TESTCOO/2021-10-25

一、电器分类

按其他类别

-电热器具:装有电热元件而不带有电动机的器具。

-电动器具:装有电动机而不带有电热元件的器具。

-联合型器具:装有电动机和电热元件的器具


二、电热器具

-电热类有电热水壶/电热咖啡壶/电熨斗/三明治炉/多士炉/取暖器/烤箱等;

-电动类有吸尘器/打蛋器/搅拌器/电风扇/榨汁机等;

-联合型器具有电吹风/加湿器等;

-大型家电有空调/冰箱/洗衣机/抽油烟机等。


电热水壶根据不同底座有下面几种:

1. 直插式

2. 360旋转

3. 电源线插拔式.(带尾插)


电热水壶:

外观注意事项:如果是塑料件,那需要注意壶身和底座的颜色是否一致.有可能材料不一致而导致有色差,那需要查看客人订单,参考样品,彩盒产品照片.

塑料件注意飞边,缩水,气纹,划痕等外观不良.各个装配部位缝隙应该均匀,间隙不要大于0.8mm.不要有松动/变形等不良现象.

金属件,表面应该注意划痕,锈斑,电镀不良及指纹印等不良情况,外观应该符合客人订单及样品. (例如不锈钢镜面及哑光效果)

最好大货和彩盒照片放一起拍张照片.


三、基本测试

1.Transportation drop test

2.Product Size /power cord length / Weight Measurement (量尺寸的时候尺子拉直,如果卷尺头子有松动,可以从10cm位置开始测量)

3.Bar code scan check

二维码(app下载个二维码扫描软件,可以扫描出链接,如果不能连上,拍链接照片备注即可)

4.Assembly/installation check

5.Coating Adhesive Tape Test

6.Stability test(加Max刻度的水,并且电源线要放在最不利的方向)

7.High voltage test

8.Power on check (注意冷却5分钟再加入冷水)

(留意盖子是否松开或者打不开)

9.Earth continually test if applicable/10.Power consumption check

11.Power cord strain relief test

(如果没有拉力器,可以吊相应的重量,这个测试最好不要备注没有仪器)

12.Internal workmanship and critical component check

13.Rubbing test for rating label and adhesive Test for printing, marking and logo

基本测试:如果产品是360度旋转的.

14.Jug body 360 degree rotation check

Poured purified water into Min. level, input rated voltage and switch on, then slowly turned jug body along base for two circle (clockwise and anti-clockwise), check if intermittent function between jug and base.

(其他要求壶身和底座之间垫0.5mm厚的垫圈不能有接触不良的问题发现)

15.Boiling hot water temperature check

Poured purified water into Max level, then input rated voltage and switch on, measured boiling water temperature (centre position) after steam switched off and record actual data into report.

the water should not spray out of kettle, and the lid should be on the housing properly.

(正常烧水应该水不会溅出,如果有问题可以根据溢出或飞溅出的量来备注,拍照或视频来正面)(水温一般要大于98C,时间客人有要求就记录,一般温度到98C后30秒以内温控会跳,当然根据结构不同,如果蒸汽开关在手柄下部就会慢一点)

16.capacity check

The capacity should be complied with requirement (claims)

(一般正负5%)

17.Timing accuracy check (for with timing function item) Timer should be set as per instruction manual and the timer is set at max. time, and then to operate it, the actual time should be measured, if no client requirement, the tolerance requirement is: electronics type +/-1minutes, mechanical type +/-10%

18.Dry boiling check

Apply a lower voltage( about 70% of rated voltage ) with no water in the kettle, then check if thermal control switch operates as intended. no safety issue occurs.

(看下是否发黄变色,塑料是否变形,温控起跳时间是否太慢<60S)

19.Handle strength check

The fixing system of handle shall bear a bending stress force of 100N(applied on (each) handle) for 1 minute.

Or The assemblies of handle must support a weight equal to 2 times the weight of the water capacity of the unit plus the weight of any cover intended for use with the unit for 1 minute.

no any failure of the securing system after testing, i.e. rivets, welds, etc.

20.Smell check Pour tap water into Min. level and input rated voltage and check if

product emitted bad smell from hot water/body during brewing

21.Full function check (including the function which only can be checked after fully assembling.)

All of intended functions what specified in instruction manual should be operated and checked, and all should work properly as intended.

such as installation/assembly, adjusting, switch/knob action check, setting, other actual using function etc.

all of function should be complied with spec.


四、基本结构

产品基本都有logo-都需要做丝印粘贴测试

两边都有刻度_基本都有容量测试

内部检查-核对CDF

指示灯注意移位. 1m内观察

干烧测试_可以调低电压来防止发热管变色_发热盘底部温控

烧水测试_蒸汽温控基本结构:

正规一点的有三级保护,有些老的插入式的应该没有.3级保护:

1.蒸汽温控(这个指手柄开关位置的那个温控或老的一体温控)

正规一点的有三级保护,有些老的插入式的应该没有3级保护:

2.如果蒸汽温控失效那壶里的水会一直烧下去,直到烧干,然后发热盘底部温控会起作用.

3.如果这个温控也失效,随着温度升高,温控器内一个塑料推杆将会融化,会使水壶断电. (这个测试看工厂,如果安全有保证工厂有多余的产品大家可以试着做一下)

铭牌需要壶体和底座都要有的。
