In general, the industrial grade is used in the process of production, the specific content standard is based on the product properties of the decision.
Generally speaking, military grade is the highest, industrial grade is second, then commercial grade, and finally civilian grade.
Take the electronic power supply as an example:
Military-grade power supply, the requirements are very strict, such as waterproof, fireproof, anti-fall, anti-electromagnetic and so on have the requirements;
Industrial-grade power supply, there is no military power supply side of the strict. But on the waterproof, fire has certain requirements;
Commercial power supply, to be lower than the industrial power supply of waterproof and fire requirements;
Civilian power supply, that is, we generally use the power supply, is not a very strict requirements, but there are certain requirements in the requirements,
These requirements are divided into levels, the level of the chemical division is based on the quality of the power supply, the requirements and the use of the classification!
The working reference reagent (national standard without abbreviation mark, indicated in Chinese, green label): as a reference material, calibration standard solution.
Superior purity (GR, green label): the main component content is very high, high purity, suitable for accurate analysis and research work, some can be used as a reference material.
Analytically pure (AR, red label): the main component content is very high, high purity, low interference impurities, suitable for industrial analysis and chemical experiments. This is the most used grade in general laboratory.
Chemically pure (CP, blue label): high content of the main components, high purity, the presence of interference impurities, suitable for chemical experiments and synthetic preparation.
Laboratory reagent (LR, yellow label): high content of the main components, poor purity, impurity content is not selected, only for general chemical experiments and synthetic preparations.
Question 2: What do you mean by industrial grade? Depending on what you say in that area, such as food:
The so-called industrial grade, agricultural grade, food grade, reagent pure, analytical pure and so on just according to the use of different divisions
For example, the industrial grade is in the process of production used in the process of production, the specific content of the standard is based on the properties of the product to decide.
Agricultural grade and food grade are used in agriculture and food industry, and others are the same
Reagent pure, analytical pure generally used in the laboratory
In electronic products:
There are commercial-grade, industrial-grade and military-grade products,
For example, the industrial-grade standard of the electronics is the main reference for the standard for China's national standard GB 4208-93 "enclosure protection level (IP Code)", IEC standards (IEC 60329-2001) "Degrees of protection provided by enclosures (IP Code)" or Nema 250-2003 "Enclosures for Electrical Equipment (1000 Volts Maximum).
Mainly different standards (with authoritative definitions) plus national standards, such as XX products in line with the GJB (National Military Standard) blah blah blah, MIL (U.S. Military Standard) blah blah blah.
Generally speaking, military grade is the highest, industrial grade is second, then commercial grade, and finally civilian grade.
Take the electronic power supply as an example:
Military-grade power supply, the requirements are very strict, such as waterproof, fire, fall, anti-magnetic and so on have to attack;
Industrial-grade power supply, there is no military power supply side of the strict. But on the waterproof, fire has certain requirements;
Commercial power supply, to be lower than the industrial power supply of waterproof and fire requirements;
Civilian power supply, that is, generally we use the power supply, is not very strict requirements, but there is a certain in the requirements,
These requirements are divided into levels, the level of the chemical division is based on the quality of the power supply, the requirements and the use of the classification!
Question 3: What is the industrial grade ah Industrial grade is the common classification of electronic equipment, general electronic equipment is divided into commercial industrial military and other classifications. Industrial grade to meet the general industrial site of the environmental atmosphere. If used in harsh environments will not apply. For commercial environments and high cost.
Question 4: What is the meaning of industrial grade industrial grade, agricultural grade, food grade, reagent pure, analytical pure, etc. is divided according to different uses.
Industrial grade is used in the process of production, the specific content standards are based on product properties.
Generally speaking, military grade is the highest, industrial grade is second, then commercial grade, and finally civilian grade.
Take the electronic power supply as an example:
Military-grade power supply, the requirements are very strict, such as waterproof, fireproof, anti-fall, anti-electromagnetic and so on have the requirements;
Industrial-grade power supply, there is no military power supply side of the strict. But on the waterproof, fire has certain requirements;
Commercial power supply, to be lower than the industrial power supply of waterproof and fire requirements;
Civilian power supply, that is, we generally use the power supply, is not a very strict requirements, but there are certain requirements in the requirements,
These requirements are divided into levels, the level of the chemical division is based on the quality of the power supply, the requirements and the use of the classification!

