Criteria for test method 1 (Chapter 10):

1. Fragments or residues of specimens that fall to the floor of the test chamber shall not continue to burn

for more than an average of 2 seconds per specimen for the sample of 10 specimens. 2. The average weight loss of the 10 specimens in a sample shall be 40 percent or less.

3. No individual specimen's percent mass loss shall deviate more than 3 standard deviations from the

mean for the 10 specimens.

4. When a retest is required, no individual specimen's percent mass loss in the second set of specimens

shall deviate from the mean value by more than 3 standard deviations calculated for the second set.

5. When a sample does not demonstrate passing performance in accordance with all of the conditions

indicated above, the material shall be recorded as having failed Test Method 1.

 Statement: This declaration of conformity is only based on the result of this laboratory activity, the impact of

the uncertainty of the results was not included.
