8.1.1.1 Warning—Chromic acid cleaning solution is corrosive to skin, eyes and mucous membranes and can cause severe burns. Avoid contact with eyes. skin or clothing. In making dilute solution, always add acid to water with care. Chromic acid cleaning solution is a strong oxidizer. Avoid contact with organic or reducing substances as a tire could results. See supplier’s Material Safety Data Sheet for further information. Other cleaners are much safer and may he equally effective.
8.1.2 Fill the container with reagent water conforming to Type II of Specification Dl 193 at a temperature somewhat below that specified. Cap the container, leaving the overflow orifice open. Immediately remove excess overflowed water or water held in depressions by wiping dry with absorbent material. Avoid occluding air bubbles in the container.
8.1.3 Bring the container and contents to the specified temperature using the conStant-temperature bath or room if necessary. This will cause further slight flow of water from the overflow orifice due to the expansion of the water with the rise of the temperature.
8.1.4 Remove the excess overflow by wiping carefully with absorbent material, avoiding wicking of water out of orifice, and immediately cap the overflow tube where such has been provided. Dry the outside of the container, if necessary, by wiping with absorbent material. Do not remove overflow that occurs subsequent to the first wiping after attainment of the desired temperature (Note 3). Immediately weigh the filled container to the nearest 0.001 % of its weight (Note 4). Record this weight, N, in grams.
Nom 3—Handling the container with bare hands will increase the temperature and cause more overflow from the overflow orifice, and will also leave fingerprints; hence, handling only with longs and with hands protected by clean, dry, absorbent material is recommended.
Nom 4—Immediate and rapid weighing of the tilled Container is recoinniended here to minimize loss of weight due to evaporation of the water through orifices, and from overflow subsequent to the first wiping after attainment of temperature where this overflow is not retained by a cap.
