Designation:

This standard is issued under the ﬁxed designation F316; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (ε) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1

These test methods cover the determination of two of the pore size properties of membrane ﬁlters with maximum pore sizes from 0.1 to 15.0 µm.

1.2

Test Method A presents a test method for measuring the maximum limiting pore diameter of nonﬁbrous membranes. The limiting diameter is the diameter of a circle having the same area as the smallest section of a given pore (Fig. 1).

1.3

Test Method B measures the relative abundance of a speciﬁed pore size in a membrane, deﬁned in terms of the limiting diameter.

1.4

The analyst should be aware that adequate collaborative data for bias statements as required by Practice D2777 is not provided. See the precision and bias section for details.

1.5

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6

This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

1.7

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
