7.3. Durability and Biological Resistance Tests

Try these first

1. 1.

   What is a preservative absorption test?

   Hint

   Remember the 'PEN' acronym.

2. 2.

   Why is it important to test wood for insect resistance?

   Hint

   Consider the impact of pests on wood structures.

3. 3.

   What does the preservative absorption test measure?

   • Wood density
   • Preservative retention
   • Moisture content

   Hint

   Think about the significance of wood treatment.

4. 4.

   True or False: Fungal resistance tests measure the increase in wood weight after treatment.

   • True
   • False

   Hint

   Remember what happens to wood when it decays.

5. 5.

   Develop a testing plan for a new type of wood product that includes both preservative absorption and resistance tests. What factors will you consider in your methodology?

   Hint

   Think about all elements necessary for comprehensive testing.

6. 6.

   Discuss the implications of poor performance in either the preservative absorption test or the resistance tests on a construction project.

   Hint

   Consider the long-term effects on the structure and its occupants.
