Measurement method Principles of authentication

Hello. It is a hori of the manager.

Although it is not in the title of this site, there is a law under the jurisdiction of the Ministry of Economy, Trade and Industry called the Measurement Law along with PSE, PSC, etc.

From the viewpoint of general distribution, the measurement method has the impression that it is a little maniac law compared to PSE etc., but its history is much older than PSE (electrical appliances) etc., and in Japan, the origin is 701 Daiho Ritsu Rei it will go back to.

The act of measuring the length, quantity, weight, so-called weight and measure, etc., is indispensable in our lives, for example, water supply, gas, electricity usage, refueling at gas stations, weighing of foodstuffs, thermometers for health management, sphygmomanometer, scale, etc.

In addition, there is a measuring instrument used for air pollution measurement to watch over the environment, and the act of "haling" has a close relationship with daily life.

Currently, there are the following units of measure in the world.

There are many units that we are used to hearing, such as length: meter, mass: kilogram, time: second, current: ampere, but for a moment, it is amazing that these units are unified in the international community.

For example, the metric standard (unit) was established in France at the end of the 18th century with the aim of establishing a unified unit system that can be used universally.

To be a little more specific about metric, it is a decimal system of units based on the units of length, meters (French: mètre) and kilograms (French: kilogramme), which are units of mass.

As the background to the creation of such standards, it would have been good if the units were unified only in that country and region while the scope of human action had been limited until then.

However, as the scope of human action has expanded and commerce and other transactions have been conducted between internationally, inconsiscies in units have become a major problem.

At that time, Japan, which was in the Edo period, naturally used a different unit, but one of the reasons why japan was rapidly internationalized among Asian countries due to the Meiji Restoration was that it was the first to switch the units to the international standard.

On this site, the explanation of the system is omitted as much as possible about the target authentication, and it is written emphasizing how to authenticate.

However, with regard to the measurement method, if we do not roughly understand the history of weighing (weights and measures) that are the premise, I think that we cannot understand why this law is so complicated.

To be clear, if you try to write maniacly, you can write as much as you want, but from the perspective of a business person, I will tell you enough contents that you should know.

In addition, if you are viewing this page and importing and selling products related to weighing, it will be mainly household specific weighing instruments (general scales, infant scales, cooking scales).

I will write about the authentication method next time.
This time, I will briefly explain the history of the measurement method.

A rough history of weighing (world history)

Quote: Tokyo Metropolitan Metrology Laboratory_Exploration! The World of Weighing_History of the 4th Measurement System

I looked at some of the materials, but there are some tables like the figure above, and they are very neatly organized, so I quoted them.

It is said that it was more than 10,000 years ago that humans originally started "hare" though it is said that it is as described above as a historical fact (record). In the beginning, for hunting, gathering, and farming, it seems that the moon was full, the width of the fingers, and the amount scooped by the hand, etc. were used.

At that time, it is presumed that human beings were weighing only in each region without interaction or trade with other regions.

And time went on, and the method of weighing evolved from one to another. And in the world of weighing, a revolutionary event occurs in human history.

Qin's First Emperor

The first emperor of Qin is currently famous for the manga "Kingdom" serialized in Young Jump. The manga is drawn from the perspective of the first emperor, but in history his evaluation (merit and demerit) is greatly divided.

On the other hand, on the other hand, there are some originals in the business he conducted today, more than 2,000 years later, and from such a point of view, it can be seen that he was still a tremendous person.

One of the businesses is the unification of money, weights, etc.
Until the unification of the Qin Dynasty, China was called the Spring and Autumn Warring States Period, and seven countries were fighting for supremacy: Qin, Chu, Chin, Yan, Zhao, Wei, and Han.

At that time, there were original money and weights and measures in each country, but by unifying them, power was unified.

This is an important point, and in short, there is a logical development that by unifying things that are closely related to life, unnecessary accidents and conflicts are eliminated, communication between people who use it becomes active, and leads to national land peace.

I personally feel that this is the origin of the system called "certification", which is still alive today. National unity begins with the unification of weights and measures.

Here's what you've actually done:

The bronze coin issued by each country in the warring states issued the unified currency of half-coin because the one circulated such as cloth coin, sword coin, and yen was different. Moreover, the step of the unit of length (degree) was first defined as six shakus in the weight and measure, and the standard instrument of "Measure" (Qin Gon) which measured "Masu" (Qin amount) and weight (weight) which measured the amount was manufactured and distributed to the whole country. (Omission) Also, "Car gauge" was unified, and the wagon was made to be able to run by the same rut (The gauge of the railway car was unified if it said in the present age, and jr and the private railway were able to run the same train though a concrete width etc. were not known).
Quote: Window of the World_First Emperor

Metric

As I mentioned earlier, it is a unified unit system for length (meters) and weight (kilograms) born in France at the end of the 18th century.

The contents themselves are very heavy and long, but I will o'o'm over the origins because they are a little off from the purpose of this time.

Measurement Methods in Japan

Daiho Ritsu-rei

In 701 A.D., textbooks are the first national governance system established in Japan led by Emperor Bunmu at the time.

In the background, in the international situation in East Asia, which is tense, such as the destruction of neighboring Baekje, It was necessary for Japan (japan at that time) to maintain its independence as a nation by promoting centralization and stabilizing the government.

While various laws were enacted for national unification, the system of weights and measures that had fallen apart in various places until then was unified.

This is the beginning of the current "measurement method" in Japan.

Using measuring units and measuring instruments based on the measure-kan method originated in China, and the measurement system also established a weights and measures system modeled after the rule-of-law system of Tang Dynasty.

