Clean any external parts of the test cell touched by the liquid. This test method determines resistance to penetration only. The specimen fails if a droplet of liquid appears or a aastm discoloration see 9. For more sensitive analysis use Test Method F to determine permeation. F are the standard methods of testing used for chemically resistant workwear.
Current edition approved January 10, Remove the specimen and gasket from the cell and discard. Random specimens shall be generated as described in Practice E This is therefore considered a general failure point. These procedures entail different hydrostatic pressures and durations of liquid exposure.
Your Flame-Resistant Clothing Refresh. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. 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.
B Procedure C is that speci? Finished items and specimens are particularly important areas for testing as they consist of discontinuous and seamed regions of protective clothing. For nonuniform samples, record the lowest values. In this test method, all procedures involve liquid exposure that is continuous over the duration of the test.
The values in parentheses are for information only. Areas such as hands, legs, eyes, face and torso should be completely protected. Of course, normal continuous regions of protective clothing are also tested for their effective barrier shielding abilities.
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 areas between different items of clothing and equipment.

NOTE 2—Material is transparent shatterproof-resistant plastic sheet. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. If this occurs, record the failure, and terminate the test. Passing results indicate that no liquid penetration asfm observed over the duration of the test exposure. If a retaining screen is used, include it in the report.
What are ASTM F Safety Standards? |
If not, one of the following methods has usually been effective in enhancing droplet visibility by producing a characteristic discoloration. Flush the test cell with an appropriate wash liquid to remove or render harmless any traces of the test chemical. Procedure D903 also has utility for assessing the robustness of protective clothing materials and assemblies as part of quality systems. It is the responsibility of the user awtm this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Last previous edition approved in as F – 99a. Specific hazards are given in Section 7.
What are ASTM F903 Safety Standards?
See Table 1 for parts and materials. The resistance to visible penetration of the test f9003 is determined with the liquid in continuous contact with the normally outside exterior surface of the test specimen. The deleterious effects of these chemicals can range from acute trauma such as skin irritation and burn to chronic degenerative disease, such as cancer.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
A Use of a retaining screen is optional. Used for other speci? The values in parentheses are for information only. NOTE 2—Material asfm aluminum. For more sensitive analyses, use either Test Method F or F to determine permeation.
This is done to determine their resistance to visible penetration, which occurs with continuous chemical contact to the outer portion of the clothing. If the material was taken from garments, report under subheadings for each material, composite, type of seam, or other constructions tested, and its position on the garment.
If the liquid passes through the specimen, the material fails the test for resistance to penetration of the liquid. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Use of a funnel is one way to make? Also, remember just assuming that the workwear you have chosen will properly protect you is a risk that is not worth risking injury.
Use Test Method F for this purpose. The droplet must remain easily visible to ensure that a droplet that penetrates the material will be seen.
