Since March 1, 2013, the EU's old version of the nickel release standard, EN 1811:1998+A1:2008, has been replaced by the new standard EN 1811:2011.
Instrument definition:
Nickel release tester, also known as rotary wear tester, is a kind of special coating used to polish the surface of metal products. It can be used as an auxiliary instrument for 2 years.
Instrument use:
The primary use of this instrument is to assist in the detection of the amount of nickel released in the EU's latest nickel release standard.
Test method:
Wear simulation of metal products in contact with the human cortex of two years, the artificial sweat under certain conditions for 7 days, with the analysis of the content in the solution of nickel atomic absorption spectrometry quantitative limit of 0.5 mg / cm2 / week.
Applicable standard:
EN12472:2005, EN, 1811:2011, GB/T28485-2012, ISO24348-2007.
Testing range: all accessories, glasses, watches and other metal products......
Instrument advantage:
First: touch screen display, simple operation, clear display, greatly facilitate the day-to-day operation of the user!
Second:
1: automatic program control, can turn at a certain time;
2: when the test is finished, the instrument will stop automatically.
Third:
The clear LED display shows the operation and remaining time, allowing the user to better distribute the work.
Fourth: safety design
1: instrument with protective door and transparent observation window, with power supply and power failure protection design, to ensure the safe use.
2: equipped with the "pause" button, so that the user can in any case temporarily stop the instrument operation.
For the EN12472:2005 determination of nickel release coating covering material of nickel release tester in simulation wear and corrosion test method standard and ISO 12870:2004 ophthalmic optics - spectacle frame - Requirements and test methods for the design specifications meet the requirements of the two standards.
