C. DENSITY 6 INDICATIONS PER 100 SQ. IN.

3. THE TEST METHOD TO DETERMINE DIMENSIONAL STABILITY SHALL BE PERFORMED

AS FOLLOWS: THE TEST SPECIMENS (FINISHED PIECES) TESTED SHALL BE MEASURED

AT 23 +/- 3 DEG C (73 +/- 5 DEG F) AND PLACED IN A MINERAL OIL* BATH MAINTAINED AT 160 +/- 3 DEG C (320 +/- 5 DEG F). THE SPECIMENS SHALL REMAIN IN THE BATH FOR SIX

(6) HOURS AT TEMPERATURE AND ALLOWED TO SLOW COOL IN THE BATH AT A RATE

NOT TO EXCEED 23 +/- 3 DEG C (73 +/- 5 DEG F) PER HOUR. WHEN THE BATH REACHES

23 +/- 3 DEG C (73 +/- 5 DEG F), THE TEST SPECIMENS SHALL BE REMOVED AND MEASURED.

THE PERCENT CHANGE IN EACH DIMENSION, OUTSIDE DIAMETER, INSIDE DIAMETER,

AND THICKNESS, SHALL NOT BE GREATER THAN THE VALUE SPECIFIED. IN LIEU OF FINISHED PIECES FOR TEST SPECIMEN PREPARE A 1.5 IN. LONG SLICE (FULL DIAMETER) TO USE AS TEST SPECIMEN AND

TEST AS REQUIRED.
