4. Description of Samples:

The sample was supplied, prepared and distributed by Nu-Wool Co. Below is a

list of the samples.

1. Cellulose Insulation - A

5. Interlaboratory Study Instructions

RR: C16-1037

- 3 -

Laboratory participants were emailed the test program instructions. For a copy of

the instructions, please see Annex A.

6. Description of Equipment/Apparatus1:

For information on the equipment/apparatus used by each laboratory, please see

Annex B.

7. Data Report Forms:

Each laboratory was provided with a data report form for the collection of data. A

copy of the data is provided in Annex C.

Please note: The laboratories have been randomly coded and cannot be

identified herein.

8. Statistical Data Summary:

A summary of the statistics calculated from the data returned by the participating

laboratories is provided in Annex D.

9. Precision and Bias Statement:

9.1 The precision of this test method is based on an interlaboratory study

of C739, Standard Specification for Cellulosic Fiber Loose-Fill Thermal

Insulation, conducted in 2009. Six laboratories participated in this study,

reporting the Design Density for a single cellulose insulation. All six labs

reported results in pounds per cubic foot. A total of 16 replicates were

reported by the participants for each of the unit measurements. Every

“test result” reported represents an individual determination. Except for the

use of data from only a single type of cellulosic insulation, Practice E691

was followed for the design and analysis of the data; the details are given

in ASTM Research Report No. C16-1037.i

9.1.1 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.

9.1.1.1 Repeatability limits are listed in Table 1 below.

9.1.2 Reproducibility limit (R) - Two test results shall be judged not

equivalent if they differ by more than the “R” value for that material; “R”

1 The equipment listed was used to develop a precision statement for C0739-11. This listing is not an
