NORME FRANCAISE
The NF mark is a collective certification mark. It guarantees the quality and safety of the products and services certified. The NF mark guarantees compliance not only with current standards, but also with additional quality criteria that meet consumers' needs.

90% of the French population knows the NF mark. For nearly 60 years it has adorned consumer products such as electric plugs, refrigerators, taps, and so on. More recently, service providers such as tourist offices and passenger transport companies have been highlighting the quality of their services through the NF Service mark.
