Conclusions
(1) Peroxides in oils increase at a uniform rate when the oils are irradiated with light from a constant source, such as CX lamps.
(2) An oil which has been protected by a sextant green filter and which has already developed a certain amount of peroxides will, when exposed simultaneously to light of CX lamps with a fresh sample of the same oil, continue to develop peroxides, and at the same rate as that of the fresh oil.
(3) The induction period of an oil which has been protected by a sextant green filter is unaffected by the peroxides which were developed during protection and is equal to that of a fresh sample of the same oil.
(4) The development of rancidity in oils that have been protected by a sextant green filter proceeds independently of the peroxides that may be already formed.
(5) Peroxides which develop under a sextant green filter do not increase the susceptibility of the oil to become rancid.
