AOAC Official Method 937.08 Volume of Shucked Oysters, Clams, or Scallops
First Action 1937
Final Action
Fluff entire contents of commercial container, or container in which test sample is received (£3.8 L; 1 gal.), by pouring into standard measuring vessel through distance of 1 ft. ³30 cm, then pouring back into container from same height, and again pouring into measuring vessel. Use metal funnel (stainless steel preferable) 8–10 in. (20–25 cm) diameter at top, with stem 3 inc.(7.6 cm) diameter and ca 7.6 cm long, to facilitate pouring from one vessel to another. Measures are straight-side, cylindrical, made of metal (stainless steel preferable), holding exactly 1 gallon or 1 quart, respectively, and having smooth rims. Plane of rim must be level when measure is standing on level surface. Diameter of top of gallon measure is
4.25–5.25 in. (10.8–13.3 cm), and that of quart measure is 3.25–3.5in. (8.3–8.9 cm). Calibrate with standard glass measures, and for estimating volumes less than level full, use graduated mechanic’s depth gage to measure distance from rim to surface of contents. Tabulate depth gage readings against volumes or%shortages as desired for each measuring vessel. Measure head space with depth gage and determine volume. For £1 pint containers, calibrated glass cylinders may be used.
