How Sticky Mats Work
Blue or White, Tacky Sheets are numbered 1-30 so you can keep track of how much dirt and dust your Sticky Mats are absorbing off of shoes and wheels moving over them.
Made with adhesive on the bottom, the sticky mats can sit in front of doorway entrances and exits without being picked up off the ground by foot traffic.

American Standards. Before international cleanroom classifications and standards were adopted by the International Organization for Standards (ISO), the U.S. General Service Administration’s standards (known as 209E) were used by most manufacturers in most countries.
Federal Standard 209E classified clean rooms based on how many .5 micron particles could be counted in the room per cubic foot. If a clearness had 100 0.5 micron particles per cubic foot or less it was classified as a class 100 room. This standard divided cleanrooms as being in one of 6 classes: Class 1, Class 10, Class 100, Class 1000, Class 10000, and Class 100000.
What is a micron particle? One micron is one-hundredth the width of a human hair. The smallest particle seen with the naked eye is a 10 micron particle. Although cleanrooms are under positive pressure, micro-organisms can exist on clothing and unwashed hands, and keep in mind humans shed our outermost layer of skin every 24 hours: 1 billion flakes every 24 hours. One flake is 35 microns.
International Standards. The international standard developed by the ISO (called ISO 14644-1) was adopted in part from British Standard BS 5295, but made minor modifications: (1) it changed the measurements of micron particles to cubic meters from cubic feet, (2) it required measurements of both 0.5 and 0.1 micron particles for ISO Class 3, 4, and 5 cleanrooms, (3) required 0.5 micron particle readings for ISO Class 6, 7, and 8 cleanrooms, and (4) added two cleaner classes: ISO Class 1 and ISO Class 2.
