GENERAL GUIDE TO
Shelf Life & Warranty
Met-L-Chek Company manufactures a complete line of nondestructive testing penetrant and magnetic particle materials
All Met-L-Chek Company products are designed to yield maximum value through quality, cost, and usability. Met-L-Chek
Company products are sold under the Met-L-Chek
and Pen-Chek trademarks. Met-L-Chek Company products are manu-factured under license in The Netherlands by NDT Europa.
Met-L-Chek Company denes shelf life as the period of storage time, in closed containers, at ambient conditions
(50-100F/10-37.7C), during which an inspection material will retain its functionality. The stated shelf life of most Met-
L-Chek Company inspection penetrant materials is ve (5) years from date of batch approval. The shelf life of a particlular
material is stated on the batch certication. Older materials performance may be veried through the Met-L-Chek Company
Pen-Chek
recertication program.
Inspection materials packed in aerosol cans maintain their functionality providing sufcient propellant remains in the can
to expel the material. Aerosol cans whos propellant has dissipated (escaped) to a level where the material can no longer
be expelled effectively should be rendered unserviceable and discarded within the parameters of local, state and federa
guidelines. See general guide to aerosol cans.
Inspection materials packed in aerosol cans, exceeding the printed shelf life interval, but maintaining sufcient propellant
to effectively expel the material, will maintain their functionality/usability and may be used until the materials become de
pleted or the propellant dissipates (escapes) to a level where the material can no longer be expelled effectively.
Met-L-Chek Company has a three (3) year warranty period, from date of batch approval, on all its products including aero
sols. The warranty covers the replacement of any material found to not perform as intended, provided the material has been
stored in a closed container at ambient conditions. Met-L-Chek Companys liability is limited to the invoice price of the
material at time of purchase.
In-use materials are not covered by the storage shelf life and warranty. Continued usability of materials may be veriedthrough the Met-L-Chek Company Pen-Chek
or Mag-Chekrecertication program. The Pen-Chek
program con
forms to the requirements of AMS-2644E and ASTM E-1417. The Mag-Chek program conforms to the requirements
ofASTM E-1444.
All containers of Met-L-Chek Company products contain a batch number on the label or on the bottom of the can, in the
case of aerosols. The batch number consists of 4 numbers a letter and two numbers. The rst numbers are the batch, the let
ter is for the month (January = A), and the last numbers are the year. This number is required for identifying a material when
requesting lost certication papers. The date of batch approval is printed on all bulk material labels as well as the stated
storage shelf life period. All Met-L-Chek Company penetrant materials are tested, prior to shipment per the requirements of
AMS-2644E and other OEM requirements, and are certied to their conformance to the requirements.
Met-L-Chek Company has been a QPL qualied penetrant manufacturer since 1952.
