Summary of relevant information contained in. ASTM F Standard Test Method for Resistance of. Materials Used in Protective Clothing to Penetration by . Designation: F – 03 Standard Test Method for Resistance of Materials Used in Protective Clothing to Penetration by Liquids1 This standard. ASTM F Standard Test Method for Resistance of Materials Used in Protective Clothing to Penetration by Liquids.
For more sensitive analyses, use either Test Method F or F to determine permeation.
Precision and Bias If the material aztm taken from garments, report under subheadings for each material, composite, type of seam, or other constructions tested, and its position on the garment. Also, remember just assuming that the workwear you have chosen will properly protect you is a risk that is not worth risking injury.
Special means used to seal specimens in the test cell should be documented in the report. Use Test Method F to provide a complete evaluation of the liquid integrity of protective clothing or ensembles, particularly areas of the clothing or ensembles that cannot be directly assessed by this test method, such as interface d903 between different items of clothing and equipment. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
If not, one of the following methods has usually been effective in enhancing droplet visibility by producing a characteristic discoloration. However, it is possible that differences in chemical and molecular properties for example, surface tension lead to different results. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Use of a funnel is one way to make? Passing results indicate that no liquid penetration was observed over the duration of the test exposure.
Used for other speci? It is important to note that the ASTM F standard testing does not apply to the crotch area or the finger tip areas of gloves. Resistance to permeation and degradation should be determined by other test methods.
Procedure D also has utility for assessing the robustness of protective clothing materials and assemblies as part of quality systems. In this test method, all procedures involve liquid exposure that is continuous over the duration of the test.
If the liquid passes through the specimen, the material fails the test for resistance to penetration of the liquid. Current edition approved January 10, This test method determines resistance to penetration only. However, it is possible that differences in chemical and molecular properties for example, surface tension may lead to different results. BoxChicago, IL Summary of Test Method 4. If the temperature of the cell and liquid were different at the start of the test, report both.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. These procedures entail different hydrostatic pressures and durations of liquid exposure. This is done to determine their resistance to visible penetration, which occurs with continuous chemical contact to the outer portion of the clothing. If a retaining screen is used, include it in the report.
The deleterious effects of these chemicals can range from acute trauma adtm as skin irritation and burn to chronic degenerative disease, such as cancer. A Use of a retaining screen is optional.
The purpose of the zstm is to limit distention of the test specimen to 0. Last previous edition approved in as F – 99a. Flush the test cell with an appropriate wash liquid to remove or render harmless any traces of the test chemical.
For more sensitive analysis use Test Method F to determine permeation. Random specimens shall be generated as described in Practice E Use Test Method F for this purpose. Specific hazards are given in Section 7.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of aastm standard. Finished items and specimens are particularly important areas for testing as they consist of discontinuous and seamed regions of protective clothing.
However, it is also appropriate to establish sampling plans based on a specific acceptable quality limit using a larger number of specimens, depending on the application of the test method. If this occurs, record it as a failure and terminate the test.

F — 03 FIG. The resistance to visible penetration of the test liquid is determined with the liquid in continuous contact with the normally outside surface of the test specimen. F03 is recommended that any special means used to seal specimens in the test cell be validated for providing sufficient integrity of the specimen in the test cell, not contribute to specimen damage, and not interfere with the observation of liquid penetration.
