Stable detonation flame arresters with nominal diameters from DN50 to DN300 were tested in accordance with the ISO 16852 standard, and the criteria for determining steady detonation were studied. According to the results of flame arrester tests, using the inner diameter of the pipeline as the basis for the pressure division yielded more accurate results, which was not clearly described in ISO 16852 standard. The target values of P md /P TB for the DN50 flame arrester were too small. Further studies are needed to determine appropriate ratios of P md /P TB for flame arresters with different pipe diameters. The run‐up distance required to form stable detonation was beyond L = 120 D, which is commonly believed to be the required distance for stable detonation to establish. Therefore, it is important to evaluate the conditions where flame arresters to be used and the conditions under which the flame arresters were tested.
