1、Designation: C 735 04Standard Test Method forAcid Resistance of Ceramic Decorations on Returnable Beerand Beverage Glass Containers1This standard is issued under the fixed designation C 735; the number immediately following the designation indicates the year oforiginal adoption or, in the case of re

2、vision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers qualitative determination of theacid resistance of ceramic decorations on

3、 returnable beer andbeverage containers, to assure the necessary durability of thedecoration.1.2 This test provides an indication of performance whenand if the decoration is to be exposed to the acid solutions usedin reclaiming bottles, and it also covers those instances wherethe beverages themselve

4、s have acidic properties.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations pri

5、or to use.2. Referenced Documents2.1 ASTM Standards:2C 224 Practice for Sampling Glass Containers3. Summary of Test Method3.1 This test method is a qualitative method which deter-mines by visual inspection the degree of attack of a nominal10 % hydrochloric acid solution on the ceramic decoration.4.

6、Significance and Use4.1 This test method evaluates the quality and serviceabilityof ceramic decorations on returnable beer and beverage con-tainers.4.2 This test method is also suitable for specification accep-tance. Its significance is that bottles with good acid resistancecoatings have longer serv

7、ice life.5. Reagent5.1 Hydrochloric Acid (27 + 73)Dilute 27 volumes ofconcentrated hydrochloric acid (HCl, sp gr 1.19) with 73volumes of distilled water. This will produce nominal 11.5weight % HCl. The volume of the solution may be varied asneeded.6. Test Specimen6.1 The decorated ware should be rep

8、resentative of the lot,or run, and should be taken in accordance with the principlesstated in Practice C 224.7. Procedure7.1 Pour the HCl (27 + 73) into a beaker large enough toaccept all of the test specimen and the reference sample. Keepthis solution at room temperature (25 6 5C).7.2 Place the tes

9、t specimen into the HCl so that approxi-mately one half of the label is immersed, and cover the beaker.7.3 Remove the specimen from the HCl after 20 min. Rinsewith water and dry.7.4 Record the temperature of the HCl at both the beginningand the end of the test period.7.5 Retain a duplicate piece of

10、ware with each decorationunder test, without exposure to HCl as an aid in judging thedegree of chemical attack on the specimens under test.8. Interpretation of Results8.1 Judge the degree of the HCl attack on the decoratedsurface by visually comparing the exposed specimen to thenonexposed specimen,

11、if such is available.8.2 Grade the decoration on the test specimen according toone of the following classes:Grade 1No attack apparent.Grade 2Appearance of iridescence or visible stain on theexposed surface when viewed at a 45 angle but not apparentat angles less than 30.Grade 3A definite stain which

12、 does not blur reflectedimages and is visible at angles less than 30.Grade 4Definite stain with a gross color change orstrongly iridescent surface visible at angles less than 30.Grade 5Surface dull or matte with chalking possible.1This test method is under the jurisdiction of ASTM Committee C14 on G
