Could any of experts educate me something about smock? Does anyone measure resistivity of the smock? Is any qualification requirement for the vendor to clean the smock? How many times you can wash a smock? (someone told me 50 times only...I can see some calculator start going nuts on +,x $). or is it OK as long as the resistivity meet the requirement of EIA-STD-625?..Visual inspection for wear and tear is regular. any others? check resistivity every day?
