What does the 6 level needle check refer to, and what does the 3 check system in the project refer t

Over-inspection needle: In order to detect the defects in the manufacturing process of clothing and accessories in a timely manner, the inspection of metal substances that cause injury to customers is called over-detection needle. Clothing exported to Japan, Europe and the United States and other countries have this requirement, there is no specific standard at present, the use of needle detectors is different, the level of needle detection is also different.

What items should not pass the needle: All products containing ferromagnetic metals (cobalt, nickel, iron) with a certain content cannot pass the needle detector inspection. Such as:

If the purity of larger zinc alloy buttons and copper buttons does not reach a certain standard, they will not be able to pass the inspection of the needle detector. Some of the iron metal components contained in the electroplating of buttons cannot pass the needle detector. Over-detection needle level:

There are four levels of needle detection, six levels, eight levels, and ten levels. The sensitivity level of the needle detector is usually determined by the scale on the needle detector sensitivity knob. When the scale or sensitivity indicator is adjusted to 8, it is called level 8.

However, due to the inverse proportion of the height and sensitivity of the needle detector channel, the sensitivity of the needle detector will be different depending on the height of the needle detector gantry. Take the Sangko brand 630 luxury conveyor needle detector as an example. When the sensitivity indicator is adjusted to 8, the 12 cm channel height nine-point test card can detect the FE diameter standard test card.

The 15cm channel height needle detector nine-point test method can only detect the FE diameter standard test card, and the 20cm channel height needle detector can only detect the FE diameter standard test card! It can be seen that the level cannot be generalized!

In fact, in the field of clothing needle inspection: this six-level needle inspection statement is wrong! Because the needle detection capacity of each manufacturer, each model, and each model of needle detector is different.

Therefore, the correct statement is that the needle detection requirement is how big the needle is, and the highest needle detection requirement in the entire clothing industry is the needle detection requirement for infants or underwear (that is, to catch the broken needle below the diameter). Those below this level can no longer be considered. The other thing is

5, even bigger, and more!

Self-inspection, mutual inspection, special inspection.

The specific introduction of the three inspection systems is as follows:

1. Self-inspection: The operator must conduct self-inspection according to the quality requirements of the corresponding sub-project during the operation, and can continue the construction only after acceptance by the team leader. The constructor should supervise the team leader to self-inspect, create self-inspection conditions for the team (such as providing relevant equipment, assisting in solving testing tools, etc.), and conduct intermediate inspection of the operation quality of the team.

Second, mutual inspection: mutual inspection between types of work, after the completion of the previous process before the construction of the next process, the team leader should carry out the handover inspection, fill in the handover inspection form, signed by both parties, before entering the next process. After the finished product is produced in the previous process, the finished product protection procedures should be handled in the next process, and then the unit of the next process shall bear the responsibility for the damage, pollution, loss and other problems of the finished product.

3. Special inspection: All sub-projects, hidden inspections, and pre-inspection projects must be invited to conduct quality inspection and evaluation according to the procedures and as a process.

The three-inspection system in the project refers to self-inspection, mutual inspection and special inspection.

Self-inspection means that the producer inspects the products he produces in accordance with the technical standards specified in the drawings, processes or contracts, and makes a judgment on whether he is qualified.

Mutual inspection is that production workers inspect each other. Mutual inspection mainly includes: the next process conducts sampling inspection of the products transferred from the previous process; Mutual inspection of the same machine tool and the same process shift handover; The quality officer or team leader of the group conducts random inspection of the products processed by the workers of the group.

Special inspection is an inspection carried out by professional inspectors. Professional inspection is an objective requirement of the division of labor in modern large-scale production, and it cannot be replaced by mutual inspection and self-inspection. Moreover, the three-inspection system must be dominated by professional inspection.

The three inspections of the project refer to the first is the supervision inspection, the second is the construction inspection, and the third is the completion inspection.

The three inspections in the project are self-inspection, mutual inspection and final inspection.

Three inspection system for project quality.

1. Self-inspection of the construction unit: The operator must conduct self-inspection according to the quality requirements of the corresponding sub-project during the operation process, and can continue the construction only after being accepted by the team leader. The constructor should supervise the team leader to self-inspect, create self-inspection conditions for the team leader (such as providing relevant equipment, coordinating and solving testing tools, etc.), and conduct intermediate inspections on the operation quality of the team.

Mutual inspection between types of work, after the completion of the previous process before the construction of the next process, the team leader should carry out the handover inspection, fill in the handover checklist, and sign by both parties before entering the next process. After the finished product of the previous process, the finished product protection procedures should be handled for the next process, and then the unit of the next process shall bear the responsibility for the problems of damage, pollution and loss of the finished product. The chief engineer of the project and the quality inspection department are responsible for reporting to the supervision team for inspection.

Second, the supervision group sampling: the construction unit to submit the application for inspection, first by the contractor to fill in the inspection form, there are on-site supervision personnel to check and approve the signature of the transfer to the experimental supervision personnel for testing, the test results reported to the test engineer for approval, and then confirm that the qualified report to the resident supervision engineer or the bid supervision engineer to sign and agree to enter the next process of construction.

3. Owner or quality supervision station inspection: the supervision team must do a good job of ledger registration of qualified construction sections, levels, parts, etc., and the owner or quality supervision station must provide irregular inspections, and actively assist in quality inspection to ensure the smooth development of various inspections.

English at university.

