British Standard BS ISO

With reliable instrumentation available, a stress relaxation procedure was eventually standardized as ISO 289-467. The normal Mooney apparatus has, in addition, to be capable of being stopped within 0.1 s, resetting zero torque for a static rotor and recording the torque every 0.2 s. The decay of torque with time is plotted on a log-log scale and the slope of the resulting line taken as the Mooney stress relaxation rate. The British standard, BS ISO 289-4 is identical and ASTM D164640 has the same procedure. 

British Standard BS ISO 3864 Graphical Symbols, Safety Colours and Safety Signs is concerned with a system for giving safety information which does not, in general, require the use of words and covers safety signs, including fire safety signs.
