Standard Field Test for the Evaluation of Wood Preservatives to be Used Above Ground (UC3A and UC3B); L-Joint Test
评估地面上使用的木材防腐剂的标准现场试验(UC3A和UC3B);L-联合试验
The method is suitable for evaluating the efficacy of preservative formulations to protect non-durable timber from decay when used in above ground exterior applications. Its primary application is for testing systems for UC3A applications such as exterior joinery (protected by conventional finishing systems), but is also applicable for testing UC3B uncoated applications.
