ABSTRACT:
A holder is shown for flat specimens which are to be tested for the abrasion resistance of coatings or printed matter. In one embodiment, the holder is formed with block members with pads placed therebetween for reception of the specimens in face-to-face contact. The block members have curved surfaces at the ends to simulate the motion of transportation when utilized in conjunction with an abrasion testing machine. A retainer strap has flanges for engaging curved end portions of the blocks to aid in retaining them in contact. A method of testing flat specimens is also described.
