Measurement method Principles of authentication
この記事は約 25 分で読めます。 8 Views

Hello. It is a hori of the manager.

In the previous article, I briefly explained the history of the weighing method.

This time, I would like to write about how to specifically certify the measurement method.

As I mentioned in the previous article, if the person viewing this page imports and sells products related to weighing, I think that it will be mainly a household specific weigher (general scale, infant scale, cooking scale).

The reason is that home specific measuring instruments can be sold at general retail, and from real stores such as home appliance mass retailers, it is possible to sell them on e-commerce sites such as Amazon.

Other measuring instruments, for example, may fall under medical equipment if they measure body temperature and heart rate, and there are many things that do not know where they are selling measures for business use, and there are things that do not become business unless you secure a sales channel from the beginning.

In addition, if it is said that all those weighing fall under the measurement method, the range of kilograms to be weighed and the target determine whether or not they are applicable.

For example, it is a luggage checker that is often seen as travel goods, but this is not subject to the Measurement Act because there are no standards that conflict with the Measurement Act.

This time, we will take up a household specific measuring instrument (general scale, infant scale, cooking scale), which is a product subject to the measurement method that can be general retailed, and explain the measurement method certification.

In addition, although it is not directly related to certification, I will introduce the article of Article 9 of the Measurement Act as useful information.

Article 9 (1) Measuring instruments used for weighing the amount of the state of the object listed in Item (i) of Paragraph (1) of Article 2 with a scale or notation by non-statutory units of measure shall not be sold or displayed for the purpose of sale. The same shall be the same for measuring instruments with scale-of-measure by units of measure specified in Cabinet Order set forth in Article 5, paragraph (2) and other than those specified by an Ordinance of the Ministry of Economy, Trade and Industry for use exclusively for special weighing specified by Cabinet Order set forth in the same paragraph.

This prohibits, for example, the sale or display of a measure with an "inch" scale display or a measuring instrument with a "pound" scale display for the purpose of selling or selling. If you violate, you will be fined not more than 500,000 yen.

The mechanism of penalties is similar to PSE, PSC, etc. around here.

If you look closely, there are exceptions, but basically, if you are not familiar with the measurement method, do not sell measuring instruments other than meters and grams.

You may think that such a thing is not sold in the first place, but for example, pound display is not prohibited in China.

If you import a measuring instrument displayed in pounds from China and sell it as it is, there is a possibility that it will be subject to penalties, so be careful.

This time, I will talk about the "general scale", which is the most familiar among men and women of all ages among household specific measuring instruments.

What are the standards for household specific measuring instruments?

I think that it is easier to understand if you quote the page of the Ministry of Economy, Trade and Industry as it is.

A household specific measuring instrument is mainly used for the life of general consumers, and the amount of eyes Note 1) is 10 mg or more and the number of scale labels Note 2) is 100 or more non-automatic scales Note 3), and the following conditions are met.

General scale
Amount of hail Note 4) exceeds 20 kg and is a non-automatic scale of 200 kg or less, and used exclusively for weighing weight

Infant scales
non-automatic scales having a hail volume of 20 kg or less and weighing the weight of infants exclusively

Cooking scale
Non-automatic scales with a hail volume of 3 kg or less and weighing the mass of food exclusively during cooking

Note 1) Eye volume: The minimum digit number displayed on the measuring instrument. When the minimum digit is displayed as 0,1,2,3,4:9 g, the eye volume is 1 g.
Note 2) Number of scale signs: Figures calculated by dividing the amount of hail by eye volume.
Note 3) Non-automatic scale: Instead of continuously measuring automatically, the scale is to measure in a stationary state.
Note 4) Hail amount: The maximum mass that can be metered.

Citation: Ministry of Economy, Trade and Industry_Regulation of household specified measuring instruments (Articles 53 to 56 of the Act)_What is a household specified measuring instrument?

As I wrote in the previous article, the weighing method promises to produce the same measurement results no matter who goes.

For example, Mr. A, who weighs 60 kg, should not be displayed as 60 kg on the scale of B, but 65 kg on the scale called C.

On the other hand, cooking scales are stipulated to be up to 3 kg or less, but for example, measuring instruments mainly used in kitchens that can weigh up to 20 kg may not be subject to the measurement method.

This is because there are few cases where 20 kg is weighed in domestic cooking, and it is not suitable for measuring the amount of fine hail required for cooking in the first place. This is because most of these are used for commercial use (mainly in the kitchen, etc.) for reference purposes that weigh roughly.

This is the opinion heard directly from the measurement test office of the municipality.

What other measuring instruments are there?

Water, gas, electricity usage, refueling at gas stations, weighing of foodstuffs, thermometers for health care, sphygmomanometer, etc.

For example, in an easy-to-understand place, a test is necessary for a measuring instrument that weighs letters at post offices, etc., and a measuring instrument that weighs grams of meat at a butcher shop.

The reason is that if there is a deficiency in the measuring instrument that charges due to weight, the operator using it may cheat.

However, since the measurement of such measuring instruments does not appear in the retail world, details are not included on this page.

About certification procedure

The Ministry of Economy, Trade and Industry (METI) When importing a household specific measuring instrument, 2. When selling only household specific measuring instruments, 3. Three patterns when manufacturing a household specific measuring instrument are exemplies, but first, 2. It will not be possible.

To be honest, there's no benefit to doing it. It is also 3. is a pattern of manufacturing in Japan, but if you are looking at this page, you will not manufacture in Japan. It is unprofitable.

