ET3-039C: Practical Assessment Assessment overview - continued 4. Task - Using current limits and fits standards. Using BS 4500 Data Sheet A, Selected Fits determine: The limits of size for each of the hole and shaft combinations given below The minimum clearance or interference in each case The amount of tolerance for the hole and shaft in each case. 1.45 H7 g6 2.100 H7 k6 3.65 H7 p By means of a clear diagram show how the deviation and tolerance on a hole and shaft can produce: A clearance fit An interference fit. Producing a report (for Practical Assessment ET3-039C) You should produce a report that gives details of the following: The effect of carbon content on the properties being tested. Which specimen was the stiffest? Which specimen was the most ductile? Which specimen was the most elastic? Which specimen was the strongest? The effect that % carbon content on the properties has on the property being determined. bne laste nody Produce your report either by hand or by using a computer. If you use a computer you must ensure th it is all your own work. Note: Ask your tutor to help you if you are unsure of any points or terms used. Working safely in engineering: You must work in a safe manner whilst carrying out the practical activity within this assessment. You must use the correct manual handling procedures when moving objects within the workshop. Note: Ask your tutor to help you if you are unsure of any points or terms used
