- Description
- *** 20 April 2010 *** There have been a few questions relating to certain parts of the purchase description that have been asked and the responses to those questions have been posted here for viewing. This amendment also extends the due date for proposals by 3 weeks to 17 May 2010. Question: Please provide specific dimensions of the scales that are being calibrated, i.e., length, width, height. Response: The sizes of the scales vary. Question: How will the scales be centered in the calibration frame? We are particularly interested in how the corner test will be performed. An example of a test article would be insightful. Response: I have no test articles available, but I can provide examples of Mfrs and P/Ns, if necessary. Question: What are the details of the top of the scale? Flat surface or mechanical connection? Response: The scale will be calibrated as received (assembled) but the press may be needed to adjust the scale, which may mean that the top may have to be removed. In all cases, there will be a plate between the press load cell and the scale. Question: 4.4.5.2.1 of purchase description. The transit case called out, ECS 00017529 has dimensions of L-19.01 x W 12.01 x H10 can multiple load cells be place in one case or does each load have to have its own case. Some of the smaller load cells could be combined. Response: Per 4.1.5.2.1, each load cell is to have its own case. Question: 4.1.5.1 All components shall be corrosion proof, does this mean that the press has to be stainless steel or can components be plated or treated for corrosion. Do the electrical control cabinets have to be stainless steel Nema 4. Response: No, all components of the press (load frame), load cell and adapters shall be corrosion-proof. Electronic components are excluded. No other requirements have been stated. Question: 4.1.5.3 The load cell calls for 340uin or.00034 thousands of the inch is this correct. Response: Yes; The PD says no less than 340 uin, but not no greater than. This, of course, means it can be larger than 340 uin. Question: What type of surface material and size should the load cell have mounted on the surface which comes in contact with the scales. Response: Distribution plates will be used between the load cell and scale; load cell surface shall be such that it will not cause deformation/damage to both a 1.75 in Al plate or a 0.5 in hardened steel plate. It also shall not cause damage to the load cell itself. Question: 4.1.5.4 The flatness for the 48 x 48 inch working surface is call out a 200 uin or.0002 thousands of the inch. Please clarify if this means.0002 per inch for a total of.0096 over the total surface. Response: Again, the PD says no less than 200 uin, not no greater than. This means that it can be larger than 200 uin. No - the spec is not 200 uin per inch, but it could be if the mfr states it in the overall uncertainty analysis. Question: 4.1.4.3 What range on the 48 x 48 inch working surface should the load call be able to reach. Should these limits be reach under power or manually. If powered the load cell must then be driven on 2 axis over the table and a third axis the apply the test load. Response: Para 4.1.4.5 states that the working height shall be 4 to 10 inches. Para 4.4.2.3 states that there will be a manual override. Para 3.1 says the press shall be able to be run in both manual and automatic mode.
