1.1This test method covers a procedure for determination of the relative crystallinity of zeolite Beta containing samples using selected peaks from the X-ray diffraction (XRD) pattern of the zeolite.
1.2The test method provides a number that is the ratio of intensity of a portion of the XRD pattern of the sample zeolite Beta to intensity of the corresponding portion of the pattern of a reference zeolite Beta. The intensity ratio, expressed as a percentage, is then labeled percent XRD relative crystallinity of zeolite Beta. This type of comparison is commonly used in zeolite technology and is often referred to as percent crystallinity.
1.3This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
