How to correct the processing data of high and low temperature alternating test chamber
First, the test conditions of high and low temperature alternating test chamber:
1. The test should be carried out under no-load conditions;
2. When performing the cooling rate test, the ambient temperature should not be higher than 25 °C, and the cold power temperature should not be higher than 30 °C;
Second, the data processing and test results correction of high and low temperature alternating test chamber
1. Correct the measured temperature data according to the correction value of the test instrument;
2. Eliminate suspicious data;
3. Calculate the average temperature of 30 measured points per point for the data measured during the constant temperature phase;
4. Calculate the temperature gradient: the maximum value of the temperature average minus the minimum value of the temperature average;
5. Calculate temperature fluctuation and temperature deviation
6. The difference between the set value of the control instrument of the high and low temperature alternating test chamber and the central test value shall meet the tolerance requirement.
3. Calculation and evaluation of test results of high and low temperature alternating test chambers.
1. Correct the temperature value of the test according to the correction value of the test instrument;
2. Calculate the arithmetic mean of the temperature of each test point separately;
3. Calculate the percentage difference between the wall of the working chamber and the thermodynamic temperature of the working chamber.
A bookcase, or bookshelf, is a piece of furniture with horizontal shelves, often in a cabinet, used to store books or other printed materials. Bookcases are used in private homes, public and university libraries, offices and bookstores. Bookcases range from small, low models the height of a table to high models reaching up to ceiling height. Shelves may be fixed or adjustable to different positions in the case. In rooms entirely devoted to the storage of books, such as libraries, they may be permanently fixed to the walls and/or floor.
A bookcase may be fitted with glass doors that can be closed to protect the books from dust or moisture. Bookcase doors are almost always glazed with glass, so as to allow the spines of the books to be read. Especially valuable rare books may be kept in locked cases with wooden or glazed doors. A small bookshelf may also stand on some other piece of furniture such as a desk or chest. Larger books are more likely to be kept in horizontal piles and very large books flat on wide shelves or on coffee tables.
