This document specifies a method for the measurement of focal spot sizes 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 images depend highly on the characteristics of the effective focal spot, in particular its size and the two-dimensional intensity distribution as seen from the detector plane.
For the characterization of commercial X-ray tube types (i.e. for advertising or trade), the nominal values of Annex A are preferred.
NOTE            The same procedure can be used at higher kilovoltages by agreement but the accuracy of the measurement can be poorer.

The objective of this document is to conduct a neutral salt spray test in accordance with ISO 9227. The test is a proven method for assessing the corrosion protection of coatings of components such as bolts. For this reason, two coating variants were chosen for conducting the tests on hexagon bolts with a size of M6 × 50. The bolts were examined at specified points in time and the time of occurrence of grey veil, white rust and red rust was documented. The corrosivity of the salt spray was determined by means of two methods and also documented in an evaluation form. These two methods are the assessment of the mass loss of an uncoated steel panel as specified in ISO 9227 as well as the determination of the time until appearance of red rust on hot-dip galvanized steel panels in accordance with ISO 4042 and ISO 10683. The processing steps are specified in detail in a manual that was provided to the test participants. If followed precisely, these instructions allow for a comparative analysis of the results from the individual labs and make it possible to determine the reproducibility of the salt spray test. Another objective is to compare the two methods used to determine the corrosivity of the salt spray in order to establish the suitability of these methods by comparing the corrosion assessment results obtained for the bolts. In addition, the normative operating parameters (temperature in the test cabinet, collection rate, pH and density or NaCl concentration of the solution collected) were documented for every inspection date in order to ascertain whether there is any correlation with the results of the corrosion assessment performed on the bolts.

This document is applicable to environmental matters for a digital service. It establishes requirements and recommendations applicable for requirements gathering, design, implementation, operations, maintenance and the end of life of digital services in order to minimise adverse environmental impacts during all stages of its life cycle. It also establishes a common language and understanding on this subject. This document focuses on reducing the environmental impacts of a digital service. It therefore does not address all aspects of digital service design. For example, it does not address other aspects such as performance, resilience, reliability, availability or development language choice (see other standards covering these topics, e.g. ISO/IEC 25010 and ISO/IEC 27001). This document does not include matters linked to other corporate social responsibility (CSR) topics, e.g. social, cultural, diversity, inclusion or exclusion. This document is applicable to all development methodologies (waterfall, agile, etc.).

This document specifies the requirements, performance criteria and testing procedures for control and indicating equipment (CIE) intended for use in intrusion and hold-up alarm systems (I&HAS) installed in buildings. This document also applies to CIE to be used in IAS or HAS. The CIE can incorporate processing functions of other I&HAS components or its processing requirements can be distributed among such components. This document specifies the requirements for CIE installed in buildings using specific or non-specific wired interconnections or wire-free interconnections. These requirements also apply to basic DCC which can be installed outside of the supervised premises and mounted in indoor or outdoor environments. Where CIE shares means of detection, interconnection, control, communication, processing and/or power supplies with other applications, these requirements apply to I&HAS functions only. This document specifies performance requirements for CIE at each of the four security grades identified in EN 50131-1. Requirements are also specified for four environmental classes covering applications for indoor and outdoor locations. This document includes mandatory functions for all CIE for the appropriate security grade, as well as optional functions that can additionally be provided. This document does not cover requirements for compliance with EU regulatory Directives, such as the EMC Directive, Low Voltage Directive, etc. except in that it specifies the equipment operating conditions for EMC susceptibility testing as required by EN 50130-4. NOTE 1 In this document reference to the term "I&HAS" is used throughout, except where there is specific need to differentiate between the IAS and HAS portions of a system. The term is intended to include IAS and HAS when such systems are installed separately. NOTE 2 For products which integrate functions from, and which the manufacturer is claiming compliance to, several EN 50131 standards, the requirements of this document apply as well as any additional requirements from other relevant EN 50131 standards (e.g. a CIE with integral Warning Device is expected to meet the requirements of EN 50131-3 and EN 50131-4).

This document specifies requirements for two types, seven classes and three grades of wire- or textile-reinforced dredging hoses with nominal sizes ranging from 100 to 1 300. Such hoses are suitable for the delivery or suction of seawater or freshwater mixed with silt, sand, coral and small stones with a specific gravity in the range from 1,0 to 2,3 at ambient temperature ranging from -10 °C to +40 °C or for low-temperature hoses (designated -LT) ranging from -20 °C to +40 °C. This document covers two types of hose, as follows: type 1: floating type, for delivery only, which includes flotation material to give the hose buoyancy; type 2: submarine type for delivery and suction.

This document provides human-machine interface (HMI) design specifications in case an HMI is needed to secure the safe and/or fully understood execution of over the air (OTA) software updates for passenger cars (including sport utility vehicles and light trucks) and commercial vehicles (including heavy trucks and buses). The vehicle operator benefits from knowing if an OTA update has been successful or not, if an OTA update will influence the operation of the vehicle, or if the OTA update influences the quality of a feature. HMI specifications for the OTA software update provide support in case an HMI is needed in normal conditions, emergencies, low battery, avoidance of inadvertent actuations, alerts or specific non-standard situations.
