Refrigerator Model:HBC-70/200（India） MAINTENANCE SERVICE AND TROUBLE SHOOTING (13) Electricity consumption; (14) noise and vibration; (15) electroplated parts; (16) painting cover; (17) protection of anti-electric shock; (18) cables; (19) door opening force; (20) freezing ability; (21) rising up speed of temperature with load. Type tests include items (1), (2), (8), (9), (10), (13), (17), (18), (20), (21) and the followings: (22) total effective volume; (23) ice producing ability; (24) frost melting performance; (25) heat insulation performance and anti dew; (26) gas tightness of door seal; (27) duration of door bar and handle; (28) strength of supporting bracket and similar parts; (29) internal refrigerator material and smell; (30) firmness of refrigerator and transportation test. 12.8.2 Test method and instrument 12.8.2.1 Sealing performance test of refrigeration system In this test, refrigerator is put to positive pressure room, temperature is 16-32℃. Leakage inspection instrument is set to 0.5g of yearly leakage, check every position of refrigeration system. Leakage at any point shall not greater than 0.5g. Leakage inspection instrument normally used includes H-25 of American GE product and Halogen instrument HLD4000 made by a German company. 12.8.2.2 Insulation resistor This test is to check the insulation performance of refrigerator. The resistance is measured with a voltage of 500V DC added to live parts and accessible metal parts. The resistance must be not less than 2 million ohm. ５２ PDF created with pdfFactory trial version www.pdffactory.com

12.8.2.1 Sealing performance test of refrigeration system
In this test, refrigerator is put to positive pressure room, temperature is
16-32
℃
. Leakage inspection instrument is set to 0.5g of yearly leakage,
check every position of refrigeration system. Leakage at any point shall not
greater than 0.5g. Leakage inspection instrument normally used includes
H-25 of American GE product and Halogen instrument HLD4000 made by a
German company.
12.8.2.2 Insulation resistor
This test is to check the insulation performance of refrigerator. The
resistance is measured with a voltage of 500V DC added to live parts and
accessible metal parts. The resistance must be not less than 2 million ohm.
