All test reports shall contain the individual values utilized in expressing the final result. For the finished knitted cloth, when furnished as piece goods, the lot size shall be expressed in units of one yard each and the sample size shall be in accordance with 4.4.1. The sample unit shall be 2 continuous yards full width except when the type I wool cloth subjected to a shrink resistant treatment is applicable 1/4 yard of the untreated material shall also be required for comparable purposes. For the finished cuffs and waistbands the lot size shall be expressed in units of one cuff or waistband each. With the exception of weight per dozen pair of cuffs, the sample size shall be in accordance with 4.4.1. The sample unit shall be as follows:

Cuffs, wrist and ankle.

Weight determination - One dozen (12) pairs of cuffs in one size, with a sample size of one (1) regardless of lot size.

All remaining test characteristics - Six (6) individual cuffs except when the type I wool cuffs subjected to a shrink resistant treatment are applicable, three (3) untreated cuffs shall also be required for comparable purposes.

Waistbands.

Six (6) individual cuffs except when the type I wool cuffs subjected to a shrink resistant treatment are applicable, three (3) untreated cuffs shall also be required for comparable purposes.

The lot shall be unacceptable if one or more sample units fail to meet any requirement specified.

1/ On the color transfer cloth, only the stain on the wool, polyester or the fiylonfiber, whichever is applicable, shall be evaluated.

~/ Except that the contractor’s submission shall be compared with the standard sample or rated adjectively after exposure of 6 standard fading hours.

3/ The specimens must be dried after each of the three laundering cycles.

~/ Three treated and three untreated specimens per sample unit.

s/ One determination shall be performed per sample unit and the results =eported as “pass” or “fail”.

6/ For type I, class 4 cloth, do not press specimens prior to measuring ~imensional stability.

4.5.1 Determination of weight per dozen. Twelve (12) pairs of the types I, III and IV ankle or wrist cuffs as applicable, shall be allowed to reach equilibrium under standard conditions as defined in F13D-STD-191.When under standard conditions, the cuffs shall be weighed as a unit to the nearest 1.0 ounce. The entire lot shall be rejected if the weight per dozen is below the minimum weight specified in Table I.

* 4.5.2 Spectral reflectance test. Spectral reflectance data shall be obtained from 600-860 nm relative to a barium sulfate standard, the preferred white reference standard. Other reference white standards may be used-,provided they are calibrated to an absolute white; i.e., Halon, magn-esiumoxide-or vitrolite tile. The spectral band width at 860 nm shall be less than 26 nm. Reflectance measurement; may be made either the monochromatic or polychromatic mode of operation. When- the polychromatic mode is used, the spectrophotometer shall operate with the specimen diffusely illuminated with the full emission of a continuous source that simulates either CIE Source A or CIE Source D65 in the visible spectrum. The specular component of reflection shall be included in the measurement. Specimens shall be measured as a single layer of fabric backed by six layers of the same fabric. Readings will be taken on a minimum of two different areas and the data averaged. The specimen shall be viewed at an angle no greater than 10 degrees from normal. Photometric accuracy of the spectrophotometer shall be within 1 percent and the wavelength accuracy shall be within 2 nm. The standard aperture size used in the color measurement device shall be 1.0 to 1.25 inches in diameter. Failure of the spectral reflectance requirements will have occured when spectral reflectance limits are exceeded at fo~r or more specified wavelengths.
