4.2 When testing, the requirements of sections 4, 7, 8 of GOST 30630.0.0 are taken into account.
4.3 Before and after testing (and if it is established in the regulatory documents (hereinafter referred to as RD) for the product, then during the testing process) the product must be subjected to an external examination and its parameters must be measured in accordance with sections 4, 7, 8 of GOST 30630.0 .0, in particular - product parameters that determine safety.
It shall be specified whether the product is tested in operation, in the non-operating condition or in the ready-to-use condition. At the same time, for ERI and other products operating with their connection to power supplies, the conditions for checking the electrical strength of the product insulation are specified. In addition, for such a product should not be:
- accumulation of water on electrically insulating parts, where water can cause tracking (formation of conductive traces) on creepage paths;
- ingress of water on live parts or on windings not designed to operate in a wet state;
- accumulation of water near the cable glands and (for electrical products) terminal box or penetration into the cables.
In order to most accurately reproduce the operating conditions in terms of the impact of water in the ND on the product, the procedure for measuring the parameters of the product after testing should be specified: whether the parameters, or part of the parameters of the product, should be measured, as well as before or after they dry.

7.4.2 The product (if necessary, mounted in the layout of the corresponding part of the complete product) is placed under the sprinkler, which has a diameter of holes for water passage of 0.4 mm. The method of placing the product under the sprinkler is determined by the RD for the product. The rain zone should overlap the overall dimensions of the product by at least 30 cm. The direction of rainfall should be an angle of 45 ° with the plane of the product, the water temperature at the initial moment of testing should be at least 10 °C lower than the temperature of the product.
7.4.3 The product is exposed to rain for 2 hours at an intensity of (5 ± 1) or (3 ± 1) mm / min, depending on the requirements for the product in accordance with its climatic design according to GOST 15150. During this time, if specified in the RD for the product, the checks specified in the RD for it are carried out.
The product is periodically rotated by 90° around an axis perpendicular to the plane of the product. A product designed to work in a certain operating position is rotated every 30 minutes. The product, designed to work in any operating position, is rotated every 15 minutes, and after each hour of testing it is rotated 180 ° relative to the plane of the product. It is allowed to interrupt the tests for the time of rotation of the product. Instead of turning the product, it is allowed to turn the sprinkler. It is recommended to install the product on a base that allows the product to rotate around the vertical axis at a frequency of one rotation per minute.
7.4.4 Rain intensity is measured using a cylindrical water collector with a diameter of 10-20 cm and a depth of at least half the diameter.
Rain intensity is measured about the axis of the object (or part of the test part), as close as possible to the object, but in such a way that reflected water drops do not fall into the trap. Measurements are taken at the top, middle and bottom points of the object, or only at the middle point if the height of the object is less than 100 cm. The sump should be moved up and down near the measurement point. When testing objects with horizontal dimensions greater than 2 m, measurements should be made in two or three places in the horizontal plane, and in each of these places - at the top, middle and bottom points of the object or only at the middle point.
The values measured for each of the points should not differ by more than 25% from the average value.
The average value of all measurements of the vertical component of rain is taken as the value of the rain intensity during the tests.
7.4.5 The product is removed from the chamber and wiped, opened, subjected to visual inspection and its parameters are measured in accordance with 4.2.
7.4.6 In the RD for the product, the procedure for testing that differs from that established in this standard may be established.

