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.

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 safety standards associated f9003 the chemicals you are working with or the standards that your employer sets. A transparent cover is optional. 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.

Resistance to permeation astn degradation should be determined by other test methods. 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 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, and degradation. Work Item s – proposed revisions of this standard.

If the temperature of the cell and liquid were different at the start of the test, report both. Random specimens shall be generated as described in Practice E A superscript epsilon e indicates an editorial change since the last revision or reapproval.


If this occurs, record it as a failure and terminate the test. Specific hazards are given in Section 7. 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.

B Procedure C is that speci? If not, one of the following methods has usually been effective in enhancing droplet visibility by producing a characteristic discoloration. NOTE 2—Material is aluminum.

Examples of retaining screens are 11 by 11 nylon screen, 14 by 14 polypropylene screen, and 13 by 13 polyester screen. Areas such as hands, legs, eyes, face and torso should be completely protected.

The purpose of the screen is to limit distention of the test specimen to 0. Used for other speci? 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. The deleterious effects of these chemicals can range from acute trauma such as f93 irritation and burn to chronic degenerative disease, such as cancer.

With the test cell vertically oriented, allowing the air to vent, carefully,? Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such astn, are entirely their own responsibility.

Link to Active This link will always route to the current Active version of the standard. NOTE 2—Material is steel. This is therefore considered a general failure point. If this occurs, record the failure, and terminate the test. If a retaining screen is used, include it in the report. These procedures entail different hydrostatic pressures and durations of liquid exposure.


Test specimens of protective clothing are exposed to a variety of chemical and molecular properties. A transparent cover see Fig.

A Use of a retaining screen is optional. Originally approved in Flush the test cell with an appropriate wash liquid to remove or render harmless any traces of the test chemical. 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.

What are ASTM F903 Safety Standards?

In this test method, all procedures involve liquid exposure that is continuous over the duration of the test. Of course, normal continuous regions of protective clothing are also tested for their effective barrier shielding abilities. 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.

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. F — 03 FIG. Use of a funnel is one way to make?
