This document specifies a method for determination of carbon monoxide (CO) in the vapour phase of Heated Tobacco Products (HTP) using puffing regimes defined for this category of products. The part one will address the CO determination of electrically Heated Tobacco Product (eHTP).
Propylene oxide for industrial use — Part 1: Determination of purity and trace impurities — Gas chro...
This document specifies a test method for the determination of propylene oxide and trace impurity in industrial propylene oxide by capillary gas chromatography. This document is suitable for the determination of propylene oxide with a purity of no less than 95% (mass fraction) and of trace impurity in the concentration range of 0.0001%~1.000% (mass fraction).
Rubber, vulcanized or thermoplastic — Determination of the effect of liquids
This document describes methods of evaluating the resistance of vulcanized and thermoplastic rubbers to the action of liquids by measurement of properties of the rubbers before and after immersion in test liquids. The liquids concerned include current service liquids, such as petroleum derivatives, organic solvents and chemical reagents, as well as reference test liquids.
