1. Scope
1.1* This Standard applies to insulated conductors intended for use as leads
of transformers, motors, ballasts, solenoids, etc, where the baking temperature
of the windings, coils, etc, to which they are attached will not exceed 150°C,
except for the Type CL 1250 series where the maximum baking temperature will
not exceed 160°C, for Types CL1502 and CL 1503 where the maximum…
1. Scope
1.1 This Standard applies to stationary, electrically heated, warm air,
central furnaces of the forced-air type that discharge air into ducts extending
not less than 30 inches downstream from the heater elements, for use on nominal
system voltages of 600 V and less, designed to be used in non-hazardous
locations in household, commercial, and industrial applications, in accordance…

Statistical interpretation of test results — Estimation of the mean — Confidence interval
Concerns the estimation of the mean of a normal population on the basis of a series of tests applied to a random sample of individuals drawn from this population when the variance of the population is unknown and calculation of the conficence interval for the population mean therefrom and from the standard deviation. Test method may be subject to systematic errors.
Standardizes arc furnace test conditions and methods to determine the main parameters and technical operating characteristics.
Applies to industrial three-phase direct arc furnaces, the rated capacity of which is equal to or greater than 0.5 tonne. Also applies to furnaces having one or more electrodes, other than three-phase furnaces.
Density meters utilizing ionizing radiation. Definitions and test methods
Lays down definitions and test methods for density meters utilizing ionizing radiation designed for the measurement of the average density of liquids, slurries or fluidized solids. This standard applies to transmission type instruments only. Safety aspects are not included.
Measurements and test methods for 32 kHz quartz crystal units for wrist watches and standard values
Applies to 32 kHz quartz crystal units for wrist watches. Gives methods of measurement of resonance frequency, resonance resistance, frequency-temperature dependence and frequency pulling. Lays down test methods in accordance with IEC 68-2-6, 68-2-20, 68-2-21 and 68-2-27.
1. SCOPE
1.1 This standard applies to metric squares used by carpenters in determining
angles when fabricating parts from wood or other materials. Squares in
accordance with this standard shall be graduated with the International System
of Measurement (SI) Units. This standard will eventually supersede Imperial
graduated carpenter's squares now covered by CGSB 39-GP-21.
Characteristics of string insulator units of the long rod type
