Purpose:

This standard gives the general physical, electrical and chemical methods for testing fiber optics cables for conformance with the requirements. It was prepared in order to eliminate unnecessary or undesirable variation in testing procedures. This standard does not include special test methods applicable to certain fiber optics cables which are described in the appropriate specifications, nor does it include all the test methods for fiber optics cable used in industry. In instance of conflict between the provisions of those test methods and those of the individual test procedures or specifications for particular material, the latter shall take precedence.

Application of test methods:

Test methods contained in this standard apply to all items of equipment. WHEN IT IS KNOWN THAT THE EQUIPMENT WILL ENCOUNTER CONDITIONS MORE SEVERE OR LESS SEVERE THAN THE ENVIRONMENTAL LEVELS STATED HEREIN, THE TEST MAY BE MODIFIED BY THE EQUIPMENT SPECIFICATION.

Numbering system:

New methods: A method number will be assigned so that the new method is located close to the methods of similar or related tests.

Revision of existing methods: Revision of test methods are indicated by a letter following the method number. For example, 3111, if modified or changed, would be 3111A, the second revision, 3111B, etc.

Method of reference:

Test methods contained herein shall be referenced by specifying:

a. This standard number

b. Method number. The letter following the method number shall not be used when referencing test methods. For example, use 1010, not 1010A.

c. Procedure number

d. Details required in the results paragraph of the applicable method.

e. Other data as called for in the individual test method.
