"Intumescent Coating Fire Protection

Intumescent fire protection is developing so fast that new products offering greater performance with lower thicknesses are appearing in the market with increasing frequency. This trend of ‘using less to do more’ can raise questions amongst designers, specifiers, regulators and enforcers about the ability of products to deliver.

Additionally, within the next 2 years, intumescent fire protection will have to be CE marked under the Construction Products Directive to be placed on the European market. Whilst CE marking is not mandatory within the UK, many manufacturers of work at a European level. CE marking as proof of conformity, involving third party certification of the product, is viewed by the industry as the most effective way to demonstrate performance and reliability."

Wie wird hier "enforcer" am besten übersetzt?

Ganz herzlichen Dank im Voraus!
