Road vehicles — Media Oriented Systems Transport (MOST) — Part 6: Data link layer
This document specifies technical requirements related to the MOST data link layer functionality.
A MOST network is comprised of two or more nodes connected through a physical layer. The data link layer functionality is provided by each node. On each network, all nodes are synchronised and one node provides the system clock. This node is the TimingMaster, while all other nodes are TimingSlaves.…

Road vehicles — H-point machine (HPM-II) — Specifications and procedure for H-point determination
This document provides the specifications and procedures for using the H-point machine (HPM)[1] to audit vehicle seating positions. The HPM is a physical tool used to establish key reference points and measurements in a vehicle. The H-point design tool (HPD) is a simplified computer-aided design (CAD)[2] version of the HPM, which can be used in conjunction with the HPM to take the optional…
Road vehicles — Compressed natural gas (CNG) fuel system components — Part 14: Excess flow valve
This document specifies tests and requirements for the excess flow valve, a compressed natural gas (CNG) fuel system component intended for use on the types of motor vehicles defined in ISO 3833.
This document is applicable to vehicles (mono-fuel, bi-fuel or dual-fuel applications) using natural gas in accordance with the ISO 15403 series.
It is not applicable to the following:
a) liquefied…
This document sets out the designation, contours and dimensions for rims for narrow- and wide-base off-road tyres primarily intended for earth-moving machinery.
All dimensions in this document are given in millimetres and are applicable to the side of the rim which is in contact with the tyre.
Tyre designations and dimensions, tyre classifications and nomenclature are given in ISO 4250-1, ISO…
1 Scope
This International Standard specifies safety requirements for electric toys that have at least
one function dependant on electricity, electric toys being any product designed or intended,
whether or not exclusively, for use in play by children under 14 years of age.
NOTE 1 Examples of electric toys also within the scope of this standard are
– constructional sets;
– experimental sets…
