There are many different chemical protective suits commercially available, and although they are CE certiﬁ ed, there are very wide ranging performance differences for products meeting the same certiﬁ cation Types . Faced with a bewildering choice and the complexity of the certiﬁ cation information, what criteria should be used to select the right protective clothing? A short summary of the European standards for chemical protective clothing and a chemical protective clothing selection guide is provided to assist you in this task. Additional information on CE marking can be found in Annexe 2.
CE Marking To facilitate the choice of garment, the European Union has deﬁ ned harmonised product standards for six levels of protection (referred to as Types ) within Category III chemical protective clothing (see table below). The certiﬁ cation of a suit to a particular protection type represents its overall tightness against a particular form of exposure (gas, pressurised liquids, sprays and dust).
It should be noted that its certiﬁ cation does not necessarily mean that the suit is 100% impervious to this type of exposure. It only means that the suit meets the minimum requirements of the speciﬁ c product standard. The manufacturer is also obliged to state the performance levels of the constituent materials and seams, known as performance Classes .
