18、E 2Failure to cool the container completely may result in a falseresult.5.4.2 Scratch Procedure:5.4.2.1 Using Method AWith a tungsten carbide scribe,scratch once around the inside knuckle of the article. Thenscratch an “X” across the entire inside bottom surface of thearticle. All scratches are to b

Ensure that all sharp corners,dimples, indentations are abraded. A new
20、piece of emerypaper/cloth is to be used for every piece tested.5.4.3 After using either method A or B, fill each article withwater at the same room temperature as the glass. Wait fifteenminutes, then empty the water and examine each piece forfractures.5.5 ReportReport the number of fractures, if any
