- Description
- REQUEST FOR QUOTATION SB1341-07-RQ-0155 AMENDMENT #0002 The above referenced request for quotation is hereby amended to respond to technical questions, and extend the due date for quotes. (1) The following responses are provided to technical questions submitted: QUESTION: There are a number of traditional approaches used in rheology to provide environmental protection, which, in many cases, is sample specific. Do you have a specific method in mind or are you simply looking to provide a sealed enclosure to keep the sample isolated from the atmosphere while in the oven and at temperature? If so, do you also want to inject a specific environment into the sample chamber? Or, is this something you expect to use for a some specific samples over a specific temperature range? ANSWER: NIST?s requirement is to have a general-purpose environmental chamber such as conventional oven with broad range of operating temperature and then purge with inert gas. Such an arrangement must be compatible with any DMA tool for mechanical properties if we wish to buy it in future. QUESTION: Over the years, researchers have looked at various optical approaches to understand their material's behavior. What is the orientation of interest; from the bottom of the sample looking up or from the side edge of the sample looking in? With plate or couette geometry? What is the camera resolution? Do you want to this option over the same temperature range or just at room temperature? ANSWER: NIST?s requirement is to study the microstructure of the sample looking through the plate while it is being sheared. The orientation is not relevant as long as we can study the microstructure of the sample during shear. NIST uses parallel plate or cone and plate geometry. The Camera must allow us to take movies in the shear rate range 0.5 per second to 1000 per second of the microstructure ranging from 5 microns to 1-2 mm. NIST?s requirement is to work in temperature range between ?20 to 250 degrees Celsius. (2) The due date for quotations is hereby changed to read as follows: FROM: Friday, April 27, 2007, at 3:30 PM EST, TO: Wednesday, May 2, 2007, at 12:00 PM EST.
