"Acoustics -- Hearing protectors -- Part 3: Measurement of insertion loss of ear-muff type protectors using an acoustic test fixture"

ISO 4869-3:2007 specifies a method for measuring the insertion loss of ear-muff type hearing protectors using an acoustic test fixture. The method is applicable to the investigation of production spreads of performance as part of type approval or certification procedures, and to the investigation of the change of performance with age. It is intended to ensure that ear-muff hearing protector samples submitted for subjective testing of attenuation according to ISO 4869-1 have performances typical of the type. The method specified in ISO 4869-3:2007 is not applicable as the basic test for type approval. Performance data obtained by this method are not intended to be quoted as representing the real-ear sound attenuation of an ear-muff, nor the protection provided by the ear-muff.

"Protective clothing -- Protection against chemicals -- Determination of resistance of protective clothing materials to permeation by liquids and gases"

ISO 6529:2013 describes laboratory test methods to determine the resistance of materials used in protective clothing, including gloves and including footwear, when the footwear is an integral part of the clothing, to permeation by liquid or gaseous chemicals under the conditions of either continuous or intermittent contact. Method A is applicable to testing against liquid chemicals, either volatile or soluble in water, expected to be in continuous contact with the protective clothing material. Method B is applicable to testing against gaseous chemicals expected to be in continuous contact with the protective clothing material. Method C is applicable to testing against gaseous and liquid chemicals, either volatile or soluble in water, expected to be in intermittent contact with the protective clothing material. These test methods assess the permeation resistance of the protective clothing material under laboratory conditions in terms of breakthrough time, permeation rate and cumulative permeation. These test methods also enable qualitative observations to be made of the effects of the test chemical on the material under test. These test methods are only suitable for measuring permeation by liquids and gases. These test methods address only the performance of materials or certain materials' constructions (e.g. seams).

"Protective clothing -- Protection against heat and fire -- Method of test: Evaluation of materials and material assemblies when exposed to a source of radiant heat"

ISO 6942 specifies two complementary methods (method A and method B) for determining the behavior of materials for heat protective clothing subjected to heat radiation. These tests are carried out on representative single or multi-layer textiles or other materials intended for clothing for protection against heat. They are also applicable to assemblies, which correspond to the overall build up of a heat protective clothing assembly with or without underclothing. Method A serves for visual assessment of any changes in the material after the action of heat radiation. With method B, the protective effect of the materials is determined. The materials may be tested either by both methods or only by one of them. The tests carried out according to these two methods serve to classify materials; however, to be able to make a statement or prediction as to the suitability of a material for protective clothing, it is necessary to take into account additional criteria. Since the tests are carried out at room temperature, the results do not necessarily correspond to the behavior of the materials at higher ambient temperatures and therefore are only to a limited extent suitable for predicting the performance of the protective clothing made from the materials under test.

"Radiation protection -- Clothing for protection against radioactive contamination -- Design, selection, testing and use"

Gives the characterisitcs of two types of clothing: ventilated-pressurized garments and unventilated-unpressurized garments. These characteristics include the manufacture materials, design and size, accessories, breathing air supply and internal ventilation. Annex A describes a test method according to which any new type of garment can be assigned a protection factor that makes it easier for the user to make a choice. Annexes B and C give methods for measuring leak tightness and air supply flow rates of ventilated-pressurized garments. Annex F gives, for guidance, recommendations for choosing protective clothing.

"Protective clothing against heat and flame -- Determination of heat transmission on exposure to flame"

Specifies a method for comparing the heat transmission through materials or material assemblies used in protective clothing. Materials are ranked by calculation of a heat transfer index, which is an indication of the relative heat transmission under the specified test conditions. The heat transfer index should not be taken as a measure of the protection time given by the tested materials under actual use conditions.
