Mechanical Properties

Cov khoom siv tshuab ntawm AS 1163 tuaj yeem ntsuas tau siv peb qhov kev xeem: Tensile test, Impact test thiab Cold Flattening test.

Ua ntej kev ntsuas tensile lossis cuam tshuam, cov ntawv xeem yuav tsum muaj hnub nyoog los ntawm cua sov mus rau qhov kub ntawm 150℃thiab 200℃tsis pub tsawg tshaj 15 min.

Tensile Requirement

Kev ntsuas tensile ntsuas lub zog tawm los, lub zog tensile thiab elongation ntawm AS 1163 thiab kev xeem yuav tsum ua raws li cov cai ntawm AS 1391.
