What is Schlesinger test?
A qualitative test for urobilin in urine. The urobilinogen in the urine is first oxidized by iodine to urobilin, then a zinc‐urobilin complex is formed by addition of zinc acetate …
Which tool is used in inspection during the acceptance tests of new machines?
Test Mandrels
1.1.(b) Test Mandrels The most widely used inspection tool during manufacture and acceptance tests of new machine tools, and the repair of old ones, is the test mandrel, the quality of which (especially as far as straightness and roundness are concerned) is of paramount importance for accurate results.
Why alignment test of a machine tool is necessary?
Answer. In order to meet quality requirements and minimise the number of waste workpieces, the checking and alignment of machine tools is essential. The most important thing to check is the geometry of the machine; not even a precisely calibrated linear motion can compensate for a crooked movement or uneven surface.
What is alignment test in metrology?
It is done by fixing the dial indicator in the tool post. A mandrel is fitted in the spindle. The dial gauge feeler is pressed against the mandrel in vertical plane and the upper slide is moved longitudinally. This type of error is not tested in horizontal plane because there is swiveling arrangement for taper turning.
How is Urobilin derived from urobilinogen?
Urobilin is formed through the oxidation of its parent compound uroblinogen. Urobilin is actually generated through the degradation of heme, the red pigment in haemoglobin and red blood cells (RBCs). RBCs have a life span of about 120 days.
What is final acceptance test?
The Final Acceptance Test is an evaluation carried out during the commissioning phase by an independent third party to demonstrate completion of the plant, as well as correctness and high quality of work. The FAT involves a review of design, labelling of equipment and a visual inspection of the facility.
How do you perform a factory acceptance test?
Basics of a Factory Acceptance Test
- Connections, to ensure they meet specifications for type, size, and location.
- Control panel location and installation.
- Drain connections, type, size, and location.
- Overall dimensions.
- Workmanship.
- Welding and weld documentation verifications.
- Major equipment and materials of construction.
What is geometrical test?
We test a pair of symmetry peaks to see if their position on the face is geometrically valid. If these peaks are not horizontally aligned or have insufficient intra-ocular distance, they could not be eyes and are to be discarded.
Which of the factors are checked during alignment test?
The three factors that affect alignment are toe-in, camber and caster. The first two can easily be checked at home.
Why the laser is used in alignment testing?
Laser alignment allows precise measurements that reduce your energy consumption in the long term. Poorly aligned machines require more energy to achieve the same results as a well-aligned asset. Reduced energy consumption is not only good for your electricity bill but of course also for the environment.
Is urobilin a waste product?
2. (A) Chemical structure of bilirubin, stercobilin, and urobilin. These products are generated from hemoglobin metabolism, and are found in human waste products.
