This Standard covers the following two direct methods, which vary only in the time allowed for the gas to desorb from the intact sample prior to final crushing:(a) The slow desorption method.(b) The fast desorption method.The Standard is confined to the direct method using lump or core samples.Desorption limitations to the method are specified in Appendix A.This Standard does not include the gas content determination using cuttings from drilling and interpretation of the results do not fall within the scope of this document.
