# ASTM D5095

Standard Test Method for Determination of the Nonvolatile Content in Silanes, Siloxanes and Silane-Siloxane Blends Used in Masonry Water Repellent Treatments

[Back to all techniques](/analytical-techniques/)

## Significance and Use

4.1 This test method is used to determine the nonvolatile content of silanes, siloxanes, and silane-siloxane blended materials used in masonry water-repellent treatments. It can be used for the purpose of calculating the volatile organic compound (VOC) content of these materials under specified test conditions.

## Scope

1.1 This test method describes a procedure for the determination of the nonvolatile content (\_N\_s) of silanes, siloxanes, and blended silane-siloxane materials used in masonry water repellent treatments and is applicable to both solvent- and water-borne materials.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
