Disclaimers:

This report must not be used by the customer to claim product certification, approval or endorsement by NVLAP, NIST or any agency of the federal government.

The results contained in this report pertain only to the tested sample.

This report shall not be reproduced, except in full, without written approval of the CESTL.

Items marked with a single asterisk are not covered by the NVLAP accreditation.

In the event that the recorded temperature is outside of 25 ± 1˚C, this is considered a non-standard condition.

** In the event that testing is subcontracted, test results in this report marked with the symbol **, or noted as

“Sphere” or “Integrating Sphere”, were performed by the subcontracted laboratory identified in the footer on the

first page of this report. Subcontracted testing is strictly integrating sphere based. All other tests are

performed using a Type C goniophotometer.

The integrating sphere information in the equipment list, report items marked with **, or results specifically

identified as “Sphere” or “Integrating Sphere”, are the actual equipment used, and test results produced, by the

subcontracted laboratory when subcontracting is indicated on the cover page.

Additional Comments:

The photos below are intended to show the orientation and fixturing/set-up of the units under test. These

are critical to understanding the results of the test given the sensitivity of many products and

measurement systems to orientation and set-up considerations, and also for reproducing the conditions of

the test.
