GB/T 32485-2016Methods of evaluation of the battery life of a battery-powered watch (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the translation method equivalent to ISO 12819.:2009 "battery-driven watch battery life assessment method." and the normative reference in this standard international documents are consistent with the relationship between China's documents are as follows.

1 Scope

This standard specifies two methods for determining the battery life of a battery-driven watch and specifies that the manufacturer and the vendor inform the customer of the the labeling method.

According to the available information, both the theoretical battery life and the actual battery life are calculated using the formula given in this standard.

3 Terms and definitions

ISO 6426-2 and the following terms and definitions apply to this document.

Battery life the duration of the battery-driven watch is determined by the characteristics of the battery and the movement.

Note. watch battery life from the battery into the watch and began to drive the watch when the movement began, until the voltage dropped to the required level of movement of the watch and the watch stopped.

Actual battery life practicalbatterylife AP the battery life calculated after the self-discharge current of the battery during storage and transportation is considered.

Theoretical battery life theoretical batterylife AT Assuming that the battery is an ideal battery with no self-discharge current, calculate the battery life.
