But color also plays a part, undoubtedly in terms of quality if not safety. You wouldn't want to buy a pushchair with a covering that faded quickly, would you?

The test that measures a fabric's capacity to maintain its color is called the light fastness test. As always, it starts with a sample.

The test measures the resistance of the color (its ability not to fade) during exposure to a source of natural or artificial light over a fixed time interval. The fabric samples are inserted in a special machine.

The samples inserted in the machines are subject to strong and continuous light over a fixed time.

At the end of the test the team assesses the color of the fabric, and determines if its pigmentation is "stable”, that is resistant to prolonged light exposure. Of course, the parameters applied on these product quality tests are based on average usage. To ensure that the product maintains its quality over time you should limit extended exposure to sunlight, such as on the beach in summer, particularly during the hottest part of the day.
