This part specifies categories of use for optical coatings and…
Water quality — Examination and determination of colour
Cancels and replaces the first edition (1985). Specifies three methods for the examination of colour: a method for the examination of apparent colour by visually observing a water sample in a bottle; a method for the determination of the true colour of a water sample using optical apparatus; a method for the determination of the colour by visual comparison with hexachloroplatinate standard…
Mechanical vibration — Symbols for balancing machines and associated instrumentation
Cancels and replaces the first edition (1982). Establishes symbols for use on balancing machines including instrumentation. They are intended to complement those already standardized in documents such as ISO 7000. The primary purpose of the symbols is to explain the functions and uses of the indicators and controls which are an integral part of a balancing machine.
