This document defines an integrated approach for the validation of a quantitative analytical method, based on the construction and interpretation of an accuracy profile, and specifies its characterization procedure. This procedure is particularly applicable for internal validation in a cosmetic testing laboratory, but its scope can be extended to the interpretation of data collected for an interlaboratory study designed according to the recommendations of the ISO 5725-1. It does not apply to microbiological trials. The present approach is particularly suited to handle the wide diversity of matrices in cosmetics. This document only applies to already fully-developed and finalized methods for which selectivity/specificity have already been studied and the scope of the method to be validated has already been defined, in terms of matrix types and measurand (for example analyte) concentrations.

 

This document specifies the requirements for three types of general-purpose textile-reinforced rubber water hose with an operating temperature range of -25 °C to +70 °C and a maximum working pressure of up to 2,5 MPa (25 bar). These hoses are not intended to be used for conveyance of potable (drinking) water, for washing-machine inlets, as firefighting hoses, for special agricultural machines or as collapsible water hoses. These hoses can be used with additives which lower the freezing point of water.

 

This document provides guidance for the design, manufacture, and testing of pressure vessels to meet the performance criteria at the time of installation for the stationary storage of gaseous hydrogen. Pressure vessels fabricated of seamless metallic or welded construction (Type 1) or of composite construction (Types 2, 3, 4), regardless of reinforcement (metallic or non-metallic), are covered by this standard. This standard can be applied to pressure receptacles as defined in iso:pub:std:FDIS:79732ISO 10286:2021within the volume and pressure limits provided below. This document is not applicable to pressure vessels used for: a) solid storage matrix for hydrogen, b) liquid hydrogen, c) hybrid cryogenic high-pressure hydrogen storage applications, d) or on-board vehicle storage. This document is not applicable to closures, valves, fittings, plugs or external piping.

 

This document describes methodologies that can be applied to estimate the greenhouse gas (GHG) emissions associated with the conditioning, storage and transport of gaseous and liquid hydrogen up to the consumption gate. GHG emissions from cradle to gate (well-to-consumption gate) in the hydrogen supply chain can be assessed by combining iso:proj:88686ISO/DIS 19870-1, which defines methodologies for determining the GHG emissions associated with various pathways of hydrogen production, with this document. ISO 14044 [3] requires the goal and scope of a life cycle assessment (LCA) be clearly defined and be consistent with the intended application. Due to the iterative nature of LCA, it is possible that the LCA scope needs to be refined during the study. According to ISO 14040:2006 [4], Annex A2, the goals and scope of LCAs correspond to one of the following two approaches: a) an approach that assigns elementary flows and potential environmental impacts to a specific product system, typically as an account of the history of the product (see 4.1.2); b) an approach that studies the environmental consequences of possible (future) changes between alternative product systems (see 4.1.3). In this document, approach a) is referred to as an attributional approach, while approach b) is referred to as consequential approach. Complementary information is accessible in the ILCD handbook[5]. A carbon footprint of a product or partial CFP as defined by iso:proj:71206ISO 14067 can be estimated using either the attributional or the consequential approach, the latter corresponding to the use of “system expansion via substitution” to avoid allocation when a unit process yields multiple co-products.

 

