5、響的缺陷對使用無明顯影響的缺陷4.判定步驟及說明4.1判定步驟4.1.1 目測判定4.1.2 戴手套觸摸制件表面，手感判定。4.1.3磨制件外表面后目測判定。4.1.3.1用油石(一般規(guī)格20X20X200)磨制件外表面。4.1.3.2用相應(yīng)的小油石(如10X10X100)磨圓角和不易磨到的部位。4.1.3.3按制件的表面情況(如粗糙度、有無鍍鋅屬等)迭擇油石粒度，一骰迭400至500號粒度。4.1.3.4磨件原則上應(yīng)按整車的長度方向進行，特殊部位也可橫向或斜向磨件。圖1至圖6繪出了有代表性的幾種外表件的不同部位的磨件方向和使用油石的規(guī)格，供參考。4.2.1檢查制件的每一區(qū)域，已判定的缺陷要用

6、蠟筆圈出，井標明缺陷和匡域代號如Bl(代表一區(qū)的B類缺陷其余類推)、B2、B3等。4.2.2油箱蓋口或門把手洼赴上下部表面，同類缺陷在判定吋歸為一個缺陷。4.2.3單個的凸包不分區(qū)域，歸為一介缺陷并按一區(qū)評宙。5缺陷區(qū)域 本標準按缺陷被人反響的可能程度及其對整車外觀質(zhì)量的影響程度，將整車各部面劃分力三個域即:一區(qū)、二區(qū)、三匡。(見圖7)5.1.1一區(qū) 能直接被人發(fā)現(xiàn)缺陷的整車內(nèi)外表面稱為一區(qū)。該區(qū)的缺陷嚴重影響整車的外觀質(zhì)量。5,1.2二區(qū) 不能直接被人發(fā)現(xiàn)缺陷或須稍加注意才能發(fā)現(xiàn)缺陷的整車內(nèi)外表面稱為二區(qū)，該區(qū)的缺陷對整車外觀質(zhì)量有較大影響。5.1.3三區(qū) 所有被其它零件覆蓋的整車內(nèi)外表面，

7、以及在車輛使用過程中很少或短時間內(nèi)不易看到的整車內(nèi)外表面稱為三區(qū)該區(qū)的缺陷對整車外觀質(zhì)量影響較小。5.2 缺陷區(qū)域劃分示例 圖7至圖15是車型的區(qū)域劃分，可供評定吋參照。6表面奧迪特等級6.l 評定方法6.1.1評是制件各部的缺陷，并標出缺陷和匡域代號(填入表5)6.1.2評出各缺陷部的缺泄點數(shù)，并累加得到該制件的缺陷點數(shù)(填入表5)。6.1.3根據(jù)點缺陷點數(shù)，在奧迪特等級對照表(表4)中按制件名稱查出對應(yīng)的表面奧迪特等級分值。6.2表面奧迪特等級對照表見表4所示表面奧迪特對照表 (表4)制件名稱： 車門外板等級缺陷點數(shù)等級缺陷點數(shù)等級缺陷點數(shù)5.01061.71153.93.3257.627
