1973年,11种不同合金和镀有合金的钉子钉入了经加铬砷酸铜(chromated copper arsenate)或含氨砷酸铜(ammoniacal copper arsenate)处理的南方松中。一组试件暴露于相对湿度97%～100%,温度80℉(27℃)下14年,另一组试件埋在麦迪逊州的一山谷的暴露试验场土壤中17年。用测量重量的减少
In 1973, eleven different alloys and alloyed nails were spiked into southern pine treated with chromated copper arsenate or with ammoniacal copper arsenate. One set of coupons was exposed to 97% -100% RH for 14 years at 80 ° F (27 ° C) and the other set was buried 17 years in exposed test soil in a valley in Madison. With the measurement of weight reduction
