AS ISO 20087:2019 PDF
The objective of this Standard is to specify measurement method of battery life for consumer-use digital still cameras.
For digital cameras, long battery life is one of the important features. The Camera and Imaging Products Association (CIPA) defined a CIPA standard “Procedure for Measuring Digital Still Camera Battery Consumption” for specifying a standard measurement procedure. The procedure gives useful information on battery life to end-users for making a selection from a variety of digital cameras.
This International Standard is based on the CIPA standard mentioned above and it is referenced in the Bibliography. The standardized measurement procedure primarily includes high powerconsuming functions such as image display on picture monitor, use of flash, and zoom and retractable lens movement.
