This document considers the GHG emissions associated with the storage, transport, and release of hydrogen via LOHC. This document applies to and includes every step within the scope of storing, transporting, and releasing hydrogen via LOHC within a hydrogen supply chain (see Figure 2 in the Introduction). According to ISO 14040:2006, Annex A2, the goals and scope of LCAs correspond to one of the following two approaches: 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 LCA. 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 Section 4.1.2. b) An approach that studies the environmental consequences of possible (future) changes between alternative product systems. See Section 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 [1]. A carbon footprint of a product CFP or partial CFP as defined by iso:proj:71206ISO 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. This document applies to the partial CFP for the storage, transport, and release of hydrogen via LOHC. Complementary documents in the ISO 19870-X series will consider hydrogen production and other conditioning, conversion and transport methods.This document considers the GHG emissions associated with the storage, transport, and release of hydrogen via LOHC.

This document gives guidelines for the content, security, issuance, traceability and examination of physical tax stamps and marks used to indicate that the required taxes identified with an item have been paid, and to signify that the item is legitimately on the intended market. Specifically, this document gives guidance on: the functions of a tax stamp; identifying and consulting with stakeholders; the procurement process and selection of suppliers; the design and construction of tax stamps; the overt and covert security features that provide protection of the tax stamp; the finishing and application processes for the tax stamp; security of the tax stamp supply chain; serialization and unique identifier (UID) codes for tax stamps; traceability; examination of tax stamps; monitoring and assessing tax stamp performance. This document is applicable only to tax stamps that are apparent to the human senses of sight (with the aid of a revealing tool if necessary) or touch, which are applied to an item or its packaging, This may be as an affixed label or seal, as a design supplied in a print-ready electronic file, or as a set of printed or blazed characters, all of which need to be capable of being authenticated. The term “authentication” in this document refers only to the authentication of the tax stamp, not to the product on which the tax stamp is affixed. This document does not apply to systems or procedures that an issuing authority has in place to control and monitor its revenue collection, except by reference to them where they have an impact on the design or specification of tax stamps.

 

This document specifies the sharpness and wear resistance of knives, which are designed for professional and domestic use in the preparation of food of all kinds, specifically of those knives intended for hand use. This document describes test methods for sharpness measurement and for the evaluation of wear resistance of the cutting edge. This document does not apply for hunting knives, pocket knives, razors or tool or utility knives (with trapezoidal blade for cutting carpets etc.). Knives with special shapes, e.g. herb chopping knives or highly curved boning knives, can only be tested in the style of this document since not all properties and test methods are applicable in a meaningful manner.

This document provides a procedure for the evaluation of irradiation data in the region between the reactor core and the inside surface of the containment vessel, through the pressure vessel and the reactor cavity. NOTE These irradiation data could be neutron fluence or displacements per atom (dpa), and Helium production. The evaluation employs both neutron flux computations and measurement data from in-vessel and cavity dosimetry, as appropriate. This document applies to pressurized water reactors (PWRs), boiling water reactors (BWRs), and pressurized heavy water reactors (PHWRs). This document also provides a procedure for evaluating neutron damage properties at the reactor pressure vessel and internal components of PWRs, BWRs, and PHWRs. Damage properties are focused on atomic displacement damage caused by direct displacements of atoms due to collisions with neutrons and indirect damage caused by gas production, both of which are strongly dependent on the neutron energy spectrum. Therefore, for a given neutron fluence and neutron energy spectrum, calculations of the total accumulated number of atomic displacements are important data to be used for reactor life management.

 

This document specifies fundamental techniques of film and digital radiography with the object of enabling satisfactory and repeatable results to be obtained economically. The techniques are based on generally recognized practice and fundamental theory of the subject. This document applies to the radiographic examination of steel pipes for service induced flaws such as corrosion pitting, generalized corrosion and erosion. Besides its conventional meaning, “pipe” as used in this document is understood to cover other cylindrical bodies such as tubes, penstocks, boiler drums and pressure vessels. Complex geometry components such as bends and tees can present additional challenges that can complicate their inspection by the techniques described in this document. Weld inspection for typical welding process induced flaws is not covered, but weld inspection is included for corrosion/erosion type flaws. The pipes can be insulated or not, and can be assessed where loss of material due, for example, to corrosion or erosion is suspected either internally or externally. This document covers the tangential inspection technique for detection and through-wall sizing of wall loss, including with the source: a) on the pipe centre line; and b) offset from pipe centre line by the pipe radius. This document covers double wall radiography, and note that the double wall double image technique is often combined with tangential radiography with the source on the pipe centre line. This document applies to tangential radiographic inspection using industrial radiographic film techniques, computed radiography (CR) and digital detector arrays (DDA).

This document specifies a method for the enumeration of Escherichia coli (E. coli) in soil improvers and growing media. This document is applicable to material in solid form (including pre-shaped growing media) and liquid form. This document is applicable to fertilizing product blends, where a blend is a mix of two or more fertilizing products belonging to the categories of fertilizers, liming material, soil improvers, growing media, inhibitors and plant biostimulants, and where soil improvers and/or growing media comprise the highest percentage in the blend by mass or volume, or in the case of liquid form by dry mass. If soil improvers and/or growing media do not comprise the highest percentage in the blend, the European Standard for the highest percentage in the blend applies. In case a blend is composed of fertilising products in equal quantity, the user of the standard decides which standard to apply. NOTE 1 A soil improver or a growing medium consists of a single bulky (volume-building) component or a mix of bulky (volume-building) components (for example peat, wood fibres, coconut coir, compost, expanded perlite). Strains of E. coli which do not grow at 44 °C ± 1 °C and, in particular, those that are ß-D-glucuronidase-negative, such as E. coli O157, will not be detected. Some strains of Shigella spp. and Salmonella spp. within the family Enterobacteriaceae can also show ß-D-glucuronidase activity at 44 °C ± 1 °C. NOTE 2 This method has been validated in an interlaboratory study with specific products that were present on the market during the study (Annex C).
