This standard specifies the terms and definitions, basic requirements, product requirements, test methods, inspection rules, marking, packaging, transportation and storage, and quality commitment of single crystal wafers. This standard applies to single crystal wafers such as artificial quartz (QZ), lithium niobate (LN), lithium tantalate (LT), lithium tetraborate (LBO) and lanthanum gallium silicate (LGS). These single crystal wafers are used as substrate materials for surface acoustic wave (SAW) devices.
