3 Terms and definitions
For the purpose of this document, the following terms and definitions apply.
3.1
centrifuge tube (bottle); MEASURE with a point thermometer with the accuracy of 1 °C.
After operating for the operating time as specified in 5.4.3, the difference between the
measured sample solution temperature and the ambient temperature shall comply with
the provisions of 5.6.
6.7 Relative timing deviation
USE a stopwatch with the division of 1 s to measure the relative deviation between the
measured time and the set value at a set value of 5 min and 60 min or the maximum
time, which shall comply with the provisions of 5.7.
6.8 Acceleration and deceleration time
6.8.1 INSTALL the fully loaded rotor to be tested capable of rising to the maximum
speed of the centrifuge; MEASURE with a stopwatch with the division of 1 s;
6.8.2 TURN ON the centrifuge; MEASURE the time required for the rotor to rise from
standstill to the maximum speed, which shall comply with the provisions of 5.8;
6.8.3 When the rotor of the centrifuge is at the maximum speed, press the stop key,
and then measure the time required for the rotor to drop from the maximum speed to
standstill, which shall comply with the provisions of 5.8.
6.9 Refrigeration effect of refrigerated centrifuge
6.9.1 Refrigeration time
6.9.1.1 INSTALL the centrifuge with the maximum rotor corresponding to the maximum
speed; SET the maximum speed;
6.9.1.2 TURN ON the centrifuge and the refrigeration system, while timing with a
stopwatch with the accuracy of 1 s, to measure the time taken for the temperature of
the centrifugal chamber or the sample to fall to 4 °C, which shall comply with the
provisions of 5.9.2.
6.9.2 Temperature fluctuation deviation
6.9.2.1 ADJUST the centrifuge installed with the maximum rotor corresponding to the
maximum speed TO the maximum speed;
6.9.2.2 SET the temperature of the centrifuge chamber or the sample TO 5 °C, 10 °C,
15 °C respectively. Under each setting condition, when the temperature display or the
indicator reading reaches the set value, start reading after it is stable. READ the display
temperature every 5 min; READ five times per gear; CALCULATE the average value
of 5 temperatures of each gear; MINUS the set value. It shall meet the requirements
of 5.9.3.
6.10 Safety requirements
f) the pictorial marking for handling of goods such as “This Way Up”, “Fragile,
Handle with Care” and “Keep Dry” as specified in GB/T 191;
g) the storage and transportation conditions.
7.4 Instructions for use
The instructions for use shall meet the relevant requirements of national standards or
industry standards. Generally, it shall include the following.
a) the name, model, specification of the product;
b) the name, registered address, production address, contact information and after-
sales service organization of the production enterprise;
