3.5 The environmental conditions for the use of various types of electrical protection products shall comply with the provisions of Tables 1 to 5. If special use conditions are required, the order form can be negotiated with the manufacturer to produce other environmental integer levels specified in B/T4375-1999 to replace the equivalent specified in 3.3 of this standard. 36. The cooling water volume and temperature of water-cooled lighting products can be specified in the technical conditions of the product standard according to the actual situation, or determined by negotiation with the supplier. 4 Requirements

The insulators and porcelain bushings used shall be reinforced insulation or pollution-resistant products. If necessary, products with a higher rated voltage can be selected:
4.4 The shell protection level of electrical products shall not be lower than IP53 specified in GB4208. There are four levels of IP53, IP54, IP55 and IP65. In special cases, other levels can be selected. 4.5 After various types of electrical products are tested for external protection, in addition to complying with the provisions of GB4208. The following requirements shall be met: a) After the dustproof test. No sand or dust should enter the bearing; b) After the waterproof test, no water should enter the junction box, bearings and stop 1. 4.6 Medium and large electrical products can be equipped with preheaters to prevent the machine from overheating. The insulation structure and treatment process of the products equipped with heaters should be similar to those of household products without heat, but the insulation part can be exempted from the wet heat test. The surface protection layer such as paint and wool can be tested: the selection of the heat power of the heater is generally designed to make the space temperature near the protective part of the product at least 3K higher than the outside air temperature. The setting of the heating end should not exceed the heat resistance allowable temperature of the surrounding area; 4.7 Indoor and outdoor electrical products with strong corrosion protection should be subjected to carbon dioxide according to GB 2423.33. The quality of the gas and other tests are qualified requirements.
47.1 The insulation resistance of windings or live parts to the machine and between each other shall meet the following requirements: a) For anti-isolating motor products with rated voltage below 500V, the insulation resistance shall not be less than 1MQ; for motors above 500V, the insulation resistance shall not be less than 1MQ:
Where: R——insulation resistance of the winding or live parts to the machine and between each other, M: I——rated voltage of the motor unit, V6) For anti-isolating electrical products, the insulation resistance shall not be less than 2M0: R
c) For other anti-isolating electrical products, please refer to the requirements for motors and electrical products or specify separately. 4.7.2 The insulation of anti-electromechanical products should be able to withstand the same power frequency withstand test voltage value as specified in the plastic product standards. 4.7.3 The disconnecting action value and the high fever temperature should be in accordance with the relevant basic product standards or technical requirements:
4.7.4 External requirements:
a) The insulating material should not show delamination, blistering, softening and sticking. b) The sealing of plastic parts should not show corrosion, delamination, blistering, deformation, cracking, running and sticking. The characters on plastic nameplates and signs should be clear and should not fall off. The organic coating on the outer surface of the metal should not show looseness or obvious delamination, except for the gaps between the metal parts, frost particles on the surface of the banknotes and mechanical impact. The paint layer should not show less than 1 degree of gas leakage. The diameter of individual fire bubbles should not exceed 10mm for motor products and 8mm for electrical appliances. The number of stainless steel parts, self-controlled parts and chemically treated parts with corrosion and magnetic recovery area accounting for 5%-25% of the main surface area of the parts should not exceed 5
JB/T 9535-1999
More than 30% of the total number of parts, but the corrosion area of individual parts is allowed to exceed 25%; d) There should be no obvious corrosion (especially hooking and rust) on thick electrical and magnetic parts, components and auxiliary parts inside the enclosure, and there should be no deterioration of grease.
4.8 External type (north face W) electrical products should have light magic fire resistance. After 12 cycles of air-change heat test conditions specified in 5.1 of this standard, the insulation performance should meet the assessment requirements specified in the corresponding damp heat type electrical product standards, or as specified by professional product technical conditions. After the strong heat test, the product should be inspected for appearance, and its quality level should be graded according to the ≤.4 method in IB/T4159-1999. The purpose of the external inspection before the heat test is specified in the professional product technical conditions, 4,9 Outdoor electrical products should have certain micro-performance. If the microorganisms have an impact on the performance of the product or the product has appearance requirements, it is necessary to conduct long-term tests and assessments on the components that may be affected by the microorganisms in the product. The qualified standards of the tests are specified by the relevant product standards: For indoor and outdoor electrical products with frequency protection of W1, WF2, F1, and F2, the impact of the downward movement is not very important compared with the impact of chemical exposure, so this sub-category of products does not undergo long-term tests and assessments. 5 Test methods and inspection rules
5.1 Electrical products for protection against external factors must pass the relevant artificial simulated environment test assessment.
