This Standard is drafted in accordance with the rules provided by GB/T 1.1-2009. This Standard is an revised edition of QB/T 1520-1992 Electric Dishwashers for Household Use. Compared with QB/T 1520-1992, the main differences are as follows. -- Delete the terms and definitions of full-automatic dishwasher, semi-automatic dishwasher, non-automatic dishwasher, spraying dishwasher, scroll dishwasher, detergent and rinse agent;
-- Add the terms and definitions of cleaning index, drying index, energy efficiency index, left-on mode, off-mode, annual energy consumption, eliminating bacterial rate and antibacterial rate;
-- Add the provisions of 5.9 ?€?Mean Time Between Failure?€?, 5.10 ?€?Left-on power?€?, 5.11 ?€?Off power?€?, 5.12 ?€?Eliminating bacterial rate?€?, and 5.13 ?€?Allowable deviation of indicated value?€?;
-- Add the test methods of 6.3.5 ?€?Left-on power?€?, 6.3.6 ?€?Off power?€?, 6.3.10 ?€?Mean Time Between Failure?€?, 6.3.14 ?€?Eliminating bacterial rate and antibacterial rate?€?; -- Revise the original Annex A ?€?Preparation of dishware pollutants and pollution methods?€? into ?€?Grading and classification of key performance indexes?€?;
-- Revise the original Annex B ?€?Standard dishware?€? to ?€?Test method for eliminating bacterial?€?;
-- Revise Annex C ?€?Detergent and rinse agent?€? to ?€?Test failure examples in Mean Time Between Failure?€?;
-- Delete Annex D;
-- Change the compiling structure of this Standard.
