This Document specifies the requirements and the corresponding methods of test for raw, refined and boiled linseed oils for paints and varnishes.

This European Standard specifies requirements for two types of thermoplastic multi-layer (non-vulcanized) transfer hoses and hose assemblies for carrying liquefied petroleum gas and liquefied natural gas. Each type is subdivided into two classes, one for onshore duties, and the other for offshore.This European Standard is applicable for hose sizes from 25 mm to 250 mm, working pressures from 10,5 bar to 25 bar and operating temperatures from - 196 °C to + 45 °C.NOTE Offshore LNG hose assemblies are also specified in EN 1474-2.WARNING - Persons using this European Standard should be familiar with normal laboratory practice. This standard does not purport to address all the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate health and safety practices and to ensure compliance with any national regulatory conditions.

This European standard specifies an analytical method, based on liquid-chromatography (LC) with ultraviolet/visible spectrometry (UV/Vis) detection for the detection and quantitative determination of the currently 22 organic UV filters in use in the EU framework. This method has been validated for emulsion-based cosmetic products, lip-balms, lotions and waters.

This International Standard specifies requirements for a chain of custody (CoC) of wood and wood-based products, cork and lignified materials other than wood, such as bamboo, and their products. This International Standard applies to material that originates from different categories of sources and may be derived from mechanical, chemical or biological processing or a combination thereof. A chain of custody relies on a control system to track and handle material throughout the entire or parts of the supply chain including transportation, receipt, production, sale, resale and output declaration. This International Standard is intended to enable tracking of material from different categories of sources to finished products. Furthermore, this International Standard also specifies minimum requirements for input material. This International Standard is not applicable to forest management.

This part of ISO 7263 describes a method for the determination of the flat crush resistance of a corrugating medium after laboratory fluting using an A-flute geometry. The procedure is applicable to any corrugating medium intended to be used, after fluting, in the manufacture of corrugated board.

This part of ISO 7263 describes a method for the determination of the flat crush resistance of a corrugating medium after laboratory fluting using a B-flute geometry. The procedure is applicable to any corrugating medium intended to be used, after fluting, in the manufacture of corrugated board.

This European Standard describes a test method to evaluate the performance of photocatalytic materials in water purification by measuring phenol degradation. This test method is applicable to photocatalytic materials in form of powders (suspensions in water, slurries) under UV irradiation. The photocatalytic performance of the tested material is assessed by the observed rate of phenol degradation at specified experimental conditions as determined by HPLC.

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 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 European Standard specifies the design, materials and dimensions of fittings for clamp type coupling assemblies for use with nominal sizes DN 15 to DN 50 steam and hot water hoses. It covers assemblies up to a maximum working pressure of 18 bar ) (corresponding to a saturated steam temperature of 210 °C).
