ingress of solid foreign bodies b) Protection of equipment inside an enclosure against harmful ingress of water, solid foreign objects or dust It should be noted that the IP rating of a lu
29、minaire has no bearing on its Dirt Depreciation characteristics. Testing is performed on new luminaires and is not an indicator of the life or reliability of the luminaire during its service life. Some components such as seals and gaskets deteriorate over time with exposure to heat and the environme
30、nt and should be evaluated separately. 2 INFORMATIVE REFERENCES This standard is intended to be used in conjunction with the following publications. The latest edition of the publication applies (including amendments). IEC 60529, Edition 2.1, Degrees of protection provided by enclosures (IP Code) IE
31、C 60598-1, Edition 7, Luminaires Part 1: general requirements, and tests, Section 9, “Resistance to dust, solid objects and moisture.” 3 DEFINITIONS Degrees of protection: The extent of protection provided by a lighting fixture (luminaire) enclosure against ingress of foreign objects or water, verif
32、ied by standardized test methods. Direct contact: Contact of persons with energized components. Enclosure: A part that provides protection of equipment against external effects and direct contact. Hazardous live part: A part that, when energized, presents a danger to human touch. Hazardous part: A p
33、art that presents a danger to human touch. IP code: A coding system to indicate the degree of protection afforded by a lighting fixture (luminaire) enclosure against ingress of foreign objects or water. ANSI C136.25-2013 Page 2 Copyright 2013 by National Electrical Manufacturers Association Opening:
34、 A gap or aperture in an enclosure that exists or may be formed by the introduction of a test probe. Probe, access: A test probe simulating a part of a person or tool to verify the possibility of ingress into an enclosure. Probe, object: A test probe simulating a foreign object to verify the possibi
35、lity of ingress into an enclosure. Protection provided by an enclosure against access to hazardous parts: The protection of persons against contact with hazardous parts or hazardous live parts. This protection may be provided by the enclosure itself or by means of barriers as part of the enclosure,
36、or distances inside the enclosure. 4 DESIGNATION OF PROTECTION The degree of protection provided by an enclosure is indicated in the IP code in the following manner: Code letters IP (Ingress Protection) First numeral 0 6 (dust or foreign objects) Second numeral 0 8 (moisture) The first numeral shall
37、 indicate the degree of protection provided by the enclosure against human contact or object held by a person that could contact a hazardous part, and simultaneously, the protection of the equipment against the ingress of foreign objects, including dust. An enclosure shall only be designated with a
38、stated degree of protection indicated by the first numeral if it complies with all lower degrees of protection. The second numeral shall indicate the degree of protection provided by the enclosure against the harmful effects of the ingress of moisture. Where a numeral is not required to be specified
39、, the letter X shall replace it. When an enclosure (luminaire) provides different degrees of protection for different mounting arrangements, the relevant information shall be indicated by the manufacturer in the instructions and/or label related to the respective mounting arrangements. 5 DEGREES OF
40、PROTECTION AGAINST ACCESS TO HAZARDOUS PARTS (FIRST NUMERAL) The first characteristic numeral of the IP Code number indicates compliance with the following tests for the degree of protection against access to hazardous parts. It also indicates compliance with tests shown in the next section for the
41、degree of protection against solid foreign objects. The protection against access to hazardous parts is satisfactory if adequate clearance is kept between the specified access probe and hazardous parts. Lighting equipment operates at voltages below 1,000 VAC. For voltages less than 1,000 VAC, the ac
42、cess probe must not touch the hazardous live parts. For luminaires operating at voltages exceeding 1,000 VAC, when the access probe is placed in the unfavorable position(s) (positions where the probe is closest to un-insulated current-carrying parts), the equipment shall be capable of withstanding t
43、he dielectric tests as specified in the relevant product standard applicable to the equipment. ANSI C136.25-2013 Page 3 Copyright 2013 by National Electrical Manufacturers Association The maximum voltage should be considered when the dielectric test voltage and adequate clearance are determined. Des
44、cription of the tests is shown in Table 1.

48、ic numeral of the IP Code indicates compliance with tests for the degree of protection against access to hazardous parts as described in Section 5, and compliance with tests shown in Table 2 for the degree of protection against solid foreign objects and dust. The protection against ingress of solid
49、foreign objects/dust implies that the full diameter of the probe shall not pass through an opening in the enclosure. Object probes for numerals 3 and 4 shall not penetrate the enclosure at all. Dust protected enclosures to numeral 5 allow a limited quantity of dust to penetrate under certain conditions. Dust tight enclosures to numeral 6 do not allow any dust to penetrate.
