This standard applies to two grades of kerosene-type aviation turbine fuel (grades JET A and JET A-1), consisting
of conventional hydrocarbons, synthetic hydrocarbons, naturally occurring non-hydrocarbons and additives as
specified herein.
The fuels are normally used in civil aviation operations. The two grades differ only in freezing point. Grade JET A
has a maximum freezing point of -40°C…
Methods of testing petroleum and associated products Visual haze rating of liquid fuels
This test method describes two procedures for the visual haze rating or appearance of contamination of liquid fuels
with an ASTM colour rating of 5 or less, and a cloud point below the reported temperature of the test.
The testing and evaluation of a product against this method requires the use of materials and/or equipment that
could be hazardous. This document does not purport to address all…
Low-voltage switchgear and controlgear — Controllers for drivers of stationary fire pumps
1 Scope and object
This International Standard applies to controllers intended for starting, controlling and stopping stationary
fire pumps, including automatic and non-automatic types for alternating current electric motor or diesel
engine-driven fire pumps. It is anticipated that a controller only controls a single driver.
Controllers for electric motor-driven fire pumps always include…