EXPLANATION TO SOME TERMS
1. External influencing factor Regulatory and technical documents (NTD) consider external influencing factors that cause a limitation or loss of the operable state of products, i.e. exerting on them harmful effect, although in some cases they can increase the working state, for example, low temperatures improve the performance of refrigeration units. 3 . Nominal value of WWF For the nominal values of WWF, normalized changing or unchanged upper and lower values of WWF are taken. In the NTD, among the nominal values of the VVF, you can also set working and limiting working values. Limit operating values of VVF - VVF values within which products can rarely be in operation and must: accuracy and nominal parameters, if these deviations occur); b) restore the required accuracy and ratings after the termination of these operating limits. 10. Mechanical shock Mechanical shock can be of single and multiple action. A variation of mechanical impact is a ballistic impact. Ballistic impact - impact of the body when it meets an obstacle in the process of ballistic flight. Ballistic flight is the flight of a body that occurs in the absence of aerodynamic lift. 18. Rolling Distinguish between rolling (angle of inclination) and vertical (periodic vertical movement to the earth's surface). 12. Roll The term "roll" is most often used in relation to ships and aircraft. 20 Trim Trim is eliminated by redistributing loads along the length of the product (in ships, by redistributing ballast water). 20s. Mechanical pressure Mechanical pressure can be of the following types: hydraulic, pneumatic, light pressure, gas medium pressure. 26. Dynamic (th) dust (sand) Dynamic (th) dust (sand) has an abrasive effect on products and materials. 29. Corrosive-active agent of the soil-soil environment Soil - rocks of the Earth, which are the object of human engineering and construction activities. 35. Fouling Foulers are aquatic organisms (animals and plants of sea and fresh waters) that settle on stone structures, underwater parts of ships, buoys, port and other hydraulic structures, inside the surface of water systems, water intake pipes, on submarine cables, etc. ., reducing the speed of ships, reducing the flow of water in water pipes, reducing the efficiency of cooling devices and contributing to the corrosion of metal and concrete underwater structures. 45. Laser radiation Stimulated radiation - coherent electromagnetic radiation that occurs during forced transitions (coinciding in direction, frequency, phase and polarization with stimulated radiation).INFORMATION DATA

5.6.3 Not listed in and testing of packaging (containers) without products is carried out as required by the standards for the corresponding packaging (container).
5.6.4 Before and after testing, an external inspection of the package is carried out. The package is considered to have passed the test if it has no damage indicated as unacceptable in the RD and (or) TD for the package.
The product is considered to have passed the test for the impact of mechanical factors during transportation if, after testing, no mechanical damage was found during external examination, and the parameters of the product meet the requirements established in the standards and specifications for products for this type of testing.
B.1 IEC 60068-2-48 (hereinafter referred to as the IEC standard) contains qualitative descriptions of the processes that can occur during long-term storage of products, examples of the possible deterioration of the properties of products (mainly electronic products and electronic equipment) when they are stored in a warehouse, during long-term installation or operational storage (standby operation). The IEC standard also contains qualitative descriptions of the possible differences between processes occurring during actual storage and those occurring during testing by the methods specified in other IEC 60068 series standards.
Combining conditions in the IEC standard warehousing and installation with the conditions of operational storage when describing the processes of deterioration of the properties of products is incorrect. In the first two cases, the products are fully or partially protected by packaging and (or) a temporary anti-corrosion coating, which slows down or modifies the processes of deterioration of the properties of the products. In the case of operational storage, this protection is not available; this case is not within the scope of this standard.
The IEC standard does not contain data on the impact of packaging and temporary anti-corrosion protection on the described processes, data on assessing the quality of packaging; the latter contains this standard.
The IEC standard does not provide guidance on the use of specific IEC 60068 test methods to evaluate product shelf life or packaging performance. Thus, the IEC standard does not provide data on the quantitative parameters of test modes, quantitative ratios or restrictions for constructing test modes.
B.2 The IEC standard states that it is impossible to build a unified methodology for assessing the shelf life of various products and does not mention the possibility of at least creating principles for constructing such a methodology. This statement contradicts recent works in this area, applied in a number of RDs (for example, GOST R 51369, GOST R 51372, GOST R 51802), including in this standard (see).

9 Testing
The specimen (with the abraded surface up) is fixed in such a way that it does not move during the test. The device is set in motion. The lever with a felt nozzle is lowered onto the sample perpendicular to its surface and a load (4.0 ± 0.4) N is applied. The abrasive effect on the sample lasts until the specified number of steps is reached in accordance with the regulatory specific view glass. At least four tests (abrasive impacts) are carried out on the sample, each of which corresponds to a given number of steps. For each test (abrasion) a new felt pad is used. General form the location of the traces after the abrasive effect on the sample is shown in Figure 2.
