EN60335,测试标准讲解,(,安全及功能测试,),目录,2,1.一般检验项目说明,Packaging,Content,Label&Marking,Cosmetic,Construction,Function&Safety,Transit.please see below for details.,包装,内容,标识,外观,结构,功能及安全,运输.以下详述.,3,1)包装:根据客人的采购协议(BA-Buying Agreement),2)内容:根据产品设计需求及客人采购协议,3)标签及标识:根据目的地相关标准及客人采购协议,4)结构:根据目的地相关标准,5)功能及安全:章节2&3详述,1.一般检验项目说明,4,6)外观:最具有主观性的检验项目,根据不同产品/表面处理方式/部位/目的地/(价格)/客人/程度等而不同,无确定统一标准.,一般而言,对所有的检验项目的区分可作为外观检验的指引,具体内容如下:,(外观检验条件:光线充足情况下,距离目标物体12“(30CM)清晰可见为判定依据),1.一般检验项目说明,5,Critical Defect(,致命缺陷),Defects which could result in hazardous or unsafe conditions for individuals using or,maintaining the product as well as defects contravening legal regulations.,用户在使用或保养过程中会导致伤害或不安全的状况,或者违反(当地的)法律法规.,1.一般检验项目说明,6,Major Defect(,严重缺陷),Functional defects reducing the usability or solidity of the product as well as obvious visual defects reducing the sales value of the product.,产品功能性缺陷影响产品的可用性或可靠性,或者明显的外观缺陷会影响产品的销售价值/客户的购买欲望.,1.一般检验项目说明,7,Minor Defect(,轻微缺陷),Defects that are unlikely to reduce the use of the product,but nevertheless may influence the sale.,不影响产品的使用,但有可能影响产品销售的状况.,1.一般检验项目说明,8,7)运输:对已包装的产品的评估,根据客人要求及自身实际情况而确定.一般依据为ISTA-International Safety Transit Association标准,其中振动(Vibration),冲击(Shock-Impact)等测试,需要专用设备在实验室进行,检验过程常用落地/摔箱来测试运输要求.(对ISTA不包括的温湿度,压力,异常操作等情况,可根据实际需要安排测试),落地测试设备可以符合ASTM-American Society of Testing Materials-D 5276-98标准要求,如果无相关设备,可用手模拟.,通常使用的标准为ISTA-1A&2A,具体标准如下:,1.一般检验项目说明,9,如何定义面,边,角-1,1)Place the packaged-product in its intended shipping position.If the shipping position can be variable,place the packaged-product so that the primary shipping label location is on the top surface,2)Does the packaged-product have only six faces(2 sides,2 ends,top and bottom)?If YES,then go to step 5.If NO,continue to next step,3)Develop a method to identify each face,edge and corner and document with a diagram,4)Go to next Block,5)Is the package a corrugated container?If YES,continue to next step.If NO,then go to step 8,6)Does the package have a manufactures joint connecting a side and an end face?If YES,continue to next step.If NO,then go to step 8,1.一般检验项目说明,10,如何定义面,边,角-2,7)Turn the packaged-product so that you are looking directly at a face with the manufactures joint on the observers right and go to step 9,8)Position one of the smallest width faces of the packaged-product directly in front of you,9)Identify faces according to the diagram below:Top as#1 face;Bottom as#3 face;Right side as#2 face;Left side as#4 face;Front as#5 face;Back as#6 face;(Edge 2-3 as manufacturings joint),10)Identify edges using the numbers of the two faces forming that edge,11)Identify corners using the numbers of the three faces that meet to form that corner,12)Go to next Block,1.一般检验项目说明,11,落地测试程序-1,1,)Determine the test method and drop height,2)Do you have a packaged-product with six faces?If YES,continue to next step,If NO,then go to step 5.,3)Test the packaged-product following the sequence in table below,a)Most fragile face-3 corner,if not known,test 2-3-5,b)Shortest edge radiating from the corner tested,c)Next longest edge radiating from the corner tested,d)Longest edge radiating from the corner tested,e)One of the smallest faces,f)Opposite small face,1.一般检验项目说明,12,落地测试程序-2,g),One of the medium faces,h)Opposite medium face,i)One of the largest faces,j)Opposite large face,4)All test is complete,mark down test procedure and result on report,5)Select a bottom face corner to replace the corner required in step 4 sequence 1,6)Identify the edges of packaged-product that meet step 4 sequence 2 4,7)Select any 6 faces to replace faces required in step 4 sequence 5 10,8)Using corner,edges,faces identified in step 6 8 to conduct the test(step,4),1.一般检验项目说明,13,ISTA-1A落地高度,1.一般检验项目说明,已包装产品重量,落地高度,大于等于,小于,自由落地,磅,公斤,磅,公斤,英寸,毫米,0,0,21,10,30,760,21,10,41,19,24,610,41,19,61,28,18,460,61,28,100,45,12,310,100,45,150,68,8,200,14,ISTA-2A落地高度,1.一般检验项目说明,已包装产品重量,落地高度,大于等于,小于,自由落地,磅,公斤,磅,公斤,英寸,毫米,0,0,21,10,38,970,21,10,41,19,32,810,41,19,61,28,26,660,61,28,100,45,20,510,100,45,150,68,12,310,15,2.UL1278测试标准(功能及安全),1)Construction-Accessibility
