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.
