    The new ASTM C1860 test method provides for one testing apparatus to measure the tensile/bond strength of stucco: point loading by direct tension. The proposed revision includes another method to measure tensile strength by uniform negative pressure (vacuum). For ease of reference, the proposed text is placed within the test method language and highlighted in color and underline.
