ENVIRONMENTAL TEST FACILITIES

Environmental test facilities

CSMST is equipped with state-of-the-art environmental test facility, backed by an experienced research group. Environmental tests are an integral part of the development and certification process of components for Aerospace products.

Need for Environmental Conditioning / Testing
Environmental simulation is used to determine a product's ability to perform during or after exposure to a specific environment. These tests are often used to prove a product's integrity, verify manufacturer's claims regarding operational limits, determine realistic warranty terms, and prepare procedures on proper and safe operation. The mechanical, thermal and electrical properties of components change during environmental exposure. To determine the magnitude of these changes, the usual procedure is to expose the materials to a moist environment for a sufficient length of time until the moisture level inside the material reaches the required value. The material is then brought back to the natural environment and tested to quantify the changes in properties resulting from moisture absorption, which unfortunately lasts for months or years. In several circumstances long conditioning times are unacceptable. Hence, in order to reduce the time required to saturate the material with moisture, accelerated environmental conditioning tests (temperature, relative humidity and altitude) are carried out. Therefore, a variety of environments may be encountered by a product in its expected lifetime.

The Integrated Environmental Test Facility at CSMST carries out its testing activities as per ISO 9001:2008 quality procedures.
