This European standard specifies a method for the measurement of effective focal spot dimensions above 0,1 µm of X-ray systems by means of the edge method applied to digital images taken from hole type or disk type gauges. The imaging quality and the resolution of X-ray images depend highly on the characteristics of the effective focal spot, in particular the size and the two-dimensional…

This document specifies a method for the measurement of focal spot dimensions within the range of 5 µm to 300 µm of X-ray systems up to and including 225 kV tube voltage. This determination is based on the evaluation of an image with a dedicated focal spot that has been radiographically recorded using an edge and evaluated with a digital method. The imaging quality and the resolution of X-ray…

The JT file format specification for 3D visualization specifies the sequential order of bytes that comprise the segments of data required to represent an ISO 14306 file. The JT format is uniquely compressed to minimize file size. The JT file format specification for 3D visualization includes data descriptions that can represent the following data. — facet information (triangles), stored with…

ISO 17078-2:2007 provides requirements for subsurface flow-control devices used in side-pocket mandrels (hereafter called flow-control devices) intended for use in the worldwide petroleum and natural gas industry. This includes requirements for specifying, selecting, designing, manufacturing, quality-control, testing and preparation for shipping of flow-control devices. Additionally, it includes…

Statistical process control (SPC) concerns the use of statistical techniques and statistical or stochastic control algorithms to achieve one or more of the following objectives: a)      to increase knowledge about a process; b)     to steer a process to behave in the desired way; c)      to reduce variation of final-product parameters, or in other ways to improve performance of a process. These…

ISO 14044 requires the goal and scope of an LCA to be clearly defined and be consistent with the intended application. Due to the iterative nature of LCA, it is possible that the LCA scope needs to be refined during the study. This document specifies methodologies that can be applied to determine the carbon footprint of a product (CFP) or partial CFP of a hydrogen product in line with ISO 14067.…

Scope of the proposed deliverable This document focuses on recommended condition monitoring techniques for detecting and diagnosing developing machine faults associated with the most common potential failure modes for reciprocating compressors. It is intended to improve the reliability of implementing an effective condition monitoring approach for the compressors. It is also intended to help…

ISO 13348:2007 specifies performance tolerances and the technical data presentation of industrial fans of all types. It does not apply for fans designed solely for low-volume air circulation, such as those used for household or similar purposes (ceiling and table fans, extractor fans, etc.). ISO 13348:2007 covers the four installation categories defined in ISO 5801: A, free inlet, free outlet; B…
