4.2 In order to ensure safety in handling, the test method requires that volatile fuels be transferred from the sample
container to the funnel without pouring. Fuels having a verified flash point greater than 38°C (refer to Test Method D 56 or Test Methods D 93 or D 3828) may be transferred by pouring the sample from the sample container directly into the funnel. Bonding the sample container to the funnel is required. (Warning—Volatile fuels such as JP-4 and Jet B or mixtures
having flash points below 38°C have been ignited by electrostatic discharges when poured through membrane filters.)
