This International Standard specifies the method for measuring rolling circumference for new tyres, under loaded conditions, made for use on agricultural tractors and machines, and applies to agricultural tractor drive wheel tyres in diagonal and radial construction. It also includes an explanation of the Rolling Circumference Index (RCI) and Speed Radius Index (SRI).

This document provides guidelines on the necessary quality assurance required to produce calibration gas mixtures that are demonstrably stable and comparable. It is shown that this is achieved by demonstrating that the composition of the calibration gas mixture is metrologically traceable to the SI. It is shown that calibration gas mixtures can be prepared according to methods that have measurements that are completely described in SI units. Procedures for verifying that the composition of such gas mixtures is correct within the stated measurement uncertainty are described. Guidance is given as to how to conduct the evaluation of uncertainty in these procedures. It is also shown how a calibration gas mixture with unknown composition can be calibrated by reference to traceable standard gas mixtures. This document covers the commonalities and differences of quality management schemes in use by producers of calibration gas mixtures, most notably those described in ISO/IEC 17025 and ISO 17034. These systems lead to calibration gas mixtures with different characteristics, and this standard explains which and their implications. Calibration gas mixtures, as prepared and certified for composition in accordance with this standard are used for the calibration of equipment, the performance evaluation of methods, measurement procedures and equipment.

This European Standard specifies the agreements to be made between the client, the galvanizer / sherardizer, the chemical suppliers and the applicators of the pre-treatment and the powder organic coating systems (if they are not one and the same). It also specifies the quality of the galvanized or sherardized articles to which the powder organic coatings are to be applied and for the pre-treatment and powder organic coatings intended for application to the galvanized or sherardized articles.This standard applies to the application of hot dip galvanized, sherardized and powder organic coatings by controlled industrial processes to articles consisting of or manufactured from steel. The standard applies to hot dip galvanized products, galvanized in accordance with EN ISO 1461 and EN 10240 or products sherardized in accordance with EN ISO 17668, as well as parts of these products manufactured from continuously galvanized sheet and strip galvanized in accordance with EN 10346, which, after the galvanizing and/or assembly, or sherardizing, will have a powder organic coating system applied. This standard also applies to products which have been hot dip galvanized or sherardized according to specific product standards to which powder organic systems are applied.This standard might also be useful when supplying other organic coating systems (excluding wet paint systems).

This document specifies requirements for almandite garnet abrasives, as supplied for blast-cleaning. It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides. The requirements specified in this document apply to abrasives supplied in the “new” condition only. They do not apply to abrasives either during or after use. Test methods for non-metallic blast-cleaning abrasives are given in the various parts of ISO 11127.

This document specifies general methods for determining the resistance of an individual-layer or multi-layer system of coating materials to the effects of liquids, other than water, or paste-like products (included implicitly in test liquids mentioned in the text). These methods enable the testers to determine the effects of the test liquid on the coating and, if necessary, to assess the damage to the substrate.

This part of ISO 2812 specifies a method for determining the resistance of an individual-layer or multi-layer system of coating materials to the effects of water by partial or full immersion. This method enables the determination of the effects of water on the coating and, if necessary, the assessment of the damage to the substrate.

This document specifies spotting methods for determining the resistance of an individual-layer or multi-layer system of coating materials to the effects of liquids or paste-like products. These methods enable the testers to determine the effects of the test substance on the coating and, if necessary, to assess the damage to the substrate.

This International Standard specifies the dimensions and construction of, and requirements for, four types of hose and hose assembly for use in all operations associated with the ground fuelling and defuelling of aircraft. All four types are designed for

This document specifies the requirements for biodegradable films, manufactured from thermoplastic materials, to be used for mulch applications in agriculture and horticulture.This document is applicable to films intended to biodegrade in soil without creating any adverse impact on the environment.It also specifies the test methods to assess these requirements as well as requirements for the packaging, identification and marking of films.For information, it defines a classification of biodegradable mulch films according to their service life on soil and gives a good practice guide for the use of the films.NOTE Films intended to be removed after use and not incorporated in the soil are not in the scope of this standard. They are in the scope of EN 13655 [1].

This document covers the development of specifications for corrosion protection of steel structures using protective paint systems. It relates to new work and maintenance in the workshop or on site and is also applicable to the corrosion protection of individual components. This document covers the corrosion protection of steel structures exposed to different corrosion stresses by environments such as indoors, open-air and immersion in water or burial in soil, as well as special stresses, due for example, to medium or high temperatures. The need for different durability ranges is considered. Steel surfaces that have been hot-dip-galvanized, metal-sprayed, zinc-electroplated or sherardized, and previously painted steel surfaces, are also covered by this document. In this document, reference areas for assessing the quality of the corrosion protection work and the performance of the protective paint systems used are dealt with. This document provides detailed flow charts for planning new work and maintenance, which are taken into account when writing a specification. This document can also be used as a guide if extreme corrosion stresses or high temperatures occur, or if the protective paint systems are to be used on other substrates, such as non-ferrous metals or concrete, to define suitable specifications.