In the 4th and 6th exams, "brush scores" refer to those who have passed the university English.

Level 4 and 6 exams, people who feel that their scores are not high enough; Continue to take the test and aim for a higher score.

CET-4, abbreviation for College English Test Band 4, is a national English test administered by the Department of Higher Education of the Ministry of Education of the People's Republic of China. The main target of the examination is junior college, undergraduate or graduate students who have completed CET-4 according to the syllabus. College English.

Preparations for the standardized tests for grades 4 and 6 began at the end of 1986 and were officially implemented in 1987.

The purpose of CET-4 is to promote the implementation of the college English syllabus, to measure the English ability of college students objectively and accurately, and to improve the teaching quality of college English courses in China. Commissioned by the Ministry of Education of the People's Republic of China, "National College English.

Level 4 and Level 6 Examination Committee" (before 1993 it was called "College English.

Level 4 and 6 Standardized Test Design Team) is responsible for the design, organization, management and implementation of college English.

Level 4 and 6 exams.

The "brush score" in CET-4 and CET-6 refers to those who have already passed CET-4 and CET-6 and feel that their scores are not high enough; Continue to take the test and try to get a higher score.

It means that you have passed the exam (achieved a passing score of 425 or above), but are not satisfied with this result, and continue to register for the test to get a higher score. This is called "scoring".

1. The current grade 4 and 6 exams only have one transcript, which will have the results of each section and the total score. If your score in level 6 is not very high, you can try to take it again, especially if you want to take level 4 or 6 oral speaking, level 4 is not necessary. Because the Level 4 and 6 speaking test must have a score of 550 or above in Level 4 (including 550 points) or a score of 520 or above in Level 6 (including 520 points).

2. CET-4 refers to students who have passed CET-4 and re-register for CET-4 in order to improve their CET-4 scores.

3. After the annual examination in August or September, the results will be announced and the transcript will be issued, according to the regulations of the Ministry of Education, the fourth and sixth grade examinations do not set the passing line, and the fourth level 425 points (including 425 points) or more can apply for the sixth level, so it is generally believed that the passing line of the fourth and sixth grades is 425 points. The score of English 4 and 6 is a ranking score, and there is no overall score.

4. Registration time: CET National English Test Level 4 and 6 test time: June and December each year (the time is slightly different every year).

It refers to a higher score in the college entrance examination after 425 points (it is generally believed that 425 points are passed the fourth or sixth level).

Brushing points is to get a high score certificate.

The high score for level 4 is 550 and the score for level 6 is 520

If you pass 520 points in English level 6, you will have a high score, and you can take the speaking test if you pass 520, and you don't need to brush up on the score again.

Extraction code: 1234 Introduction: CET-4 and CET-6 is a national English test supervised by the Ministry of Education, whose purpose is to objectively and accurately measure the actual English ability of college students and provide assessment services for college English teaching.

1. When starting the needle detector, it is necessary to ensure that it is stable before putting in the item, and the detected object cannot touch the probe, otherwise it will easily lead to false alarm and alarm.

2. During the operation of the needle detector, the vibration of the instrument should be avoided, and the items should be placed lightly, and there should not be any small iron parts moving around the instrument, such as carts, forklifts, etc.

3. Pay attention to the adjustment of the deviation belt in the operation of the needle detector, when the conveyor belt is biased to the right, it means that the right side is pulled tightly, and the hexagon wrench can be used to slowly loosen the adjusting screw on the right; It should be noted that as long as the conveyor belt does not catch the retaining rings on both sides, it does not need to be adjusted, and it should be careful and consciously adjusted when adjusting the deviation, which can last for a long time without deviation.

4. After each power on, it is necessary to use the standard test block to conduct experiments in various positions of the conveyor belt, if there is no alarm, it means that the needle detector is abnormal. After each inspection of food or clothing, a standard inspection block is used to ensure that nothing is lost.

5. In order to prolong the service life of the needle detector, the power supply should be disconnected after each use, and the instrument should be cleaned, and the needle detector should be covered with a protective cloth.

This depends on the machine you bought, sensitivity, if the machine is ***, some sensitivity can hit level 6, some to level 9 level 10, some simply do not adjust the sensitivity, after leaving the factory is fixed (these according to the 10-level adjustable sensitivity needle detector), if you are an old machine, contact the manufacturer, ask them to change the computer version, if you have used it for many years, you need to change the magnet, (personal advice, if you need to change 2 things, you can consider buying a new one), Tell the manufacturer about the situation, call them to come over for maintenance, or it should be fine under the guidance of **.

Carbide means carbide. This word is used to represent cemented carbide. Its main ingredient is tungsten carbide. The most common piece is used as a drill, cutter, and screwdriver bit.

It is classified according to different uses.

C-6 is a hierarchical classification that falls under the American ANSI.

ANSI stands for American National Standard Institute. But it is not an organization of the state, but an organization that arranges agreements and standards within the industry. Therefore, it is a common standard in the Americas.

C-1 to C-4 are for cast iron, and non-ferrous and non-metallic materials C-5 to C-8 are for steel and steel alloys.

C-9 to C-11 are for abrasive surfaces.

C-12 through C-14 are for collisions.

C-15 to C-19 are various other uses.

It is used in grades of steel and steel alloys.

C-5 is a grade with better toughness and suitable for coarser uses, and C-6 is a grade for general use.

C-8 is a relatively high hardness and is suitable for more precise applications.
