a All concentrations in the table are cumulative, e.g. for ISO Class 5, the 10 200 particles shown at 0,3 μm include all particles equal to and greater than this size. b These concentrations will lead to large air sample volumes for classification.

The ICS uses an hierarchical classification, which consists of three nested levels called fields (Level 1), groups (Level 2) and sub-groups (Level 3). Each field is subdivided into groups, which are further divided into sub-groups. All classification levels are designated by a classification code (called notation) and a title.
These are widely used in other countries. Their classifications broadly reflect the SAE's specifications, DOT 3 is equivalent to SAE J1703 and ISO class 3, DOT 4 to SAE J1704 and ISO class 4, etc. [6] All DOT compliant fluids must be colorless or amber, except for DOT 5 silicone, which must be purple.

Class 3: Flammable Liquids A flammable liquid is a liquid having a flash point of not more than 60 °C (140 °F), or any material in a liquid phase with a flash point at or above 37.8 °C (100 °F) that is intentionally heated and offered for transportation or transported at or above its flash point in a bulk packaging.
The European respirator standards refer to the filtering classification by EN 149, EN 14683, and EN 143, all European standards of testing and marking requirements for respirators. [1] FFP standard masks (where FFP stands for filtering facepiece) [2] cover the nose, mouth and chin and may have inhalation and/or exhalation valves. [1]
