2 Normative references
The following documents are essential for the application of this document. For dated references, only the dated version applies to this article
Pieces. For undated references, the latest version (including all amendments) applies to this document.

3 terms and definitions
The following terms and definitions apply to this document.
3.1
Sprinkler sprinkler
A device that sprinkles water in accordance with the designed sprinkler shape and volume.
Note. Due to the effect of heat, it starts automatically within a predetermined temperature range.
3.2
Response time coefficient responsetime index; RTI
A measure of the sprinkler's action sensitivity, the calculation formula is.
RTI = τu0.5
Where.
RTI --- response time coefficient, unit is (msec) 0.5 [(m · s) 0.5];
τ --- time constant of the thermal sensor, the unit is second (s);
u --- gas flow rate in meters per second (m/s).
3.3
Standard orientation
Position the airflow direction perpendicular to the sprinkler inlet axis and produce the shortest response time.
Note. When the heat-sensitive element is symmetrical, the standard orientation is the orientation that makes the airflow direction perpendicular to both the axis of the sprinkler water flow and the plane where the yoke arm is located;
When the heat-sensitive element is asymmetric, the standard orientation is to make the airflow direction perpendicular to both the axis of the sprinkler's water flow and the plane of its yoke arm.
The heat sensitive element is in an orientation upstream of the airflow.
3.4
Worst-case orientation
Orientation that makes the airflow direction perpendicular to the sprinkler inlet axis and produces the longest response time.
