(c) shall have an ultra-violet extinction (otherwise called absorbance) at 290 millimicrons not greater than 1.0 for a 1 centimetre layer of a solution in iso-octane containing 1 gram per litre, that is to say, E ⁢ 0.1% 1 cm. shall not be greater than 1.0 where E=log10 (Io/I) and Io and I are the intensities of the incident radiation and of the transmitted radiation respectively; and
