The following results have been determined for test substance.

Pmax = 7.4 bar @ 500 & 1500 g.m-3

(dP/dt)max = 638 bar.s-1 @ 2000 g.m-3

Kst value = 173 bar.m.s-1

St class = 1

Ambient Temperature = 19

Conclusions:
The Maximum explosion pressure Pmax was determined to be 7.4 bar g, Kst value was determined to be 173 bar.m.s-1 and classified as St class 1.
Executive summary:

The test is conducted to determine the explosion severity (maximum pressure (Pmax) and rate of pressure rise (dP/dtmax)) of a dust cloud under specified test conditions according to BS EN 14034 parts 1 & 2.

The 20 L Sphere Test gave a Pmax of 7.4 bar and a Kst value of 173 bar.m.s-1 therefore the sample falls within the St 1 classification or low explosion severity potential.
