Performance Requirements4.1 Annealing:4.1.1 Transparent GlassContainers examined under po-larized light in accordance
7、with Test Methods C 148 shall, afterannealing, show no greater than real temper number 4. Thisperformance requirement will also apply to containers that arefurther processed (such as ceramic enamel decorations), fol-lowing the original manufacture, by reheating the containerabove the strain point an

Containers tested in accordance with theScratch Test shall show no fractures.4.1.2 Non-transparent GlassIf glass condition (color,decoration, etc.) prohibits sufficient light transmission f

Test Methods5.1 ScopeThis Scratch Test Method is designed to
12、ensurethat residual stress is reduced to a commercially acceptablelevel in annealed soda-lime-silicate glass containers that areintended for use as candle containers. It provides an alternativemethod to Test Methods C 148. Two methods of performingthe Scratch Test are covered:1This specification is

16、e and fifty-grit emerypaper/cloth.5.2 Significance and UseThis test method can be used inthe quality control of soda-lime-silicate glass candle contain-ers, where the degree of annealing must be verified to ensurequality products. This procedure can be used where glasscannot be read by polariscope (
17、color, decoration, etc.) or as analternative method for transparent glass containers.5.3 SamplingMethods of sampling for a group of contain-ers of a given type are given in Practice C 224 for annealing.5.4 Test Procedure:5.4.1 Allow the ware to cool evenly through the entirethickness of the containe
18、r to room temperature before usingeither Method A or B.NOTE 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 i
19、nside bottom surface of thearticle. All scratches are to be made using sufficient pressure topenetrate the surface of the glass.5.4.2.2 Using Method BWith fifty-grit emery paper/cloth,abrade the inside surface of each article using sufficient force topenetrate the surface of the glass. Ensure that a
20、ll sharp corners,dimples, indentations are abraded. A new 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 for
21、fractures.5.5 ReportReport the number of fractures, if any for eachtest.5.6 Precision and BiasNo information is presented abouteither the precision or bias of the scratch test method since thetest result (fracture versus no fracture) is nonquantitative.6.
