Summary of compliance with National Differences (List of countries addressed):—

Use of uncertainty of measurement for decisions on conformity (decision rule) :No decision rule is specified by the IEC standard, when comparing the measurement result with theapplicable limit according to the specification in that standard. The decisions on conformity are madewithout applying the measurement uncertainty (“simple acceptance” decision rule, previously known as“accuracy method”).
Other:… (to be specified, for example when required by the standard or client, or if national
accreditation requirements apply)
Information on uncertainty of measurement:
The uncertainties of measurement are calculated by the laboratory based on application of criteria given
by OD-5014 for test equipment and application of test methods, decision sheets and operational
procedures of IECEE.
IEC Guide 115 provides guidance on the application of measurement uncertainty principles and applying
the decision rule when reporting test results within IECEE scheme, noting that the reporting of themeasurement uncertainty for measurements is not necessary unless required by the test standard or
customer.
Calculations leading to the reported values are on file with the NCB and testing laboratory that conducted
the testing.

Measured accessible laser radiation and comparison with AEL:
1. TEST CONDITIONS(1) General requirement
Temperature:
Relative humidity:

20 – 25 oC
Max. 75 %(2) Normal operation
The Laser is simulating normal operation to emit intentional optical power.
(3) Fault condition: According to client’s requirement, fault condition was not considered.
2. MEASUREMENT METHOD(1) Measurement of Peak wavelength
The peak wavelength of Laser is measured under normal operation(2) Measuring distanceFor condition 1: r = 2000 mm.
For condition 3: r = 100 mm.
For condition Skin Thermal hazard: r = 0 mm
(3) Measurement of radiant power (used optical power meter)
The radiant power emitted from Laser of the product is measured under normal operation.
In case of condition 1, the Laser radiation is collected through a circular aperture stop having a diameter 50
mm and its location is 2000 mm away from the closet point of human access, consists of a lens with 150 mm
focal length. See below picture.

In case of condition 3, same as condition 1 except the Laser radiation is collected through a circular aperture
stop having a diameter 7 mm and its location is 100 mm away from the apparent source, and focal length ofthe lens is 35 mm.
In case of condition Skin Thermal Hazard, Laser radiation is collected through a circular aperture stop having
a diameter 3,5 mm and its location is 0 mm away from the apparent source.
The measurement is performed at a position to detect a maximum radiation emitted from the apparent
source.
After review, test result under condition 3 is stricter compared with condition 1.
