What is Material Evaluation? 

Material Evaluation is used as a tool to determine the purpose of the components intended function in its application. Making sure previous processes applied have not compromised the effectiveness of the component.

At Lavender International we provide 4 Material Evaluation courses, these include:

Conductivity testing courses offer training in the use of Eddy Current Inspection to monitor the heat treated condition and mechanical properties.

Hardness training includes training in the use of indentation hardness machines to monitor the surface hardness of a range of ferrous and non-ferrous alloys.

Acid Etch Inspection involves training in the surface preparation of metals to enhance the visual evaluation of surface properties and condition by acid etching.

Anodic Flaw Detection involves training in the the surface preparation of aluminium to enhance the visual evaluation of surface properties after chromic acid anodising.

What are the responsibilities of a individual who is certified to Material Evaluation Level 2?

An individual certified to Material Evaluation Level 2 has demonstrated competence to perform NDT according to Material Evaluation procedures. Within the scope of the competence defined on the certificate, Level 2 personnel may be authorised by the employer to:

  • Select the Material Evaluation technique for the test method to be used;
  • Define the limitations of application of the testing method;
  • Translate NDT codes, standards, specifications and procedures into NDT instructions adapted to the actual working conditions;
  • Set up and verify equipment settings;
  • Perform and supervise tests;
  • Interpret and evaluate results according to applicable standards, codes, specifications or procedures;
  • Prepare Material Evaluation written instructions
  • Carry out and supervise all tasks at or below level 2;
  • Provide guidance for personnel at or below level 2, and
  • Report the results of Material Evaluation test

Material Evaluation Level 2 training at Lavender International covers the following:

HT and CT courses can be a combined into one course (2 days training and 2 days exam).

Tensile training courses also available – ask for further details.

To supplement the training, examinations can then be taken in accordance with Prime Contractors Specifications. For Example:

AIRBUS ASI6-10

BAE SYSTEMS R05-6267

WESTLAND HELICOPTERS WHPS 439

HONEYWELL AEROSPACE YEOVIL NGPS 439

GKN (IOW) WAPS 25-04

BOEING BSS 7646 AND BSS 7651

If working in accordance with the above aerospace specifications, the Material Evaluation techniques have to be incorporated into an employer written practice in accordance with EN 4179/NAS 410 and their use controlled by the nominated/responsible Level 3.

The Work Experience requirements for Material Evaluation Methods are the following:

Method – LEVEL 2 Minimum Experience Hours
AFD 40
CT 40
AEI 40
HT 24

Material Evaluation courses are taking place at Lavender International in the UK and are also available on-site.

Dates are dependant upon demand, enquire for further details to the UK Office.

 

Overalls/Lab Coat
Safety Boots

All other equipment and training materials (with the exception of Level 3 Text Books) are provided by Lavender International.
Protective gloves, protective eye glasses and plastic aprons are also available for the use of students.
