ISO 13850 Emergency Stop Functionality Testing in Robots
The ISO 13850 standard is a crucial document for ensuring the safety of robotic systems. This standard provides guidelines on how to test and verify that emergency stop functionality works as intended, which is essential for safeguarding human operators and bystanders from potential hazards associated with malfunctioning robots. In this section, we will delve into the intricacies of testing emergency stop functionality in accordance with ISO 13850.
The emergency stop function in robotic systems must be robust and reliable to prevent accidents. This involves verifying that when the emergency stop button is pressed, all axes of the robot are brought to a safe position within acceptable time limits. The test setup typically includes a robotic arm or manipulator with programmable controls. The specimen preparation involves calibrating the robot’s sensors and programming them to execute a predefined sequence of movements.
Testing protocols for ISO 13850 are stringent. They require that the emergency stop function is tested under various conditions, including different load scenarios, environmental factors like temperature variations, and power supply interruptions. The apparatus used in these tests includes high-precision sensors to measure the robot’s position and velocity accurately.
The acceptance criteria for this test ensure that the robot halts within a specified safe zone around the operator, typically defined by a radius of 1 meter or less. Additionally, the deceleration rate must not exceed predetermined thresholds to prevent sudden stops causing harm to personnel.