As a result, taxes, money, and land systems, which form the basis of the nation, were established.

Taiko Checkpoint

It refers to the farmland checkpoints that Toyotomi Hideyoshi, who became taiko during the Azuchi and Momoyama period, where the Warring States Period ended, went nationwide.

I will omit the details of the system, but to put it broadly, we aimed at further stabilization of the nation that we united the whole country by arranging the rights of land and unifying the units that were disjointed in various places at that time.

I quote wikipedia for the significance of the checkpoint.

Accurate information which becomes the basis of the system afterwards such as the approach benefit to not only the innovative meaning that the arrangement related to the right relation and the unit union was aimed but also the eximation of the tribute to the farmer, the femist, the vassal, the military service imposition, and the family case, etc. is centrally concentrated and understood, and the meaning is large.
Citation: wikipedia_ Taiko Checkpoint

Easily review the significance of the measurement method

It is weights and measures to be able to be called the basis of the maintenance of the legal system to the union of the nation though it has seen in the first emperor of the Qin, the Great Treasure Ritsu rei, and the Taiko public prosecutor's office, etc.

As you can see, for example, what Mr. A weighed is 500 g, while what Mr. B weighed is 1 kg. In addition, mr. C is 1m if it measures, but Mr. D is embarrassed because it is 1.2m.

There is a history of unifying it as a nation because a useless fight is born from such a place, and it becomes a obstruction of a smooth business act.

And the times flow, and the unification comes to advance not only by one country but on a world-by-world basis.

Internationalization in Japan from the Viewpoint of Measurement Law

Accession to the Metric Convention

There is a very easy-to-understand explanation without summarizing it, so I will quote it as it is.

Let's take a look back at the measurement system of modern Japan since the Meiji era. In 1875, when the weight control ordinance was promulgated, the M2 Treaty was established in France, and Japan joined in 1885 (Meiji 18), and in 1890 (Meiji 23) received the meter prototype and kilogram prototype at the same time as western countries. It was fortunate that Japan was able to shift to the metric system without sticking to the traditional shakukan method, and there was a measurement system of japan's measurement system modern Japan until the Edo period in the age of the revolution called Meiji Restoration. It can be said that one of the foundations on which Japan has become a technological power is that japan's modern measurement system has progressed along with the metric system.
Quote: Tokyo Metropolitan Metrology Laboratory_Exploration! The World of Weighing_History of the 4th Measurement System

There is maintenance etc. of such a law in the background though the expansion, etc. of the wealthy country and strong army and the armament, etc. can be roughly talked about when saying the modernization of Japan, too.

There is a system construction such as placing the tae masanori as a central government which summarizes the state power with the enactment of Constitution of Japan as a famous place that everyone knows, and dividing the power of the tae-kan into three powers of legislation, the administration, and the judiciary, but more concretely, the metric system adoption etc. exist.

Dissatisfaction in various parts of Japan

However, on the other hand, it seems that dissatisfaction and resistance by the common people in Japan remained quite strongly in Japan, especially in response to the fact that the unit of measure that we have used so far, for example, shaku, kan, monme, etc. can not be used.

If what we have been using in business etc. suddenly changes direction, it is natural for anyone to state an objection.

If you think so, I think the Meiji government at that time was quite radical, and it can be said that it had a passion for internationalization that much.

The government has since suppressed the persistent opposition in Japan, but it is not completely prohibited, so it seems that there are still people who do measurement notation from ancient Japan among individuals, and some tools that are easier to use with such notation.

Enactment of the Metric System

If you trace the detailed history, it will become as fine as you can again, so I will quote the material of the Tokyo Metropolitan Metrology Inspection Office that is neatly settled again.

Subsequently, in 1891, the Metric Law was promulgated in accordance with the Western measurement system, and in 1951, after the end of World War II, the New Constitution and local autonomy law was enacted, and a democratic and rational new measurement system was launched by promulgating the "Measurement Act" adapted to changes in the social and economic environment from an international perspective.
Quote: Tokyo Metropolitan Metrology Laboratory_Exploration! The World of Weighing_History of the 4th Measurement System

To add a little, in 1959 (Showa 34), except for the tsubo notation of land and buildings, the metric system was fully implemented, and on April 1, 1966 (Showa 41), the metric system was finally fully implemented.

By the way, in 1959, stamps commemorating the full implementation of the metric system were released, and the government's desire to conduct metering administration is transmitted.

Since then, there seems to have been a persistent opposition to the government's unisternal measures, but we have overcome them and have reached the current quantitative administration.

Quote: wikipedia_ Metric

To be honest, it is difficult to sell products subject to the Measurement Act.

We have seen the history of the measurement method at a fast pace, but it is a law that has a long history and repeated government intervention, and it is difficult for general operators to enter the law so that PSE, PSC, Radio Law, etc. look cute.

Frankly, there are many other things that can be sold even if you do not force yourself to choose products related to the measurement method.

However, it is not impossible to enter the market, so please wait for the next article on obtaining the measurement method.

Lastly, I would like to say that we aim to facilitate communication by unifying weights and measures, but even so, human beings have been repeating wars and conflicts.

That said, then, if it was useless, there was never such a thing, and I think that it is still the wisdom of the person who always tries to move forward.

By the way, a lot of concession exists in the beautiful name that this measurement method is the basis of the nation in Japan, and such a doubt comes from man in the standpoint of the outfield honestly whether the measurement examination place etc. in each prefecture are really necessary, too.

However, I can't help but say this, and I think it is very important to understand such a system in order to authenticate that law.
