Quality Control

Drennan works with suppliers to ensure the implementation of both our own and customers’ quality control standards. Following initial factory audits, together with our customers, we design specific quality control procedures for each project. We then apply quality control with a variety of methods including:

1. pre-planned factory inspections

2. random factory inspections

3. independent testing of materials composition, mechanical properties, dimensions. Drennan is experienced in the following test procedures:

Hardness
Chemical composition
Standard Mechanical properties
Dimensional
X-ray
Ultrasonic
Magnetic resonance
Charpy
Reflectivity
Elongation
Hardenability

4. pre-delivery final inspections

For those goods, which do not meet the declared standard, we advise the customer of the discrepancy and act on the customer’s decision be that rejection or conditional acceptance.