Then, 1. 1. will only be imported, so write in a little more detail, 1. and 3. It will be a combination technique.
Reference: Ministry of Economy, Trade and Industry_Regulation of household specified measuring instruments (Articles 53-56) _Outline of regulations on specified measuring instruments for home use

The simple flow from import to sale is as follows.

When importing and selling household specific measuring instruments, they must comply with technical standards (JIS B7613:2015)*1), and by the time they are sold, they must be indicated that they meet technical standards (so-called round marks note 2).).
Note 1) The technical standards for specified measuring instruments for home use are permitted to comply with JIS B7613:2008 until December 31, 2016. Note 2) Round mark: It is the following display, and it is necessary to display it in a place where the diameter is 8 mm or more and the product is easy to see.

Citation: Ministry of Economy, Trade and Industry_Importing Household Specified Measuring Instruments_To Importers


"~~When selling, it must conform to technical standards (JIS B7613:2015), and ~~" means that authentication inspection must be done.

In addition, as will be described later, the common name: Marusho mark must be displayed on the general scale etc.

Round mark

This area is the same as PSE, PSC, etc.

In addition, it will be produced at a factory in China (overseas),
As a precaution when producing a measuring instrument,

When manufacturing a household specified measuring instrument, it is necessary to notify the Minister of Economy, Trade and Industry in advance via the prefecture having jurisdiction over the location of the main factory or workplace. For more information, please contact the prefecture where you have jurisdiction. You can check the contact information of the prefecture that the location has jurisdiction over in the list of metrology offices (prefectures).
Citation: Ministry of Economy, Trade and Industry _When manufacturing a household specified measuring instrument_Notification of manufacturing

You need to.

In addition, as penalties for violations of various measurement laws,

・ Those who did not report the manufacturing business: Fine of not more than 300,000 yen
・ Those who violate the improvement order: Fine of 500,000 yen or less
・ Those who sold without displaying the marusho mark: Fine of 500,000 yen or less

Please note that there is a problem.

Inspection contents

If you search by "JIS B7613:2015" described above, the inspection contents etc. are displayed.

However, even if all this is read, it is not so meaningful for the business operator to understand from 1 to 10 because it is necessary to let the inspection organization do it further.

Here are a few typical items.

The most important thing in measuring instruments such as scales is to accurately display the weight under any situation.

In the general scale, weights of up to 200 kg class are weighed with Zdorn and Zdorn on a basis of thousands of times.

It does so to check to see if the correct weight is displayed.

By the way, in the general scale of digital display, the tolerance of the weighing range from 0 kg to 65 kg is ±200 g, and the tolerance of 65 kg or more is up to ±300 g.

This is quite amazing, for example, speaking of 300 g ± at 100 kg, there is only an error of 0.3%.

Once we certified a Chinese scale manufacturer, there were 2 to 3% error, so it was a good opportunity to know how loose the standards were made and the accuracy of Japanese weighing methods.

Inspection cost

As you can see if you look at the inspection contents in JIS B7613:2015, the types are very diverse, and each requires inspection equipment, and as far as we know, inspection institutions in Japan cannot respond in one place alone.

It will straddle multiple inspection agencies, and the cost will exceed 1 million yen. If you have any doubts, you can check it out. There are so high hurdles to measurement law certification.

In addition to costs, there may be few companies that have the technical capabilities to successfully use multiple inspection organizations.

On the other hand, how health equipment manufacturers are inspecting, according to the information they hear, they seem to have their own inspection institutions, and they have accumulated the know-how and equipment necessary for them.

After all, the reason why there are only major health equipment manufacturers is that inspections can not be done unless they are major companies.

However, we have know-how on measurement law certification in China, and we have actually authenticated our customers at the individual level. The cost is also quite reasonable, so if you are interested, please contact us.

After all, if the contents of this page are collected on the Internet, it is possible to summarize roughly, but in the end, it is not necessary to take a story to the inspection agency, and in most cases it will eventually consult with us.

About displaying round marks, etc.

The display of the household specific measuring instrument is very severe, and the display of the importer name (seller name), product name and model, production number, year of manufacture, measurement range and eye volume, type and number of batteries, contact information (telephone number, e-mail address, address) of the window, and round mark are required.

It is a little old, but it is a photograph of the scale in the office.

The battery display is listed else than else.

These indications must also be included in the packaging box and instruction manual, making them very strict.

About the flow after authentication

This is also quoted from the Ministry of Economy, Trade and Industry page.

The business operator who imported the household specified measuring instrument must report the total number of imports (including the type and major importing countries) for the previous year to the prefectural governor having jurisdiction over the location of the main business site by April 30 of the following fiscal year. For details, please contact the prefecture that has jurisdiction over your location. You can check the contact information of the prefecture in charge of the location in the list of measurement tests etc. (prefectures)

I feel how strict the law is that it is necessary to report even after selling, but it is a gingy world, but on the other hand, it can be said that it is a big business opportunity if you can enter here through regular procedures.

In addition, as with pse, PSC, etc., there is a post-distribution inspection (trial test) by the Ministry of Economy, Trade and Industry for household specific measuring instruments, so products that have not undergone formal procedures may be discovered and subject to penalties.

In addition, you will see Chinese operators selling scales on Amazon etc., but it will definitely be illegal. Because the Chinese business operator will not be able to clear the measurement method in any way.

To be honest, there will not be many operators who enter the Measurement Act, but at least I wanted you to know the national system of measurement law, and if you are interested, you can contact us directly.

Until now, the world was monopolized by some operators, but I think that the number of entrants will increase in such a part eventually.

The world of weighing is so deep that it can not be written on this page, but for businesses that sell home specific measuring instruments, I wrote it as minimum information for certification.

We hope that this content will be helpful when certifying a household specific measuring instrument.
