Surface active agents — Determination of pH of aqueous solutions — Potentiometric method
The determination is carried out in the following way: Potentiometric measurement of the potential difference between a glass electrode and a reference electrode dipping in an aqueous solution of the sample. This method is only applicable when so indicated in the specific standard for each product.
Textile Test Methods Effect of Solvents on the Permanence of Textile
Finishes
This method describes a standard procedure for subjecting textile
materials to the action of solvents for the ultimate
determination, by the appropriate test method, of the effect of
such a treatment on the permanence of finishes added to improve
such functional properties as resistance to water, flame, insect
attack, etc.
Guide for the Selection and Use of Preferred Numbers
Provides guidance in the selection of preferred numbers for use
in standardization, rationalization, and size selection, leading
to a degree of variety control that would otherwise be difficult
or impossible. Preferred numbers are independent of any
measurement system and can, therefore, be used with metric or
yard/pound units, with currencies, with dimensionless numbers,
etc. This…
Textile Test Methods Standard Laundering Procedures

Textile Test Methods Grey Scale for Evaluating Change in Color
This method describes the Grey Scale for evaluating changes in
color of textiles in color fastness tests, and its use. A precise
colorimetric specification of the Scale is given as a permanent
record against which working standards may be compared.
Textile Test Methods Grey Scale for Evaluating Staining
This method describes the Grey Scale for evaluating staining of
undyed textiles in color fastness tests, and its use. A precise
colorimetric specification of the Scale is given as a permanent
record against which working standards may be compared.
Aluminum Alloy 1350 Round Wire, All Tempers, for Electrical Purposes
1. Scope
1.1 This Standard covers the electrical and mechanical characteristics of aluminum alloy 1350 round wire in the annealed, intermediate, and hard tempers for stranding into conductors or as solid single conductors, either bare or covered with a weather-resistant or insulating material.
Procedure for Measurement of the Maximum Exterior Sound Level of Stationary
Trucks with Governed D...
1. Scope
1.1 This Standard applies to trucks designed primarily for use on the road
and defines a procedure for measuring the maximum exterior sound level
emitted by trucks with governed diesel engines. The measurement is
made with the vehicle stationary and with the transmission in neutral.
1.2 The procedure defined in this Standard is primarily intended…
Relative density 60/60 degrees F hydrometers for general purposes
The requirements for five series of glass hydrometers concern reference levels for adjustment and reading, materials, dimensions, form, scale and handling. The annexes deal with standard surface tensions, stem diameters and meniscus corrections.
1. Scope
1.1 This Standard provides minimum requirements for mineral fibre, for use primarily in the insulation of dwellings and other heated building structures, and defines the types in current use. This Standard does not apply to preformed insulation less than 40 mm in thickness.
