Five glove materials were tested for permeation by two commonly used formulations of pentachlorophenol (PCP). Permeation was conducted using the method used in two prior studies by NIOSH. The lower limit of PCP quantitation in the receiving side of the permeation cell was 70 parts per billion (ppb). When challenged with a 4.3% PCP in diesel oil solution, both the Dayton Flexible Products Triflex (PVC) and the Best 64 NFW (natural rubber) gloves exhibited breakthrough times thirty seconds after exposure. The Playtex #835 (latex/neoprene) glove exhibited breakthrough after sixty minutes, but showed a five fold greater rate of permeation than the Dayton and the Best glove. Neither the Edmont Sol-Vex (nitrile rubber) nor the Granet Glo-Gluv (PVC) gloves had been permeated after testing for 8 and 16 hours respectively. Following challenge with a 4.2% sodium pentachlorophenate solution, only the Best (natural rubber) glove allowed breakthrough; this only thirty seconds after exposure. Neither the Dayton (5 hours), Playtex (7.5 hours), Edmont (15.5 hours), nor Granet (15.5 hours) gloves had been permeated following completion of testing after the listed duration. This study has shown that different gloves offer differing resistance to permeation by PCP based upon the composition of the glove and the PCP formulation tested.
对五种手套材料进行了测试，以检测其对两种常用五氯苯酚（PCP）配方的渗透性。渗透测试采用了美国国家职业安全与健康研究所（NIOSH）之前两项研究中使用的方法。渗透池接收侧PCP的定量下限为十亿分之七十（ppb）。当用柴油溶液中4.3%的PCP进行挑战时，Dayton Flexible Products Triflex（聚氯乙烯）手套和Best 64 NFW（天然橡胶）手套在暴露30秒后均出现了穿透时间。Playtex #835（乳胶/氯丁橡胶）手套在60分钟后出现穿透，但渗透率比Dayton和Best手套高五倍。Edmont Sol-Vex（丁腈橡胶）手套和Granet Glo-Gluv（聚氯乙烯）手套在分别测试8小时和16小时后均未被渗透。在用4.2%的五氯酚钠溶液进行挑战后，只有Best（天然橡胶）手套出现了穿透；这仅在暴露30秒后。在按列出的持续时间完成测试后，Dayton（5小时）、Playtex（7.5小时）、Edmont（15.5小时）和Granet（15.5小时）手套均未被渗透。这项研究表明，根据手套的成分和测试的PCP配方，不同的手套对PCP渗透的抗性不同。
