Standard Test Method for Measurement of Roll Wave Optical Distortion in Heat-Treated Flat Glass

Importancia y uso:

5.1 This test method is a procedure for determining the peak-to-valley depth and the wavelength of roll wave in flat glass and then calculating the optical distortion resulting from that roll wave. Peak-to-valley measurements provide a means of monitoring the roll wave distortion in a heat processed glass product.

5.2 Measured peak-to-valley depth provides information required by some specifiers of heat-treated glass products.

5.3 Roll wave is inherent in flat glass which has been heat treated in a furnace in which rollers are used to convey the glass.

5.4 Consult Specifications C1036 and C1048 for additional glass characteristics and quality information.
