This record is applied for measuring wow and flutter based on DIN 45507(measuring equipment for frequency fluctuation) and DIN 45539 (measuring method). Measuring frequency recorded horizontally is 3150Hz. Record itself shall be manufactured within ±0.06% (unweighted ±0.12%) fluctuation of frequency. And wavy height change hindering optimal centering shall not exceed 0.3mm. The test record based on this standard was assigned to DGG.
