Information technology — Object management group systems modeling language (OMG SysML)
The purpose of ISO/IEC 19514:2017 is to specify the Systems Modeling Language (SysML), a general-purpose modeling language for systems engineering. Its intent is to specify the language so that systems engineering modelers may learn to apply and use SysML; modeling tool vendors may implement and support SysML; and both can provide feedback to improve future versions. Note that a definition of…
ISO 18135:2017 describes methods for preparing sampling plans and certificates, as well as taking samples of solid biofuels, for example, from the place where the raw materials grow, from production plant, from deliveries, e.g. lorry loads, or from stock. It includes both manual and mechanical methods, and is applicable to solid biofuels that are either:
- fine (particle sizes up to about 10…
ISO 12494:2017 describes the general principles of determining ice load on structures of the types listed in this clause.
In cases where a certain structure is not directly covered by this or another standard or recommendation, designers can use the intentions of this document. However, it is the user's responsibility to carefully consider the applicability of this document to the structure…
Plastics — Poly(vinyl alcohol) (PVAL) materials — Part 1: Designation system and basis for specifica...
ISO 15023-1:2017 establishes a system of designation for poly(vinyl alcohol) (PVAL) materials which may be used as the basis for specifications.
The types of poly(vinyl alcohol) (PVAL) materials are differentiated from each other by a classification system based on the designatory properties:
a) degree of hydrolysis,
b) viscosity of aqueous solution under defined conditions
and on…
ISO 8217:2017 specifies the requirements for fuels for use in marine diesel engines and boilers, prior to conventional onboard treatment (settling, centrifuging, filtration) before use. The specifications for fuels in this document can also be applied to fuels used in stationary diesel engines of the same or similar type as those used for marine purposes.
ISO 8217:2017 specifies seven categories…
Explosive atmospheres - Part 32-1: Electrostatic hazards - guidance
IEC TS 60079-32-1:2013+A1:2017 gives guidance about the equipment, product and process properties necessary to avoid ignition and electrostatic shock hazards arising from static electricity as well as the operational requirements needed to ensure safe use of the equipment, product or process. It can be used in a risk assessment of electrostatic hazards or for the preparation of product family or…

ISO 20028-1:2017 establishes a system of designation for thermoplastic polyester (TP) material, which can be used as the basis for specifications. It covers polyester homopolymers for moulding and extrusion based on poly(ethylene terephthalate) (PET), poly(butylene terephthalate) (PBT), poly(cyclohexylenedimethylene terephthalate) (PCT), poly(ethylene naphthalate) (PEN), poly(butylene…
Fibre optic communication subsystem test procedures - Part 4-4: Cable plants and links - Polarizatio...
IEC 61280-4-4:2017 provides uniform methods of measuring polarization mode dispersion (PMD) of single-mode installed links. An installed link is the optical path between transmitter and receiver, or a portion of that optical path. These measurements can be used to assess the suitability of a given link for high bit rate applications, or to provide insight on the relationships of various related…
