摘要

本研究的目的是确定木环数和MC标准试验对白蚁取食的影响。引进种(台湾Coptotermes formosanus)在美国木材保护协会(AWPA) E1-97标准实验室测试中进行了测试。与E1-97规定的4 - 6环每英寸(RPI)相比，环数在6 - 10环每英寸(RPI)范围内的样品有更高的重量损失，但没有显著差异。关于MC，确定了比AWPA E1目前规定的更低的湿度水平比ASTM D3345中达到的更高的MC更好。在ASTM D3345中，建议将样品放置在沙子上，而不是掩埋过程。

The Effect of Variables on Laboratory Termite Testing: Part 3 - Test Block Density and Moisture Content

The objective of this study was to determine the impact on termite feeding of wood ring count and MC in standard tests. Introduced species ( Coptotermes formosanus ) were tested in an American Wood Protection Association (AWPA) E1-97 standard laboratory test. Samples with a ring count in the range of 6 – 10 rings per inch (RPI) had a higher, but not significantly different, weight loss than the 4 – 6 RPI specified by E1-97. With respect to the MC, it was determined that a lower level of moisture than that currently specified by AWPA E1 would be preferred over the higher MC achieved in ASTM D3345. Sample placement on top of the sand was recommended over the burial procedure in ASTM D3345.
