Core Sampling of Raw Wool in Packages for Determination
of Percentage of Clean Wool Fiber Present1
This standard is issued under the fixed designation D1060; 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.

D4845 Terminology Relating to Wool

1. Scope
1.1 This practice for sampling covers a procedure for
obtaining samples from lots of grease, pulled, or scoured wool
or related animal fibers in bales or bags for the determination
of the clean wool fiber present by a procedure similar to that
described in Test Method D584.

3. Terminology
3.1 For all terminology relating to D13.13, Wool and Wool
Felt, refer to Terminology D4845.
3.1.1 The following terms are relevant to this standard:
clean wool fiber present, core and raw wool.

1.2 This practice provides a description of suitable core
sampling equipment, the sampling procedure, and the method
for determining the number of packages to be bored and the
number of cores to be taken from each sampled package.

3.2 For definitions of other textile terms used in this

practice, refer to Terminology D123.

1.3 Reliable estimates are given for the standard deviation
of the percentage clean wool fiber present between packages
and within packages for lots of many types of raw wool.

4. Summary of Practices
4.1 The lot is core sampled in accordance with one of a
series of equivalent schedules based on estimates of variability
of the percentage clean wool fiber present and on the required
level of precision. A set of packages of wool is taken as a lot
sample. From each package in the lot sample, a fixed number
of cores of wool is drawn to be used as a laboratory sample.
Guidance in the selection of the most economical of the
equivalent schedules is provided.

1.4 The values stated in inch-pound units are to be regarded
as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only
and are not considered standard.
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 and health practices and determine the applicability of regulatory limitations prior to use.

5. Significance and Use
5.1 Core sampling is widely accepted, when applicable, for
obtaining a laboratory sample representative of the clean wool
fiber present in a lot of packaged raw wool.

5.2 If the wool is so loosely packed that a core cannot be
cut, or if it is so highly compressed that the sampling tool
cannot readily penetrate into the package to the required depth
and in the required direction, core sampling is not applicable.
The density of wool in most types of commercial packages is
suitable for sampling by this method.
5.3 The procedure described in this practice is adapted to
the application of statistical methods for estimating the size of
sample required to achieve a required level of sample precision
at minimum cost.

NOTE 1—The basic sampling equipment, operating procedure, and
statistical approach used in this practice have been adapted for sampling
lots of wool for the determination of other properties that are not affected
by boring, such as average fiber diameter, and for sampling lots of other
bulk fibers in packages.

(Metric equivalents may be calculated by multiplying inches by 25.4 to obtain equivalent dimensions in millimetres.)

FIG. 1 Small Diameter Wool Sampling Tool (United States Customs Service)

6.2 Sample Container—A container with closure of such
material and so constructed that a sample stored therein will
not show a material change in its moisture content during the
interval between sampling and weighing the sample for test.

6. Apparatus
3

6.1 Sampling Tool —A tube equipped with a cutting edge,
together with a drill, hammer, press, or similar device, and
accessories. The tube must be capable of penetrating the

required distance (see 7.2) into a package of wool and cutting
a core therefrom, which core must be retained substantially
unchanged within the tube during its withdrawal from a
package.
6.1.1 Fig. 1 illustrates the design of a recommended type of
rotatable small-diameter wool sampling tube.
6.1.2 Sampling tubes in common use range from approximately 1⁄2 to 2 in. (13 to 50 mm) in diameter, and from 10 to
40 in. (250 to 1000 mm) in length.
6.1.3 Some types of sampling tubes are equipped with
receptacles at the rear of the tube.
6.1.4 Drills of 1⁄2 hp (375 w) rotating at 200 to 550 rpm (3.3
to 10 rps), have been found to be satisfactory.
6.1.5 A toothed cutting edge on a rotating tube of small
diameter, instead of the smooth edge illustrated in Fig. 1, is
acceptable provided that for any specific design it has been
shown that a bias is not introduced thereby. The absence of bias
in samples obtained with a rotating 2-in. (50 mm) diameter
tube with a toothed cutting edge has been demonstrated.

7. Sampling Procedure
7.1 Time of Sampling—Take the sample at or about the time
the lot is weighed.
7.2 Depth of Penetration—Penetrate a bale of wool with the
sampling tube to a depth such that substantially all parts of the
package can be reached. Maintain the same depth of penetration for each core taken from a given lot.
7.3 Location of Borings:
7.3.1 Consider a package as composed of eight sections
approximately equal in volume, defined by top or bottom, front
or back, left or right.
7.3.2 Alternate the location of boring in such a fashion that

the total composite sample will consist of approximately the
same number of cores from each section of the packages.
7.3.3 If the packages have been compressed in a baling
press, enter a package through a compression surface and in a
direction normal to that surface.
7.4 Whenever there is danger that loose sand or other
material may drop out of the tube during or after boring, so
position the package that the direction of boring will be
horizontal.

