This European Standard specifies requirements, tests and performance criteria for point-type heat-sensitive detectors that:
(a) have high response temperatures;
(b) contain at least one element having a static response threshold;
(c) have heat-sensitive elements (excluding elements having auxiliary functions, e.g. characteristic correctors) that are not doser than 15 mm to the mounting surface of the detector.
