This standard provides a common method for determining the density of liquid adhesives and their components. Its core involves using a specialized metal weighing cup with a volume of 37.00 milliliters. During the measurement, the weight of the empty cup and the weight of the cup filled with the adhesive are determined under strict constant temperature conditions (typically 23±0.5°C). The density value is then obtained by calculating the ratio of mass to volume. This method is particularly suitable for adhesives with high viscosity or those containing volatile components, offering greater operational simplicity compared to the pycnometer method. The key testing instrument required for this procedure is this specialized weighing cup, which must be used in conjunction with a constant-temperature water bath capable of achieving the specified temperature control accuracy and an analytical balance with a precision of at least 0.001 grams.
