Foreword
GB/T 22638 "aluminum foil test method" is divided into 10 parts.
- Part 1. Determination of thickness;
- Part 2. Detection of pinholes;
- Part 3. Detection of adhesion;
- Part 4. Determination of surface wetting tension;
- Part 5. Detection of wettability;
- Part 6. Determination of DC resistance;
- Part 7. Determination of heat seal strength;
- Part 8. Determination of texture content;
- Part 9. Hydrophilic testing;
Part 10. Determination of the surface density of the coating.
This part is part 1 of GB/T 22638.
This part is drafted in accordance with the rules given in GB/T 1.1-2009.
This part of the replacement GB/T 22638.1-2008 "aluminum foil test method Part 1. the thickness of the determination of weight method", and
GB/T 22638.1-2008 compared to the main technical changes are as follows.
--- the standard name changed to "aluminum foil test method Part 1. the thickness of the determination", delete the "weight method" three words;
- the scope of application of different methods is defined;
--- increase the normative reference documents;
--- increase the definition of surface density;
--- increase the density of 3102,8079 alloy, increasing the calculation of the surface density;
--- modified the requirements of the sampler, modified the area deviation;
--- eliminates square sampling and deviation;
--- increase the sampling pad paper requirements;
--- delete the measurement accuracy;
--- increase the vertical optical method and digital micrometer method.

Aluminum foil test method
Part 1. determination of thickness
1 Scope
This part of GB/T 22638 specifies the method for determining the thickness of aluminum foil.
The weight method specified in this section applies to the determination of non-composite foil thickness of thickness less than 0.10 mm.
The vertical optical method specified in this section applies to the determination of the thickness of the composite foil thickness less than 0.10 mm.
The digital micrometer method specified in this section shall apply to the determination of the thickness of aluminum foil with thickness not less than 0.10mm.
2 normative reference documents
The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article
Pieces. For undated references, the latest edition (including all modifications) applies to this document.

Representation and Judgment of Numerical Correction Rule and Limit Value of GB/T 8170
3 terms and definitions
GB/T 8005.1-2008 Definitions and the following terms and definitions apply to this document.
3.1
Surface density arealdensity
Quality of aluminum foil per unit area.
4 weight method
4.1 Principle of the method
This part calculates the thickness and surface density of the aluminum foil by weighing the mass of the aluminum foil with a known area and density.
4.2 Instruments and equipment
4.2.1 analysis of the balance, the sense of 0.1mg.
4.2.2 sampler, the sample area of 100cm2 quantitative standard sample sampler.
4.3 Determination
4.3.1 Remove the wrinkled part of the outer layer of aluminum foil roll, remove the sample from the foil, the sample with more than 100cm2 area of paper up and down clip
Live, the paper used shall not cause sample defects.
4.3.2 Sampling a sample with a sampler (4.2.2) on the aluminum foil, and the area deviation of the specimen shall not be greater than ± 0.35cm2.
4.3.3 Wipe the sample with absolute ethanol or other suitable solvent before testing to remove oil or dirt.
4.3.4 Place the surface clean and dry sample on the analytical balance (4.2.1) and weigh it to the fourth digit after the decimal point, and record the mass m.
