Non-destructive testing. Characteristics of focal spots in industrial X-ray systems for use in non-destructive testing - Edge method1 Scope This European Standard specifies the checking of focal spot dimensions above 0,5 mm of X ray systems up to and including 500 kV tube voltage, by means of radiographs of sharp edges. The image quality and the resolution of X ray images depend highly on the characteristics of the focal spot. The imaging qualities of a focal spot are based on the two dimensional intensity distribution in the object plane. The edge method is especially useful for

only if this forms part of the overall preventive effectiveness of the product

Contents of BS EN 10028-7 contain:

◦ the frame structure on the individual communications channels at the physical interface between the CAU and the network as required for 'normal' 56 kbit/s or 64 kbit/s bearer services as opposed to aggregated bearer services

For these parts of SRP/CS

IEC Type designation

ensuring noise immunity and prevention of electrical interferences

These items shall be considered to comply with this standard if they comply with the property requirements listed in Table 1 with the exception of dimensions

Metric (A/F) 3

This document defines the classification methodology of time-constrained situations and their requirements

to control the reaction of materials to ignition sources of a variety of sizes

Hence BS EN 3385 walks you through the characteristics of axial mounting external retaining rings

but this standard is not exhaustive in the sense that product standards may well require testing according to test method standards which are not included in this standard
