This part identical with ISO 2875:2000 "Packaging intact, filled transport packages and unit loads spray test." GB/T 4857.9-1992 "Transport packages spray test" in this section instead.

Section compared with the GB/T 4857.9-1992 The main changes are as follows.

--- In the scope of the original will only apply to the transport package modified to apply to transport packages and unit loads;

--- Adds a chapter terms and definitions, to increase the "test sample" term;

--- Chapter 4 Test principle increases the continuous and intermittent spraying;

--- 5.2 adds methods A and B;

--- Canceled 6.1 to 6.3 (1992 edition);

--- Increased in Chapter 6;

--- Increased 5.3 sprinkler system;

--- Increased 5.4 sprinklers schematic in Figure 1;

--- To modify Chapter 5 (1992 edition) was 7.1 (this version);

--- Modify the contents of the test report.

1 Scope

GB/T 4857 provisions of this part of the time used to transport packages and unit cargo spray test test equipment main performance Requirements, test procedures and test the contents of the report. Pretreatment methods can also be used to package other tests performed before the study due to water washout and Resulting in reduced strength of the package case.

This section applies to assess transport packages and unit loads of anti-dumping rain on the performance and packaging contents protection. It can as a single test, it can be used as part of the series of tests.

3 Terms and Definitions

The following terms and definitions apply GB/T 4857 of this section.

Complete, filled transport packages and unit loads.

4 Test principle

The test sample is placed in the ground test site, at a certain temperature water at a predetermined time and rate of the test sample surface spray.

Spray method is divided into continuous (Method A) and (Method B) batch.
