Additionally, as of the date of the recall, 14 heaters had been returned to Lakewood with ruptured welds.The recalled heaters are portable electric radiator style heaters, with six fins or heating coils, one fin having the control panel attached to it. Lakewood electric heater manual. On January 26th, 2005 Lakewood Engineering and Manufacturing Company of Chicago, IL announced a recall of approximately seventy thousand (70,000) of its Model 5101 Electric Heater due to rupturing welds which expel oil, hurting consumers that may be nearby.Lakewood states that is aware of 28 incidents where the welds ruptured, and in one case a consumer was burned. The units are grayish in color and have the brand name 'Lakewood' below the indentation on the control panel.
The softening point is the temperature at which a material softens beyond some arbitrary softness.[1] It can be determined, for example, by the Vicat method (ASTM-D1525 or ISO 306), Heat Deflection Test (ASTM-D648) or a ring and ball method (ISO 4625 or ASTM E28-67/E28-99 or ASTM D36 or ASTM D6493 - 11). A ring and ball apparatus can also be used for the determination of softening point of bituminous materials.[2]
Dragon ball raging blast 2 iso ps3. The Vicat Softening Point is used to predict the temperature at which a plastic material will soften when used in an elevated temperature application. ARDL’s capabilities for vicat softening point testing include testing under flexural load and temperature for a variety of materials. Aug 19, 2013 The softening point is a test (usually called the ring-and-ball test) to determine the temperatures at which an asphalt binder achieves a specified degree of viscosity. In the test, a steel ball is placed on a disc of binder that is slowly heated until it.
