The resultsdetermine compliance with the applicable specifications, orthey can be used for comparative analysis.3.2 The

10、test methods apply to “as manufactured” materialand may not apply to material that has been weathered or ispast the manufacturers recommended shelf life.4. Sampling4.1 From each shipment or fraction thereof, select at randoma number of rolls equal to one half the cube root of the totalnumber rolls o

For convenience,a table showing the number of rolls to be selected from the lotsof various sizes is given in Test Method D146/D146M.4.2 The minimum sample shall consist of five rolls. Therolls so selected

12、constitute the representative sample used forall subsequent observations and tests pertaining to the lot ofmaterial being tested.4.3 When mutually agreed upon by the concerned parties,other sampling frequencies may be used and reported withinthe framework of these procedures.5. Adhesion to Plywood5.
