Bagaimana Bola Sepak Diuji

Faktanya, asosiasi sepak bola profesional paling serius di dunia mengharuskan pedoman pertandingan setinggi mungkin untuk menjamin kewajaran persaingan. (Tes Bola Sepak)

Sebuah contoh nyata yang luar biasa dari komitmen FIFA sendiri.

Badan pengawas sepak bola dunia telah mengambil langkah-langkah penting dalam memperbaiki sifat permainan dengan mengembangkan sejumlah model yang digunakan untuk mengevaluasi norma sepak bola di udara terbuka.

Mereka memulainya pada tahun 1996 dengan menghadirkan Program Kualitas FIFA untuk Bola Sepak – yang dimulai untuk mengatur dan meningkatkan sifat penciptaan bola sepak di seluruh dunia.

Namun, mereka tidak puas dengan status quo bahkan dengan presentasi drive ini.

FIFA memutuskan untuk meresmikan peraturan eksplisit yang mengarah pada prinsip-prinsip terbaik untuk bola sepak.

Berikut adalah pernyataan untuk referensi Anda sendiri: (Tes Bola Sepak)

“Semua bola yang digunakan dalam pertandingan yang dimainkan dalam persaingan otoritas yang dikoordinasikan di bawah sponsor FIFA atau konfederasi harus memenuhi persyaratan dan memiliki salah satu karakteristik Program Kualitas FIFA untuk Sepak Bola.

Setiap merek menunjukkan bahwa merek tersebut telah diuji secara resmi dan memenuhi persyaratan khusus khusus untuk merek tersebut yang merupakan tambahan terhadap rincian dasar yang ditentukan dalam UU 2 dan harus didukung oleh Dewan Asosiasi Sepak Bola Internasional (IFAB).”

Apa saja pesanan kualitas bola sepak

Ada tiga tanda otoritas yang diberikan pada bola sepak yang berhasil melewati standar pengujian menyeluruh yang dibuat FIFA untuk penilaian kualitas.

Anda memiliki lisensi yang menyertainya:

Kualitas FIFA Disetujui;
Kualitas FIFA Diperiksa; Dan
Standar Pertandingan Global
Anda dapat melihat bagaimana setiap identifikasi dicari secara menyeluruh pada gambar di bawah ini:

Produsen diharapkan untuk menunjukkan total 7 bola sepak jika mereka mengajukan permohonan untuk mendapatkan status “FIFA Inspected”, sementara mereka harus menyerahkan 10 contoh dengan asumsi mereka memerlukan logo “FIFA Approved” yang lebih banyak dicari untuk dicetak pada bola sepak mereka.(Uji Bola Sepak)

Selain itu, kemampuan “Standar Kecocokan Global” tidak terlalu menuntut dibandingkan dua kemampuan sebelumnya.

Ketika sebuah bola sepak menyelesaikan metodologi pengujian FIFA dan lolos pemeriksaan dengan baik, bola tersebut diberikan tanda nilai berdasarkan seberapa baik kinerjanya selama pengujian.

Misalnya, sebuah bola sepak yang memiliki identifikasi “Disetujui FIFA” di dalamnya harus mengalami kerugian tekanan gas hingga 20% selama sistem pengujian, meskipun kerugian tekanan OK untuk “Diperiksa FIFA” pada dasarnya sebanyak 25%.

Berikut adalah video yang menjelaskan keseluruhan poin dari Program Kualitas FIFA:

Sekarang setelah Anda mengetahui tujuan yang harus dicapai oleh setiap bola sepak, kita harus melihat dengan tepat di area pelaksanaan mana bola tersebut diperiksa. (Tes Bola Sepak)

Komponen bola sepak apa saja yang dicoba

Artikel saya yang membahas apa yang digunakan oleh pemain ahli bola sepak memberikan sedikit informasi kepada pembaca tentang wilayah pameran tempat bola sepak dicoba.

Namun, di sini, saya akan melakukan lompatan yang lebih mendalam.

Lewat sini, ini dia!

