--- This is the second revision: Method for determination of chemical corrosion resistance of glazed surfaces of household ceramics1 ScopeThis document describes the method and method for the determination of the chemical corrosion resistance of glazed ceramics for daily use characterized by color difference ΔEab* at room temperature and under heating conditions: performance evaluation: This document is applicable to the determination of the chemical corrosion resistance of glazed surfaces of household ceramics:2 Normative referencesThe contents of the following documents constitute the essential provisions of this document through normative references in the text: Among them, dated references For documents, only the version corresponding to the date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to this document: GB/T 3979 Measurement method of object color GB/T 5000 Terminology of Ceramics for Daily Use GB/T 5698 Color Terminology GB/T 6682 Analytical laboratory water specifications and test methods GB/T 9086 Standard whiteboard for colorimetric and photometric measurement3 Terms and DefinitionsThe terms and definitions defined in GB/T 5000 and GB/T 5698 apply to this document: 3:1 Chromatic differencecolordifference Quantitative expression of color perception differences: Expressed by ΔE: [Source: GB/T 5698-2001, 4:62]4 principlesUnder different temperature conditions, after a certain period of time, the glazed surface of daily-use ceramic samples will be corroded by chemical test solution, and the color will change to varying degrees: The color difference of the glaze surface before and after the corrosion of the sample is measured by an instrument; and the color difference within the corrosion cycle is measured according to the internationally recognized color difference judgment criteria: The maximum value of the glaze color difference ΔEab(max) is evaluated to obtain the grade of the chemical corrosion resistance of the glazed surface of the test sample:5 Reagents or MaterialsUnless otherwise specified, use only analytical grade reagents and above: 5:1 Water, GB/T 6682, Class III: 5:2 Citric acid solution, 100g/L: 5:3 Hydrochloric acid solution, 20% (mass fraction): ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 5003-2023_English be delivered?Answer: Upon your order, we will start to translate GB/T 5003-2023_English as soon as possible, and keep you informed of the progress.
