Quality Standards


Products tested to British and European standards provide greater durability, longer warranty periods, peace of mind and evidence of professional specification.

Under the standard each product is tested and classified accordingly to show its compliance. The identification of a numeric code is visible on the individual product.

Each digit represents a category and how it is measured against the standard to which it was tested.