1. Keliling

Pada pengujian dasar, tiga bola sepak pertama akan dibentuk dalam rentang waktu 24 jam, setelah itu akan digelembungkan hingga tingkat tegangan tertentu.

Pada saat itu, penilai akan memperkirakan lebar setiap bola di 10 tempat yang ditandai dan melihat apakah angka tersebut sejalan dengan prinsip yang diakui secara resmi.

Untuk tolok ukur “FIFA Approved”, ukurannya harus antara 68,5 sentimeter dan 69,5 sentimeter, sedangkan “FIFA Inspected” hanya memerlukan sirkuit antara 68 dan 70 sentimeter untuk bola sepak ukuran 5.

Mengapa estimasi ini penting adalah karena bola sepak dengan pinggiran yang dapat diprediksi memungkinkan pemain mencapai kontrol yang ideal saat melakukan kontak dan melakukan gerakan seperti menumpahkan.

2. Kebulatan

Selanjutnya kita memiliki kebulatan.

Dalam istilah yang tidak terlalu sulit, apa yang kita lihat di sini adalah bola sepak yang berbentuk bulat dan tahan lama.

Sekali lagi tanpa henti saya telah membahas pentingnya bola sepak berbentuk lingkaran, namun tidak ada salahnya untuk merujuk pada kelebihannya.

Bola sepak yang benar-benar bulat memberi pemain panggung terbaik untuk tampil sesuai kemampuannya.

Karena sepak bola adalah salah satu bentuk hiburan, FIFA percaya bahwa para pengamat harus senang dan bertanya-tanya tentang keunggulan permainan tersebut.

Hal ini dapat terjadi dengan asumsi bahwa bola sepak menunjukkan desain terbang yang masuk akal dan tidak mengejutkan saat berada di udara.

It wouldn’t be a lovely sight to see a player endeavor to bend a soccer ball, just for it to move a couple inches as a result of having an inadequately adjusted figure!

Thus, at this stage the breadth of the soccer ball is estimated after it has been swelled to a tension degree of 1 bar.

The measurement of distance across then happens at the center of 16 boards, and ensuing to that a normal is determined.

Here, the contrast between the least and most elevated measurement figures should not surpass 1.5% for the “FIFA Approved” name, albeit a more prominent breathing space of 2% is given for the “FIFA Inspected” standard.

3. Rebound ability

Thirdly, we have the assessment which covers a soccer ball’s bounce back capacity.

Players must have the option to expect the bearing of a ball, particularly when it skips off of a grass or engineered turf surface.

It would be adverse to the game on the off chance that soccer balls bobbed in a flighty way, as members will wind up confounded and begin re-thinking their own developments on the pitch.

Thus, with this test, a soccer ball is dropped multiple times from a level of 2 meters onto a steel plate.

Utilizing a camcorder, the distance covered when the ball bounce back off of the surface can be recorded utilizing the bounce back level of the underside (lower side) of the ball as the reference point.

For quality principles, the contrast between the most elevated and least bob ought to be something like 10 centimeters separated.

All the more thus, the level, everything being equal, should settle somewhere in the range of 120 and 165 centimeters for a “FIFA Approved” standard, or somewhere in the range of 115 and 165 centimeters for a “FIFA Inspected” quality honor.

4. Water absorption

A soccer ball that is wet shows pretty unique way of behaving from one that has been kept in a dry state.

Assuming you’ve played soccer in the downpour previously, you might have noticed that wet soccer balls tend to:

travel through the air much more leisurely;
have a lower bounce back level while bobbing off of the ground
be more challenging to bend and hit with power
This is where the water retention test comes in, as it guarantees that soccer balls don’t get too weighty when they take up dampness.

Presently, this test is really a really clear one.

Here, a soccer ball is lowered in a water-filled vessel as it is squeezed and turned around various times.

When that assignment has been finished, the ball is then eliminated from the water prior to being cleaned down and yet again gauged.

The weight increment is communicated – in rate terms – by correlation with the first weight of the ball before it was suffocated in, in light of the fact that this is the way the analyzers show up at how much water was assimilated.

