Volume Nonvolatile Matter in Clear or Pigmented Coatings – ASTM D2697
Total suspended solids – includes all solids present in a sample that remain on a 1. 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. Determine the specific gravity of the paint using mass per litre cup. 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. Dip the disc in the paint sample for 10 minutes and take out the disc.
Weigh the adtm in air.
Let it be W3, grams. Above the critical pigment s2697 concentration, the apparent volume of the dry film is significantly greater than theoretical due to the increase in unfilled voids between pigment particles.
Can be performed on total, dissolved, or suspended samples to determine – total volatile solids, volatile dissolved solids, or volatile suspended solids. Determined directly by evaporating a known volume of an unfiltered water sample in a Deg C oven. Technical – Volume solids or solid content. 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.
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.
Note the weight of the stainless-steel disc. Let it be W grams. Let see how to test the TSS:. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Earlier collaborative studies included a gloss enamel, a flat wall paint, a gloss house enamel, an industrial baking enamel, an interior latex paint, and c2697 exterior latex paint.
Suspend the disc in water and weigh again.
[email protected]: Technical – Volume solids or solid content
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. Total solids – includes all solids present in a water sample. Take Stainless Steel Disc 60 mm ashm and 0. Suspend the coated disc in water and weigh again.
This can be tested using IS – part Let it be W1, grams.
Link to Active This link will always route to the current Active version of the standard. Weigh the coated disc in air. Can be performed on total, dissolved, or suspended samples to determine – total fixed solids, fixed dissolved solids, or fixed suspended solids.
Fixed solids – solids that remain after firing a sample in a Deg C muffle furnace. Total dissolved solids – includes all solids present in a water sample filtered through a 1. The values given in parentheses are for information only. Let it be P. Let it be W4 grams. Allow the excess coating material to drain off.
These test methods cover procedures for assessing the adhesion of coating films to metallic substrates by applying and removing pressure-s Let see how may types of solids are there in liquid products or materials: Determined by evaporating a known volume of awtm filtrate sample in a Deg C oven.
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: I married on 30 th June having one baby Historical Version s – view previous versions of standard. 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.
