The definitive intention of ISO 14532:2014 is to incorporate the reviewed definitions into the ISO/TC 193 source standards.

 

This document provides an inventory of best practices, shared by actors from the aerospace and defence sector, concerning the verification and validation (V&V) of numerical simulations and models, in order to ensure the credibility of the outputs obtained in a logic of faster development of decision-making support, of reducing the number of physical tests, of shortening development times, of facilitating numerical qualification and certification, etc. These are all the major challenges concerning simulation. The approach applies to models based on physical equations. EXAMPLE Mechanics, acoustics, electrical, electromagnetism, thermal physics for electronics, fluid dynamics, multibody dynamics, multiphysics, optical, signal integrity and power integrity. The objective is to determine recommendations depending on the challenges of the simulation, in order to adapt the procedures to be applied to ensure the credibility of the simulation. The items being considered are: - criticality of the product and the simulation; - complexity of the phenomenon or the product; - capability, fidelity and maturity of the model; - product lifecycle; - skills; - verification and validation approach, with uncertainties quantification; - etc. This document is organized as follows: - terms and definitions; - general principles and concepts of simulation V&V: o the document’s objectives and added value; o state of the art; o different uses of simulation depending on the maturity (approximation level) of the model and product lifecycle, linked to the expected fidelity of the model and the simulation outputs; o presentation of the different types of models and impacts on criteria and quantities of interest, as well as on requirements; - recommended V&V process and activities (linked to the degree of maturity); - an example of a simulation plan template; - examples for a clearer understanding. The aim of this document is to complete and reference the information available in the literature. This document takes a generic approach so that it is applicable by most organizations and for different types and domains of simulation. This document addresses simulation specialists, simulation team managers and other stakeholders involved in the simulation process or decision-making support. This document provides recommendations for each criticality level, linked also to the level of confidence in the simulation, at each stage of the simulation process. Modelling and simulation have long been part of product qualification and certification, and the recommendations laid down in this document do not aim to replace the many qualification, certification and analysis processes already proven and established. The practices recommended in this document were specifically developed in response to potential future applications of modelling and simulation which could, in some cases, give it a more prominent role in qualification and certification, thereby reducing programme costs and development times.

 

This International Standard specifies a test method for the determination of the flash point of chemicals, lube oils, aviation turbine fuel, diesel fuel, diesel/biodiesel blends and other liquids by a continuously closed cup tester utilizing a specimen size of 2 ml, cup size of 7 ml, with a heating rate of 2.5 °C per minute. This flash point test method is a dynamic method and depends on definite rates of temperature increase. It is one of the many flash point test methods available and every flash point test method, including this one, is an empirical method. It utilises an electric arc as the ignitor and detects the flash point by pressure measurement.This test method is suitable for testing samples with a flash point from 22,5 °C to 235,5 °C. Flash point determinations below 22,5 °C and above 235,5 °C may be performed, but the precision has not been determined.

This document describes the concept of production assurance within the systems and operations associated with exploration drilling, exploitation, processing and transport of petroleum, petrochemical and natural gas resources. This document covers upstream (including subsea), midstream and downstream facilities, petrochemical and associated activities. It focuses on production assurance of oil and gas production, processing and associated activities and covers the analysis of reliability and maintenance of the components. This includes a variety of business categories and associated systems/equipment in the oil and gas value chain. Production assurance addresses not only hydrocarbon production, but also associated activities such as drilling, pipeline installation and subsea intervention. This document provides processes and activities, requirements and guidelines for systematic management, effective planning, execution and use of production assurance and reliability technology. This is to achieve cost-effective solutions over the life cycle of an asset development project structured around the following main elements: — production assurance management for optimum economy of the facility through all of its life cycle phases, while also considering constraints arising from health, safety, environment, and quality; — planning, execution and implementation of reliability technology; — application of reliability and maintenance data; — reliability-based technology development, design and operational improvement. The IEC 60300-3 series addresses equipment reliability and maintenance performance in general. This document designates 12 processes, of which seven are defined as core production assurance processes and addressed in this document. The remaining five processes are denoted as interacting processes and are outside the scope of this document. The interaction of the core production assurance processes with these interacting processes, however, is within the scope of this document as the information flow to and from these latter processes is required to ensure that production assurance requirements can be fulfilled. The only requirement mandated by this document is the establishment and execution of the production assurance programme (PAP). It is important to reflect the PAP in the overall project management in the project for which it applies. This document recommends that the listed processes and activities be initiated only if they can be considered to add value.

 

ISO 19008:2016 describes the standard cost coding system (SCCS) that classifies costs and quantities related to exploration, development, operation and removal of oil and gas production and processing facilities and to the petroleum, petrochemical and natural gas industry. Upstream, midstream, downstream and petrochemical business categories are included. The SCCS for coding of costs is applicable to: - cost estimating; - actual cost monitoring and reporting; - collection of final quantities and cost data; - standardized exchange of cost data among organizations; - implementation in cost systems. ISO 19008:2016 is intended for users such as the following: a) owner/operator/company (individual or grouped entity that is entitled or contributes to operations in the exploitation of oil and gas fields); b) industry/trade associations; c) manufacturers/contractors; d) cost engineering service contractors, cost system providers, benchmarking providers, etc.; e) authorities/regulatory bodies. ISO 19008:2016 does not apply to the following: 1) cost classification relevant to cost accounting rules, specific contractual agreements, local requirements for cost reporting to national bodies, government rules and tax regulations, authorization for expenditure (AFE), billing purposes etc.; 2) specific project breakdown structures (e.g. work breakdown structures, contract breakdown structures, organizational breakdown structure) or asset breakdowns (e.g. TAG/system codes, area/module breakdown structure) which are and will remain unique. However, this International Standard can provide a basis for the establishment of such specific classification systems.
