1.1 This test method uses inductively coupled plasma mass spectrometry (ICP-MS) to determine multiple trace elements in cannabis and cannabis-related matrices following sample preparation using microwave-assisted acid digestion. This test method is applicable to the quantification of trace levels...
5.1 The objective of this practice is to provide guidelines for the preparation of stable, representative, oxidized, relatively unpolluted, aquatic natural-matrix bed-sediment reference test samples. When prepared as described, such test samples should be useful for collaborative methods testing,...
This document specifies a method for the determination of the gross calorific value of a solid mineral fuel at constant volume and at the reference temperature of 25 °C in a combustion vessel calorimeter calibrated by combustion of certified benzoic acid. The result obtained is the...
4.1 This document provides guidance for the implementation of procedures for the preparation, testing, and documentation of an in-house reference material (hereafter called an iRM) to be used for a number of purposes, enumerated in the following document, associated with development, validation,...

General Application Coverage This inspection code covers the in-service inspection, repair, alteration, and rerating activities for pressure vessels and the pressure-relieving devices protecting these vessels. This inspection code applies to all hydrocarbon and chemical process vessels that have...
This International Standard specifies a method for the determination of the gross calorific value of a solid mineral fuel at constant volume and at the reference temperature 25 ºC in a bomb calorimeter calibrated by combustion of certified benzoic acid. The result obtained is the...
This International Standard provides guidelines to test for bias over a wide range of mass measurement techniques, to estimate the precision for each technique and to calculate the precision for wet mass when estimated by applying one of those techniques. The guidelines are based on the application...

PREFACE Exposures to over-the-counter products are frequent in pregnant women. Perhaps this is a paradoxical response to the decreased use of prescribed medications during pregnancy for fear of teratogenicity. For many women, natural health products such as herbal medicines or supplements may seem...
