An object does not pass the test if the sum of its  penalty points becomes more than 9 (>9)
 
How to get the 'penalty points' for an object's imperfections:
 
1) Find and click  an imperfection issue number in the list.

Ornaments p. piece
27 side frets (2x)
29 Cresting missing
   
Going Train
51 escapement reconverted
52 escapement converted
53 weights NA

) The results (expressed by penalty points) show how an imperfection applies in general or to a selectable object category. Clarifying legends are at the end of the results list

3) If result cells
are empty, apply 'general'.
Individual penalty points are only shown if an object category deviates from general.

4) Repeat step 1) for all other imperfections of an object (if any) to obtain the sum of its penalty points.

5) If the sum of all imperfection penalties becomes more than 9 (>9) an object renders 'unacceptable'.

Important:
 This project is about weighing imperfections, not establishing imperfections.

Disclaimer:
 
These vetting test pages aims to facilitate objective and consistent vetting procedures and criteria. However, click   here   to view the terms of use.


It is stressed that establishing an object 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 on beforehand.
 

    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 extend, 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 decent 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 weighing 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.

Establishing object imperfections is the sole responsibility of the test observers*.  It shall be done with great care and preferably endorsed by qualified experts. In case of a possible dispute, it is suggested to appoint an arbiter on beforehand.

* appointed by the party (parties) involved.
 


    Level  (exhibition grade)
Level deals 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 sum of the imperfection penalty points.

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

    Category category
Weighing of 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.
