How are Washing Machines Tested in Laboratories?

 All washing machines undergo laboratory testing to measure wash performance, noise levels, and power and water consumption. It draws attention to products with desirable qualities while assisting producers and merchants in creating a more appealing product line for consumers.

The tests emphasize the Washing Machines' capacity for washing, rinsing, and spinning dry clothes and their usability and energy efficiency. What else? Let’s learn more about washing machine performance tests and how it’s done in our laboratories!

What are Washing Machine Test Laboratories?

The washing machine test labs emphasize the tests for their capacity for washing, rinsing, and spinning dry clothes and their usability and energy efficiency. Therefore, the key features of spin cycle efficiency, rinsing efficiency, cleaning efficiency, water & energy consumption, customer-friendliness, safety & design quality are covered in the laboratory testing of washing machines, which are based on standards for washing machine testing.

Every performance test is run against an industry-reference machine that regularly performs well. Therefore, evaluating and rating the washing machine's performance are based on variations from the reference machine.

What Parameters Are Tested in Washing Machine Test Laboratories?

To test whether the washing machines are functioning well, various testing procedures for washing machines are carried out in the Washing machine test lab. These include:

Washing Machine Features

The laboratory first reviews the washing machine's instruction manual and notes its features and other relevant details. A general evaluation of the washing machine's quality and design is also carried out during the test. User safety is also included in the testing.

Cleaning Efficiency

The washing machine's capacity to completely wash whites and cotton is tested at a particular temperature. Standardized stains on white cotton fabrics are cleaned several times.

Cotton padding fabrics are placed inside the washing machine to the maximum capacity allowed. After washing and drying, the cleanliness is assessed using equipment, and the outcomes of the standard reference machine are compared.

Rinsing Efficiency

The fabrics are spun after being rinsed, and the rinse water is analyzed for detergent residues. Finally, the standard reference machine's value is contrasted with the detergent residues' level.

Spin Performance

The value of the standard reference machine is used to compare the moisture content. Weighing the clothing before and after washing allows for determining its moisture level after spin-drying.

Energy Consumption

The total energy used for a whole washing cycle (washing, rinsing, and spin-drying) is tracked and calibrated by the machine's kilogram capacity. Finally, a comparison is made between energy usage and the value of the standard reference machine.

Water Consumption

The total amount of water used throughout a full washing cycle (washing, rinsing, and spin-drying) is tracked and calibrated to the machine's kilogram. Finally, a comparison is made between water usage and the efficiency of the standard reference machine.

Water Temperature

Throughout the primary washing activity, a continuous thermometer measures the water temperature and the temperature of the fabrics. Therefore, throughout the direct washing program, the temperature should not change noticeably from the chosen program.

Noise and Ease of Use

The highest noise level is measured one meter from the machine and one meter above the ground during the spin cycle. These devices often have noise levels equivalent to a normal conversation (about 65dB). It's not a precise noise measurement—your home's acoustics will affect how loud a machine sounds in use—but it's a fair comparative one. 

The Bottom Line

Following the testing completion, the machine is graded according to the standards listed in the criteria specified earlier. Finally, the device performance is compared against the manufacturer's promises in test labs, along with the functionality of each feature.

Our washing machine performance laboratory provides all the test circumstances, the testing environment, and the testing infrastructure. In addition, the test room can be used to evaluate various washing machine characteristics in line with the following standards for washing machine testing:

●      IEC 60456: Approaches for Measuring the Performance of Clothes Washing Machines for Home Use.

●      IEC 60335-2-7: Washing machine safety requirements for home and similar electrical equipment.

Environmental Test Chamber: What is it & How Does it Work?

Have you ever purchased a product that, after only a few weeks or perhaps your first usage, proved to be faulty? It can be due to some items being exposed to environmental factors like temperature, humidity, and vibrations that weren't anticipated or otherwise considered when they were being developed.   That's why the various environmental conditions to which the product will be exposed must be considered throughout the development and design process. But how to test them?   That’s where the environmental control chamber steps in. Environmental test chambers have been used for years for simulated environmental tests in industrial, automotive, electronics, aerospace, artificial intelligence, and medical research industries.   Today, we’ll explain an environmental simulation chamber and how it works. What is an Environmental Test Chamber? Before understanding the environmental test chambers, it is important to understand the environmental test and its applicatio...
