These techniques describe standardized approaches to well-known, widely used laboratory practices of sample preparation utilizing acid digestions and borate salt fusions. This practice is applicable to fresh and equilibrium FCC catalysts and exchanged zeolite materials.<\/p>\n<p id=\"s00003\">1.2 The values stated in inch-pound units are to be regarded as standard.