The sole source of supply of the apparatus known to the committee at this time
is Yocom-McColl Testing Laboratories, Inc., 540 Elk Place, Denver, CO 80216. If
you are aware of alternative suppliers, please provide this information to ASTM
Headquarters. Your comments will receive careful consideration at a meeting of the
responsible technical committee,1 which you may attend.

7.5 Just before entering a sampling tube into a package of
wool, cut the covering in such a way that none of the covering
material fibers become mixed with the core or with the wool in
the package.

8.2.1 Reliable Estimates of Variances Available—When reliable estimates of σb2 and σw2 are available, determine the
required number of packages based on a specific number of

cores per package using Eq 2 or Table 1:

7.6 Immediately upon withdrawal of the tube after boring,
extrude the core directly into the sample container or the
intermediate receptacle (6.1.3) without loss of material or
unnecessary exposure to atmospheric conditions that may
result in a change in the moisture content of the core.

8.1 Variance of Sample Mean—If a sample consists of k
cores from each of n packages from a lot of N packages of raw
wool, and the n × k cores are composited into a single sample
on which m tests for percent clean wool fiber present are made,
then the variance of the mean of the observations is given using
Eq 1 (Notes 2 and 3):

where:

= number of cores to be taken from each selected
package (Note 5),
= reliable estimate of the standard deviation for

NOTE 5—Any convenient value of k may be used, but the value of k
calculated using Eq 3 and rounding to the nearest whole number will give
the most economical sample:

where:
σx2 = variance of the mean of the m observations,
σb2 = variance for percent clean wool fiber present between
packages within the lot,
σw2 = average variance for percent clean wool fiber present
of cores within packages of the lot,
σt2 = variance of observations on a homogeneous sample,
σs2 = variance for percent clean wool fiber present for the
sample, as defined by Eq 1,
n
= number of packages selected at random from the lot
from which cores are taken,
N
= number of packages in the lot,
k
= number of cores taken from each of the n packages,
and
m
= number of observations made on the composite
sample.

(3)

where:
B = average cost of selecting and positioning a package for coring,
and
C = average cost of taking and handling a core, and the other terms are
defined in the legend for Eq 2.
NOTE 6—Estimates of the variances are best based on data obtained in
investigations using analysis of variance techniques for lots of similar
packaged raw wool. The estimates listed in Table A1.1 were so obtained.
Estimates may also be based on records in the user’s laboratory if the plan
for sampling and testing described in STP 1145 has been followed. For
testing that does not involve a dispute between the purchaser and the
supplier, variances may be estimated as specified in Practice E122.

8.2.2 No Reliable Estimates of Variances Available—When
no reliable estimates of σb2 and σw2 are available, determine the
required number of packages based on a specific number of
cores per package using Eq 2 or Table 1 and sw = sb = 5.0
percentage points. These estimates of variability are somewhat
larger than the variability usually found in practice and will
usually require a larger number of cores than when reliable
estimates of variability are available.

NOTE 2—Uniform mass of packages and of cores are assumed. If the
departure from uniformity is such that a material error would be
introduced by this assumption, proportional compositing must be adhered
to.
NOTE 3—The factor (N-n)/N is the correction for sampling from a finite
population. A corresponding correction is generally not necessary for
cores and tests.

8.2 Number of Cores—Unless otherwise agreed upon, as
when specified in an applicable material specification, take a
number of cores such that σs2 will be 0.2603.

9. Sampling Schedules
9.1 For convenience, Table 1 gives the values of n calculated by Eq 2 for selected pairs of values of sw and sb and for
selected lot sizes, N, and numbers of cores per package, k, for
an allowable variation of 61.0 % clean wool fiber present at a
probability level of 95 %.

NOTE 4—0.2603 is the value calculated from (1.0/1.960)2
where:
1.0
= allowable variation of the percent clean wool fiber present of
the composite sample, and

ANNEX
(Mandatory Information)
A1. CLASSIFICATION OF WOOLS FOR SAMPLING PURPOSES

A1.1 Committee studies have shown that the values for sw
and sb listed in Table A1.1 are good estimates of the average
values for lots of several types of packaged wool as they
appeared in the commerce of the United States of America
early in 1964, provided the packages comprising the lot
conformed to the following conditions:

A1.1.3 All packages contained the same kind of wool or
hair (sheep, goat, camel, alpaca, and so forth), from the same
geographic area, of the same general character (apparel or
carpet type, fleece, matchings, crutchings, and so forth), and in
the same general condition (grease, scoured, washed, pulled,
and so forth).

A1.1.1 Each package was uniformly and randomly packed.

NOTE A1.1—The data given in Table A1.1 would not be applicable to
lots containing packages materially damaged by water, oil, or other agent
unless these packages were first removed from the lot for separate
evaluation. Normally soiled or torn coverings of themselves do not
indicate material damage for sampling purposes.

A1.1.2 All packages were undamaged (Note A1.1), of the
same kind (bales or bags), and of approximately the same

dimensions and mass, within usual commercial limits.
