ASTM D7707-21

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D7707 − 11 (Reapproved 2016) D7707 − 21
Standard Specification for
Wipe Sampling Materials for Beryllium in Surface Dust
This standard is issued under the fixed designation D7707; 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 (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This specification covers requirements for premoistened wipe materials that are used to collect settled dusts on surfaces for
the subsequent determination of beryllium.
1.2 For wipe materials used for the determination of lead in surface dust, refer to Specification E1792. This is mentioned to insure
that users of wipes recognize that there is some relationship between wipes and the analyte of interest.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This specification contains notes that are explanatory and are not part of the mandatory requirements of the specification.
1.5 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 safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use.
1.6 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.

E1792 Specification for Wipe Sampling Materials for Lead in Surface Dust
3. Terminology
3.1 For definitions of pertinent terms not listed here, see Terminology D1356.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 lot, n—a finite quantity of a given product manufactured under production conditions that are considered uniform.
3.2.2 standard beryllium test method, n—as used in this specification, any of the following test methods: D7035, D7202, D7439,
the graphite furnace atomic absorption technique in TestNIOSH Method E1613,7102, or a equivalent test method issued by a
national or international consensus standard organization.
3.2.3 wipe, n—a disposable towellette that is may or may not be premoistened with an acceptable agent.wetting agent, depending
on the intended application for obtaining beryllium samples.
3.2.3.1 Discussion—
The towellette is used to collect a sample of settled dust on a surface for subsequent beryllium analysis.
4. Significance and Use
4.1 This specification is intended for use by manufacturers and suppliers to evaluate the performance of wipe sampling materials
for beryllium in surface dust.
4.2 This specification may also be employed by users of wipes to compare the performance of candidate wipes for the sampling
of beryllium in surface dust.
5. Manufacture
5.1 The wipes shall be made from materials using methods that ensure compliance with the requirements of Sections 6 and 8, and
shall be clean and free of imperfections that would affect their performance.
5.2 An expiration date shall be established based on date of manufacture, and shall be marked on each package (see 10.2). The
expiration date should not be less than one year from date of manufacture.
6. General Requirements
6.1 Wipes shall conform to the requirements in 6.1.1 – 6.1.8. Test procedures for each requirement are found in Section 8.
6.1.1 Background Beryllium—The mean background beryllium content per wipe shall be less than 0.0005 μg.
6.1.2 Ruggedness—Wipes shall be sufficiently rugged so as to be capable to be used to wipe a 2000 cm area (large wipes; see
6.1.4.1(1)) or 500 cm area (small wipes; see 6.1.4.1(2)) of a vinyl or urethane-coated vinyl tile surface without tearing.
6.1.3 Moisture Content—Each wipe, when examined, must be fully wetted upon removal from the package or container. Wipes
shall have a moisture content such that the coefficient of variation for a random sampling of the lot of wipes be no greater than
25 % across individually packaged wipes, and 25 % within and between multi-packaged wipes.
6.1.4 Dimensions:
6.1.4.1 The mean area of the wipe shall be either:
2 2
(1) No smaller than 200 cm and no larger than 400 cm with the mean dimension of a side or diameter no smaller than 10
cm or larger than 20 cm (referred to as the “large wipe”); or,

D7707 − 21
2 2
(2) No smaller than 16 cm and no larger than 38 cm with the mean dimension of a side or diameter no smaller than 4.0 cm
or larger than 8.0 cm (referred to as the “small wipe”).
NOTE 1—Large wipes are intended for use on larger areas (for example, 1000 cm ). Small wipes are intended for use on smaller areas (for example, 100
cm ).
6.1.5 Thickness—Dry wipes (wipes without the moistening agent) shall have a mean thickness of at least 0.005 cm, but no greater
than 0.05 cm (see 8.6).
6.1.6 Mass—The coefficient of variation in mass of dry wipes in a lot shall not exceed 10 %.
6.1.7 Beryllium Recoveries—The mean beryllium recoveries from wipes spiked with Certified Reference Materials (CRMs) shall
be 100 6 20 % at the 95 % confidence l
