SCHEDULE 1 CLASSIFICATION OF SUBSTANCES AND PREPARATIONS DANGEROUS FOR SUPPLY

PART III METHODS FOR THE DETERMINATION OF FLASH POINT
1 For the purpose of classifying a substance or preparation dangerous for supply or carriage in accordance with Part I of this Schedule or Part I of Schedule 3, the flash point shall be determined—
(a) by one of the equilibrium methods referred to in paragraph 3; or
(b) by one of the non-equilibrium methods referred to in paragraph 4, except that when the flash point so determined falls within one of the following ranges, namely:—
(i) −2°C to + 2°C,
(ii) 19°C to 23°C, or
(iii) 53°C to 57°C,
that flash point shall be confirmed by one of the equilibrium methods referred to in paragraph 3 using like apparatus.
