RoHS&REACH report of stainless steel materials
- Sep 17, 2017 -

Our stainless steel watches case and band are from the environmental raw-materials. They are approved to be the eco-friendly and not harmful to human beings. The stainless steel materials are passed by RoHS and REACH testing by SGS. The below pictures are the conclusions of testing for 304/316L stainless steel materials. The test reports are the latest in 2017.


As to stainless steel watches, there are 2types of stainless steel raw-materials chosen by watch dealers. They 304 stainless steel and 316L stainless steel.


Currently, most of minimalist watches are made of stainless steel case and our products are not harm to end-users. 


What can be stainless steel applied to?

  1. types: women watches, men watches, unisex watch, gift watches

  2. functions: analog watches, chronograph watches, automatic mechanical watches, diving watches

SN1. CAN16-258318.001 Silver-grey metal board.

 

Remarks :.

 

(1) 1 mg/kg = 1 ppm = 0.0001%.

 

(2) MDL = Method Detection Limit.

 

(3) ND = Not Detected ( < MDL ).

 

(4) "-" = Not Regulated.

 

 

RoHS Directive (EU) 2015/863 amending Annex II to Directive 2011/65/EU.

 

Test Method :. (1)With reference to IEC 62321-5:2013, determination of Cadmium by ICP-OES. (2)With reference to IEC 62321-5:2013, determination of Lead by ICP-OES.

 

(3)With reference to IEC 62321-4:2013, determination of Mercury by ICP-OES.

 

(4)With reference to IEC 62321-7-1:2015 , determination of Hexavalent Chromium by Colorimetric

Notes :.

 

(1) The maximum permissible limit is quoted from RoHS Directive (EU) 2015/863.

 

(2) ▼= a. The sample is positive for CrVI if the CrVI concentration is greater than 0.13 μg/cm2. The

 

sample coating is considered to contain CrVI

 

b. The sample is negative for CrVI if CrVI is ND (concentration less than 0.10 μg/cm2). The coating is considered a non-CrVI based coating

 

c. The result between 0.10 μg/cm2 and 0.13 μg/cm2 is considered to be inconclusive - unavoidable coating variations may influence the determination

 

Information on storage conditions and production date of the tested sample is unavailable and thus Cr(VI) results represent status of the sample at the time of testing.

 

IEC 62321 series is equivalent to EN 62321 series http://www.cenelec.eu/dyn/www/f? p=104:30:1742232870351101::::FSP_ORG_ID, FSP_LANG_ID:1258637,25.
