Unless otherwise specified herein, all equipment, materials and articles incorporated in the products covered by this specification shall be new and shall be fabricated using materials produced from recovered materials to the maximu
14、m extent practicable without jeopardizing the intended use. The term “recovered materials means materials which have been collected or recovered from solid waste and reprocessed to become a source of raw materials, as opposed to virgin raw materials.

The case shall be fabricated of wood, plastic, or metal, and shall be provided wma hinged fitted cover and a positive fastener which securely fastens the cover to the case.
16、The case shall be approximately 100 mm by 100 mm by 200 mm in size, The case shall rest securely on a flat surface. for pH andxmatePdeterminations, situated on either side of a sample viewing cell. The solid transparent standards shall be fabricated of sheets of colored transparent material. The com
17、parator may be a separate unit or an integral part of the case, and the viewing cell may be a separate unit or an integral part of the comparator. The comparator, if separate from the case, shall resist upsetting or tipping. The maximum and minimum color standards for the pH determination shall repr

When the test kit has separate sampl
20、e tubes for use in the viewing cell, a total of three such tubes shall be provided to allow for breakage, 25 milliliters (mL) of pH indicator solution. The bottle shall be made of an amber tinting or low actinic glass, suitable for protecting the light sensitive solution. A liter (L) (1000 mL) of in

The indicator dyes shall be weighed accurately and diluted with 525 mL of pure 95 percent (190 proof
22、) elthyl alcohol (C2H50H). A 1 Normal (1N) potas- sium hydroxide solution shall be added dropwise until the color is green or blue. The in- dicator solution shall be mixed thoroughly and allowed to stand until all the dyes are completely dissolved. The indicator solution shall be diluted to 1 L with
23、 distilled water. The indicator solution shall then be adjusted to a green color by adding 1N potassium hydroxide dropwise if the solution is yellow, or 1N hydrochloric acid dropwise, if the solution is blue. When tested in accordance with 4.8.3, the indicator shall produce a color change from yello
