• Cleaning power test according to types of pollution ※ Cleaning power test based on fat-soluble pollution
  • Test time: October, 2022
  • Testing lab: LG lab in-house test
  • Target: Commercial liquid detergent and Mineral Washer
  • Condition: Comparison of washing performance between LG Electronics' 24kg drum washing machine using commercial detergent and Mineral Glass, based on a load of 3kg. For lipophilic pollution, EMPA 106 (Carbon Black), EMPA 112 (Cocoa), and EMPA 118 (Sebum) were used to compare washing performance.
  • Test method:
    • - The washing performance of each detergent was compared according to the international standard IEC 60456, using EMPA 108 and JIS C 9606 pollution samples.
    • - A spectrophotometer (Minolta, CR-400) with a D65 light source measured the surface reflectance of test samples at 520nm.
    • - Results were analyzed using either the Tristimulus Y value or by calculating the average whiteness value.
    • - Cleaning power (%) calculation:
    • 1. Whiteness = 100 -√((100 -L)² + a² + b²)
    • 2. Cleaning power (%) = {(Whiteness after washing - Whiteness before washing) ÷ (Whiteness of original fabric - Whiteness before washing)} x 100
  • Test result: In the EMPA 108 set, the TristimulusY values after washing for lipophilic samples EMPA 106, 112, and 118 were similar for both commercial detergents and Mineral Glass, at 183.9 and 183.3, respectively.

  • Test result: In the EMPA 108 set, Mineral Glass outperformed commercial detergents for hydrophilic samples EMPA 111 and EMPA 122, with Tristimulus Y values of 100.3 versus 92.7.

• 1) LG ThinQ™
  • To use ThinQ features, you need to install the 'LG ThinQ' app from the Google Play Store or Apple App Store on your smartphone and connect to Wi-Fi. LG ThinQ™ app available on compatible Android 9.0 or higher, iOS 16.0 or higher smartphones. Phone and Home Wi-Fi Data connection and product registration with LG ThinQ™ required.
  • LG ThinQ™ functions may vary depending on the product and country.
• 2) AI Saving Mode
  • The AI saving mode can be adjusted in two stages (up to 1% for stage 1 and up to 5% for stage 2), and the savings rate varies depending on the product's energy rating and specifications.
  • The AI savings rate for each stage may vary depending on actual usage conditions.
  • The specific test details for the savings rate are as follows
    1. Test Model: GBBW322CEV
    2. Condition: Freezer at -18°C, Refrigerator at 3°C, No Load
    3. Installation Conditions: Room temperature at 25°C, humidity at 55%
    4. Test Method: 8-hour opening, 16-hour no opening Total opening times during the opening hours: Refrigerator 28 times, Freezer 6 times Energy results for each AI saving mode stage over 3 days are converted to 24-hour energy consumption and compared.
    5. When using the AI saving mode, the frost removal cycle and compressor speed may be adjusted according to the surrounding environment. Applying stage 2 may result in an increase in internal temperature of the freezer and refrigerator.
    6. The test results have been verified by TÜV Rheinland Inc. using their specified testing method, but they may vary depending on the actual usage environment.
    7. The AI saving mode is only supported through the LG ThinQ app, and LG ThinQ may have some limitations in terms of supported environments and usage methods.
