Foreword
This Standard was drafted in accordance with the rules in GB/T 1.1-2009.
This Standard serves as a replacement of GB/T 16266-2008 Test Method of Packaging
Materials - Contact Corrosion.
In comparison with GB/T 16266-2008, except from editorial modifications, the main
technical changes are as follows:
---Terms and definitions are deleted (see Chapter 3 in Version 2008);
---The requirements for test environment conditions are added (see Chapter 3);
---The requirements for desiccator’s dimensions are modified (see 5.2; 4.2 in
Version 2008);
---The requirements for test specimen pretreatment are deleted (see 5.2.4 in
Version 2008);
---The operational requirements for rigid or block materials are modified (see 6.2
and 7.3.2; 5.2.2, 5.2.3 and 6.1 in Version 2008);
---The description of sampling quantity of granular materials is added (see 6.3;
5.2.3 in Version 2008);
---The requirements for test piece cleaning medium and storage time are modified
(see 7.1; 5.1 in Version 2008);
---The preheating temperature of test pieces is modified (see 7.4; 6.4 in Version
2008);
---Appendix A Result Evaluation is added (see Appendix A).
This Standard was proposed by and shall be under the jurisdiction of National
Technical Committee 49 on Packaging of Standardization Administration of China
(SAC/TC 49).

Test Method of Packaging Materials -
Contact Corrosion
1 Scope
This Standard stipulates contact corrosion test method of packaging materials against
the contacted metallic surface. It includes test environment conditions, reagents, test
materials, instruments and equipment, samples, test procedures and test report.
This Standard is applicable to contact corrosion test of packaging materials against
steel and aluminum. The contact corrosion test against the surface of other metallic
materials may take this as a reference.
2 Normative References
The following documents are indispensable to the application of this document. In
terms of references with a specified date, only versions with a specified date are
applicable to this document. In terms of references without a specified date, the latest
version (including all the modifications) is applicable to this document.

GB/T 15723 Laboratory Glassware - Desiccator;
GB/T 30435 Electric Gravity Convection and Forced Ventilation Ovens;
SH 0004 Solvent Oil for Use in Rubber Industry
3 Test Environment Conditions
Tests shall be conducted at 20 °C ~ 30 °C, and with the relative humidity of not more
than 80%.
5 Instruments and Equipment
5.1 Electric Blast Drying Oven
Electric blast drying oven shall comply with the requirements in GB/T 30435.
5.2 Desiccator
Desiccator shall comply with the requirements in GB/T 15723. The internal diameter
of desiccator body: 240 mm.
5.3 Electric Blower
Electric blower shall support two purposes---for cold and hot.
6 Samples
6.1 Flexible Sheet Material
Take representative test specimens from different parts of a sample. The dimensions
of each test specimen shall be: 75 mm 50 mm.
NOTE: flexible sheet material refers to flexible flaky material, for example, sheet of paper,
or, thin film.
6.2 Rigid or Block Material
Take representative test specimens from the flat surface of a sample. The dimensions
of each test specimen shall be: 75 mm 50 mm; the thickness shall not exceed 10
mm.
If the sample is smaller than the dimensions of the test specimens, then, multiple
samples shall be used.
NOTE: rigid material refers to material that is not easily deformed, for example, paperboard,
or, timber; block material refers to stereo-structured non-flaky material, for
example, foam block, or, rubber block.
6.3 Granular Material
Select a sufficient quantity of representative samples. Grind them into granules, till they
can pass through 40-mesh standard sieve but cannot pass through 80-mesh standard
sieve. Each piece of sample shall be able to cover an area of 50 mm 25 mm; within
the area of coverage, no metal test piece shall be exposed.
In terms of materials that are not suitable for grinding, each piece of sample shall be
able to cover an area of 50 mm 25 mm.
Record the test surface, including the part covered by glass slide and the part
uncovered by glass slide; whether the uncovered part generates rusty spots, corrosion
spots, and forms loosened or granular spots, and discoloration. In addition, describe
the quantity, the status, the distribution, and other test phenomena.
If necessary, take Appendix A as a reference to evaluate the result of steel test piece
and aluminum alloy test piece.
8 Test Report
Test report shall at least include the following content:
a) Test objective;
b) Serial No. of this Standard;
c) Detailed description of test pieces and samples used in test, including the variety,
dimensions, quantity and status, etc.
