(1) EN 1992-4 provides a design method for fastenings (connection of structural elements and non-structural elements to structural components), which are used to transmit actions to the concrete. NOTE 1 Additional rules for the transmission of the fastener loads within the concrete member to its supports are given in EN 1992 1 1:2004, 2.7 and Annex A of this EN. NOTE 2 Inserts embedded in precast concrete elements during production, under Factory Production Control (FPC) conditions and with the due reinforcement, intended for use only during transient situations for lifting and handling, are covered by CEN/TR 15728. (2) EN 1992-4 is intended for safety related applications in which the failure of fastenings can result in collapse or partial collapse of the structure, cause risk to human life or lead to significant economic loss. (3) The support of the fixture can be either statically determinate or statically indeterminate. Each support can consist of one fastener or a group of fasteners. (4) EN 1992-4 is valid for applications which fall within the scope of the EN 1992 series. In applications where special considerations apply, e.g. nuclear power plants or civil defence structures, modifications can be necessary. (5) EN 1992-4 does not cover the design of the fixture. NOTE Rules for the design of the fixture are given in the appropriate standards meeting the requirements on the fixture as given in EN 1992-4. [Figure 1.1 - Fastener design theory - Example] (4) This document applies to single fasteners and groups of fasteners. In a group of fasteners, the loads are applied to the individual fasteners of the group by means of a common fixture. In a group of fasteners, this document applies only if fasteners of the same type and size are used. (5) The configurations of fastenings with cast-in place headed fasteners and post-installed fasteners covered by this document are shown in Figure 1.2. (6) For anchor channels, the number of anchors is not limited. [Figure 1.2 - Configuration of fastenings with headed and post-installed fasteners covered by this document] (7) This document applies to fasteners with a minimum diameter or a minimum thread size of 6 mm (M6) or a corresponding cross section. In case of fasteners for fastening statically indeterminate redundant non-structural systems as addressed in 7.3, the minimum thread size is 5 mm (M5). The maximum diameter of the fastener is not limited for tension loading but is limited to 60 mm for shear loading. (8) EN 1992 4 applies to fasteners with embedment depth hef ≥ 40 mm. Only for fastening statically indeterminate redundant non-structural systems as addressed in 7.3 smaller effective embedment depth may be used. For fastenings with post-installed bonded fasteners, only fasteners with an embedment depth hef ≤ 20d are covered. The actual value for a particular fastener can be found in the relevant European Technical Product Specification. (9) This document covers metal fasteners made of either carbon steel (EN ISO 898 1 and EN ISO 898 2, EN 10025 1, EN 10080), stainless steel (EN 10088 2 and EN 10088 3, EN ISO 3506 1 and EN ISO 3506 2) or malleable cast iron (ISO 5922). The surface of the steel can be coated or uncoated. This document is valid for fasteners with a nominal steel tensile strength f_"uk" ≤1 000 "N/" 〖"mm" 〗^"2" . This limit does not apply to concrete screws. (10) Loading on the fastenings covered by this document can be static, quasi-static and fatigue. The suitability of the fastener to resist fatigue is specifically stated in the relevant European Technical Product Specification. Anchor channels subjected to fatigue loading or seismic loading are not covered by this document. (11) The loading on the fastener resulting from the actions on the fixture (e.g. tension, shear, bending or torsion moments or any combination thereof) will generally be axial tension and/or shear.

