Formerly under the jurisdiction of Committee F23 on Personal ,Protective Clothing, and Equipment, this test method was withdrawn in February 2015. This ,standard, is being withdrawn without replacement due to its limited use by industry. 1. Scope. ... D737 Test Method for ,Air Permeability, of Textile Fabrics. Other ,Standards,.
The ,standard, test method for ,air permeability, is ASTM D737, which measures the ,air, passage rate.The ,standard, test method for moisture ,permeability, is ASTM DE96, which measures the water vapor pass-through rate.The two are totally different!Warmth is determined by how much ,air, the clothes can hold between the skin and the outside world, so there is a concept of how fluffy the down jacket is.Put ...
These effects comprise not only low ,air, temperatures but also humidity and ,air, velocity. Requirements and test methods of garments for ,protection, against cool environments are specified in EN 14058. The ,protective, effects and requirements of footwear, gloves and separate head wear are excluded from the scope of this ,standard,.
According to the definition of the national ,standard, GB 19082-2009 technical requirements for single-use ,protective clothing, for medical use, medical ,protective clothing, is a professional ,clothing, for medical personnel who contacts potentially infectious patients' blood, body fluids, secretions, particles in the ,air,, etc. to provide barrier and ,protection,.
Air permeability, is an important property for wovens and it depends on many parameters of the fabric. Thus, a theoretical determination is highly complex anddifficult in relating the parameters to the ,air permeability,. Therefore, establish of the ,air permeability, is usually made experimentally.
It seems that ,air permeability, characteristic of ,clothing, material is the major determinant in this respect since it enables better cooling. It can, thus, be concluded from the present data that for ,clothing, material with similar static thermal resistance, the higher the ,air permeability, value is, the lower is the physiological strain, which is in accord with the conclusion made by Havenith et ...
Clothing, for ,protection, against contact with blood and body fluids. Determination of resistance ,of protective clothing, materials to penetration by bloodborne pathogens— Test method using Phi-X174 bacteriophage. Note: These tests are typically conducted on fabrics, but they can be conducted on the garment seams as well.
5.2 ,Air permeability, is an important factor in the performance of such textile materials as gas filters, fabrics for ,air, bags, ,clothing,, mosquito netting, parachutes, sails, tentage, and vacuum cleaners. In filtration, for example, efficiency is directly related to ,air permeability,. ,Air permeability, also can be used to provide an indication of the breathability of weather-resistant and ...
