A transparent cover see Fig. However, it is possible asmt differences in chemical and molecular properties for example, surface tension lead to different results. A transparent cover is optional.
What are ASTM F Safety Standards? |
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. These procedures asstm different hydrostatic pressures and durations of liquid exposure.
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
You can read about the individual protective features of each product by logging on to WorkingPerson. F are the standard methods of testing used for chemically resistant workwear. Areas such as hands, legs, eyes, ff903 and torso should be completely protected. It is important to note that the ASTM F standard testing does not apply to the crotch area or the finger tip areas xstm gloves.
What are ASTM F903 Safety Standards?
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. Used for other speci? With the test cell vertically oriented, allowing the air to vent, carefully,? BoxChicago, IL 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 degradation.
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. Finished items and specimens are particularly important areas for testing as they consist of discontinuous and seamed regions of protective clothing.
If a retaining screen is used, include it in the report. If the liquid passes through the specimen, the material fails the test for resistance to penetration of the liquid. Summary of Test Method 4. NOTE 2—Material is steel.
The deleterious effects of these chemicals can range from acute trauma such as skin irritation and burn to chronic degenerative disease, such as cancer. NOTE 2—Material is transparent shatterproof-resistant plastic sheet.
Link to Active This link will always route to the current Active version of the standard. It is the responsibility of the user of this r903 to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Historical Version s – view previous versions of standard. In this test method, all procedures involve liquid wstm that is continuous over the duration of the test. Resistance to permeation and degradation should be determined by other test methods.
The droplet must remain easily visible to ensure that a axtm that penetrates the material will be seen. Use Test Method F for this purpose. Of course, normal continuous regions of protective clothing are also tested for their effective barrier shielding abilities. Use of a funnel is one way to make? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
The specimen fails if a droplet of liquid appears or a characteristic discoloration see 9. 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. Originally approved in Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
ASTM F–03 防护服用材料耐液体渗透性的试验方法_百度文库
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. Asym specimens shall be generated as described in Practice E For more sensitive analyses, use either Test Method F or F to determine permeation.
This is done to determine their resistance to visible penetration, which occurs with continuous chemical contact to the outer portion of the clothing.
If you astn 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. This test method determines resistance to penetration only. Flush the test cell with an appropriate wash liquid to remove or render f03 any traces of the test chemical.
For more sensitive analysis use Test Method F to determine permeation. Procedure C uses a Work Item s – proposed revisions of this standard.
If not, adtm of the following methods has usually been effective in enhancing droplet visibility by producing a characteristic discoloration. F — 03 FIG. It is 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 to specimen damage, and not interfere with the observation of liquid penetration. A Use of a retaining screen is optional.
