4.6 Methods of testing. All testing shall be done in a standard condition environment defined by the ASTM D1776, if not specifically defined by the individual test procedure.

4.6.1 Moisture vapor transmission rate. ASTM E96 with temperature and humidity conditions of 73.5 o F ( + 1) o F and 50( + 2) percent relative humidity. The linear air flow velocity in the wind tunnel shall be set to yield an upright, „open cup‟ evaporation rate at all test specimen positions of 15,000 (+ 1,000) grams per square meter after twenty-four (24) hrs, (the evaporation rate shall be determined by conducting an upright cup, Procedure B test without a test specimen for a period of exactly two (2) hours).

4.6.1.1 Procedure B. ASTM E 96. The back side of the basic material shall face the water.

The test specimen shall be conditioned, after set-up in the test cup with water level of 3/4

(+ 1/16) inch below the specimen surface, in the wind tunnel for a period of not less than four (4) hours and not more than sixteen (16) hours. Conditioning time of less than four (4) hours may be used provided that equilibrium conditions have been demonstrated to exist within the test sample/sample cup/wind tunnel. (In cases of dispute, the conditioning time shall be four (4) hours.). After conditioning, the cup shall be immediately weighed to start the test and again after exactly twenty-four (24) hours to complete the test. Five (5) specimens shall be tested.

4.6.2 Blocking. Blocking Resistance at Elevated Temperatures, except that the tests shall be performed at a temperature of 180 o F (+ 2) o F for thirty (30) minutes. Only one (1) specimen shall be tested. Evaluate the resistance of the specimen to blocking by the scale given below:

1 -- No Blocking. Cloth surfaces are free and separate without any evidence of cohesion or adhesion.

2 -- Trace Blocking. Cloth surfaces show slight cohesion or adhesion.

3. -- Slight Blocking. Cloth surfaces must be lightly peeled to separate.

4 -- Blocking. Cloth surfaces separate with difficulty or coating is removed during separation.

4.6.3 Water permeability. ASTM D 751, Hydrostatic Resistance, Procedure B, Procedure 1 with a rising hydrostatic head at 10 millimeters per second applied to the face side of the test specimen. Five (5) specimens shall be tested. Leakage is defined as the appearance of one (1) or more droplets of water within the 4-1/2 inch diameter test area.

(or areas) taken at various locations across the sample unit shall be tested. Evidence of wetting on one (1) or more specimens shall be considered a test failure.

4.6.5.2 After 5 launderings. Test specimens shall be laundered for five (5) laundering cycles in accordance with 4.6.9.1.1 and then tested for resistance to organic liquids in accordance with

4.6.5.1.

4.6.7 Pattern execution. The pattern of the cloth shall be matched to the pattern, Drawing

No. 2-1-2519 for Class 1; for Class 2 (see 6.4).

4.6.8 Spectral reflectance. Spectral reflectance data shall be determined on the face side and shall be obtained from 600 to 860 nanometers (nm) at 20 nm intervals on a spectrophotometer, relative to the barium sulfate standard, the preferred white standard. Other white reference materials may be used provided they are calibrated to absolute white, e.g., magnesium oxide or vitolite tiles. The spectral band width shall be less than 26 nm at 860 nm. Reflectance measurements may be made by 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 source that simulates either CIE source A or CIE source D65. The specimen shall be measured as a single layer, backed with six layers of the same fabric and shade. Measurements shall be taken on a minimum of two (2) different areas and the data averaged. The measured areas should be at least 6 inches away from the selvage.

The specimen shall be viewed at an angle no greater than 10 degrees from the normal, with the spectral component included. Photometric accuracy of the spectrophotometer shall be within 1 percent and wavelength accuracy within 2 nm. The standard aperture size used in the color measurement device shall be 0.3725 inches in diameter or larger.

4.6.12 Elongation. Cut a 14-inch specimen from a representative sample cord and make two marks on the cord so that a distance of 10-inches is between the gage marks. Suspend the cord from a clamp in such a manner as to allow a 2-pound weight to be hung on the lower end of the cord. Gradually lower the weight until the entire load is carried by the cord. After two (2) minutes, take a measurement between the two marks and calculate the increase in length as follows:

Elongation (%) = B-A x 100

4.6.14 Toxicity test. When required (see 6.2), an acute dermal irritation study and a skin sensitization study shall be conducted on laboratory animals. When the results of these studies indicate the shirt is not a sensitizer or irritant, a Repeat Insult Patch Test shall be performed in accordance with the Modified Draize Procedure (See 2.3). If the toxicity requirement (see 3.11) can be demonstrated with historical use data, toxicity testing may not be required (see 6.2).
