7, --3 Technical basis and definitions established in this standard. 4 Requirements
4.1 Implementation and frequency of tests
4, 1.1 Before the device is put into use, its design model should be successfully tested. The design model of the device is the design, specification, name and material prototype registration and packaging method determined by the state. It can include various surface treatments. It also includes only the design model that is higher than the design model. 4.1. The production sample of the customer needs to be repeated twice according to the specified interval. 4.1.3 If the design and manufacturing method of the container change, the test may also be carried out for the goods. 4.1.2 If the inner container is different from the tested type in other aspects, such as the inner container is smaller or smaller, and the outer dimensions are smaller, the competent department may allow optional testing later. 4.1.5 If the inner container of the same type or similar in appearance cannot pass the "type test", then this type of inner container may also be packed in this other container: if the outer dimensions are different or smaller than the inner container, the same level of performance can be maintained. The following changes in the form of the inner container are allowed without the need for packaging and testing: a) If the inner container is similar or smaller in size, the inner container shall have a design similar to the tested inner container (shape, rectangle, etc.). The original test container has the same or smaller opening as the inner container;
CH19270.2—2003
The inner container has a similar or smaller opening, and the closure design is similar, such as a rotating mold, a friction lens, etc. ", and sufficient additional cushioning material is used to fill the gap to prevent the internal container from moving significantly: a. Leave the gap in the middle of the outer content and alternate with the tested packaging: b. If sufficient cushioning material is used to fill the gap to prevent the inner container from moving significantly, use less tested contents or the type of contents in a) mentioned in the test.
4.1.6 The inner container with any single number of objects or liquids is packed in an outer container. The following cases cannot be tested.
a: When there is a risk of the inner container being damaged (such as being full), the inner container should be filled according to the third method, and the skin containing the inner container should be delivered to the customer. 1) The total weight of each container shall not exceed the total weight of each container used in the drop test. 2) The thickness of the material between the outer and inner containers of each container shall not be less than the thickness of the container used in the original test. If only inner containers are used in the original test, the thickness of the padding between the inner containers shall not be less than the thickness of the outer and inner containers used in the original test. Use a smaller container (compared with the one used in the drop test). Sufficient padding material should be used to fill the gap. 3) The outer container should successfully pass the test of 5.4. The total weight of the same package shall be determined according to the total weight of the inner containers used in the drop test. 4) The liquid-filled contents shall be filled with absorbent material in an amount sufficient to absorb the liquid contained in the container. 5) The outer container shall be used with an anti-leakage outer container. If the inner container contains liquids, or the outer container does not leak, it should be equipped with any indication of what liquid or solid contents will be retained in the event of leakage, such as leak-proof liners, plastic bags or other equally effective containers for liquids. The absorbent material required by the requirements should be broken when leaving the liquid contents; (g) The container should be marked in accordance with Chapter 6 of G152731-200 to indicate that it has passed the Class 1 packaging performance test. The marked inner weight should be the sum of the outer weight plus half of the inner weight of the container after the test described in a). This package marking should also refer to the treatment described in Section 6.1.4 of G152731-200 (B: 270.1-200). 4.1.7 Some inner layers need to be treated or coated due to safety requirements to ensure that they still maintain their protective performance after the test. 4.1.9 The container shall be tested and labeled in accordance with the provisions applicable to the type of container or containers to be used for transporting the goods or contents, except in the following circumstances: a) the composition of the test substance used in the test shall not be less than the original amount. Additives, such as bags, may be used to achieve the required total packaging quantity, provided that they do not affect the test results. Alternatively, when performing the test, the drop rate may be changed in accordance with 5.1.b): h) the container shall have successfully withstood the 501a atmospheric pressure test frequency and the results of the test shall be reflected in the test report required by 5.7: c) the rate shall be marked with the word "\" as specified in Article 5.1.1 of GB 19271.1:2005. .1.15 The airtightness test of the device shall be successfully passed under the following conditions and shall be able to reach the appropriate test level in Table 3.2.4: a) before the first operation; b) after failure or repair and before the next operation. The test station shall not be affected by the abnormality of the internal device of the container and the external device shall be used for the test. 4.2 Test of the device 4.2.1 For the difficult-to-use piercing devices, including the combination of the piercing devices used in the surrounding, the virtual reduction test shall be carried out. For the piercing devices or single piercing devices or the surrounding piercing devices used in the combination of the ... 19270.2—2003
The substance or material of the container can be replaced by other substances or products, unless this group of assumptions will invalidate the test results. For solid containers, when a substance is used instead, the substance must have the same physical characteristics (points, size, etc.) as the substance to be transported. Supplementary materials, such as granules, can be used to transport the required total weight of the package, as long as their effective position does not affect the test results. 4.2.2 When the container containing liquid is subjected to the drop test, if other substances are used instead, the substance must have a relative density and viscosity similar to the substance to be transported. Water can also be used to carry out the liquid test under 5.1.5. 4.2.3 Paper and fiberboard containers should be placed in a controlled temperature and relative humidity environment for at least 24 hours. There are three methods below, and one should be selected: temperature (23 ± 2) and relative humidity (+2). The other two methods are: temperature: 202) and relative humidity (+2% or temperature (2712) and relative humidity (±): the average value should be within these limits. Otherwise, the technical and product changes may cause individual relative humidity to vary. Regardless of the test results, the average value should be within these limits.
4.2.4 Natural wooden energy-saving barrels should be filled with water for at least 4 hours before testing. 4.2.5 When using plastic containers, plastic composite containers and containers with layers of chain for the first time, Before the test, the dangerous goods to be transported must be stored for more than 6 hours for compatibility testing. For the first and last 24 hours of the storage period, the test sample should be placed in a ventilated air container with a closed device. The time for each time is 5 minutes. After the storage period, the product should be subjected to the appropriate tests listed in 32.3.3 and 5.4. If the material contained in the packaging may cause the plastic to produce mechanical cracking, the degree of stress reduction should be reduced by one sample of the substance or a different substance with at least the same degree of stress opening effect on the plastic. This weight should be the same as the amount that may be piled on the product during transportation. The total cover of the package & parts, including the test sample, is 3m high.
