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.

 

ISO 20492-1 specifies two methods for testing the durability of edge seals of insulating glass units by means of climate tests: the final frost/dew point method and the moisture-penetration index method. This document is applicable to pre-assembled, permanently sealed, insulating glass units with one or two cavities, and with capillary tubes that are intentionally left open to equalize pressure inside the unit with the surrounding atmosphere. This document is not applicable to sealed, insulating glass units that contain a spandrel glass coating. This document does not apply to insulating glass (IG) units whose function is decorative only.

ISO 20492-4 specifies methods for testing the edge seal strength, and partially testing the water and gas permeation through sealants, of glass insulating units. Other parts of ISO 20492 designate two approaches to the standardization of insulating glass units. The methods in ISO 20492-4 are applicable only to approach 2, as defined and used in the other parts of ISO 20492. In cases where there is no protection against direct ultraviolet radiation at the edges, such as structural sealant glazing systems, it is necessary that additional European technical specifications be followed. See References [4] and [5].

 

 

In general terms, Miner’s rule is a common approach to calculate how the accumulation of a specific load that varies over time effects the time until failure. This international standard specifies the application of Miner’s rule for calculating the design time until failure of plastics pipes and piping systems of plastics materials under varying, but known, load conditions. Miner’s rule can also be applied reciprocally to calculate the tolerable load levels along a desired design time. This international standard specifies particularly the application of Miner’s rule to calculate stress or pressure regimes, respectively, that are tolerable during a targeted design time for plastics or composite pipes. Further, the application of Miner’s rule on the effect of accumulated damage on polyolefins caused by oxidative attack under varying temperatures and times on the design life is specified. It is necessary to apply Miner's rule to each failure mechanism separately. Thus, for mechanical failure due to internal pressure, other failure mechanisms, such as oxidative or dehydrochlorinative degradative failure mechanisms, are to be neglected (assuming, of course, no interaction). A material may be used only when it is proven to conform to all failure mechanism criteria. NOTE Miner's rule is an empirically based procedure and is only a first approximation to reality.

 

This document specifies a test method to determine if a fitting will fail in crushing mode under compression before a predefined percentage deformation of moulded fittings for thermoplastics piping systems and recommends a specification (see annex A).
