NOTE 2—Material is steel.
What are ASTM F903 Safety Standards?
For more sensitive analysis use Test Method F to determine permeation. If a retaining screen is used, include it in the report. The resistance to visible penetration of the test liquid is determined with the liquid in zstm contact with the normally outside surface of the test specimen.
Precision and Bias NOTE 2—Material is transparent shatterproof-resistant plastic sheet. A transparent cover see Fig.
This is therefore considered a general failure point. In this test method, all procedures involve liquid exposure that is continuous over the 9f03 of the test. BoxChicago, IL These procedures entail different hydrostatic pressures and durations of xstm exposure. The deleterious effects of these chemicals can range from acute trauma such as skin irritation and burn to chronic degenerative disease, such as cancer.
See Table 1 for parts and materials. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
You can read about the individual protective features of each product by logging on to WorkingPerson. Originally approved in F are the standard methods of testing used for chemically resistant workwear. Procedure C uses a A superscript epsilon e indicates an editorial change since the last revision or reapproval. This test method determines resistance asstm penetration only. For more sensitive analyses, use either Test Method F or F to determine permeation.
The purpose of the screen is to limit distention of the test specimen to 0. Work Item s – proposed revisions of this standard. Of course, normal continuous regions of protective clothing are also tested for their effective barrier shielding abilities. Finished items and specimens are particularly important areas for testing as they consist of discontinuous and seamed regions of protective clothing.

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. Aatm 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 safety standards associated with the chemicals you are working with or the standards that your employer sets.
Areas such as hands, legs, eyes, face and torso should be completely protected. Remove the specimen and gasket from the cell and discard. Suggestions are provided for how to select an appropriate procedure for liquid contact. A Use of a retaining screen is optional. Last previous edition approved in as F – 99a.
Resistance to xstm and degradation should be determined by other test methods. If not, one of the following methods has usually been effective in enhancing droplet visibility by producing a characteristic discoloration. Passing results indicate that no liquid penetration was observed over the duration of the test exposure.
Asym comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? 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.
Users of this standard are asfm advised that determination of the validity of any such patent rights, and the risk of asym of such rights, are entirely their own responsibility.
If the temperature of the cell and liquid were different at the start of the test, report both. Link to Active This link will always route to the current Active version of the standard. 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.
The values in parentheses are for information only. Since engineering controls may not eliminate all possible exposures, attention is often placed on reducing the potential for direct skin contact through the use of protective clothing that resists permeation, penetration, astj degradation.
Test specimens of protective clothing are exposed to a variety of chemical and molecular properties.
Individual reprints single or multiple copies f90 this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
Your Flame-Resistant Clothing Refresh. Examples of retaining screens are 11 by 11 nylon screen, 14 by 14 polypropylene screen, and 13 by 13 polyester screen.
The values in parentheses are for information only. 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.
If this occurs, record the failure, and terminate the test.

This is done to determine their resistance to visible penetration, which occurs with continuous chemical contact to the outer portion of the clothing. Flush the test cell with an appropriate wash liquid to remove or render harmless any traces of the test chemical.
A number in parentheses indicates the year of last reapproval. With the test cell vertically oriented, allowing the air to vent, carefully,?
