Test methods for aluminum and aluminum alloy foils - Part 2. Determination of pinhole ICS 77.040.01 H20 National Standards of People's Republic of China Replacing GB/T 22638.2-2008 Aluminum foil test method Part 2. pinhole detection Part 2. Determination ofpinhole 2016-12-13 released 2017-11-01 implementation General Administration of Quality Supervision, Inspection and Quarantine of the People 's Republic of China China National Standardization Management Committee released ForewordGB/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. Detection of texture content; - Part 9. Hydrophilic testing; Part 10. Determination of the surface density of the coating. This part is part 2 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 22638.2-2008 "aluminum foil test method Part 2. pinhole detection." This part with GB/T 22638.2-2008 compared to the main technical changes are as follows. --- modified the English name of the pinhole in the standard name; --- modify the scope of the description; --- increase the normative reference documents; --- gives the definition of pinhole; --- modified the observation room and pinhole description, the detection area to modify the "appropriate area", provides its "should not less than 0.1m2"; --- frosted glass transmission light intensity modified to "1000lx ~ 1500lx", an increase of ambient light detection location requirements; --- modified the pinhole number detection process description, increased the pinhole diameter detection method; The recommended number of aluminum foil pinholes for power capacitors is recommended.
