INTRODUCTION.
The operator should read the general water test
information (para 2-1), prior to using the WQAS.
(See fig. 1-2.)
a.
Instructions for using the kits are arranged alphabetically by
test kit title and are designed to be conducted with the following
principal equipment within the ranges specified.
(1) Alkalinity Test Kit Range O mg/l to 500 mg/l.
(2) Low range Chloride Test Kit Range O to 1500 mg/l.
(3) Color Test Ranges. Low:
O to 100 APHA platinum colbalt
units.
High:
O to 500 APHA platinum cobalt units.
(4) Comparator. Color, Hydrogen Ion and Residual Chlorine -
Chlorine Test - 0.1 to 10.0 ppm Wide range pH indicator - 3.0 to
11.0.

Water Testing Kit, NSN 6665-00-171-9747).
(Used in buys 1 and 2.)
(8) Sulfate Test Kit - Range O to 3000 mg/l.
(9) Turbidity Test Kit - Range of 5 to 100 JTU units in incre-
ments of 5 units and 10 to 200 JTU units in increments of 10 units.
(10) Water Testing Kit, Chemical agents, AN-M2, NSN 6665-00-
171-9747.
(Used in buys 1 and 2.)
(11) Water Testing Kit, Chemical Agents - M272, NSN 6665-01-
134-0885.
(Not used in buys 1 and 2).
b.
Accessory support items (lab-ware) for the kits are identified
in the test procedures with the stored location item member as given
on the WQAS - Engineer Loading Diagram (fig. 1-6).
c. See the Index under Test Procedures - Engineer for a complete
listing.
Each procedure is introduced with a brief chemical discus-
sion to familiarize the operator with the causes of the condition
followed by a step-by-step procedure to accomplish measurement, with
the pertinent kit, of the degree of the condition.
d.
Instructions for determination of chemical dosage requirements
are stored within the set.
