Naftos ir dujų pramonė, įskaitant mažesnio anglies dioksido pėdsako energijos gamybą. Viso žiedo ovalėjimo bandymo metodas plieninių vamzdynų atsparumui pleišėjimui rūgštinėje aplinkoje įvertinti (ISO 3845:2024)

This document gives a method for determining the resistance to cracking of steel pipes in sour service. This test method employs a full-scale test specimen consisting of a short length of pipe (a ‘full ring’), sealed at each end to contain the sour test environment within. The test method applies to any pipe; seamless, longitudinally welded (with or without filler), helical welded, and to girth welds between pipes. NOTE 1 The specimen is usually a pipe but can also consist of flange neck or section of a bend, or other tubular component or a combination of the above. NOTE 2 This test method can also be used for corrosion resistant alloys (CRAs). The method utilizes ovalization by mechanical loading to produce a circumferential stress, equal to the target hoop stress, at two diametrically opposite locations on the inside surface of the test specimen. The test specimen is then subjected to single sided exposure to the sour test environment. NOTE 3 The test also allows measurement of hydrogen permeation rates.

Aerospace series - LOTAR - Long Term Archiving and Retrieval of digital technical product documentation such as requirements, architecture, simulation, and analytical data - Part 500: Fundamentals and Concepts for Long Term Archiving to enable Model-based Systems Engineering

1.1 In Scope The EN 9300-5xx series specifies the methods for long term archiving and retrieval of MBSE data represented as digital models. The characterization of models that are considered in scope of this document and the MBSE process use cases include: - product or system design requirements models; - functional architecture models; - logical architecture models (system structure, arrangement, connectivity, software allocations and controls, and part relationships); - numerically-based system analysis and simulation models, generally regulated 1D control loop models featuring system components and transport elements (tubing, piping, signalling, software); - verification and validation of requirements; - protocol dependent signal or communication networks; - multi-model linking and system parametric models; - system trade study models; - the solution architecture models and data that are needed to implement the system and generate system engineering data for downstream designs. 1.2 Out of Scope The EN 9300-5xx series does not address the original product model design process, or a specific configuration management process for the LOTAR archive. It does not address models depicting part specific technical data (physical materials or detail part standards). It is assumed that these archiving processes are within the scope of other parts of the EN 9300 series such as the 1xx series for CAD, the 2xx series for Product Data Management (PDM) data, or by applying existing alternative industry standards, or existing company business procedures. Typical models and capabilities considered out of scope of this document include: - physical spatial models or composite structures (as described by other LOTAR Parts); - Finite Element and CFD models (as described by other LOTAR Parts); - Product Data Management models (as described by other LOTAR Parts); - electrical circuit boards, or physical wiring parts or systems (described by other LOTAR Parts or standards); - the software development process and software models that are outside of the context of software parts, behaviours, or functions that represent software code within a model; - how to preserve property and access rights, or government acquisition-regulatory controls; - new standards, or major revisions to existing MBSE standards that were not available or applicable prior to the publication of this document.

This document specifies dimensions, materials and performance requirements, including test methods, for combined temperature and pressure relief valves, of nominal sizes from DN 15 to DN 40, having working pressures ) from 0,3 MPa (3 bar) to 1,0 MPa (10 bar). Combined temperature and pressure relief valves control and limit the temperature and pressure of the water contained in a hot water heater to the valves rating pressure and a temperature not exceeding 100 °C and will prevent water to steam formation when other temperature controls fail. Combined temperature and pressure relief valves are classified having a maximum opening temperature range from 90 °C to 95 °C for class A and 75 °C to 80 °C for class B. They are not intended to act as an expansion valve and do not control cold water flow. Alone it does not constitute the control functions for a water heater. A combined temperature and pressure relief valve is an independently mechanically operating device, therefore operating without an external energy source. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information, see Annex B).
