It is hoped to publish further lists of established ignitionapos;temperatures from time to time@ as the results of tests made in several countries become available.A first draft was discussed at a meeting held in Ottawa in 1966@ as a result of which the final draft was submitted to the National Committees for approval under the Six Months?? Rule in September 1967.The following countries voted explicitly in favour of publication of this Supplement :AustraliaBelgiumCanada CzechoslovakiaDenmarkFinlandFranceGermanyIranIsraelItalyJapanNetherlandsNorwayPolandRomaniaSouth AfricaSwedenSwitzerlandTurkeyUnion of Soviet Socialist RepublicsUnited KingdomUnited States of AmericaYugoslavia
