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…
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 1: Hose assemblies for flux and reflux, but not for insertion between the oil burner pump and the atomizing connection; maximum working pressure 1,0 MPa (10 bar); maximum oil temperature 100 °C.
- 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…
