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 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 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.

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 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 establishes basic principles and specifies requirements and methods to determine the cardinal values of bacteria and yeast strains and use them to predict microbial growth. The four main steps of the approach are: determination of the cardinal values in culture medium; determination of the correction factor in the target food; validation of the model; simulations. Four environmental factors are considered: temperature, pH, aw and inhibitors (e.g. organic acids). NOTE 1 Microbial competition is not considered as an inhibitor in this document and can be addressed by proper modelling approaches. The determination of cardinal values is performed in a two-step approach: the determination of maximum specific growth rates of the studied strain grown in broth under a defined range of values of the studied environmental factor(s); the use of recognized predictive microbiology secondary models to fit the obtained experimental data to obtain the cardinal values. The use of cardinal values in microbial growth simulation is based on predictive microbiology primary and secondary models. The cardinal values are combined with challenge test data to consider the matrix effect. Depending on the goal of the growth simulation, it is important to account for variation of cardinal values between strains within a bacterial or yeast species. Cardinal values are a good indicator of a strain growth ability for the studied environmental factors. They are therefore used as criteria to select strains, in addition to their origin and virulence, when performing growth challenge tests (see ISO 20976-1) or in methods validation (see ISO 16140 series). NOTE 2 This document focuses on the determination of cardinal values for one strain. The same methodology can be used to characterize multiple strains independently to cover biological strain variability and include these results in the predictions.
