[ Policies and Regulations of Chemical Machinery Equipment Network ] Centrifuges are mainly used in the biological, medical, chemical, agricultural food and pharmaceutical industries to analyze the characteristics of samples for the purpose of separation and purification.
As the general basic equipment of the laboratory, large-scale procurement and long-term operation are its typical characteristics.
With the development of key core components and related technologies, some of the performance indicators of domestic centrifuges have caught up with or even surpassed similar imported centrifuges, but there are still problems such as low user acceptance, insufficient experience, and insufficient technical level.

With the development of key core components and related technologies, some of the performance indicators of domestic centrifuges have caught up with or even surpassed similar imported centrifuges, but there are still problems such as low user acceptance, insufficient experience, and insufficient technical level.
Gap in the evaluation system and specifications, insufficient technical personnel, and irregular procurement acceptance are the underlying reasons for the above-mentioned problems.
At present, user laboratory centrifuges include medical low-speed centrifuges, desktop high-speed centrifuges , refrigerated centrifuges, low-speed centrifuges, desktop high-speed large-capacity centrifuges, etc.
The centrifuges are diverse in types and mature in technology, and are widely used in user laboratories.
The feasibility of standard setting.

In view of the importance of centrifuge energy efficiency testing in laboratory work, in order to promote the vigorous development of the industry’s R&D technology level, in accordance with the "National Laboratory Instruments and Equipment Standardization Technical Committee Standards Preparation and Revision Management Measures", the Standards Committee will "High Energy Consumption Experiments" "Energy efficiency testing method for laboratory equipment, centrifuge" was declared as a project of the machinery industry standard plan.
At present, the "Energy Efficiency Test Method for High Energy Consumption Laboratory Equipment, Centrifuge" has been drafted for solicitation of opinions, and opinions are being solicited from experts.
At present, the "Energy Efficiency Test Method for High Energy Consumption Laboratory Equipment, Centrifuge" has been drafted for solicitation of opinions, and opinions are being solicited from experts.
This standard was drafted in accordance with GB/T 1.
1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents", and stipulates the terms and definitions, test conditions, test methods, etc.
of centrifuge energy efficiency testing.
This document It is suitable for the energy efficiency test of laboratory centrifuges with the rated maximum speed not greater than 30000 r/min.

of centrifuge energy efficiency testing.
This document It is suitable for the energy efficiency test of laboratory centrifuges with the rated maximum speed not greater than 30000 r/min.
The standard stipulates that the conditions that the environmental conditions of the centrifuge energy consumption test should meet include: ambient temperature: 23 ℃±2 ℃; relative humidity: ≤80%; air pressure: (80～106) kPa; no forced convection air.
After monitoring the test environment conditions and the power supply meets the test requirements, connect the electric energy metering device to the centrifuge power input terminal, measure the centrifuge rotor radius and the maximum speed of the rotor assembly and the sample mass corresponding to the maximum load, and install the rotor assembly and sample , Close the centrifugal chamber, and set the centrifuge to the startup mode with the highest speed and the fastest speed increase corresponding to the maximum load.
