2.11. Field Performance Evaluation

Try these first

1. 1.

   Define what retention means in the context of timber preservation.

   Hint

   Think about how much preservative remains within the wood.

2. 2.

   What measurement method is often used for penetration checks in timber?

   Hint

   Consider methods involving a sample extraction.

3. 3.

   What does retention refer to in timber preservation?

   • The depth of preservative
   • The amount of preservative
   • Both A and B

   Hint

   Consider how we gauge the success of a preservative treatment.

4. 4.

   True or False: Core sampling can be used to evaluate both retention and penetration.

   • True
   • False

   Hint

   Think about the role of a core sample.

5. 5.

   You have treated timber showing early signs of decay. Outline the procedure you would follow to assess retention and penetration.

   Hint

   Consider your initial assessments and follow the testing procedures as outlined.

6. 6.

   Design a maintenance schedule for timber structures that includes both retention checks and service condition monitoring. What factors would you consider?

   Hint

   Think of different external conditions influencing the maintenance frequency.
