The standard HG/T 4435-2012 "Determination of density of dyeing and finishing aids for Spinning & weaving" specifies two methods for determining the density of dyeing and finishing aids for Spinning & weaving: The Density Meter method is suitable for liquid-like aids, and the given volume weighing method is suitable for powder, block or mass-like aids. The Density Meter method determines the density by measuring the depth of immersion of the Density Meter in a liquid under thermostatic conditions; the given volume weighing method calculates the density by weighing a given volume of aids. The standard details the instruments and equipment required for the experiment, including Density Meter, thermostatic bath and measuringflask. Ensure that the density of Spinning & weaving dyeing and finishing aids is accurately determined under specified conditions to ensure conformity and comparability of product mass.
