Aim: Study the effect of the addition of Sodium Carbonate (Washing Soda) on the foaming capacity of different soap solutions. Test Method : Draves-Clarkson Test 23. 18. Fire foam testing includes: Appearance, visual • Fuel is floated on a water layer, 1 cm in thickness. b) To check the foam concentrate for the effect of freezing. Prepare a soap solution by dissolving about 1 g of your laboratory made soap in 60 mL (4 tablespoons) of warm water. With the automated test procedure of the SITA FoamTester the parameters of energy insertion such as stirring speed, stirring duration, stirring direction, acceleration and number of stirring intervals can be adjusted. Section C specifies a method for measuring the compression force necessary to produce a 50% deflection over the entire top surface of the foam test specimen. Comparative or duplicate tests can be prolonged indefinitely, or until a steadied state is reached. ASTM D3574 C | Foam | Compression Testing. Firefighting Foam School and the Foam Testing Service. Repeat the same procedure for test tubes 2, 3, 4 and 5 shaking each time with the same force and for the same time (one minute). c) To check the foam concentrate for the possible effects of elevated tempera-tures. For diesel fires, 5 cm3 of a 1:2 mixture of ethanol and toluene is also added, to facilitate rapid ignition. When you amass a bunch of tiny bubbles together, we call it foam or lather.It doesn't matter if you're talking about bar soap, shampoo, dish soap or laundry detergent -- the same thing happens when you mix any of them with air and water. Recently, a new automated mechanical foam tester, SITA Foam Tester R2000, has been introduced to the market ( SITA Messtechnik GmbH, 2008 ), and it offers easy and repeatable testing and monitoring of the foaming characteristics for foaming liquids. Background 1. Solubility-Organic Solvents (A) The procedure was as in Example 1, except that the foam inhibitor was sprayed onto the spray-dried detergent in amounts of 0.2 and 0.5%. 5 mL of distilled water is added to test tube A. General Test Procedures 4.1.1. The Foam Test measures the foaming tendency of a lubricant. Laboratory requirements to conduct the testing 2. The action is intermittent, time being alloted strictly for foam decay, as well as for foam generation. The added AEA leads to foam formation on top of the liquid surface, which initially behaves in an unstable manner. Fire foam storage containers operating under harsh environmental conditions, such as ships, terminals, offshore platforms, and airports, should be routinely monitored for fire foam contamination and deterioration. Conventional methods of generating foam are based on mechanical principals such as agitation (ASTM D3601-88 (Re-approved 1997)), beating (DIN 53902-1), Ross-Miles Method (DIN 53902-2), shower (DIN 51395-1) or insertion of air. The measurement of the foaming properties of soaps and detergents is shown to be possible by comparing the relative stability of a foam by measuring the effect of an arbitrary standard destructive mechanism acting upon a volume of foam during production under standard conditions and protected from adventitious destructive forces.2. Test Method : Ross-Miles Pour Foam Test 28. 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. A foam testing service is available at our laboratory which will provide a full analytical report on your samples. The Ross-Miles method is used for measuring the foamability of surfactant solutions and the stability of the foam produced, which is based on height measurement. Analyzing Foaming Tendency: Foam Test. Contains a step by step, easy to follow manual, together with worked examples. 3.2.3 foaming tendency, n—in foam testing, the amount of foam determined from measurements made immediately after the cessation of air flow. The soap for which the time taken for the disappearance of foam is highest has maximum foaming capacity and is the best quality soap among the soaps tested. 5 mL of stock soap solution is added to test tube B.
