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.

This document describes the scientific background and rationale for the content of EN 17950, Protective helmets - Test methods - Shock absorption including measuring rotational kinematics.

This document specifies basic requirements for gearboxes to operate industrial valves for manual and automated on/off and modulating duties, including manual override gearboxes. It includes guidelines for classification, design and methods for conformity assessment. This document does not cover gear systems which are an integral part in the design of valves and subsea gearboxes. Other requirements or conditions of use different from those indicated in this document are agreed between the purchaser and the manufacturer or supplier (first party) prior to order.

The amendment to EN IEC 60601-2-57 contains the Annexes ZA (Normative references to international publications with their corresponding European publications) and ZZ (Relationship between this European standard and the General Safety and Performance Requirements of Regulation (EU) 2017/745 aimed to be covered).
These two Annexes are necessary for the harmonization of the standard to the Regulation (EU) 2017/745.

This document provides the guidelines of CEN and CENELEC’s policy towards building partnerships with European organizations, associations and other recognized stakeholders who have an interest in European standardization and are willing and able to provide added-value knowledge and to actively contribute with inputs and proposals to CEN and/or CENELEC corporate and technical bodies.

This document specifies a method using automated Randall extraction for the determination of the hexane extract (or light petroleum extract), called the “oil content”, of oilseeds used as industrial raw materials. The procedure for sunflower seed is different from those for others seeds as it includes an additional moisture content determination after the seed has been ground to prepare the test sample. If required, the pure seeds and the impurities can be analysed separately. In the case of groundnuts, the pure seeds, the total fines, the non-oleaginous impurities and the oleaginous impurities can be analysed separately.

This document specifies the quality, safety requirements and test methods for Euodia fruit. It is applicable to Euodia fruit that is sold and used as natural medicines in international trade, including Chinese materia medica (whole medicinal materials) and decoction pieces.

c)   free of defects.
1.4   This document is not applicable to lifting appliances manufactured before the date of its publication.

This document specifies the quality and safety requirements for Anemarrhena asphodeloides rhizome. This document applies to Anemarrhena asphodeloides rhizome that is sold and used as natural medicines in international trade, including Chinese materia medica (whole medicinal materials) and decoction pieces derived from the plant.

This document specifies the requirements for the attachment of multi-turn actuators to valves. Throughout this document, “actuator” can be understood as “actuator” or “combination of actuator with gearbox” providing a multi-turn or linear output. This document specifies: flange dimensions necessary for the attachment of actuators to industrial valves [see Figure 1 a)] or to intermediate supports [see Figure 1 b)]; those driving component dimensions of actuators which are necessary to attach them to the driven components; reference values for torque and thrust for flanges having the dimensions specified in this document.

The European Commission will in its project "VAT in the digital age" (ViDA) mandate that VAT reporting on intra-EU transactions is performed in near real-time and based on EN 16931-1. This Technical Report defines the impact of this legislation on the various deliverables of CEN/TC 434, with a focus on the subset to be sent to tax authorities and how EN 16931-1 needs to be changed. The ViDA package applies to all EU member states and specific territories where the VAT legislation applies (e.g. Northern Ireland in respect to goods).
This document does not define the content of the common electronic message based on the electronic invoice to be sent to the authorities. The definition of that common electronic message (DRR message) is a task of the European Commission, possibly with help of CEN. As the DRR message is not an invoice, but a VAT report, it is not to be regarded as a Core Invoice Usage Specification (CIUS). The DRR message therefore needs not to obey the rules for developing a CIUS. For example, not all mandatory elements in the invoice need to be part of the DRR message.

This document gives guidance on planning, evaluating the risks, and conducting activities and techniques remotely for internal or external verification/validation (i.e. first, second and third party) of greenhouse gas (GHG) statements. It is applicable to cases where a verifier determines that the circumstances defined in ISO 14064-3:2019, 6.1.4.2, do not require an in-person site or facility visit or a validator determines that an evidence-gathering plan can include activities and techniques performed remotely as defined in ISO 14064-3:2019, 7.1.6. Activities and techniques applied remotely can be used by a verifier for activities such as inquiry of persons and documents, analytical testing, recalculation, estimate testing, cross-checking and reconciliation when a verifier’s risk assessment does not require the use of on-site activities and techniques. Activities and techniques applied remotely can be used by a validator when their use does not compromise the validator’s ability to assess whether the characteristics of GHG activities (see ISO 14064-3:2019, Clause 7) will meet the needs of intended users. This document is applicable to verifications/validations that use: a combination of activities and techniques applied remotely and on-site; exclusively activities and techniques applied remotely. NOTE Legislation can differ from jurisdiction to jurisdiction. It is the user’s responsibility to determine how applicable legal requirements relate to this document.

This document specifies requirements for the attachment of part-turn actuators, with or without gearboxes, to industrial valves. The attachment of part-turn actuators to control valves in accordance with the requirements of this document is subject to an agreement between the supplier and the purchaser. This document specifies: flange dimensions necessary for the attachment of part-turn actuators to industrial valves [see Figures 1 a) and 1 c)] or to intermediate supports [see Figures 1 b) and 1 d)]; driving component dimensions of part-turn actuators necessary to attach them to the driven components; reference values for torques for interfaces and for couplings having the dimensions specified in this document. The attachment of the intermediate support to the valve is beyond the scope of this document.
