BS ISO 20087:2016 pdf download.Photography — Digital still cameras — Battery life measurement
1 Scope
This International Standard specifies measurement method of battery life for consumer-use digital still cameras (hereinafter referred to as “DSC”).
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1 number of shots
number of pictures shot by a digital camera under the conditions stipulated in the measurement procedure in this International Standard
3 Measurement method
3.1 General
a) All the still-photography functions shall be utilized to their full extent when the measurement is conducted. The functions which have nothing to do with taking still photography (e.g. audio- recording and movie-recording functions) need not be activated during the measurement.
b) The camera’s function-setting parameters, except those defined in this International Standard, shall be identical to factory shipping settings. If the measurement is conducted with parameters that are different from the factory shipping settings, such settings parameters shall be reported along with the measurement results. If certain setting parameters are not defined by the factory shipping settings (see Annex B), the measurement shall be conducted using the settings which are most likely employed by the users of the applicable cameras, and information which can identify such setting parameters shall be reported along with the measurement data.
c) Some of the functions whose test conditions are defined in this International Standard may be ignored if a camera to be measured is not equipped with those functions.
d) If the power level is not fully determined by the factory shipping setting, the measurement shall be made with the operation that result in the highest power demand level for the camera.
Summarized priorities for the above a), b) and c) are as follows.
— The measurement conditions of the standard procedure which are listed in 3.2 to 3.8.
— Function-setting parameters which are not listed in 3.2 to 3.8 shall be identical to the factory shipping settings.
— If any parameters cannot be defined by the factory shipping settings, such parameters shall be set to ones which are assumed to be most likely employed by the users of the applicable cameras.
3.2 Battery
a) Battery type is not specified for the measurement, but information that can identify the battery shall be reported along with the measurement results.
b) When using a primary battery, a new battery shall be used. When using a secondary battery (rechargeable battery), the battery shall be fully charged (see Annex B).
3.3 Recording media
Not specified, but information that can identify the recording media shall be reported along with the measurement results.
