[Video] Engineered to Perfection: Inside the Intense Testing Regimen of Samsung Home Appliances

Reliability is paramount in home appliances. Samsung has stayed true to this principle by putting its products through comprehensive testing to ensure that they can effectively handle the various demands of daily life.

Samsung Newsroom took an inside look at the thorough quality tests that set Samsung home appliances apart.

Refrigerators: Durability and Temperature Consistency Throughout

The refrigerator is the most frequently used appliance in the kitchen. To ensure Samsung refrigerators operate in the most demanding conditions, the Door Slam Test simulates the act of opening and closing fridge doors tens of thousands of times depending on the model. During the process, engineers assess the hinges for sagging, listen for unusual noises and examine whether the doors continue to function smoothly under stress.

Tests are also carried out to evaluate proper performance throughout the four seasons. The Temperature Maintenance Test pushes refrigerators to their limits by replicating different seasonal weather conditions — from freezing winters to sweltering summer heat waves of over 40 degrees Celsius — making sure optimal cooling performance is maintained in challenging external environments.

Preserving the freshness of food ingredients, meanwhile, relies on maintaining a consistent internal temperature. Using thermocouples placed throughout the refrigerators and freezers to be tested, the Compartment Test (Notch Test) alters notch settings and simulates variations in humidity and temperature to check whether each product’s compartments and shelves are cooled evenly.

For refrigerator models equipped with automatic ice makers, the Ice-making Performance Test checks ice production capabilities and the quality of ice by varying water pressure, temperature and notch placement.

Washing Machines: Ready To Thrive in Harsh Winters and Wet Environments

Washing machines are often installed in areas with lower temperatures or exposure to water, such as balconies or bathrooms. To make sure its products perform reliably under these conditions, Samsung conducts rigorous stress tests.

The Freezing Test evaluates the durability of Samsung washing machines in the winter by repeatedly exposing the appliances to temperatures as low as those in the Arctic and as high as those in scorching summers. Additionally, engineers carry out a Water Leakage Test to assess the washing machines’ resistance to leaks. They fill the drums with water, place the machines at tilted angles and monitor them for leaks over a period of 24 hours or more under varying humidity levels and different temperatures.

The Water Protection Test, on the other hand, checks whether the washing machines work properly in wet environments. High-pressure rotating nozzles spray water onto the appliances for extended periods of time, with engineers closely monitoring for water infiltration into electrical components or condensation issues caused by humidity.

Kitchen Appliances: Designed With Product Lifespans in Mind

The lifespans of Samsung electric cooktops under real-world conditions can be estimated through the Durability Test. In this simulation, engineers test the durability of dozens of cooktops over several months by repeatedly heating and cooling standard containers on them while the containers are automatically refilled with water.

Samsung dishwashers undergo the Basket In and Out Test to be checked for any defects in their rollers.  Engineers purposefully overload the dishwashers’ baskets beyond standard capacity and slide them in and out tens of thousands of times to ensure the quality of their rollers, rails and nozzles.

Every Samsung home appliance is built with one ultimate goal — to give users peace of mind, even in unexpected moments. Samsung will continue strengthening quality control and inspection across its product lines in constant pursuit of unprecedented levels of safety and durability.
