Description / Abstract:


This specification covers both woven and nonwoven absorbent materials supplied as either dry cloths or as presaturated cloths for solvent cleaning process applications.


These cloths have been used typically in cleaning smooth or textured, metallic and nonmetallic surfaces preparatory to processing operations which are sensitive to residual surface contamination, but usage is not limited to such applications. Cloths qualified to this specification are not intended for use on transparencies.


Cloths covered by this specification are classified as follows:

Class 1 Virgin cloth, composed of 100% cotton fibers, with or without added binders.

Class 2 Virgin cloth, composed of 100% synthetic or blended synthetic, cotton, or cellulose materials, with or without added binders, which remain stable up to 400 °F (204 °C).

Class 3 Empty classification (formerly presaturated cloths - see Form 2).

Class 4 100% polyester knit without binders.

Grade A For use in cleaning operations where exceptionally low residual surface contamination levels are required.

Grade B For use in cleaning operations where low residual surface contamination levels are required.

Form 1 Dry cloths (in individual wipes or rolls).

Form 2 Cloths contained in a presaturated wiping system, except that binders, surfactants, or other chemical treatments shall not be included (See 8.6). Solvents used in the presaturation process shall be designated and approved as acceptable by the purchaser.

Note: Purchaser should ensure that solvent and cloth used in presaturated wiping system are compatible and adequate for desired cleaning application.

Grade A cloths may be substituted for Grade B at any time for processing operations.

If no classification of cloth is specified, a Grade A, Form 1 cloth of either Class 1 or Class 2 shall be the default.
