    General.
For an object to pass the test, its 'perfection grade' shall be higher than 90%. Hence the amount of acceptable imperfections shall not be more than 9 percentage points, also called imperfection or penalty points.

Acceptable imperfections are often due to normal wear and tear, unintentional damage or misuse. 

For perfection grades to be higher than 90% is a rather demanding standard. The 'vetnorm working party' would like to stress that objects with perfection grades less than 90% could still be of great interest, especially when restorations, if any, are carefully executed.

It is stressed that establishing an object's imperfection is the sole responsibility of the test observers*, it shall be done with great care and shall be endorsed by qualified experts. In case of a possible dispute, it is suggested to appoint an arbiter expert beforehand.

* appointed by the party (parties) involved.

    About vetting criteria  level
The criteria database, as applied to perform a vetting test, is maintained by a working party of art historians and horological experts of which several have a long standing experience as vetting committee members at prestigious Art & Antiques fairs. To some extent, the database could be considered as a summary of accumulated vetting decissions. Due to ongoing re-evaluation, the current criteria are not necessarily the same as those used in the past. The working party will gladly consider any serious contributions from users and fellow experts.

The criteria are to be considered as guidelines only, and do not have any official or legal status. However, parties could mutually agree to apply a vetting test as part of a deal.
 
The weighting of an imperfection is subject to two variables, i.e. Level and Category. Hence the vetting results for two different objects, having similar imperfections, may vary substantially due to different level and or category allocation.

Important notice:

This project is about weighing imperfections not establishing imperfections.
 


    Level  (exhibition grade)
Level has to do with the purpose of a vetting test and weighs the status (degree of acceptability) of an object category when applied to a certain level.

Two levels are currently selectable:
 
- Exhibition grade II or Certification. (strict)
- Exhibition grade I. (strict, some categories banned)

If, for instance, the vetting-test applies to a 'local Antiques show' (grade II) the vetting will be less strict (more lenient) than when it applies to a prestigious International 'Fine Art & Antiques Fair' (grade I).

Level correction points

The degree of 'acceptability' is expressed by 'level' correction points, (exhibition grade points). These points are to be added to the total of the imperfection penalty points.

* Very early or rare objects (gothic, renaissance) could be treated with more leniency. (negative grade points are to reduce the total of the penalty points)
* A late 19th century 'Comtoise clock' may not qualify for exhibition at a prestigious International 'Fine Art & Antiques Fair'. (positive grade points or, if to be banned, an # )
 

    Category category
Weighing similar imperfections may vary with the object-category to which it applies. 

For instance:
 
- If the (detent) escapement of a fine and rare 18th century marine chronometer is converted to (replaced by) a platform anchor escapement, it has a much greater (fatal) impact on the clock's authenticity than a similar conversion applying to a late 19th century, mass produced, French mantel clock. 
- If restoration or reconstruction of a leg applies to a 'one' leg table, it has a much greater impact on the table's authenticity than when it applies to an 'eight' legs table.
