Product performance can positively or negatively affect customer satisfaction; products must be fit for use, claims used in advertising must correspond to product characteristics (link to claims), and a market leader must deliver a high level of performance to avoid disappointing consumers.

Performance evaluation is one of the Mérieux NutriSciences laboratories’ main strengths. Years of experience and our sophisticated range of instruments, some of which have been purpose-designed, enable us to support our customers in extensive and exhaustive performance evaluation tests for a wide range of products, including plastics, detergents (link to detergents), absorbing aids (link to physico-mechanical properties), accelerated aging (link to accelerated aging), and exposure to light and weathering (link). We can test the following aspects using standard methods and via tailor-made studies (link to R&D):

• Chemicals (link) 
• Physico-mechanical and rheological properties (link)
• Color fastness (link to colorimetry)
• Sensory analysis and consumer research (link)