Laboratory reagent (LR, yellow label): high content of the main components, poor purity, impurity content is not selected, only for general chemical experiments and synthetic preparations.
Question 5: What is the meaning of industrial grade as stated in hardware tools Industrial grade tools were initially proposed by Wu Xianfa, the veteran president of Pioneering Tools International Group.
An ordinary family a wrench may be used for a lifetime, but if you put it in the car repair store? Hundreds of times a day repeated use, you can not imagine, a lifetime of not bad wrench half a day can not work, this time there is a requirement to be able to withstand repeated testing of the tool, industrial-grade tools came into being, industrial-grade tools used in the materials, manufacturing processes and ordinary tools are very different, not only this, each industrial-grade tools have to be repeatedly tested, each industrial-grade tools have to be carefully checked before entering the market. scrutinized before entering the market.
Question six: what is called industrial-grade professional air conditioning Industrial-grade air conditioning to control the temperature and humidity of the environment precision is not as high as precision air conditioning, industrial-grade sense of the air-conditioned environment.
Industrial air conditioners have Daikin, precision air conditioners have Emerson, stulz, APC, RC, etc..
Question 7: What is the meaning of touch screen industrial grade? Three defense mainly refers to what? Industrial site protection level generally refers to waterproof and dustproof, the third defense does not seem to have specifically referred to,
But some customers have raised, it seems to be anti-oil
Question 8: What is the industrial-grade white sugar Industrial sugar refers to raw sugar.
The standard implemented for industrial sugar is GB 15108-2006 Raw Sugar.
Raw sugar contains a certain amount of impurities, the color is darker than white sugar, contains relatively more water and molasses, microbial content is also higher than white sugar. Raw sugar can only be used for industrial production (mainly used to produce white granulated sugar or sugar), can not be consumed directly, can not be added directly to the food as raw materials.
Mianbai sugar is extracted from sugar beets, granulated sugar is extracted from sugar cane, the general origin of mianbai sugar is the north, and granulated sugar is the south.
The sweetness of white sugar is higher than granulated sugar, the use of granulated sugar is not very different, I generally do not like to use white sugar, because it is very difficult to save, but also to prevent moisture and also to prevent the dry knot ~, to take the time to use the sticky and sticky to get not refreshing industrial white sugar and edible white sugar is no difference, are white sugar.
Sugar is mainly white sugar and white sugar. White color, particles such as sand, called white sugar; white color, fine and soft, easy to melt in the mouth, called cotton sugar. White sugar is the crystallization of sucrose, purity is generally more than 99.8%, from a chemical point of view, this is a very pure substance. White sugar has a pure sucrose sweetness, in addition to direct consumption, but also the main varieties of industrial sugar. Mianbai sugar is fine sucrose crystals wrapped in a layer of converted sugar syrup, the purity of which is comparable to that of white granulated sugar. Converted sugar plays a role here in softening, flavoring and sweetening. This is because the converted sugar has a honey-like flavor (honey is the main component of the converted sugar) and its sweetness is greater than sucrose (to the sweetness of sucrose for 1, the sweetness of the converted sugar is 1.2), converted sugar's strong ability to absorb water to keep the sugar grains of the brocade soft, so the texture of the sugar is better than white sugar.
Question 9: What is the difference between household-grade, commercial-grade and industrial-grade products? National standards for some products are divided into military, civilian (including industrial), of course, military standards are higher.
What companies call home-grade, commercial-grade, industrial-grade, and enterprise-grade are all self-defined quality level divisions of companies, and there is no uniform regulation. Generally speaking, commercial grade, industrial grade, enterprise grade quality standards are higher, this is because in the case of commercial, industrial, enterprise use, the use of poorer conditions, longer use, so the quality requirements are higher.
For example, a juicer in a home situation, not used several times a day, each time the time is not long, but in the commercial situation of the beverage store, often several hours of frequent use, obviously, commercial-grade juicers should have higher quality standards.
