TS EN 14593-2 Respiratory Protective Devices - Demand Valve, Compressed Air Line Breathing Apparatus - Part 2: Positive Pressure Half Mask Apparatus - Rules, Experiments, Marking

The BS EN 14593-2 standard has been developed by the British Standards Institute (BSI) to explain the properties, test methods and marking criteria of positive pressure half-masked equipment used with a breathing-related protective device with demand valve and compressed air line. This standard was published in our country by the Turkish Standards Institute (TSE) with the following title: TS EN 14593-2 Respiratory protective devices - Demand valve, compressed air line breathing apparatus - Part 2: Positive pressure half mask apparatus - Rules, experiments, marking.

The standard in question describes the minimum characteristics of a compressed air line respirator with demand valve for use with positive pressure half mask equipment as a respiratory protective equipment.

There are many different respiratory hazards for those working in hazardous areas. Correct respiratory protective equipment should be chosen which reduces the risks determined depending on the field of activity of the enterprise to acceptable levels. For this, it is necessary to understand the different types of breathing equipment available, protection factors and compatibility tests.

Different types of airflow affect the choice of a respiratory protection equipment. There are two different types of airflow: positive compressed air flow and negative compressed air flow.

Respirators providing positive compressed air flow provide a positive pressure in the face area during exhalation. Respiratory devices that provide negative compressed air flow draw air to the facial area through negative pressure created by the person's breathing.

Meanwhile, half masks are face masks that are designed to provide effective protection against gas, vapor and particle hazard and cover only the mouth, nose and chin.

Within the scope of breathing apparatus compatibility tests carried out by our organization EUROLAB, testing services in accordance with TS EN 14593-2 standard are also provided.
