47、ission. They have widely been used for decades in the chemical and oil industry, and a variety of national standards is available. This International Standard was prepared by an international group of experts, whose aim was to establish an international basis by harmonizing and incorporating recent
48、national developments and standards as far as reasonable.This International Standard addresses manufacturers (performance requirements) and test institutes (test methods), as well as customers (limits for use).Only relatively general performance requirements are specified and these are kept to a str
49、ict minimum. Experience has shown that excessively specific requirements in this field often create unjustified restrictions and prevent innovative solutions.The hazard identification of common applications found in industry leads to the specification of the test methods. These test methods reflect standard practical situations and, as such, form the heart of this International Standard because they also allow classification of the various types of flame arresters and then determination of the limits of use.A considerable number of
