19、by Technical Committee CEN/TC 138, Non-destructive testing, the Secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2001, and conflicting national standards
20、 shall be withdrawn at the latest by July 2001. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This European Standard is considered to be a supporting standard to those application and product standards which
21、in themselves support an essential safety requirement of a New Approach Directive and which make normative reference to this European Standard. This standard about “Non destructive testing Acoustic emission Equipment characterization” consists of the following parts: Part 1: Equipment description Pa
22、rt 2: Verification of operating characteristics Part one of this standard gives a description of the main components of an AE monitoring system. Part two of this standard gives methods and acceptance criteria for verifying the electronic performance of an AE monitoring system. These methods and acce
23、ptance criteria are used to routinely check and verify the performance of an AE monitoring system composed of one or more channels during its life time. Annex A is informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are boun
24、d to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
