    B Madaraja yaliyoonyeshwa kwenye jedwali hili yenye herufi B, kama vile 50B40, yanaweza kutarajiwa kuwa na udhibiti wa boroni wa 0.0005%. AMadaraja yaliyoonyeshwa kwenye jedwali hili yenye kiambishi awali cha herufi E kwa ujumla yanatengenezwa kwa mchakato wa tanuru-msingi-umeme. Nyingine zote kwa kawaida hutengenezwa kwa mchakato wa msingi-wazi-wazi lakini zinaweza kutengenezwa na mchakato wa msingi wa tanuru ya umeme na marekebisho katika fosforasi na sulfuri.

    Uvumilivu wa unene wa ukuta hauwezi kutumika kwa kuta za inchi 0.199 (milimita 5.05) na chini; wasiliana na mtengenezaji kwa uvumilivu wa ukuta kwenye saizi kama hizo za bomba.
    kipimo muhimu zaidi, basi neli inayofanya kazi kwa baridi inapaswa kubainishwa kwa kipenyo cha ndani na unene wa ukuta au kipenyo cha nje na kipenyo cha ndani.
    Mirija ya Mitambo Iliyogeuka Mbaya—Kubadilika kwa kipenyo cha nje na unene wa ukuta hautazidi uvumilivu ulio kwenye Jedwali. Jedwali inashughulikia uvumilivu kama inavyotumika kwa kipenyo cha nje na unene wa ukuta na inatumika kwa saizi maalum.
    Mirija ya Mitambo ya Ardhi—Utofauti wa kipenyo cha nje hautazidi uvumilivu ulio kwenye Jedwali. Bidhaa hii kawaida hutolewa kutoka kwa bomba la kazi baridi.
    Urefu—Miriba ya kimakaniki hutolewa kwa urefu wa kinu, futi 5 (m 1.5) na zaidi. Urefu dhahiri wa kukata hutolewa wakati umebainishwa na mnunuzi. Uvumilivu wa urefu unaonyeshwa kwenye Jedwali.
    Unyoofu—Ustahimilivu wa unyoofu kwa mirija ya duara isiyo na mshono hautazidi kiasi kilichoonyeshwa kwenye Jedwali.

     

    Mahitaji ya Mtihani

    1.Mtihani wa Ugumu
    Wakati mipaka ya ugumu inahitajika, mtengenezaji atashauriwa. Ugumu wa kawaida umeorodheshwa kwenye Jedwali. Inapobainishwa, mtihani wa ugumu utafanywa kwenye 1% ya mirija.

    2.Vipimo vya Mvutano
    Wakati mali ya mvutano inahitajika, mtengenezaji atashauriwa. Tabia za kawaida za mvutano kwa baadhi ya alama za kawaida na hali ya joto zimeorodheshwa kwenye jedwali.

    3.Vipimo Visivyoharibu
    Aina mbalimbali za majaribio yasiyo ya uharibifu ya ultrasonic au sumakuumeme zinapatikana. Jaribio litakalotumika na mipaka ya ukaguzi itawekwa na makubaliano ya mtengenezaji na mnunuzi.

    Mtihani wa 4.Flaring
    Wakati kuna mahitaji maalum ya usafi wa chuma, mbinu za mtihani na mipaka ya kukubalika itaanzishwa na makubaliano ya mtengenezaji na mnunuzi.
