Sampling and Gaging Kit Operation (See Figure 2-17).  This kit is completely portable and self-contained.  It consists of a carrying case, which is divided into sections to hold the major items of equipment, a weighted beaker sampler (1), hydrometer cylinder (2), standard hydrometers (3), a cup case thermometer (4), gasoline and water indicating paste (5), an API gravity computer (6), and a innage tape and bob (7). Setting the Kit Up for Operation. (1) Clean innage tape (7) with cheesecloth.  Ensure equipment is clean, dry, and free of dirt. (2) Check mercury columns in hydrometer and cup case thermometer (4).  If mercury column is separated or glass cracked, replace instrument. (3) Check cup case thermometer (4) readings with other thermometers in area to ensure they read the same. (4) Before a product is sampled or gaged, rinse containers with same type of product to be sampled or gaged.

(5) Conduct tests in accordance with pamphlets stored in packet of case, which contain ASTM test methods. b. Anti-Icing Additive Test Kit Operation (See Figure 2-18).  The kit is portable and self-contained.  It consists of a carrying case, separatory funnel (1), support base (2) with rod and ring (3), refractometer (4), aluminum dishes, piston pipets, a graduated cylinder and a bottle with screw cap. Anti-Icing Additive Test Kit Setup and Operation. (1) Using a clean, dry container, obtain a 1-pint (0.473 l) sample of fuel to be tested. (2) Set up separatory funnel (1) with its support base (2), rod and ring (3). (3) Fill an aluminum dish one half full of water. (4) Using a graduated cylinder, transfer exactly 160 ml of fuel from step (1), to separatory funnel. (5) Using a piston pipet, add exactly 2 ml of water from aluminum dish to separatory funnel.  Cap funnel and shake vigorously for 3 minutes.  Place separatory funnel (1) in support stand. NOTE Refractometer should be treated as an optical instrument. (6) Open cover of refractometer (4) window.  Ensure window is clean.
