Note. The choice depends on the capture media analysis techniques. 3.3 Trapping medium continues to flow through the penetration test cell trapping chamber without being re-used and recycled test mode. 3.4 Trap mass media fixation test mode. 3.5 In the intermittent contact test, the chemical protective material samples and chemicals in each cycle duration of the contact time. 3.6 From the start of the test chemical was first detected interval. Note. With time depends on the sensitivity and frequency of sampling methods. 3.7 Open system chemical penetration rate of permeability standard time. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 23462-2009_English be delivered?Answer: Upon your order, we will start to translate GB/T 23462-2009_English as soon as possible, and keep you informed of the progress.