To meet the “FIFA Approved” standard, an expansion in weight of something like 10% is required, while the limit for “FIFA Inspected” sits at a 15% weight increment.

5. Weight

The greatness or softness of a soccer ball becomes significant when the part of reliable playing reaction comes to the front.

On the off chance that it is either excessively light or excessively weighty, you can anticipate that it should move with less consistency, particularly while it’s in flight.

In this way, as a component of the testing system here, the example balls are expanded and shown up a standard environment utilizing a breeze safeguarded electronic equilibrium, that keeps any mistakes from influencing the consequences of the information being gathered.

“FIFA Approved” loads rest somewhere in the range of 420 and 445 grams, while figures should be somewhere in the range of 410 and 450 grams for the “FIFA Inspected” mark.

6. Loss of pressure

The 6th test is about soccer balls losing air.

A playing experience can be adversely impacted in the event that a soccer ball loses gaseous tension moderately rapidly, with components of the game becoming flighty and conflicting subsequently.

For example, it would be substantially more challenging for members to make long passes and profound crosses with a soccer ball that needs adequate air amount.

The ball is probably going to fizzle at arriving at its expected objective, halfway on the grounds that it in all likelihood won’t go through the air quickly enough or sufficiently high.

As a feature of this test, a soccer ball is swelled to a characterized pressure level and left to rest for 3 days.

After that period has passed, an overseer will take its pneumatic stress estimation to work out the level of air lost over the course of that time.

For a “FIFA Approved” standard, a limit of 20% misfortune in pressure is permitted, though the “FIFA Inspected” level considers a limit of 25%.

7. Shape and size retention

The last test is just completed on “FIFA Approved” soccer balls.

The reason behind this one is that a soccer ball ought to be in a similar execution state toward the finish of the game as it was in toward the start.

As the normal match includes roughly 2000 kicks of a soccer ball, a test is made to recreate such a climate to see if the ball being referred to can hold up to the afflictions of a cutthroat match.

When the soccer balls are expanded to a predefined pressure level, they are advanced rapidly by two pivoting chambers which turn the balls at a specific speed.

During this cycle, the soccer balls hit a steel outline ceaselessly at speed and points that are predictable.

After 2000 “hits” the chambers are halted from turning the balls and afterward any expansions in circuit or contrasts in generally sphericity are estimated.

To breeze through this assessment, soccer balls should likewise come out solid with valve openings that give no indications of harm and it is as yet unblemished to join that.

Furthermore, here are the exact metric qualifiers:

Expansion in boundary – limit of 1.5 centimeters permitted
Roundness deviation – limit of 1.5% permitted
Change of strain – greatest reduction of 0.1 bar permitted

Where is the soccer ball testing conducted?

To go through such a requesting quality assessment process, offices with the furthest down the line mechanical hardware should be made accessible for analyzers.

Indeed, the wizardry is said to occur at EMPA Materials and Science Technology – which is a Swiss government lab for materials testing and exploration that is situated in St. Gallen, Switzerland.

Untuk alasan apa bola sepak harus dicoba

Soccer ball testing is perfect for planned purchasers since they don’t need to stress over buying a ball that would give them significant issues further down the existence cycle.

FIFA’s trying methods nearly ensure quality since you are choosing a ball that has formally been endorsed for play because of the intensive exhibition testing it has gone through.

This wasn’t true before FIFA imagined their quality program.

Various producers made soccer balls that differed enormously in quality from each other, and there was a great deal of vagueness on the lookout, as purchasers didn’t know whether they would need to return a recently bought ball in a couple of days or whether it would keep going for two or three years.

In this regard, things have surely been made more straightforward because of soccer ball testing.

Shutting contemplations

That finishes my article on how soccer balls are tried!

Ideally you will have gotten pieces and snippets of data that can illuminate your own decision making when you need to purchase a soccer ball.

Furthermore, coincidentally, assuming you really want assistance with that cycle, I’d propose you look at our total purchasing guide on the best soccer balls, as it’s an extraordinary beginning stage for unpracticed purchasers.
