еталон <i>е</i> килограмът. Същевременно промени в масата на Международния еталон могат да бъдат открити, сравнявайки неговата маса с тази на неговите официални копия по света – това е рядко извършвана процедура, наричана „периодична проверка“. Такива проверки са правени три пъти в историята – през 1889, 1948 и 1989 година. Например Съединените щати притежават четири Pt–10Ir еталона, два от които, K4 и K20 са от оригиналната серия от 40 копия, изработени през 1884 година. K20 е определен за основен национален еталон за маса на Съединените щати. Тези два еталона, както и еталоните на другите страни по света, периодично се изпращат в Международното бюро за мерки и теглилки за проверка, като се транспортират изключително грижливо. През 1984 година K4 и K20 са пренесени на ръка в пътническите кабини на два отделни граждански самолета. </p><p>Трябва да се отбележи, че нито едно копие не е с маса, точно равна на тази на Международния еталон – масите им са калибрирани и документирани чрез отмествания в стойностите. Например основният американски еталон K20 първоначално (през 1889 година) има официална маса от <span style="white-space:nowrap;">1 kg − 39</span> μg), т.е. е с 39 µg по-лек от Международния еталон. Проверката, извършена през 1948 година показва маса от <span style="white-space:nowrap;">1 kg − 19 µg</span>. Последната проверка от 1989 година показва маса, точно равна на първоначалната стойност от 1889 година. За разлика от тези разнопосочни промени, масата на американския контролен еталон K4 постоянно намалява спрямо Международния еталон, като причината за това е известна. Контролните еталони се използват много по-често от основните и са подложени на надраскване и други форми на износване. K4 първоначално има официална маса от <span style="white-space:nowrap;">1 kg − 75 µg</span> през 1889 година, но към 1989 година официално е калибриран до <span style="white-space:nowrap;">1 kg − 106 µg</span>, а десет години по-късно е <span style="white-space:nowrap;">1 kg − 116 µg</span>. За период от 110 години K4 губи 41 µg спрямо Международния еталон.<sup id="cite_ref-Jabbour200125&#32;–&#32;46_26-0" class="reference"><a href="#cite_note-Jabbour200125&#32;–&#32;46-26"><span class="cite-bracket">[</span>26<span class="cite-bracket">]</span></a></sup> </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/%D0%A4%D0%B0%D0%B9%D0%BB:DeviationsFromIPK.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/d/d0/DeviationsFromIPK.svg/220px-DeviationsFromIPK.svg.png" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/d/d0/DeviationsFromIPK.svg/330px-DeviationsFromIPK.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/d/d0/DeviationsFromIPK.svg/440px-DeviationsFromIPK.svg.png 2x" data-file-width="600" data-file-height="450" /></a><figcaption>Отклонения в масата на националните еталони K21–K40 и копията K32 и K8(41)</figcaption></figure> <p>Освен простото износване, на което са подложени контролните еталони, дори масата на грижливо съхраняваните национални еталони може да се отклони от тази на Международния еталон по различни причини, някои от които са известни, а други не. Тъй като Международният еталон и неговите копия се съхраняват във въздух, макар и под два или повече стъклени похлупака, масата им се увеличава чрез <a href="/wiki/%D0%90%D0%B4%D1%81%D0%BE%D1%80%D0%B1%D1%86%D0%B8%D1%8F" title="Адсорбция">адсорбция</a> на атмосферни замърсители по повърхността.

Преди публикувания пред 1994 година доклад на Международното бюро за мерки и теглилки за относителните промени в масата на еталоните различните стандартизационни организации използват различни техники за почистване на своите еталони. Например в Съединените щати дотогава те се потапят и изплакват първо в <a href="/wiki/%D0%91%D0%B5%D0%BD%D0%B7%D0%B5%D0%BD" title="Бензен">бензен</a>, след това в етанол и накрая се почистват със струя от двойно дестилирана вода. Почистването на еталоните отстранява между 5 и 60 µg замърсители в зависимост главно от времето от предходното почистване. Повторно почистване може да премахне още до 10 µg. Непосредствено след почистването еталоните започват отново да трупат допълнителна маса и Международното бюро разработва специален модел за нейната оценка – средно по 1,11 µg месечно за първите 3 месеца след почистването и 1 µg годишно след това. Тъй като контролните еталони не се почистват при рутинно калибриране на други еталони, за да не се износват или повреждат, моделът на Международното бюро се използва за изчисляването коригираща добавка според времето, изминало след последното почистване. </p> <div class="mw-heading mw-heading2"><h2 id="Бележки"><span id=".D0.91.D0.B5.D0.BB.D0.B5.D0.B6.D0.BA.D0.B8"></span>Бележки</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=%D0%9A%D0%B8%D0%BB%D0%BE%D0%B3%D1%80%D0%B0%D0%BC&veaction=edit&section=8" title="Редактиране на раздел: Бележки" class="mw-editsection-visualeditor"><span>редактиране</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=%D0%9A%D0%B8%D0%BB%D0%BE%D0%B3%D1%80%D0%B0%D0%BC&action=edit&section=8" title="Edit section's source code: Бележки"><span>редактиране на кода</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-references-wrap mw-references-columns"><ol class="references"> <li id="cite_note-:0-1"><span class="mw-cite-backlink">↑ <a href="#cite_ref-:0_1-0"><sup><i><b>а</b></i></sup></a> <a href="#cite_ref-:0_1-1"><sup><i><b>б</b></i></sup></a></span> <span class="reference-text"><span class="citation reference"> <a rel="nofollow" class="external text" href="https://web.archive.org/web/20181123104911/http://www.npl.co.uk/news/international-system-of-units-overhauled-in-historic-vote">www.npl.co.uk</a>, архив на <a rel="nofollow" class="external text" href="http://www.npl.co.uk/news/international-system-of-units-overhauled-in-historic-vote">оригинала</a> от 23 ноември 2018<span class="printonly">, <a rel="nofollow" class="external free" href="https://web.archive.org/web/20181123104911/http://www.npl.co.uk/news/international-system-of-units-overhauled-in-historic-vote">https://web.archive.org/web/20181123104911/http://www.npl.co.uk/news/international-system-of-units-overhauled-in-historic-vote</a></span><span class="reference-accessdate">, посетен на 16 ноември 2018</span></span><span class="Z3988" title="ctx_ver=Z39.88-2004&rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Abook&rft.genre=book&rft.btitle=www.npl.co.uk&rft_id=https%3A%2F%2Fweb.archive.org%2Fweb%2F20181123104911%2Fhttp%3A%2F%2Fwww.npl.co.uk%2Fnews%2Finternational-system-of-units-overhauled-in-historic-vote&rfr_id=info:sid/en.wikipedia.org:%D0%9A%D0%B8%D0%BB%D0%BE%D0%B3%D1%80%D0%B0%D0%BC"><span style="display: none;"> </span></span></span> </li> <li id="cite_note-faq-2"><span class="mw-cite-backlink"><a href="#cite_ref-faq_2-0">↑</a></span> <span class="reference-text"><cite class="book" style="font-style:normal"><a rel="nofollow" class="external text" href="https://web.archive.org/web/20190629185959/https://www.bipm.org/en/measurement-units/faqs.html">FAQs: Frequently Asked Questions about the revision of the SI</a> //    Архивиран от <a rel="nofollow" class="external text" href="https://www.bipm.org/en/measurement-units/faqs.html">оригинала</a> на 2019-06-29.
