each 5000 kg (10 000 lb) or fraction thereof. Approximately 50 g (0.02(1.76 oz) of dry glass spheres are required for each test.
This specimen is also selected by quartering or riffling.
NOTE 2—The quartering procedure for reducing bulk samples, to obtain representative test samples of suitable size, is described and illustrated in
Practice D346. Various types of riffle samplers are illustrated in Practice D2013.
7. Procedure
7.1 Hand Sieving:
7.1.1 Dry the specimen to substantially constant weight at a temperature of 105 to 110 °C.
7.1.2 Weigh 50 g of the dried glass spheres to the nearest 0.1 g and place on the sieve with the largest opening in the series
specified for the test, which shall be thoroughly dry. Hold the sieve, with pan and cover attached, in one hand in a slightly inclined
position so that the specimen will be well distributed over the sieve, at the same time gently striking the side about 150 times per
minute against the palm of the other hand on the upstroke. Turn the sieve every 25 strokes about one sixth of a revolution in the
same direction. Continue the operation until not more than 0.05 g passes through the sieve in 1 min of continuous sieving. Each
time, before weighing the material passing through the sieve, tap the side of the sieve with the brush handle in order to remove
any material adhering to the wire cloth.
7.1.3 When the sieving has been finished, remove the cover of the sieve and carefully remove the residue remaining on the sieve
to a tared container. Invert the sieve over a piece of glazed white paper and clean the wire cloth by brushing the underside. Add
the material thus removed from the wire cloth to the residue removed from the sieve.
7.1.4 Weigh the portion of the specimen retained on the sieve to the nearest 0.1 g. Place the material passing through the largest
sieve on the sieve with the next smaller opening for the series selected for the sieve analysis. Continue sieving in a similar manner,
using successively each of the selected series of sieves in the order of decreasing size of opening, and recording the weight of that
portion of the specimen retained on each sieve.
7.1.5 Washers, slugs, or shot shall not be used on the sieves.
7.2 Machine Sieving:
7.2.1 Mechanical sieving devices may be used but the glass spheres shall not be rejected if they meet the specification
requirements when tested by the hand-sieving method described in 7.1. When mechanical sieving devices are used, their
thoroughness of sieving shall be tested by using the hand method for comparison.
8. Calculation
8.1 Calculate the weight of material and the percent of the specimen passing each of the sieves.
9. Report
9.1 Report the following information:
9.1.1 Results of the sieve analysis reported as the total percent passing each sieve, expressed to the nearest 0.5 %, and
9.1.2 The method of sieving used.
10. Precision and Bias
10.1 The precision of this test method is based on an interlaboratory study of Test Method D1214 for Sieve Analysis of Glass
Spheres conducted in 2008. Five laboratories participated in this study. Each of the labs reported triplicate test results for a single
material. Every “test result” reported represents an individual determination. Except for the use of data from only a single
laboratory, Practice E691 was followed for the design and analysis of the data; the details are given in ASTM Research Report
RR:D01-1150.
10.1.1 Repeatability Limit (r)—Two test results obtained within one laboratory shall be judged not equivalent if they differ by
more than the “r” value for that material; “r” is the interval representing the critical difference between two test results for the same
material, obtained by the same operator using the same equipment on the same day in the same laboratory.
10.1.1.1 Repeatability limits are listed in Tables 1-15.
10.1.2 Reproducibility Limit (R)—Two test results shall be judged not equivalent if they differ by more than the “R” value for
that material; “R” is the interval representing the critical difference between two test results for the same material, obtained by
different operators using different equipment in different laboratories.
10.1.2.1 Reproducibility limits are listed in Tables 1-15.
10.1.3 The above terms (repeatability limit and reproducibility limit) are used as specified in Practice E177.
10.1.4 Any judgment in accordance with statement 10.1.2 would normally have an approximate 95 % probability of being
correct, however the precision statistics
