3. 1 Comparison with GB/T 4798. 1 General description of C:13.T17!8.1 The environmental conditions to which the product may be exposed during storage are classified and graded into environmental parameters. The parameters in these levels can be given separately, but the product may be exposed to them from time to time: some of these parameters are independent of each other, while some parameters are closely related. For example, radiation and temperature. 3.2 General explanation of GB/T 2423 GB/T 2423 establishes a series of environmental test procedures to use appropriate test severity levels. The choice of test severity level depends on the product's failure characteristics: two types of products can be placed in various places with the same environmental level, but with different failure consequences. One product may be tested under more severe conditions than the other. This part only gives the conventional failure consequences; for serious failure consequences, the test severity level must be increased based on the expert's understanding of the product. 3.3 Severity level GB/T 2423 sets out the level of environmental conditions that the product can be exposed to for a short period of time. The probability of exceeding this level is relatively small: the recommended test severity levels given in each specification of this part take this into account. For more information, please refer to IEC G0721 4 3. That is, IEC 6072--2, 3. 4 Recommended tests
There are two types of tests in the table below. The first test lists the test of B24: Use the severity level closest to the recommended or tested test. The second type of test is the test method and severity level recommended in this part, which is generally considered to be applicable to most electrical and electronic products. 3.5 Storage level environmental test
(R/T1798. [The environmental parameter group and severity level to which the product and its packaging (if any) are subjected during storage are classified. This classification does not include transportation during storage. If possible, the product should be tested under normal storage conditions. For example, if the product is packaged, it should be tested with the packaging. If the product can be stored with or without packaging, it is necessary to test both conditions. For some tests and products, it may be more suitable to test with packaging than without packaging. Severe. For example, products that are taken out of sealed packaging may produce condensation when the temperature changes. The classification does not include the environmental conditions produced by being squeezed in a closed environment. 3.6 Test duration || tt || The test durations in Tables 1 to 8 are selected based on experience. Experience has proven that these durations are sufficient to show the impact of the environmental conditions on most products. However, if verified by specific applications, users can change these values. In order to facilitate user understanding, the relevant notes in the tables in this section explain why the durations are selected. 3.7 Ambient environment || tt || The term "ambient environment" used in some recommended tests refers to the standard atmospheric conditions specified in 5.3.1 of (13/T2121-1999). That is: temperature 15--35℃, relative humidity 25%-~75%, and the maximum absolute humidity 22 g/1n, air 86 kPu~-10% kPa.TS()2533 and its appendix provide detailed corrections of standard atmosphere 1EC61721-2-3 only provides an outline.

) The information shown in the climatogram is used to illustrate the selection of relevant tests under climate conditions. There is no climatic separation in GH/T4798.1. In order to test the performance of products to withstand the service conditions of the climate diagram, only the following three tests are used: high temperature test, in which the relative limit should not exceed 50%, but it is difficult to accurately control: low humidity test, without controlling the resistance:
constant condensation heat test, controlling the temperature and humidity
in the table, these tests are represented as test x, machine 7, and the other extreme conditions in the climate diagram do not require testing, and the above (there is no ready-made test in B/12423
2) The test temperature is equal to the environmental parameters of B3/1798.1, and the holding time is 15h.For most products, it is sufficient to show that it is designed to withstand the temperature. When evaluating the thermal effects of radiation or thermal radiation (see 8 below), it is recommended to extend the duration of GH/T2123.2 by 72 hours. The test duration is consistent with the environmental parameters and the same as in 11/T738.1 for this level. Since the material undergoes less physical or chemical changes when it reaches the low temperature state, the recommended duration of 16 hours is sufficient for low temperature tests. For small products with low thermal inertia, it can be reduced to 2 hours. These "cooling levels" are closest to GH/212 3 is the preferred value. Differences in temperature and humidity conditions are small and not significant, and are within the measurement tolerance range. However, for most products, this is sufficient to show that the product is designed to withstand this temperature.) Overflow tests often require narrow test designs. This variation range is not important. However, in this grade, the temperature range is too small to cause a lake. Except for airtight products, this test should be omitted. For airtight products or some products that store/expose liquids, GH/T is recommended. 2123.21 Test M. For formal applications, when evaluating the effect of air pressure on components of grade 61, there is no inference test, no inspection method under this clause in B/T 2123, and this condition is within the standard condition range defined in GH/1 2221: therefore, it is technically unsuitable for most products to be degraded, and no difficult test is provided. 8) Test C for the effect of solar radiation on the simulated ground in the pilot specification of 1 2423.24 is for other products; continuous radiation, therefore: it is sufficient to assess this degradation effect. Although the temperature level of this grade is 70W/m2, H is only (GI3: Test Sn in T 4798.1 case 1 solar radiation value of 1 120W/m .
