The table above shows the result of standard CE certification required mechanical strength tests on fabrics and seams to provide a general profile of the garment mechanical properties. These are a reflection of controlled lab tests and actual performance of nonwoven fabrics and films may vary.

Notes: Imm = Immediate breakthrough / nt = Not Tested / QNA = eQuivalent Not Available Chemicals are tested at a concentration of 100% or saturation unless otherwise stated. Beware! Chemical testing according to EN 6529 is conducted at 25% ^oC +/- 5^oC. permeation rates may vary considerably at higher ambient temperatures Material Safety Data Sheets on many commonly used chemicals can be found here. (Lakeland make no claim or guarantee that the information on these sheets is correct). Normalized breakthrough times are a reflection of controlled laboratory tests according to EN6529 (or previous versions EN 369 & EN 374-3). “Normalized Breakthrough” is defined as the time to reach a measured PERMEATION RATE of 1.0µg / min / cm². This DOES NOT indicate the time to any measured breakthrough of a chemical nor that NO TRACE of the chemical has permeated through the fabric in less than 480 Minutes. Further, results may vary according to lab, detection methods and sensitivity, and ambient conditions such as temperature. These results are therefor not intended to indicate any guaranteed duration of “safe use” for any garment but rather to provide a basic guide to preliminary selection and to indicate chemical protective capabilities relative to each other Chemical suit selection should also be made on the basis of design requirements as well as fabric chemical barrier Download Lakeland’s guide to permeation, penetration and chemical suit selection
