of the cloud point of petroleum products and biodiesel
fuels that are transparent in layers 40 mm in thickness, by an
automatic instrument using an optical device.
1.2 This test method covers the range of temperatures
from −60 to +49°C with temperature resolution of 0.1°C,
however, the range of temperatures included in the 1997
interlaboratory cooperative test program only covered the
temperature range of –56 to +34°C.
1.3 The values stated in SI units are to be regarded as
