O le ASTM A871 faʻamatalaga o le faʻamatalaga masani mo ipu uʻamea faʻapipiʻi maualalo-maualalo faʻatasi ma le faʻafefe o le ea o loʻo faʻaaogaina i fausaga tubular ma pou. Vasega 60 ma le 65 o lo'o avanoa i tulaga fa'asolo, masani, pe tineia ma fa'afefeteina e pei ona mana'omia e ausia ai mea tau masini fa'apitoa.

O faʻamatalaga:
Mafiafia: 3mm--150mm
Lautele: 30mm--4000mm
Umi: 1000mm--12000mm
Tulaga masani: ASTM EN10025 JIS GB

A871 Vasega 65 e mafai ona tuʻuina atu e pei ona taʻavale, faʻasaʻo pe tineia ma faʻafefe.
