foam height test procedure

The one that @vitalys posted looks about the procedure we used at Alberto. range should be between 120 f and 35 f. Freezing and thawing will not harm foam. You measure the height or volume of foam generated and its decay over time. Due to drainage, foam at the top dries until it reaches a critical film thickness for collapse, giving the maximum foam height (H0). The basis of this test is a simple blood sample, which is then looked at in a lab. em88 Member. The Foam Test measures the foaming tendency of a lubricant. Does anyone have the written procedure for testing shampoo foam height using a dilute solution in a blender? Density is expressed by the weight per cubic foot. This test method is used in … Sorry to bring this post up again, but does anyone still have the PDF? The action is intermittent, time being alloted strictly for foam decay, as well as for foam generation. Per NFPA 11: Do not mixing unlike foam brands. A new, simple foam test, in which a well-controlled volume of gas is introduced into a definite volume of solution, is presented along with the method of analysis. Say the density of a mattress is four pounds per cubic foot. This controller offers flexibility with regard to control, data obtainment, analysis, and reporting. Analyzing Foaming Tendency: Foam Test. If the premix solution is mixed too rich—too much foam concentrate and not enough water— there is a risk running out of foam before the fire is fully extinguished. The test manifold on the foam/water sprinkler system allows testing to be performed without discharging the foam/water solution from the sprinkler heads them-selves. According to this test, also referred to as ASTM D892, the tendency of oils to foam can be a serious problem in systems such as high-speed gearing, high-volume pumping, and splash lubrication. Never mix class A foam with Class B foam. Foam testing should be close to the desired application. October 2017. This arrangement allows periodic The test manifold verifies the proper mixture of water and foam concentrate developed by the propor-tioning equipment. Inadequate lubrication, cavitation, and overflow loss of lubricant can lead to mechanical failure. During an IFD test, the MTESTQuattro software charts live load and foam height over time. Learn to formulate cosmetics. A report from the controller consists of the force of deflection, support factor, specimen identifier, load, and time. Storage temp. Weight ÷ Width x Height x Length = Density. foam concentrate in boiler rooms, out-door sheds or attics. To calculate the density of a piece of foam, you divide the weight of the foam by its width x height x length. This method measures the height of foam developed by pouring. could occur in a test. Using this method, a foaminess index (Σ) of the foam can be determined; this index is the ratio of foam volume generated by a given gas flow rate: Σ = H0 / Ug (1) II.-Shaker bottles. 5.1 The tendency of oils to foam can be a serious problem in systems such as high-speed gearing, high-volume pumping, and splash lubrication. Comparative or duplicate tests can be prolonged indefinitely, or until a steadied state is reached. Aqueous solutions of sodium dodecyl sulfate (SDS), n-octyl-β-d-glucopyranoside, hexadecyltrimethylammonium bromide (CTAB), and n-hexanol, i.e., four systems forming metastable and transient foams, were studied.
