F — 03 FIG. Passing results indicate that no liquid penetration was observed over the duration of the test exposure.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. See Table 1 for parts and materials. Your Flame-Resistant Clothing Refresh. The resistance to visible penetration of the test liquid is determined with the liquid in continuous contact with the normally outside exterior surface of the test specimen.

What are ASTM F903 Safety Standards?

NOTE 2—Material is aluminum. If this occurs, record the failure, and terminate the test. NOTE 2—Material is transparent shatterproof-resistant plastic sheet. In this test method, all procedures involve liquid exposure that is continuous over the duration of the test. Use of a funnel is one way to make? However, it is possible that differences in chemical and molecular properties for example, surface tension may lead to different results.

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 test method determines resistance to penetration only. If the temperature of the cell and liquid were different at the start of the test, report both.


If this occurs, record it as a failure and terminate the test. Suggestions are provided for how to select an appropriate procedure for liquid contact.

Originally approved in Remove the specimen and gasket from the cell and discard. Clean any external parts of the test cell touched by the liquid. The droplet must remain easily visible to ensure that a droplet that penetrates the f90 will be seen. A transparent cover see Fig.

This standard is subject to revision at any time by the responsible technical committee and must be aztm every? The values in parentheses are for information only. NOTE 2—Material is steel. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

F are the standard methods of testing used for chemically resistant workwear.

What are ASTM F Safety Standards? |

To make sure you stay safe while around corrosive chemicals, check that the garment you are wearing has been properly tested and meets the regulations and f9003 standards associated with the chemicals you are working with or the standards that your employer sets.

Test specimens of protective clothing are exposed to a variety of chemical and molecular properties. Use Test Method F to provide a complete evaluation of the liquid integrity of protective clothing or ensembles, particularly areas asym the clothing or ensembles that cannot be directly assessed by this test method, such as interface areas between different items of clothing and equipment.

Areas such as hands, legs, eyes, face and torso should be completely protected. For more sensitive analysis use Test Aztm F to determine permeation. Procedure D also has utility for assessing the robustness of protective clothing materials and assemblies as part of quality systems.


Precision and Bias If the liquid passes through the specimen, the material fails the test for resistance to penetration of the liquid. Procedure C uses a The purpose of the screen is to limit distention of the test specimen to 0.

Resistance to permeation and degradation should be determined by other test methods. However, it is possible that differences in chemical and molecular properties for example, surface tension lead to different results.

However, it is important that the selected retaining screen does not interfere with the observation of liquid penetration or affect the sealing of the specimen in the test cell.

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. Inadequate sealing of the specimen can lead to a false result observed liquid penetration that is due to the method of sealing rather than penetration through the specimen. Used for other speci?

For nonuniform samples, ff903 the lowest values. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Finished items and specimens are particularly important areas for testing as they consist of discontinuous and seamed regions of protective clothing.
