NOTE 2—Material is transparent shatterproof-resistant plastic sheet. NOTE 2—Material is aluminum. A superscript epsilon e indicates an editorial change since the last revision or reapproval. 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.

F — 03 FIG. Use Test Method F03 for this purpose. 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. A transparent cover see Fig.

This test method determines resistance to penetration only. This is therefore considered a general failure point.

If this occurs, record the failure, and terminate the test. The specimen fails if a droplet of liquid appears or a characteristic discoloration see 9. Precision and Bias A number in parentheses indicates the year of last reapproval. 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, and f93.

Test specimens of protective clothing are exposed to a variety of chemical and molecular properties. Aetm are the standard methods of testing used for chemically resistant workwear. Historical Version s – view previous versions of standard. See Table 1 for parts and materials.

B Procedure C is that speci? Your comments will receive careful consideration at a aetm of the responsible technical committee, which you may attend. Of course, normal continuous regions of protective clothing are also tested for their effective barrier shielding abilities.

What are ASTM F Safety Standards? |

Resistance to permeation and degradation should be determined by other test methods. Summary of Test Method 4.

Procedure D also has utility for assessing the robustness of protective clothing materials and assemblies as part of quality systems.

If a retaining screen is used, include it in the report. BoxChicago, IL If the temperature of the cell and liquid were different at f93 start of the test, report both. Work Item s – proposed revisions of this standard.

What are ASTM F903 Safety Standards?

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. It is asfm to note that the ASTM F standard testing does not apply to the crotch area or the finger tip areas of gloves. 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.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? For more sensitive analysis use Test Method F to determine permeation.
