Software, systems and enterprise — Architecture processes
This document establishes a set of process descriptions for the governance and management of a collection of architectures and the architecting of entities. This document also establishes an enablement process description that provides support to these other architecture processes.
The processes defined in this document are applicable for a single project, as well as for an organization…
Water quality — Determination of biochemical oxygen demand after n days (BODn) — Part 1: Dilution an...
This document specifies the determination of the biochemical oxygen demand of waters by dilution and seeding with suppression of nitrification after 5 d or 7 d incubation time.
It is applicable to all waters having biochemical oxygen demands usually between 1 mg/l and 6 000 mg/l. It applies particularly to waste waters but also suits for the analysis of natural waters. For biochemical oxygen…
Systems and software engineering — Taxonomy of systems of systems
This document defines a normalized taxonomy for systems of systems (SoS) to facilitate communications among stakeholders. It also briefly explains what a taxonomy is and how it applies to the SoS to aid in understanding and communication.
Systems and software engineering — Content of life-cycle information items (documentation)
This document specifies the purpose and content of all identified systems and software life‐cycle and service management information items (documentation). The information item contents are defined according to generic document types, as presented in Clause 7, and the specific purpose of the document, as presented in Clause 10.
This document assumes an organization is performing life‐cycle…

Systems and software engineering - System of systems (SoS) considerations in life cycle stages of a ...
1.1 Purpose This document provides a set of critical system of systems (SoS) considerations to be addressed at key points in the life cycle of the system of interest (SoI). This document refers to considerations that apply to an SoI that is a constituent system that interacts in an SoS. The considerations and life cycle model align with those which are already defined in ISO/IEC/IEEE 15288 and…

Reciprocating internal combustion engines — Exhaust emission measurement — Part 9: Test cycles and t...
This document specifies the measurement procedures and test cycles for the evaluation of smoke emissions from compression ignition engines using an opacimeter. The tests are carried out under steady-state and transient operation using tests cycles which are representative of a given application.
The smoke testing is conducted using opacimeter-type smoke meters which operate on the light…
