\r球壓測試儀基本簡介：<\/strong><\/span><\/span>\r<\/p>\r

\r1<\/span>、根據(jù)<\/span>GB4706.1-2005<\/span>、<\/span>GB2099.1-2008<\/span>、<\/span>GB/T5159.21-2006<\/span>、<\/span>IEC60695-10-2<\/span>：<\/span>2003<\/span><\/span><\/span>等標準制作而成。
\r2、球壓試驗是將規(guī)定鋼球<\/span>(R2.5mm)<\/span>和總試驗力<\/span>20N±0.2N<\/span>的球壓試驗儀，壓在呈水準狀態(tài)且置于加熱箱內的試品表面上，在試品規(guī)定的溫度下經(jīng)<\/span>60min+2min/0min<\/span>后，將試品快速<\/span>(<10s)<\/span>浸入<\/span>20<\/span>℃<\/span>±5<\/span>℃<\/span>水中冷卻<\/span>6min±2min<\/span>，從水中取出<\/span>3min<\/span>內測量試品表面壓痕直徑，視壓痕直徑是否超過<\/span>2mm<\/span><\/span><\/span>來評定試品在該規(guī)定的溫度下的耐熱變形能力。
