1、Designation: F2053 00 (Reapproved 2011)Standard Guide forDocumenting the Results of Airborne Particle PenetrationTesting of Protective Clothing Materials1This standard is issued under the fixed designation F2053; the number immediately following the designation indicates the year oforiginal adoption
2、 or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONWhile test methods exist to measure penetration of airborne particles throug
3、h barrier specimens, thedata are not reported in a standard fashion. To be useful, such data should be combined withinformation that characterizes the test method employed. This information includes descriptions of testmaterials, challenge particles, test apparatus, methods used to count and measure
4、 the particles and testparameters such as flow rate, pressure drop, humidity, and temperature. The flow rate, pressure drop,particle size, and detection limits are of particular importance when comparing data from differentsources during the selection of protective clothing. Some reports on particle
5、 barrier testing do notinclude such specificity. This guide provides a standard format for recording important test parameterinformation and data. The standard format is intended to facilitate the use of electronic databases tostore, retrieve, and apply test results.1. Scope1.1 This guide provides a
6、 format for documenting informa-tion and performance data for a airborne particle penetrationtest.1.2 Documented data and information are grouped into fivecategories that define important aspects of each test:1.2.1 Description of material tested,1.2.2 Challenge particles,1.2.3 Test method,1.2.4 Test
7、 results, and1.2.5 Source of the data.1.3 Use of this guide is facilitated by adherence to proce-dures outlined in a standard test method.1.4 The values stated in SI units are to be regarded asstandard. No other units of measurements are included in thisstandard.2. Significance and Use2.1 This guide
8、 is intended to encourage thorough andconsistent documentation of airborne particle penetration test-ing and its results.2.2 Uniform information and performance data increase thelikelihood of selecting proper particle protective clothing bydirect comparison of one material with another.2.3 A standar
9、d format for test information and data alsoencourages computer storage of test results for easy retrieval,comparison, and correlations.3. Data Fields3.1 The reporting format is shown in Fig. A1.1.3.2 If a particular field is not applicable to the testingperformed, insert “not applicable” in that fie
10、ld. If a particularpiece of data has not been obtained, insert “no data” or“unknown” in the field.3.3 A description of each field of information follows:3.3.1 Description of Material TestedIdentification of thespecific protective clothing material tested to facilitate futureidentification of the tes
