Standards & Guidelines<\/span><\/h3>\n<\/div>
<\/div>\n
The meaning and importance of standards and guidelines has increased rapidly within the last 30 years. We accordingly recommend checking the suitability of a product for a certain purpose before using. In order to facilitate this decision, we would like to list various categories for some product groups as follows.<\/div>\n
….<\/span><\/div>\n

Respirators or Filters<\/h2>\n
\n

P1:<\/strong> Against non-toxic and harmful fine dust up to 4-times the limit.
\nNot against particles of carcinogenic and radioactive materials, micro-organisms
\n(viruses, bacteria, fungus and its spores) and enzymes.<\/p>\n

P2: <\/strong>Against harmful materials up to 10-times the limit.
\nNot against particles of radioactive materials, viruses and enzymes.<\/p>\n

P3:<\/strong> The more toxic a material is, the lower will be its limit.
\nIn order to prevent an exceeding, it is strongly recommended to use filters of that category
\nwhich protect up to 30-times the limit.<\/p>\n<\/div>\n

Protective Gloves<\/h2>\n
\n

Category I:<\/strong>
\nThis category contains light protection gloves, the user is able to judge in regard of minor risks as for instance household or exposure to weather and sunbeams.<\/p>\n

Identification of gloves: CE mark<\/p>\n

Category II:<\/strong><\/p>\n

This category contains protection gloves against medium risks, tested according to EN 388 (protection against mechanical risks), EN 374-2 (protection against microbiological risks) and EN 374-3 (protection against chemical risks). Furthermore, the user himself is able to evaluate the immediate effect.<\/p>\n

Identification of gloves: CE mark<\/p>\n

Category III:<\/strong>
\nThis category contains protection gloves against complex and irreversible risks for a limited period of time. The gloves are tested like in category II but the user is not able to evaluate the immediate effect. Additionally, the production plant and all relevant products are controlled on a regular basis by a notified body stated on the glove.<\/p>\n

Identification of gloves: CE mark and the identification number of the notified body.<\/p>\n

AQL-value:<\/strong>
\nA<\/strong>cceptable Q<\/strong>uality L<\/strong>evel
\nProcedure to determining the quality. In reference to DIN EN 455 a value for tightness of 1,5 for disposable medical gloves had been determined.<\/p>\n

\nThe pictogram “limited chemical resistance” applies for gloves that pass the penetration test but do not reach a minimum breakthrough time of 30 minutes with at least three chemicals in the definition list.<\/p>\n

**<\/strong>
\nThe pictogram “chemical resistance” must be accompanied by a three-digit letter code. That code refers to the three chemicals (from a list of twelve defined standard chemicals) with a determined breakthrough time of at least 30 minutes.<\/p>\n

Protective Clothing<\/h2>\n

Cat. III: <\/strong>Protection against minor risks
\nCat. II<\/strong>I:<\/strong> Protection against medium risks
\nCat. III: <\/strong>Protection against high risks<\/p>\n

There is a division of category III in 6 types (from 6 – 1):<\/p>\n

Type 6: <\/strong>limited spray density
\nType 5:<\/strong> density against particles
\nType 4:<\/strong> density against spray
\nType 3:<\/strong> liquid-tight
\nType 2:<\/strong> none gas-tight
\nType 1: <\/strong>gas-tight<\/p>\n

Category III:<\/strong>
\nIn regard of type 6 – 4, breathable materials can normally be applied; this is highly dependent on the barrier properties of the different materials as well as the work to be carried out.<\/p>\n<\/div>

Protective Shoes<\/h2>\n

S1:<\/strong>P <\/strong>steel or plastic cap and closed heel section,
\nS1:<\/strong>P <\/strong>antistatic (depends on model), energy absorption capacity in heel area<\/span><\/p>\n

S1P: <\/strong>steel or plastic cap and midsole against penetration, not watertight<\/p>\n

S2:<\/strong>P<\/strong> like S1, but only for sectors with wet influences<\/p>\n

S3:<\/strong>P <\/strong>like S2, additional midsole against penetration and more profiled outsole<\/p>\n

ESD<\/strong> (E<\/strong>lectro S<\/strong>tatic D<\/strong>ischarge)<\/h2>\n

Protection shoes are described as ESD shoes if the peak is between 105 and 107 ohm. These shoes are recommended if it is necessary to reduce the electronic loading by deduction of the electrostatic loading.<\/p>\n

Pollution, moisture and bending can significantly influence the electrical resistance.<\/p>\n

The EN standards EN 344, 345, 346 and 347<\/strong> regulate the basic requirements for safety-, protective- and working shoes for commercial use.<\/p>\n

EN 344: <\/strong>Requirements and test procedures for for safety-, protective- and working shoes for
\nEN 344: <\/strong>commercial use<\/p>\n

EN 345: <\/strong>Working shoes with steel cap (resilient up to 200J)
\nEN 345: <\/strong>(see S1 – S3 – categories)<\/p>\n

EN 346: <\/strong>Working shoes with steel cap (resilient up to 100J)<\/p>\n

EN 347:<\/strong> Working shoes without toe cap<\/p>\n<\/div>
