The significance of withdrawing a standard is to identify that the method is no longer being maintained and updated by a subcommittee.
The test results, when properly related to vapor pressure and density of the product, can be used to indicate the presence of butane and heavier components in propane-type LP-gas, and pentane and heavier components in propane-butane and butane-type fuels.
