SAE J365:2020 pdf free.(R) Method of Testing Resistance to Scuffing of Trim Materials
Positioned on the left side of the specimen holder, the scuff fixture holds the scuff head at a 1 10 degrees±1 degree angle with the vertical centerline of the scuff head located in a horizontal alignment and 32 mm from the specimen holder threaded post as shown in Figure 1. A weight applies a known mass to the scuff head tip.
Scuff head Type A is utilized and 0.9 kg mass is applied to the scuff head tip, unless otherwise agreed upon by the interested parties. The scuff head tip shown in Figure 2 shall be frequently checked for dimensions and replaced if found to deviate from the specified tolerances.
NOTE: The scuff fixture is used in place of abrasive wheels.
NOTE: The abrader vacuum system is not utilized during the scuff test.
a. Prepare a specimen approximately 130 mm diameter with a 6.5 mm center hole.
b. Place the specimen on the rubber pad of the specimen holder then secure the specimen using the 54 mm OD clamp plate and clamping nut.
c. Press the hold-down ring over the test specimen so that the material is drawn taut over the specimen holder with no wrinkles or bulges. Tighten the hold-down ring adjusting screw without causing the specimen to wrinkle or bulge.
Observe and report scuff resistance by comparing the test specimen to an approved master scuff specimen established by the interested parties, or as required by the applicable engineering specification. Report any deviation from the procedure.A change bar (l) located in the left margin is for the convenience of the user in locating areas where technical revisions, not editorial changes, have been made to the previous issue of this document.
