Determine the specific gravity of the paint using mass per litre cup. The use of volume nonvolatile matter values in such instances should be carefully considered as the increased volume is largely due to air trapped in these voids. Note the weight of the stainless-steel disc. This value is useful for comparing the coverage square feet of surface covered at a specified dry film thickness per unit volume obtainable with different coating products.
Allow the excess coating material to drain off. I married on 30 th June having one baby Above the critical pigment volume concentration, the apparent volume of the dry film is significantly greater than theoretical due to the increase in unfilled voids between pigment particles.
Fixed solids – solids that remain after firing a sample in a Deg C muffle furnace. Link to Active This link will always route to the current Active version of the standard.
[email protected]: Technical – Volume solids or solid content
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. These test astmm cover procedures for assessing the adhesion of coating films to metallic substrates by applying and removing pressure-s Blot the coating material off the bottom edge of the disc so that beads or drops do not dry on the bottom edge of the disc.
Let it be W3, grams. Determined by evaporating a known volume of the filtrate sample in a Deg C oven. Determined directly by evaporating a known volume of an unfiltered water sample in a Deg C oven. Let it be W4 grams.
ASTM D – 03 Standard Test Method for Volume Nonvolatile Matter in Clear or Pigmented Coatings
Let see how to test the TSS:. Weigh the coated disc in air. This can be tested using IS – part Total dissolved solids – includes all solids present in a water sample filtered through a 1. Historical Version s – view previous versions of standard. Weigh the disc in air. Determined by filtering a known volume of sample and placing the filter and filter container in a Deg C oven for 24 hours to evaporate the water.

ASTM D2697 – 03(2014)
Suspend the disc in water and weigh again. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Take Stainless Steel Disc 60 mm diameter and 0. Total solids – includes all solids present in a water sample. Total suspended solids – includes all solids present in a sample that remain on a 1. The values given in parentheses are for information only. An interlaboratory study to establish the precision of this test method included a water-reducible exterior latex paint and three automotive coatings that included a solvent-reducible primer surfacer, water reducible primer surfacer, water reducible enamel topcoat, and acrylic dispersion lacquer topcoat.
Let it be W1, grams. Suspend the coated disc in water and weigh again. Dip the disc in the paint sample for 10 minutes and take out the disc. Let see how may types of solids are there in liquid products or materials: Let it be P.
One reason is that the volume occupied by a solution of resin in solvent may be the same, greater, or less than the total volume of the separate ingredients: Can be performed on total, dissolved, or suspended samples to determine – total volatile solids, volatile dissolved solids, or d22697 suspended solids. Earlier collaborative studies included a gloss enamel, a flat wall paint, a gloss house enamel, an industrial baking enamel, asmt interior latex paint, and an exterior latex paint.
Can be performed on total, dissolved, or suspended samples to determine – total fixed solids, fixed dissolved solids, or fixed suspended solids.
