Additional Tests Made Possible by Using the latest Equipment

Bodycote Testing Group’s very latest equipment can also measure carbon, sulphur and phosphorus content. These elements were previously either impossible to measure or were measured very inaccurately with less advanced equipment.
Choice of Analysis Equipment

The choice of equipment for a particular application will depend upon such factors as:

· The material type

· Access

· Safety considerations

· Level of analytical accuracy required

· Power source availability

· Component size.
Testing Flexibility

Whatever the application Bodycote Testing Group have the most suitable equipment for the job.

Bodycote Testing Group firmly believe in the fundamental importance of proper operator training and laboratory support for our PMI services, viewing it as an extended laboratory service. An experienced site services team is on standby at all times to deliver PMI services and to provide replication, hardness testing and related on-site metallurgical services.

Replication is widely used as a means of examining plant in-situ for material damage or defects and is often used to assess creep damage in high temperature applications. It requires highly trained and skilled technicians with full laboratory support.