Since it is difficult to accurately test the actual radiation, the radiation test is not recommended. It is recommended to use a temperature increase of 10°C to evaluate the case, and to evaluate the photochemical reaction of materials and components. For information on the historical rate, please see Tx604:--. 9) No test is recommended. G1/T+7?8. "There is no ready-made thermal radiation test. This effect is included in the humidity test. For products installed near high heat radiation, special protective measures such as heat shields, insulation layers or additional high current tests may be required. The degree of temperature increase depends on the severity of the heat source.
) There is no recommended test, no suitable (B/T2423 test, this test is mild for most products, such as special conditions 11 or 171, or protective measures, especially for large products. If this condition is to be evaluated, the user must develop his own evaluation method.

1) The information displayed in the climate diagram is the selected and relevant test signature for the climate conditions. (: B/T47SR [There is no climate chart. In order to test the performance of the product under the conditions in the climate chart, usually only the following two tests are used; 1. High temperature test: the humidity does not exceed the control humidity, and the package is not evaluated. 2. Low humidity test + no humidity control agent:
pull fixed humidity and heat test, control the humidity and mix. In the table, these tests are represented by test × and. Other boundary components of the climate chart are not required or monitored, and formula B1423 has a ready-made test containing muscle,
2) The test concentration is closest to the optimal light value of GB/T 3423. 2. It is recommended to test humidity to. 15X to anti-dirty (the conditions of this level in B/T 4798.1, the duration is selected as 16 hours. For human image products, it can indicate that it is designed to withstand any temperature without any difference. It is necessary to evaluate the thermal effect of axial radiation or thermal radiation (note 8 below)), and the duration of GB/T 2123.2 can be extended to 72h. 3) The test temperature is the same as that of the environment in GB/T 4726. When the material is in a low temperature steady state, it will rarely undergo physical or chemical changes. For low temperature tests, the recommended duration of 1h is sufficient. For products with lower heat dissipation, it can be reduced by 21.4. This severity level is closest to the severity level in GB2423. The differential difference of wet printing conditions is not obvious. For most products, the test tolerance range is within the tolerance range. The short duration can fully show that the design of the engineer is sufficient to withstand the temperature. 5) Temperature change tests are often required to test the tolerance of the equipment. The range is not important. However, in this level, condensation may occur. Therefore, a temperature range of u℃ is provided to allow condensation to form on products with low heat dissipation. G3/1 4798.1 The temperature change rate specified in CB/T2:23.22 is 0.5:/min+ and the minimum recommended rate for this grade of product is 1V/:im. 6) For sealed products or some products that store/handle liquids, GH/T3123.21 test M shall be used. For the evaluation of the effects of qi deficiency at the component level, there is no recommended test. There is no test method under the conditions in GB3T2138 (7). This condition is within the standard conditions defined in (3/T2:211, because it is suitable for most products. There is no push-flower test) The simulation in the test plan of sample selection 2.21 is also a test before the test of 1, because it produces 1 continuous radiation, so the effect of light degradation can be calculated. Although the severity level of this level is W/min, (H/T 2798. 1 The test condition is a solar radiation value of 1 120 W/in
Due to the difficulty in tracking the actual radiation at the point of change, the solar radiation test is not ideal. It is recommended to evaluate this condition by increasing the temperature of the high temperature test and evaluate the chemical reactions of materials and components. For more information, refer to [FEC 60?4:4 05) There is no recommended test. B/I47S.1 has a thermal gradient test, and its products are usually included in the market temperature test. For products near the heat source, special protective measures may be required, such as heat protection shields, insulation layers, or additional high temperature tests. The temperature is determined by the severity of the heat source.
