ASTM C1651 Roll Wave Distortion measurement in Heat-Treated Flat Glass

The standard method ASTM C1651 measures roll wave optical distortion in Architectural Glass. The peak-to-valley depth an d peak-to-peak distances can be used to determine roll wave distortion in flat, heat-treated architectural glass. Values in inch-pound units are used as standard.... Read More

    Scope:

    The standard method ASTM C1651 helps determine the peak-to-valley depth and the wavelength of a roll wave in flat glass which then helps in selecting the optical distortion resulting from that rolling wave. Peak-to-valley measurements provide a way of monitoring the roll wave distortion which occurs in flat, heat-treated architectural glass substrates processed in a heat processing continuous or heat-treated furnace in which rollers are used to convey the glass.

    Test Procedure:

    The test method ASTM C1651 comprises relocating an instrument across the glass surface parallel to the direction that the glass substrate traveled during heat processing. The device will predominantly measure the glass surface’s out-of-plane deformation, which is a characteristic of the glass and is known as “roll wave”. The peak-to-valley depths of the roll waves, W, and the peak-to-peak distances, L, are measured.

    The instruments are used in two methods named as:

    • Procedure A – Measuring with a Flat Bottom Gauge
    • Procedure B – Measuring with a “Three Point Contact” Gauge

    Specimen Size

    Following is the specimen size for ASTM C1651:

    Flat bottom plate Length ≥ 12 inches (305 mm).

    Flat bottom plate width  ≥ 2 inches (50.8 mm).

    Data:

    The following data is calculated for ASTM C1651:

    Distance of peaks = P1,P2,….Pn
    Distance to valley = V1, V2,….Vm

    Conclusion:

    The standard method ASTM C1651 measures roll wave optical distortion in Architectural Glass.
