(0) defects are found and rejected when one (1) or more defects are found. First article test

samples shall not be shipped.

4.3.1.1 Sampling for tests. Samples for tests shall be selected in accordance with

ASTM D4057.

4.4 Test. Samples selected in accordance with 4.3.1.1 shall be subjected to the

conformance tests specified in table II.

4.5 Control tests. When specified (see 6.2), the compound shall be subjected to the

control tests specified in table II. The frequency of control testing shall be determined by the

Government (see 6.2).

4.6 Methods of inspection.

4.6.1 Materials. Conformance to 3.2 thru 3.2.1.2 shall be determined by inspection of

contractor records providing proof or certification that materials conform to requirements.

Applicable records shall include specifications, design data, receiving inspection records,

processing and quality control standards, vendor catalogs and certifications, industry standards,

test reports, and rating data.

4.6.2 Inspection conditions. Unless otherwise specified (see 6.2), all inspections shall be

conducted under the following conditions:

a. Air temperature: 23 � 10�C (73 � 18�F)

b. Barometric pressure: 96 + 7, -10 kilopascals (kPa) (28.5 + 2, -3 inches

mercury (Hg)).

c. Relative humidity: 50 � 30%.

4.6.3 Defects. Conformance to 3.3.6 through 3.3.6.2, 3.5, and 5.1 shall be determined

by examination for the defects listed in table I. Examination shall be visual, tactile, or by

measurement with standard inspection equipment.

4.6.4 Halogenated hydrocarbons. To determine conformance to 3.2.1.2, a small loop of

18 to 20 gage copper wire shall be heated in the flame of a Bunsen burner until there is no color

to the flame. The loop shall be cooled and dipped into a sample of the compound being tested.

The loop shall be cooled and dipped into a sample of the compound being tested. The loop shall

then be placed in the outer portion of the flame and after the luminous flame had disappeared,

there shall be no green coloration in the flame. A green coloration in the flame indicates the

presence of a halogenated compound.
