ATEX is the summary of "ATmosphère EXplosible". This covers all situations in which persons are exposed to a risk of explosion. These may be powders, fumes (e.g., gasoline), but also dust clouds such as toner or flour.
In order to limit the risks as far as possible, an "explosion safety document", ie a risk analysis, is used to divide into more or less vulnerable operating zones.The classification of the zones makes the risk of explosion clear. The European Directives (ATEX 100A ~ 1994/9 / EC and ATEX 118A ~ 99/92 / EC) have been in place since 2003 for new installations. From 1 July 2006, existing production facilities will also have to comply with these standards. ATEX 100A refers to installations and equipment, while ATEX 118A is relevant to the workplaces in the hazardous areas and to persons working there. In the OSH legislation, EN ATEX 95 is used when it comes to products. When it comes to working environments, it is referred to the EN ATEX 137 standard. Persons who wear clothes, shoes or gloves fall under the working environment, ie under ATEX 137. It should be noted here that the worn clothing must have a derivative of 1000V to 500V within 5 seconds. Our concept ATEX PRACTICE PROOF connects between people and their work environment. All Hydrowear garments are tested according to this standardization. ATP ATEX electrostatic dissipative requirements practice proof, ATEX
EN 14605 / EN 13034-6 protection against chemicals type 4 (spray tight) or type 3 (liquid tight)
The standardization is determined by the test method for the requirements that the clothing must meet for protection against humans against certain chemicals. It mostly concerns clothing with a liquid dense coating or laminate. Part of EN14605 concerns permeation time. (Breakthrough at Molecular level) of the clothing which is tested according to EN374-3 or ISO 6529. The classification depends on the permeation time. In addition to types 3 and 4, type 3 or 4 PB is also permitted. PB means protection for parts of the body. (PB = partial body protection)
The jet and spray tests, which are only used for whole garments, are no longer needed.
|class 1||10 min|
|class 2||30 min|
|class 3||60 min|
|class 4||120 min|
|class 5||240 min|
|class 6||480 min|
EN13034-6 PROTECTION AGAINST LIQUID CHEMICALS TYPE 6
The standardization is determined by the test method for the requirements that the clothing must meet for limited protection against splashes of liquid chemicals. Type 6 clothing is not completely liquid-tight and offers less protection than Type 3 and 4 clothing. For type 6 clothing, fluorocarbon finishing is usually sufficient. In addition to Type 6, a Type 6 (PB) is also allowed here.
The table shows the test results for the different materials and chemicals. The fabric label on the label indicates the material of your clothing.

EN 1149 Static Electricity
EN1149 Protection against static electricity
Standardization is determined by the test procedure for the requirements that the garment must satisfy when protected against electrostatic charges in an environment where there is a risk of explosion.
The aim of this protective clothing is to limit the build-up of charge and the distribution of charge on the outer fabric in an explosive environment. By changing the surface tension of the substance, the charge buildup can be measured.
There are 3 methods of measurement to determine the charge in a garment and to measure how conductive, dissipative (antistatic) or insulating it is.
Heterogeneous: fabric with a conductive fiber, the surface resistance <109W (fabric with carbon thread)
Homogeneous By anti-static hydrophilic additives in the coating, whereby the surface resistance <5 x 1010 W.
In-Homogeneous: Fiber-covered fabric with protective cover with a carbon core.
1149-1 Is the test procedure for determining the surface resistance of the fabric (in ohms)
1149-2 Is the test procedure for determining the passage resistance of the fabric (in ohms)
1149-3 Is the test procedure for determining the unloading times of the fabric in seconds. In addition the possibility of the "Shielding effect" (Shielding of the charge, which is integrated into the fabric (HBM) expressed in s <0.2.) It can determine the antistatic effect of an antistatic thread (as for example Negastat).
1149-4 Structure and influence of tissue including accessories (e.g., buttons, zippers) that may affect the discharge.
1149-5 A summary of the audited standards on the observed test results of the tissue. The general description of the methods used.

The lower the value, the better the breathability
|EN ISO 11092||class 1: Ret > 40 m²- Pa/W|
|On the original||class 2: 25 m²- Pa/W < Ret < 40 m². Pa/W|
|On layer construction||class 3: 15 m². Pa/W < Ret < 25 m².Pa/W|
|class 4: Ret < 15 m².Pa/W|
Ret is the abbreviation for Retention = resistance. The lower the pore resistance, the better the breathability. The highest attainable class is class 4 with a Ret below 15
EN 50286 Isolation
European Standard NEN-EN 50286: 1999
Electrically insulating protective clothing for use in low-voltage installations.
This standard applies to electrically insulating protective clothing used by qualified persons when working on conductive parts or in the vicinity of conductive parts of low-voltage installations with nominal voltages up to 500 V AC or up to 750 V DC.
The protective clothing is tested under heavy loads.
The textiles are tested for insulating properties, using the voltage of 2.5 kV (rms). The leakage current must not exceed 0.2 mA.
In addition, the material must pass the arc fault test: NEN EN IEC 61482-1-2 4KA.
European security requirements are increasingly tightened. In order to serve the European market, suppliers should adapt their product development.
For these new test conditions, the requirements are so high that it has been very difficult for manufacturers of workwear to meet them.
Hydrowear has invested a lot of work in new developments over the last few years to improve the Hydrowear safety clothing.
Hydrowear has succeeded in developing a textile fabric that can meet the high requirements of the new tests and also offers a comfortable fit.
In addition to insulating safety clothing, people also need to wear insulating shoes, gloves and face shields.
In addition to companies for electrical engineering, energy and industry, the manufacturers and repairers of hybrid cars are also among the customers. Repairs to hybrid cars can generate voltages up to 1000V.
