邵氏A型硬度计国内外标准差异解析

Analysis of Differences in Domestic and Foreign Standards for Shore A Hardness Testers

分析国内外用于橡胶材料的邵氏A型硬度计的使用、校准和检定标准,并对各标准的技术参数,包括压针顶端平面直径、压足直径、压足内孔直径、压针最大伸出量和施加到压针上的弹簧力允差等进行了比较,这对邵氏A型硬度计生产和使用企业、校准和检定机构有借鉴作用。

The use,calibration and verification standards of Shore A hardness testers used for rubber materials at domestic and foreign were analyzed,and the technical parameters of each standard,including the diameter of the cone frustum top,the diameter of the pressure foot,the diameter of pressure foot hole,the maximum extension of indentor and the allowable spring force applied to indentor were compared.This provided reference for Shore A hardness tester production and use enterprises,and the calibration and verification institutions.
