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.
Specifies the objective criteria which make it possible to assess the value of the results obtained in each particular case. It is not intended to prescribe a type of apparatus or a procedure for converting the instrument response to concentrations units because of the broad range of equipment available and the difficulty of completely specifying all working conditions in a spectrographic…
Standard Tolerances for Linear Dimensions - Inch and Metric
1. Scope
1.1 This Standard gives tables of standard tolerances for linear dimensions in both inch and metric units, covering a range of sizes up to 200 inches or 5,000 millimetres. Tolerances are provided in a series of grades which cover the full range of precision, from ultra precise products such as gauging elements to coarse tolerances suitable for rough work, and for many types of…
