Moisture Resistance Evaluation of Moisture-Proof Sealant for Outdoor Electrical Equipment-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Moisture Resistance Evaluation of Moisture-Proof Sealant for Outdoor Electrical Equipment Moisture-proof sealants are increasingly used to protect outdoor electrical equipment from moisture ingress. However, standardized methods to quantify their moisture resistance are lacking. This report proposes a test method based on ASTM E96 to evaluate the moisture barrier properties of moisture-proof sealants. Moisture poses a significant threat to the safe operation of outdoor electrical equipment. It can lead to electrical shorts, metal corrosion, and equipment failure. Moisture-proof sealants are applied to seal gaps and prevent moisture ingress. While these sealants are becoming more common, there is a lack of standardized methods to assess their effectiveness. The proposed test measures the water vapor transmission rate (WVTR) of the sealant sample. WVTR indicates the rate at which water vapor permeates through a material. A lower WVTR signifies a higher moisture barrier property. By measuring the WVTR of a sealant sample, this test provides an objective evaluation of its ability to resist moisture ingress. The test method follows the cup method outlined in ASTM E96. This gravimetric method measures the mass change of a sealed cup containing the sealant sample over time. The cup is placed in a controlled environment with a high relative humidity on one side and a 1

The cup's weight is periodically measured, and the WVTR is calculated based on the weight change and the test duration. The Labthink C360H Water Vapor Transmission Rate Test System is used in this test method. This instrument provides a controlled environment for the test cup and automates the measurement process. It ensures consistent testing conditions and accurate data collection. This test method provides a standardized...
