1.1 General
This Standard details mechanical, physical, and electrical requirements for a newly manufactured non- residential appliance, referred to as a vehicle fueling appliance (VFA), that compresses natural gas for vehicles and dispenses directly into onboard vehicle storage or delivers to external natural gas storage systems.
This Standard applies to appliances that incorporate…
Gas cylinders — Gases and gas mixtures — Determination of tissue corrosiveness for the selection of ...
ISO 13338:2017 provides:
- for pure gases and some liquids, a complete list indicating their corrosiveness;
- for gas mixtures, a calculation method, in the absence of experimental data, relating to the corrosiveness of each of their components;
in order to determine the corrosiveness of gases and gas mixtures on tissue so that a suitable outlet connection can be assigned to each of…
Rubber hoses and hose assemblies for use in oil burners — Specification
ISO 6806:2017 specifies the minimum requirements for rubber hoses and hose assemblies for use in oil burners.
The following two types of hose assembly are specified.

- Type 2: Hose…
Printed board assemblies - Part 2: Sectional specification - Requirements for surface mount soldered...
IEC 61191-2:2017 gives the requirements for surface mount solder connections. The requirements pertain to those assemblies that are totally surface mounted or to the surface mounted portions of those assemblies that include other related technologies (e.g. through-hole, chip mounting, terminal mounting, etc.).<br />
This edition includes the following significant technical changes with…
Performance of high-voltage direct current (HVDC) systems with line-commutated converters - Part 1: ...
IEC/TR 60919-1:2010+A1:2013+A2:2017 provides general guidance on the steady-state performance requirements of HVDC systems. It concerns the steady-state performance of two-terminal HVDC systems utilizing 12-pulse converter units comprised of three-phase bridge (double- way) connections, but it does not cover multi-terminal HVDC transmission systems. Both terminals are assumed to use thyristor…

Bi-directional grid connected power converters - Part 1: General requirements
IEC 62909-1:2017 specifies general aspects of bi-directional grid-connected power converters (GCPC), consisting of a grid-side inverter with two or more types of DC-port interfaces on the application side with system voltages not exceeding 1 000 V AC or 1 500 V DC. In special cases, a GCPC will have only one DC-port interface, which is connected to a bidirectional energy-storage device. This…
