100 points ~ The difference between Category I films, Category II films and Category III films
Category I films have no plot and go straight to the theme. Category II films have a small amount of plot and are mixed with the theme. Category III films The film has more plot than theme, giving you space to think about how to classify Class I, II, and III home appliances
Class I appliances are waterproof, ground leakage protection,
Class II appliances are Double insulation protection,
Category 3 is ultra-low voltage protection! Are junior colleges also divided into Category I, Category II and Category III schools?
That’s right. There are one, two and three undergraduate books. There are first and second majors.
You can find out the details in your local admissions directory. hehe. The difference between first-class, second-class and third-class universities in China
In China, enrollment is divided into first batch, second batch and third batch, which correspond to key, second and third batch universities respectively. How to distinguish between Category I, Category 2 and Category 3 prefabricated components?
Prefabricated components are divided into: Category 1: hollow panels and solid panels within 4m. Category 2: piles, roof panels, industrial floor slabs, depth beams, foundation beams, crane beams, stair slabs, stair sections, balcony slabs within 6m; Category 3: beams, slabs, columns, piles from 6m to 14m, and various roof trusses , trusses, brackets.

Wow, it’s very difficult to distinguish. Generally speaking, only experts will review it and it will be divided into several categories. So it’s hard to tell. If you want to see it, just look at the certificate. Do Category 2 and Category 3 accounts include foreign currencies?
Category 1 accounts include foreign currencies. From December 1, the same person can only open one Category I account in the same bank. If a Category I account has been opened, If you open a new account, you should open a Type II account or a Type III account. You can only open one Type III account at the same payment institution.
Only one type of account can be opened. Type I accounts refer to accounts opened through traditional bank counters and that meet all the strict requirements of the real-name system. To put it simply, it is the savings card or debit card you hold in your hand. Its functions include deposits, purchasing financial products, cash withdrawals, transfers, consumption and premium payments, etc.
Category II accounts cannot deposit or withdraw cash, nor can they transfer funds to unbound accounts. The single-day payment limit for this type of account is 10,000 yuan. This is the case with credit cards, for example.
Category III accounts are mainly used for quick payments such as Quick Pass, password-free payment, etc. They can only handle small-amount consumption and payment, and are not allowed to handle other businesses. The household balance does not exceed 1,000 yuan. Category II and III households do not have physical cards. The limits for Type II and Type III accounts are mainly to effectively control customer capital risks.
How to distinguish between Category I new drugs, Category II new drugs, and Category III new drugs?

9. Generic drugs. Which lamps belong to Category I lighting or Category II or III? Which lamps belong to Category I lighting or Category II lighting or Category III lighting?
In the current GB7000.1-2002 standard, lamps are protected against electric shock. The types are divided into four categories, namely Class 0 lamps, Class I lamps, Class II lamps and Class III lamps.
1. Class 0 lamps class 0 lnminaire
Lamps that rely on basic insulation as protection against electric shock. This means that accessible conductive parts of the luminaire, if any, are not connected to protective conductors in the fixed wiring of the installation and are left to rely on the environment in the event of basic insulation failure.
2. Class 1 luminaire
The protection against electric shock of the luminaire not only relies on basic insulation, but also includes additional safety measures, that is, connecting accessible conductive parts to the facility Protective conductors in fixed circuits so that accessible conductive parts are not energized in the event of failure of basic insulation.
3. Class II luminaire
Protection against electric shock not only relies on basic insulation, but also has additional safety measures, such as double insulation or reinforced insulation, but does not have grounding or protection that relies on installation conditions. measure.
IV. Class III Luminaire class III Luminaire
Protection against electric shock relies on the power supply voltage being Safety Extra Low Voltage (SELV), and a type of lamp that does not produce a voltage higher than SELV. Protection against electric shock is an important indicator for evaluating the safety characteristics of lamps. However, previous spot inspections by the General Administration of Quality Supervision, Inspection and Quarantine have shown that the unqualified protection against electric shock of my country's lamps and lanterns products ranks among the top unqualified items in various spot inspections. It can be seen from the standard definition that Class 0 lamps provide the lowest protection against electric shock. In order to ensure that Class 0 lamps can be used safely, the current standards stipulate how to use Class 0 lamps. For example, Article 1.2.21 of the standard stipulates that Class 0 lamps are only suitable for ordinary lamps; Article 2.2 stipulates that lamps with a rated voltage exceeding 250V shall not Classified as Category 0, lamps used in harsh conditions should not be classified as Class 0, and track-mounted lamps should not be classified as Class 0. Class 0 lamps rely on basic insulation as protection against electric shock, and the use environment is restricted to non-conductive locations. However, in actual use, it is difficult for users to identify the types of lamps one by one and whether the use environment is a non-conductive environment. Based on this consideration, the new standard eliminates Class 0 lamps.
