- ASTM tus qauv lej daim ntawv
Standard code + tsab ntawv cais code + standard serial tooj + xyoo ntawm kev loj hlob + standard English npe.
Nqe lus piav qhia:
1. tus qauv serial tooj nrog tsab ntawv M rau metric unit standard, tsis muaj tsab ntawv M rau imperial unit standard.
2. Lub xyoo nyob rau hauv kab lus tom qab lub xyoo ntawm formulation yog lub xyoo thaum tus qauv revalidated.
3. abc.... Qhia txog kev kho dua tshiab.
4. Tsab ntawv cais code yog:
A -- Ferrous hlau
B -- Cov hlau uas tsis yog ferrous (tooj liab, aluminium, hmoov metallurgical cov ntaub ntawv, xov hlau, thiab lwm yam)
C - cement, ceramics, pob zeb thiab masonry cov ntaub ntawv
D - ntau yam khoom siv (cov khoom siv roj av, roj av, cov yas tsis muaj zog, thiab lwm yam)
E - Lwm yam (tshuaj ntsuam xyuas ntawm cov hlau, kev ntsuam xyuas refractory, kev ntsuam xyuas tsis muaj kev puas tsuaj, kev txheeb cais, thiab lwm yam)
F - Cov khoom siv tshwj xeeb (cov khoom siv hluav taws xob, cov khoom tsis zoo, cov khoom siv phais, thiab lwm yam)
G - Corrosion, deterioration thiab degradation ntawm cov ntaub ntawv
