Materials Resistance to Positive and Negative Pressure Conditions
In numerous fields, such as the rail, aeronautics and construction sectors, materials and particularly windows may be subjected to significant positive and negative pressure waves. It is essential that such equipment and the materials they are made from be tested to ensure that they are fit for purpose. You want to consult or share the […]

Monitoring in-service lubricant wear
On rolling stock, many lubricants are used to keep parts working smoothly. These greases play a major role in extending equipment life cycles and can have vital safety functions by preventing wear and rust in contact surfaces. Lubricants are instrumental in maintaining air and water-tightness and in evacuating heat and impurities. Physico-chemical monitoring is vital […]
