This document specifies the requirements and definitions for the essential characteristics of prestressing bars, which are used for the prestressing of concrete and which are delivered as finished products in the form of: - hot rolled and processed bars; - plain and threaded bars. NOTE 1 The specification of manufacturing processes related to the finished product is required to ensure that the essential characteristics can be tested properly and that test results are valid. It is not possible to anticipate that any other manufacturing process leads to products which can be tested properly with the specified test methods. Thus, a conclusion to the safe application in building construction would not any longer be possible for those products. This document does not apply to: - galvanized steel; - epoxy coated steel; - reinforcing steel (see EN 10080); - further processing. NOTE 2 Example for further processing: Plain bars are also applied in systems for the prestressing of concrete with threaded ends. The threaded ends depend in length and type on the intended use of the system and are manufactured downstream in the supply chain.

 

ISO 5210:2017 specifies the requirements for the attachment of multi-turn actuators to valves. Throughout this document, "actuator" may be understood as "actuator and/or gearbox" providing a multi-turn and/or linear output. ISO 5210:2017 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.

 

This document specifies requirements for non-alloy and alloy steels that are intended for cold heading or cold extruding and are delivered as wire rods, wire or bars. It also contains specific requirements for: This document (except Annex A) is applicable to the properties of cold-headed or cold-extruded parts which have been subjected to a subsequent heat treatment. As the properties of the parts in the cold-headed or cold-extruded, and subsequently not-heat-treated condition, are largely dependent on the applied cold-heading or cold-extruding conditions, these are, if necessary, subject to agreement between the purchaser and the manufacturer of the parts.

 

This document specifies requirements for stainless steels that are intended for cold heading or cold extruding and are delivered as wire rods, wire or bars. It contains specific requirements for steels with diameters of 0,8 mm up to 50 mm for austenitic steels, up to 25 mm for ferritic steels and up to 100 mm for martensitic steels. This document is applicable to the properties of cold-headed or cold-extruded parts which have been subjected to a subsequent heat treatment. As the properties of the parts in the cold-headed or cold-extruded, and subsequently not-heat-treated condition, are largely dependent on the applied cold-heading or cold-extruding conditions, these are, if necessary, subject to agreement between the purchaser and the manufacturer of the parts.

 

This document describes the technology of biological exhaust air purification. For a better understanding, the most important process principles of this method are described first. Then based on this, the relevant requirements for a possible application are specified. Furthermore, the different variants of this technique are presented.

 

This document gives guidance on the design of work systems, including task and equipment design (comprising robotics and intelligent autonomous systems) and design of the workplace, as well as working conditions with the inclusion of social and organisational factors, emphasizing mental workload and its effects, as specified in ISO 10075-1. It applies to the adequate design of work and use of human capacities, with the intention to provide for optimal working conditions with respect to health and safety, well-being, performance, and effectiveness, preventing over- as well as underload, in order to avoid the impairing effects and to foster the facilitating effects described in ISO 10075-1. Mental workload is the effect of a complex interaction of individual, technical, organizational and social factors. Thus personnel, technical, organizational and social factors and the effects of their interactions have to be taken into account in the design of work systems. However, this document includes the design of technical, organizational and social factors only and does not apply to problems of selection or training. This document provides guidelines for system design. It does not address problems of measurement of mental workload or its effects. This document refers to all kinds of human work activities (see ISO 10075-1), not only to those which would be described as cognitive or mental tasks in a restricted sense, but also to those with primarily physical workload. This document is thus relevant to all those engaged in the design and use of work systems, e.g. system and equipment designers, employers' and workers' representatives. This document is applicable to the design of new work systems as well as to the redesign of existing ones undergoing substantial revision.

 

This International Standard specifies the minimum characteristics of instruments for measuring physical quantities characterizing an environment as well as the methods for measuring the physical quantities of this environment. Its aim is simply to standardize the process of recording information leading to the determination of values of physical quantities. Other International Standards give details of the methods making use of the information obtained in accordance with this standard. This International Standard is used as a reference when establishing It applies to the influence of hot, moderate, comfortable or cold environments on people. This Standard is applied in the cases in which comfort or human strain are the main concern and may be supersedes by other Standards.

 

 

This document is applicable to aluminium-based coagulants used for treatment of water intended for human consumption. It specifies analytical methods to be used for products described in EN 878, EN 882, EN 885, EN 886, EN 887, EN 935 and EN 17034.

 

 

ISO 3887:2017 defines the decarburization and specifies three methods of measuring the depth of decarburization of steel products.
