ISOISO 3452-3:1998(E) v Introduction At the present time, one part of this Standard is published independently on the Euro
16、pean and ISO levels, the others are under the Vienna Agreement and consequently have the ISO number at the European level. However, the Vienna agreement was applied during the work, so some European Standards have referenced them under their previous European number. The following table gives the co

19、ntrast penetrant product families; Type 2 reference blocks are used for routine assessment of the performance of both fluorescent and colour contrast penetrant facilities and part-used containers. The reference blocks are used in the same conditions as the pieces to be tested according to EN 571-1.