This document describes methodologies that can be applied to estimate the greenhouse gas (GHG) emissions associated with the production of ammonia, its storage and transport, and the conversion of ammonia into hydrogen. The transport of hydrogen from the ammonia cracking facility to any delivery point up to the hydrogen consumption gate is covered in ISO 19870-2 (see Figure 2). This document describes in the annexes the requirements and evaluation methods applied to several ammonia production pathways of interest. It also describes the requirements and evaluation methods applied to several ammonia cracking pathways of interest. This document considers the GHG emissions associated with ammonia production up to the delivery gate. This document applies to and includes every steps from ammonia production to any ammonia delivery gate and to ammonia cracking. ISO 14044 requires the goal and scope of an LCA to be clearly defined and be consistent with the intended application. Due to the iterative nature of LCAs, it is possible that the LCA scope needs to be refined during the study. The goals and scopes of the methodologies correspond to either approach a) or b), given below, that iso:proj:37456ISO 14040:2006, Annex A2 gives as two possible approaches to LCAs. a) An approach that assigns elementary flows and potential environmental impacts to a specific product system, typically as an account of the history of the product. See 4.1.2. b) An approach that studies the environmental consequences of possible (future) changes between alternative product systems. See 4.1.3. In this document, approach (a) is referred to as an attributional approach, while approach (b) is referred to as a consequential approach. Complementary information is accessible in the ILCD handbook [1]. A Carbon Footprint of a Product or Partial Carbon Footprint of a Product as defined by ISO 14067 may be estimated using either the attributional or the consequential approach, the latter corresponding to the use of “system expansion via substitution” to avoid allocation when a unit process yields multiple co-products. Complementary documents in the ISO 19870-X series will consider hydrogen production and other conditioning, conversion and transport methods.

 

 

This document specifies design, type testing, marking and manufacturing tests and examinations requirements for: a) self-closing cylinder valves; b) self-closing cylinder valves with integrated pressure regulator (VIPR); for refillable transportable gas cylinders which convey compressed, liquefied or dissolved gases. NOTE 3 The main applications for such self-closing cylinder valves are in the calibration gas and beverage industries. NOTE 4 Where there is no risk of ambiguity, cylinder valves and VIPRs are addressed with the collective term “valves” within this document. This document does not apply to: — valves for cryogenic equipment, portable fire extinguishers and liquefied petroleum gas (LPG); — quick-release cylinder valves (e.g. for fire-extinguishing, explosion protection and rescue applications) - requirements for quick-release cylinder valves are specified in ISO 17871 which contains normative references to this document; — ball valves. NOTE 5 Requirements for valves for cryogenic vessels are specified in ISO 21011 and at a regional level, e.g. in EN 1626. Requirements for valves for portable fire extinguishers are specified at a regional level, e.g. in EN 3 series. Requirements for self-closing LPG cylinder valves are specified in ISO 14245. Requirements for quick-release cylinder valves are given in ISO 17871. Requirements for ball valves are given in ISO 23826. This document only covers the function of a valve as a closure. Other functions that are possibly integrated in the valve can be covered by other standards. Such standards do however not constitute requirements according to this document. NOTE 6 Definition of and specific requirements for VIPRs in addition to those that are given in this document are specified in ISO 22435 for industrial applications or ISO 10524-3 for medical applications. Similarly, certain specific additional requirements for residual pressure valves (RPV) are given in ISO 15996.

 

 

This document specifies the procedure for the determination/calculation of the dry matter content of inorganic fertilizers for which the results of the performed analysis are expressed in relation to the dry residue.

 

This document specifies the procedure for the extraction of different organic and organo-mineral fertilizers with 2 % formic acid (20 g/l) to enable a subsequent determination of phosphorus, representing the amount of soft natural phosphates. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: organic fertilizers, organo-mineral fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If the organic fertilizer or the organo-mineral fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.

 

This document specifies a method for the determination of the biuret content by high-performance liquid chromatography (HPLC) with ultraviolet (UV) detector. This document is applicable to organic and organo-mineral fertilizers containing urea. This document is applicable to fertilizing products blends where a blend is a mix of at least two of the following products: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants and where organic matter is present in at least one of the products in the blend. In case a fertilizing product blend is composed only of inorganic products, the European Standard for inorganic fertilizers applies. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible. NOTE 1 This method was tested only for one fertilizing product blend during the inter-laboratory study. The product tested was a liquid organo-mineral mixture of a liquid organic fertilizer, a growing medium and a non-microbial plant biostimulant. NOTE 2 Nowadays, there is a method standardized as EN 15479 that allows the determination of biuret in urea by spectrophotometric detection. Organic and organo-mineral fertilizers contain organic matter and other compounds apart from urea that would interfere in a spectrophotometric method. HPLC allows an accurate determination of biuret by separating it from possible interfering compounds [2] [5].
