EN Numbers: Knowing The Standard for Cleaning Products

With the increase of cleaning activity during and since the Covid-19 pandemic, there has been greater discussion around improving cleaning standards, knowing your EN numbers, and the difference between specific cleaning products.

You may have even read the back label of a spray or liquid and seen EN:1276 or EN:14476, but what do they mean to you and your business? The abbreviation EN stands for European Standard, which is a series of quality and safety criteria that if a product makes a claim, it has to have passed. The numbers correspond to a specific test, and in most cases, for disinfectants, bleaches and sanitisers they relate to a series of microbial suspension methods.

Here, we are going to explain what the tests are and what each number refers too, to help you make a more qualified decision when purchasing products.
