GB 28645.1-2012Safety code for inspection of dangerous goods -- Chemical oxygen generator (English PDF)

4.1 General Requirements Appearance

4.1.1 Design of chemical oxygen generator (hereinafter referred to as generator), rational manufacturing, testing equipment and to structure, good protective properties, can withstand

Risk under normal conditions of transport.

4.1.2 generators and materials to be loaded material may not occur any reaction affecting its strength.

Engraving and Printing, print or paste marks, logos and dangerous goods color label should be clear on the exact 4.1.3 generator, about in line with GB 19458

Requirements.

4.2 Performance Requirements

4.2.1 In the case where the packaging is not applicable, the generator should be able to withstand 1.8m height from the most vulnerable parts dropped onto a rigid, non-elastic

Of the test on a flat horizontal surface, neither leakage of contents, resulting in not start.

4.2.2 starter generator should have at least two possible to prevent accidental activation of the device effectively.

5.1 Test Equipment

Drop tester, in line with GB/T 4857.5 requirements.

5.2 Drop height

Drop height is 1.8m.

5.3 Test procedure

5.3.1 a first set of three specimens falling portion. The sample was oriented inclined rib portion at its highest point, the center of gravity line of gravity through the lower rib

At the impact of a plane perpendicular to the surface of the lowest point of striking impact. As none of the samples flange should strike a circumferential seam or edge.

5.3.2 a second set of three specimens falling portion. the first group to be dropped, there is no test to the weakest portion impinges on the impact surface,

The valve protection, sample solder (bonding) joints.

After the sample drop 5.3.3, observe the contents of the leaks, the generator is started.

7.1 generator-piece package should meet Class II packaging performance level.

7.2 The use of intermediate bulk containers or large packaging should be consistent with GB 19434 and GB 19432 requirements.

7.3 shipping package generator should have to meet the following conditions when a generator is started in a package.

a) Other generator does not start;

b) the material will not ignite;

c) temperature of the entire outer surface of the package does not exceed 100 °C.

8.1 Test items

Chapter 4 of this standard, the requirements of Chapter 5 one by one test.

8.2 Test conditions

When any of the following circumstances, should be carried out inspection of hazardous properties.

--- When the production of new products or old products converting;

--- After the official production, such as materials, processes are major changes that may affect product performance;

--- In normal production, every six months;

--- After the product long-term shutdown, resume production;

When --- factory inspection results with the results of the last test hazardous characteristics are quite different;

--- national quality supervision agencies to conduct inspection of hazardous properties.

8.3 determine the rules

8.3.1 Appearance

First, according to the standard general visual inspection, using decision rules GB/T 2828.1 health check a sampling program, the reception quality

Limit the amount of 4.0 (AQL = 4.0), acceptance number in Table 2.

Table 2 units member acceptance number

Normal single sampling AQL = 4.0

The number of samples to determine the number unqualified acceptance number

8.3.2 Drop

Performance testing in general appearance inspection on the basis of tests carried out in accordance with Chapter 5. Generator requires neither dropout content, also

It does not cause start.

8.4 substandard batch

If the test result is only a failure, you should double sampling re-examined, as there are for one or more failed, it is judged

The inspection lot failed.
