ESD teste (High Voltage Test)

Milre’s digital door locks are designed to provide safe usage and protection against intentional electric shocks and high-voltage environments that may be associated with illegal intrusion attempts.

KS/KC Related Standards Milre’s Standards Remarks
The conditions in which static electricity of 8 kV is applied to the metal parts and 15 kV to the non-metal parts Compliance with KS standards
The conditions in which pulses of 25 kV are applied to the metal parts and 30 kV to the non-metal parts, continuously for 200 times (each pulse lasting 20 seconds) at a cycle of 10 Hz The conditions in which the digital door locks are subjected to 600 consecutive applications (for 1 minute) under the same conditions

The cold resistance, heat resistance, and moisture resistance tests

Given the exposure of digital door locks to external environments, it is essential to ensure their reliability and performance in different conditions. To meet the requirements of various environmental conditions, rigorous tests are conducted on the door locks, including high-temperature, high-humidity, low-temperature, and condensation tests.
