EN 136 – STANDARD FOR FULL FACE MASKS
Teh EN 136 standard sets the minimum requirements for face masks that are used as part of a respiratory device, or any full face mask that includes a respiratory filter. A full face mask is defined as a protective mask that covers the eyes, nose, mouth and chin, and they are commonly made from natural rubber, silicone rubber, or EPDM with clear plastic visors. EN 136 certified masks are divided into three classes, with a Class 3 rating representing the highest level of protection. The classes are defined as follows:
EN 136 CLASS 1
Full face masks rated class 1 are suitable forĀ light duty work and are low maintenance. These masks provide enough protection for low danger environments, and are often disposable or designed for infrequent use.
EN 136 CLASS 2
Class 2 full face masks are suitable forĀ general duty work, and include maintainable parts. These masks will provide a higher level of protection, and are designed to be able to clean, repair or replace parts, making them suitable for frequent or everyday use over longer periods.
EN 136 CLASS 3
This is the highest level of specification under EN 136. Class 3 masks are designedĀ for heavy duty use and fire fighters, and carry the most protection, durability and maintenance ability of all face masks.
The classification system of EN 136 makes it easy to identify the general quality and protection level of your face mask at a glance. EN 136 specification is based on a number of requirements and tests, including:
- Field of vision – The amount of space the mask allows you to see in your peripheral vision.
- Impermeability – The amount of dust, gas or particulate the mask will allow through.
- Temperature stability – The degree to which a mask retains its protective qualities at extreme temperatures.
- Concentration of carbon monoxide – The degree to which the mask protects you from CO.
- Breathing resistance – How much strain the mask puts on your ability to breathe easily.
- Speech diaphragms – How much the mask restricts your ability to speak clearly with others.
