31、ments for the competence of testing and calibration laboratories (ISO/IEC 17025:1999. 3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in prEN 13857-1 apply. 4 Apparatus 4.1Means of initiating the shock tube, either an initiating device (percussion
32、cap, spark, etc.) or an initiating detonator provided that the shock tube and measuring equipment are protected against the fragments from the initiated detonator. 4.2System for monitoring and recording the propagation of the shock wave, equipped with two optical sensors (e.g. optical fibres, see A
33、and B in Figure 1) and capable of measuring the time taken for the shock wave to travel between the two sensors, to an accuracy of ? 1 s. 4.3Conditioning chamber, which can maintain a temperature of (20 ? 2) C. 5 Test pieces Select 20 lengths of shock tube, each at least 2,4 m long. If the shock tub
34、es are assembled with detonators, the lengths shall be taken from 20 detonators of the same specific type. If the detonators form part of a series with different delay times select detonators with delay times distributed as evenly as possible throughout the series 6 Procedure Cut the required length
35、s of shock tube and immediately seal the cut ends, e.g. by adhesive tape or other suitable means. Condition the sealed lengths for at least 2 h at (20 ? 2) C prior to testing. Install the two sensors in contact with the shock tube as in Figure 1. The distance between the sensors dAB shall be at leas
36、t 1 000 mm, measured to an accuracy of ? 5 mm. Remove the seal if necessary and initiate the shock tube.
