ASTM A475 Seng Coated Steel Wire Strand
1 Cakupan
1.1 Standar iki ditrapake kanggo limang gelar untaian baja galvanis sing digunakake kanggo lanyard, sling, kabel ereksi lan tujuan sing padha sing kasusun saka kabel baja bunder ing papat klompok bobot galvanis.
1.2 Lima tingkat kasebut yaiku:
1.2.1 Tingkat umum;
1.2.2 Tingkat normal
1.2.3 Tingkat hearth mbukak;
1.2.4 Tingkat intensitas dhuwur;
1.2.5 tingkat kekuatan Ultra-dhuwur.
1.2.6 Kanggo beban putus minimal saben kelas untaian baja, deleng Artikel 8.
1.3 Kelompok bobot 4 lapisan seng yaiku: Tipe 1 lan Kelas A, Kelas B lan Kelas C. Waca Artikel 12 kanggo bobot minimal lapisan seng.
14 Nilai sing dituduhake ing sistem unit jam-pound minangka nilai standar, lan nilai ing kurung mung kanggo referensi.
2 standar referensi

3 istilah
3.1 Dhéfinisi tembung sing tepat sing digunakake ing standar iki yaiku A902
3.2 Katrangan istilah khusus ing standar iki:
3.2.1 Kawat terdampar-cara ekspresi kawat terdampar baja rampung yaiku: diameter nominal kawat terdampar, jumlah kawat baja ing kawat terdampar, beban putus minimal kawat terdampar (pirsani 8), lan lapisan jinis utawa klompok (ndeleng 12).
4 Isi pesenan 00
4.1 Pesenan sing diwenehake miturut standar iki kalebu:
4.1.1 Jumlah kabel bengkong, diukur kanthi sikil;
4.1.2 Diameter nominal kawat terdampar, jumlah kawat baja, kelas lan beban putus minimal kawat terdampar (Pasal 8 lan Tabel 1);
4.1.3 Bobot lapisan seng (jinis lan klompok) (Pasal 12 lan Tabel 4);
4.1.4 Dawane kabel stranded coil utawa spool (Pasal 19).
5 Bahan lan manufaktur
5.1 Logam dasar kudu baja sing dilebur nganggo tungku perapian sing mbukak, konverter top-blown oksigen utawa tungku listrik. Kualitas lan kemurnian baja kudu bisa mesthekake yen nalika kawat baja ditarik menyang ukuran sing ditemtokake lan galvanis, kualitas untaian lan monofilamen sing wis rampung kudu seragam lan nduweni kinerja lan karakteristik sing ditemtokake ing standar iki.
5.2 Ingot seng digunakake kanggo galvanizing kudu ketemu sembarang tingkat kasebut ing standar B6.
6 wuwus
6.1 Yen ora ditemtokake, kabel bengkong bakal ditinggalake bengkong. Puteran kiwa ditetepake minangka puteran ing arah counterclockwise relatif marang pengamat. Kabeh kabel baja kudu bengkong kanthi ketegangan seragam. Puteran kudu cukup nyenyet kanggo mesthekake yen diameteripun ora bakal suda sacara signifikan nalika tension 10% saka beban break minimal ditrapake.
6.2 1 × 3 kabel terdampar kudu dumadi saka 3 kabel baja bengkong concentrically, lan dawa lay seragam ora kurang saka 14 kaping diameteripun nominal saka kabel terdampar lan ora luwih saka 20 kaping.
6.3 1 × 7 kabel terdampar kudu dumadi saka 6 kabel baja concentrically bengkong watara kabel tengah, lan duwe dawa lay seragam ora luwih saka 16 kaping diameteripun nominal saka kabel terdampar.
6.4 1 × 19 kabel terdampar kudu kalebu 6 kabel baja njero lan 12 kabel baja njaba concentrically bengkong watara kabel baja tengah. 6 kabel baja kudu bengkong kanthi tangan tengen lan kudu diameter nominal ora luwih gedhe tinimbang 7 kabel baja. Kaping seragam lay dawa. Dhiameter nominal saka 7 inti kawat baja kudu 3 kaping diameteripun nominal saka kawat baja. 12 kabel ing lapisan njaba sing kiwa-bengkong lan kudu concentrically bengkong watara 7 intine kabel, lan dawa lay seragam ora luwih saka 16 kaping diameteripun nominal saka kabel terdampar.The 6,51 × 37 untaian bakal dumadi saka 6 kabel baja batin, 12 kabel baja penengah lan 18 kabel baja njaba concentrically bengkong watara kabel baja tengah. 6 kabel baja sing bengkong kiwa lan ora luwih saka 7 kabel. A seragam lay dawa 16 kaping diameteripun nominal inti kawat baja. Dhiameter nominal saka 7 inti kawat baja kudu 3 kaping diameteripun nominal saka kawat baja. 12 kabel baja tengah-lapisan bengkong tangan tengen lan concentrically bengkong watara 7 intine kabel baja, lan duwe dawa lay seragam ora luwih saka 16 kaping diameteripun nominal saka 19 intine kabel baja. Dhiameter nominal saka 19 inti kawat baja kudu 5 saka diameter nominal kawat baja. 18 kabel baja njaba sing kiwa-bengkong lan concentrically bengkong watara 19 intine kawat baja, lan duwe dawa lay seragam ora luwih saka 16 kaping diameteripun nominal saka kabel terdampar.
6.6 Kabeh kabel baja ing kabel terdampar kudu alamiah ing posisi sing bener ing untaian baja rampung. Nalika kabel terdampar dipotong, kabel ing mburi rusak kudu katahan ing panggonan utawa kabel bisa gampang ngreset dening tangan kanggo tetep ing panggonan. Ing situ. Bisa digayuh kanthi macem-macem cara utawa proses, kayata pre-deformasi, post-deformasi utawa mbentuk lan ndandani.
