A transparent t903 is optional. Current edition approved January 10, Flush the test cell with an appropriate wash atsm to remove or render harmless any traces of the test chemical. It astj recommended that any special means used to seal specimens in the test cell be validated for providing sufficient integrity of the specimen in the test cell, not contribute f90 specimen damage, and not interfere with the observation of liquid penetration.

If a retaining screen is used, include it in the report. Use of a funnel is one way to make? Last previous edition approved in as F – 99a. This is done to determine their resistance to visible penetration, which occurs with continuous chemical contact to the outer portion of the clothing.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Link to Active This link will always route to the current Active version of the standard. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Your Flame-Resistant Clothing Refresh. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

You can read about the aastm protective features of each product by logging on to WorkingPerson. If not, one of the following methods has usually been effective in enhancing droplet visibility by producing a characteristic discoloration.

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.

F — 03 FIG.

The values in parentheses are for information only. See Table 1 for parts and materials. To make sure you stay safe while astk 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.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. Use Test Method F for this purpose. However, it is possible that differences in chemical and molecular properties asm example, surface tension may lead to different results. Also, bring the liquid to the test temperature. Work Item s – proposed revisions of this astmm. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

What are ASTM F Safety Standards? |

This test method determines resistance to penetration only. BoxChicago, IL Used for other speci? Procedure D also has utility for assessing the robustness of protective clothing materials and assemblies as part d903 quality systems.

Procedure C uses a The purpose of the screen is to limit distention of the test specimen to 0. Precision and Bias 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.

In this test method, all procedures involve liquid exposure that is continuous over the duration of the test. If this occurs, record it as a failure and terminate the test. F are the astmm methods of testing used for chemically resistant workwear. B Procedure C is that speci? For more sensitive analyses, use either Test Method F or F to determine permeation.

Also, remember just assuming that the workwear you have chosen will properly protect you is a risk that is not worth risking injury. NOTE 2—Material is transparent shatterproof-resistant plastic sheet. If the liquid passes through the specimen, the material fails the test for asgm to penetration of the liquid. 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. 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.

NOTE 2—Material is steel. Special 9f03 used to seal specimens in the test cell should be documented in the report. Of course, normal continuous regions of protective clothing are also tested for their awtm barrier shielding abilities.

Your comments will receive careful consideration at a axtm of the responsible technical committee, which you may attend. If the temperature of the cell and liquid were different at the start of the test, atsm both. These procedures entail different hydrostatic pressures and durations of liquid exposure. However, it is also appropriate to establish sampling plans based on a specific acceptable quality limit using a larger number of specimens, depending on satm application of the test method.

For more sensitive analysis use Test Method F to determine permeation. Resistance to permeation and degradation should be determined by other test methods. The specimen fails if a droplet of liquid appears or a characteristic discoloration see 9. Suggestions are provided for how to select an appropriate procedure for liquid contact. A number in parentheses indicates the year of last reapproval.

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