Cell Certification.

We frequently have requests for a 'Certificate of Conformity' for a particular cell or cell type.
However there is immediately the question 'Batch' or 'Individual'? the requirements for both types - depend on the cell type, market sector, etc.As invariably the parameter of interest is the pathlength of the cell, we have adopted the following conventions, to clarify this situation.

1. Certificate of Conformity.
Certificate will only specify that the cell supplied is compliant with the published specification. No individual cell measurements are provided. 2. Certificate of Cell Pathlength.

THIS CERTIFICATION IS ONLY AVAILABLE FOR CELLS
WITH PATHLENGTHS OF 0.5 mm OR LESS.

The cell will have a unique serial number, and after being identified as such, additional measurements will be performed (over and above normal Q.C.) measurements.
These measurement will then be reported on the certificate, with the calculated (or measured) pathlength for that individual cell.
As stated in the catalogue on page 2 - This Certificate of Pathlength will attract an additional charge for the cell over the listed price.

IN BOTH CASES, EITHER CERTIFICATE MUST BE REQUESTED AT THE TIME OF ORDERING.