This document specifies safety requirements and their verification for the design and construction of firewood processors, designed to be used for making firewood. Firewood processors are combined machinery that cut and then split the wood. This document covers machines where the cutting is done either by a chain blade or a circular saw, and splitting movement is done horizontally or near horizontally by one or more splitting wedges. If cutting or splitting is done by other means, e.g. by guillotine blade or vertical movement splitting, this document is not applicable. This document is not applicable for machinery, where the wood is required to be moved from cutting to the splitting by manual handing by the operator. This document deals with firewood processors that are designed in a way that only one operator carries out the work process, but it is foreseeable that other operators, e.g. for loading or unloading, will work on or close to the machine. This document deals with all significant hazards, hazardous situations and hazardous events relevant to these machines, when they are used as intended and under the conditions foreseen by the manufacturer. See Clause 4 for the list of significant hazards. This document is not applicable to machines which were manufactured before the date of its publication. This document is applicable for manually operated, semi-automatic and automatic firewood processors. This document is applicable to the following possible integral features of the firewood processor: - Integral outfeed conveyors - Integral infeed conveyors - Integral hold to run operated log lifting device Other accessories or added features of firewood processors are not covered by this document. These could be e.g.: - Separate conveyors or tables that are not integral parts of the machine - Other wood lifting equipment (e.g. winch or crane) - Other separate accessories of the machine, e.g. for cleaning the wood or packing the wood.

This document describes an analytical method for the determination of uranium in samples from pure product materials such as U metal, UO2, UO3, uranyl nitrate hexahydrate, uranium hexafluoride and U3O8 from the nuclear fuel cycle. This procedure is sufficiently accurate and precise to be used for nuclear materials accountability. This method can be used directly for the analysis of most uranium and uranium oxide nuclear reactor fuels, either irradiated or un-irradiated, and of uranium nitrate product solutions. Fission products equivalent to up to 10 % burn-up of heavy atoms do not interfere, and other elements which could cause interference are not normally present in sufficient quantity to affect the result significantly. The method recommends that an aliquot of sample is weighed and that a mass titration is used, in order to obtain improved precision and accuracy. This does not preclude the use of alternative techniques which could give equivalent performance. The use of automatic device(s) in the performance of some critical steps of the method has some advantages, mainly in the case of routine analysis.

This document specifies an analytical method for determining the neptunium concentration by spectrophotometry, with spectrophotometer implemented in hot cell or glove box allowing the analysis of high activity solutions, with a standard uncertainty, with coverage factor k = 1 of about 5 %, in nitric acid solutions after the dissolution of nuclear reactor irradiated fuels, at different steps of the process in a nuclear fuel reprocessing plant or in other nuclear facilities. The method is applicable to sample from the process containing a concentration of neptunium between 10 mg·l-1 and 400 mg·l-1 and uranium concentrations of up to 300 g·l-1.

This document specifies a method which applies to the preparation and validation of the standard materials generally called “large size spikes” with an uncertainty suitable for international nuclear safeguards used for measuring the content of plutonium and/or uranium by isotope dilution mass spectrometry. This measurement methodology can be applied to input solutions of irradiated Magnox and light water reactor fuels (boiling water reactor or pressurized water reactor); in final products at spent-fuel reprocessing plants; in feed and products of mixed oxide of plutonium and uranium (MOX); and in uranium fuel fabrication

This document applies to the testing of surfaces that may become contaminated by radioactive materials. The ease of decontamination is a property of a surface and an important criterion for selecting surface materials used in the nuclear industry, interim storage or disposal facilities from which contamination can be removed easily and rapidly without damaging the surface. The test described in this document is a rapid laboratory-based method to compare the ease of decontamination of different surface materials. The results from the test can be one parameter to take into account when selecting surface coatings such as varnish or impervious layers such as ceramics and other surfaces. The radionuclides used in this test are those commonly found in the nuclear industry (137Cs, 134Cs and 60Co) in aqueous form. The test can also be adopted for use with other radionuclides and other chemical forms, depending on the customer requirements, if the solutions are chemically stable and do not corrode the test specimen. The test does not measure the ease of decontamination of the surface materials in practical use, as this depends on the radionuclide(s) present, their chemical form, the duration of exposure to the contaminant and the environmental conditions amongst other factors. The test method is not intended to describe general decontamination procedures or to assess the efficiency of decontamination procedures (see ISO 7503-1 to ISO 7503-3). The test method is not suitable for use of radiochemicals if the radionuclide emits low energy gamma rays or beta particles that are readily attenuated in the surface.
