NF

The NF standard refers to a set of French standards (Normes Françaises) that define technical specifications and guidelines for various industries and materials. These standards are developed by the Association Française de Normalisation (AFNOR), which is the national organization responsible for standardization in France. NF standards cover a broad range of topics, including construction, materials, environmental concerns, and specific product testing methods.
Test Materials: The NF standard specifies materials like plastic films or packaging for testing, ensuring they meet specific conditions to guarantee accurate results.
Test Process: The process involves sample preparation followed by applying controlled stress or force using calibrated equipment to evaluate key properties.
Test Result Interpretation: Results are compared against benchmarks in the NF standard, focusing on whether the material meets required performance criteria like strength or resistance.
