Test Description Sample Clauses

Test Description. During the rotating bending test, the lateral forces acting on wheel in driving around a curve are simulated. Four wheel samples shall be tested, two at 50 per cent and two at 75 per cent of the maximum side force. The wheel rim is fixed rigidly to the test bench, and a bending moment M is applied to the hub mounting area (i.e. through a loading arm with a flange having the same pitch circle diameter as the vehicle for which the wheel is intended). Light alloy wheels are fixed using the internal rim flange by two semicircular flanges. Should other fixing devices be used, it is necessary prove their equivalence. Screws or fixing nuts are tightened to the torque stated by the vehicle manufacturer and retightened after 10,000 cycles approximately.

Test Description. In the rolling test the stress on the wheel when driving straight ahead is simulated by testing a wheel rolling against a drum which has a minimum outside diameter of 1.7 m, in the case of an external rolling test, or a minimum internal diameter equal to the dynamic radius of the tyre divided by 0.4 in the case of an internal rolling test. Two wheels shall be tested.

Test Description. Wheel strength with regard to the fractures on edges and other critical points when the wheel strikes an obstacle shall be checked. In order to show the sufficient resistance to fractures it is necessary carry out an impact test as per Annex 8 - Appendix 1.

Test Description. The direct rotary drilling method used a mud slurry as a drilling fluid during the construction operation. Site conditions necessitated use of this method. However, the mud cake has a deleterious effect on the production capacity of the well due to its very low hydraulic conductivity. Development was necessary to remove the mud cake to the extent practical. In this study, air development was used to surge compressed air into the casing of each well for approximately fifteen minutes. The key question, of course, was how much development was necessary to remove the mud without affecting the hydraulic properties of the aquifer materials outside the well? This was the main question studied in the field tests reported below. The series of testing performed on xxxxx A, B, and C were identical with a few exceptions and consisted of four sets of tests (Table VI-1). The first set consisted of an ambient flow test and a pump-induced flow test which occurred before any well development. The second, third, and fourth sets were identical in procedure; air development, followed by an ambient flow test, followed by a pump-induced flow test. Some pump-induced flow tests were repeated following an overnight rest period (without a repeat of the air development) Table VI-1. Pump-Induced Flow and Ambient Flow Tests Performed on Xxxxx A, B, and C Ambient Flow Tests Well A Well B Well C Pre-development — X X 1st Development — X X 2nd Development X X X 3rd Development Pump-Induced Flow Tests X X X Pre-development X X — 1st Development X X X 2nd Development X X X 3rd Development X X X Repeat Tests (Overnight) Ambient Flow Test 1st Development — X — Pump-Induced Flow Tests 2nd Development X — — to determine if the results were repeatable. The ambient and pump-induced flow tests were conducted in the same manner as far as flowmeter position was concerned. The electromagnetic flowmeter was lowered to the bottom of the borehole where the first measurement (zero reference) was taken. Subsequent flow measurements were recorded as the flowmeter was raised at 1.52-m increments until reaching the top of the screen. The pump-induced flow was maintained at a constant rate and averaged about 34 L/min for all tests.
