Technical Terminologies

Controlled Closing Speed

This term refers to the regulated rate at which a door is closed. A door closer must be calibrated so that the closing speed does not result in abrupt movement or slamming, which could compromise safety and contribute to wear.

Over-Tripping Protection

A mechanism integrated within the door closer that prevents the door from closing too forcefully once it reaches the closed position. This feature minimizes undue stress on both the door and the closer, preserving operational integrity.

Dampening Efficiency

Defined as the capacity of the hydraulic system to absorb kinetic energy, thereby reducing noise and ensuring a smooth door closing action. High dampening efficiency is critical for reducing vibrations and preventing abrupt closure.

Adjustment Mechanisms

These are the configurable elements of a door closer that allow installers to fine-tune parameters such as closing force and damping response. Adjustment mechanisms are essential for adapting the device to specific door types and use cases.

Empirical Metrics

The standard prescribes specific numerical benchmarks for these definitions. For example:

• Closing Time: Typically expressed in seconds, with a range that is deemed acceptable for various door weights.
• Force Metrics: Quantified using calibrated instruments to ensure that the pressure exerted is within safe operational limits.
• Efficiency Percentages: Often given in terms of energy dissipation rates, ensuring that the door closer operates within predetermined parameters.