13) There is no push test, no suitable (B/T2223 test, this condition is generally suitable for most products. If special conditions (123 or 17) are required, they must be adopted. For large products, if this item is to be evaluated, you must develop your own evaluation method. 11) Select a unique severity level to reflect the typical storage environment in the market. See 12). 12] If there is recent evidence, the user must select one of the following conditions from 125, 176 and 127: Then the user must select the appropriate test method from G13/2223,33 for the duration and test severity level. As a guide, the following points can help the user choose the appropriate test method. Flowing water. If the product is usually rainproof and can record the dripping or seepage water from above, then CRT2423.3R test R2.2: Wetting water test is the preferred test method, drip height 3m, tilt angle 0°, duration 11. Splashing water: If the product can splash through the sprinkler system or water wheel, G3712423.38 test R2.1-drifting pipe method or R12.2-draining water method. 1min/m, maximum 30min is the preferred method. Water spray: If the product has the ability to be protected from flushing or washing, FT242.88 test R3...: hose method is the preferred square head. l) Water jets: If water jets are likely to hit the product, select (iLT2128. Test Ra or Test Rb to indicate that the product is designed for these conditions.
13) Except for the low temperature test (test A6/Ad>, there are no appropriate tests in B/T 2123: This condition should be taken into account when designing products for this level.

GH/T ?28.1 has a comparative gas chart, in order to test the performance of the product under the gas chart, only the following three test items are used: knock filter test, which requires the selection of low humidity, and the humidity is not controlled unless it is properly controlled!
Specified mixed heat test, controlled temperature and humidity,
These tests are indicated in the table as test ×z, steam recovery, and other boundary conditions are not required for testing, but H/T 2423 has a ready-made test
test delay and CB/T -17I8,! The same as the environmental parameters of this level. The selected duration is 16:;. For most heat dissipation products, it can fully show that its design allows it to withstand this temperature. To evaluate the thermal effects of excessive radiation or thermal radiation, see the following notes, it is recommended to extend the duration of GR12423.2 to 72
3 test temperature (13478.1. The environmental parameters of this grade are similar. Since the material will rarely undergo physical or chemical changes once it is inverted to a low temperature steady state, the recommended duration of the low temperature test is 16 hours, which is sufficient for the small products with low thermal conductivity. This severity level is the most important for the severity level in H/2123. The slight difference between temperature change and temperature condition is not significant. In normal measurement and use, the duration is 96 hours. For most products, it can be said that the design is sufficient to withstand the temperature. 5) Temperature change tests often require that the test design tolerance range is not important. However, in this grade, the condensation function proposes a temperature range of 0 to allow low thermal conductivity products to form condensation. (The standard condensation rate in /T 1798, 1 is 0,000 mil, but the minimum recommended condensation rate for this grade of products in GB:T 2423.22 is 17-17m. 6) For sealed products or storage! For products that handle liquids, it is recommended to carry out (3/T 2423,21 or M. For formal applications, there is no recommended test when determining the influence of atmospheric pressure at the component level. 7) There is no test piece method under this condition in CJ/T 2123. This condition is within the standard atmospheric condition range defined in (B/1 2:21, so it is suitable for most products. There is no recommended test. 8) Select, 13/1 2423. 24 in the test procedure of test C simulating the influence of solar radiation on the ground is four because it produces continuous radiation, so some rivers can evaluate the effect of photodegradation. The severity level of this level is 1120W/nY, which is consistent with the test conditions of test Sa included in 11/T23.24. It is difficult to reproduce the actual radiation that is actually endured. The high temperature radiation test is not ideal: it is recommended to determine the condition by increasing the temperature of the high temperature test by 15; whether the photochemical reaction of materials and components should be evaluated. For more information, see IFC 60741 1 C, 9) Recommended test conditions. CB/T 47!8.1 provides thermal radiation values, and its effects are usually included in high temperature tests: Products installed near high heat radiation sources may require special anti-radiation measures such as heat shields, insulation layers, or require additional high temperature tests. The degree of temperature rise is the "cooling level" of the heat source. There is no push-out test. There is no extended line B: T 2425 Test, this condition is sufficient for most products. If special conditions (123 or 121) are selected, the most protective measures should be taken, especially for large products. If the evaluation is delayed, the user must develop his own evaluation method. 1) The selection of the recommended severity level is to show the influence of some non-type storage locations, see Note 13) 12) There is no recommended storage test. There is no precipitation number in F/T278.1. When selecting materials, the influence of ice and snow should be considered. Design for this level is applicable See Note 13) 13) If there is no suitable data, the user is encouraged to select from 25125177 - one of the following: However, from (B/12423.38) select the appropriate test, duration and test severity level, as a guide + the following can help users select the appropriate test:) Dripping: If the product is usually rainproof - but there is no leakage such as condensation or dripping water, then 8
