3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 15947-1:20 15 apply.
4 Test environment
4.1 General
The test area shall be a clean, flat, horizontal, non-flammable and sound reflecting surface (for example concrete). The test sample shall be placed in accordance with the instructions on the label in the centre of the test area.
4.2 Indoor
The test area shall be indoors.
The test area shall be inside a fume cupboard, or similar encEoseci space, which is capable or preventing movement of air.
4.3 Outdoor
4.3.1 General
The test area shall be an outdoor site. If applicable, provisions shall be made at the centre of the test area for partially burying into the ground.
If applicable, insert support pole in the centre of the test area.
A means of measuring the wind speed at a height of 1,5 m above the ground shall be provided. No performance testing shall be carried out if the wind speed exceeds 5,0 rn/s.
4.3.2 Category Fl
A test area meeting the requirements given in 4.1, with a radius of at least 2,0 m and a circle, radius 1,0 m, shall be marked around the centre of the test area.
4.3.3 Category F2
A test area meeting the requirements given in 4.1, with a radius of at least 9,0 m and a circle, radius 8,0 m, shall be marked around the centre of the test area.
4.3.4 Category F3
A test area meeting the requirements given in 4.1. with a radius of at least 16,0 m and a circle, radius 15.0 m, shall be marked around the centre of the test area.
4.4 Monitoring height
Two positions for monitoring the height of ascent and angle of Ilight shall be provided, at a measured distance of at least 50 m from and at an angle of 900 to each other in relation to the testing point. If the monitoring positions are not in the same horizontal plane, appropriate corrections shall be made in the calculation of heights.
If necessary the measuring distance and the number of positions may be adapted to the fIrework.BS EN 15947-4 pdf download.
