Material testing
LEFFER maintains its own materials testing laboratory certified according to DIN EN ISO/IEC 17025, which delivers fast and accurate results for quality assurance during production.
Thanks to its close connection to our production facilities, tests can be carried out and evaluated immediately – efficiently, reliably, and with the highest degree of accuracy.
Our laboratory has a wide range of stationary and mobile testing equipment at its disposal, enabling us to examine almost all metallic materials. This ensures that our products meet the highest quality and safety requirements. Our materials testing is an integral part of our quality management system and contributes significantly to the durability, safety, and reliability of our products.
With this range of services, LEFFER ensures that materials, welded joints, and components meet the required specifications at all times—from incoming goods inspection to final acceptance.
