Expertise and characterization of materials, analysis of their properties

In order to help manufacturers ensure the quality of their products and anticipate the risk of failures, LNE characterizes the materials they use by analyzing their chemical, physical, mechanical and structural properties, which makes it possible, among other things, to optimize their performance

Characterization services offered

The chemical, physical, mechanical and structural characteristics of the materials used in the manufacture of a product (finished product, semi-finished product, component part of the final product, etc.) have a decisive influence on its final performance and lifespan.

The characterization of materials is carried out by analyzing their properties through chemical, physical, and mechanical tests. This analysis allows manufacturers to optimize the performance of their materials and control the risk of failure, both during the design and during the use of the final product. It also makes it possible to adapt and improve them to meet technological or environmental requirements, but also to be able to choose them wisely according to their use.

In your sectors of activity where quality requirements are high (medical, aeronautics-defense, energy-nuclear, construction products, packaging, cosmetics, etc.), you need to ensure that :

Your materials have the expected characteristics
Their properties are reliable over time and in various environments
the risk of failures is controlled.

LNE characterizes your material samples by offering you the following services:

Material analysis to evaluate:
- His performance
- Its evolution over time
- Its compatibility with the end use of the product
- Causes of a malfunction of the final product
Evaluation of the material's conformity with regard to:
- Standards in force
- A customer specification
- New standards for solutions for the reuse of materials and the reincorporation of recycled and bio-sourced materials

Expertise deployed according to the need

Our know-how is based on our ability to formulate hypotheses for the qualification of your material in relation to the expected analysis objective: performance improvement, failure study, etc.

For metals-alloys, polymers, ceramics, or multi-materials, we can more specifically:

Propose the most suitable tests with regard to the use of your product or material
Interpret the analyses resulting from the characterizations and to explain the performance of the product
Suggest ways to improve the performance of your product
Search for and identify trace material using specific test methods
Travel to the site to study the design and manufacturing lines and their global environment in order to adapt the best analysis solutions.

Conformity assessment

Our experience in standards and regulations also allows us to assess the conformity of your products and to support you in their evolution or in the development of your new materials.
