Try these first

1. 1.

   What does the Preservative Absorption Test measure?

   Hint

   Think about what we want to know about wood treatment.

2. 2.

   Why is retention important in wood preservation?

   It's related to keeping the wood safe from damage.

3. 3.

   What is the main aim of the Preservative Absorption Test?

   • To measure moisture content
   • To determine retention and penetration of preservatives
   • To evaluate wood strength

4. 4.

   True or False: The deeper the penetration of the preservative, the more effective it is.

   • True
   • False

   Hint

   Consider why depth might impact effectiveness.

5. 5.

   Consider a scenario where a new preservative is developed that claims to have double the effectiveness of existing preservatives. How would you conduct a comparative study to test its efficacy using the Preservative Absorption Test?

   Hint

   What controls need to be in place to ensure fair testing?

6. 6.

   Reflect on what environmental factors could alter your results in a Preservative Absorption Test, and describe how you would account for them.
