Sal- Are you asking which galvanizing standard you should be using? The type of production lot process will determine which column should be referenced for the sample size of each inspection criteria, as summarized in the table below, or per the F Sampling Plan Flow Chart. When requested by the purchaser, the average galvanizing temperature that the fasteners will be subjected to shall be furnished.

This abstract is a brief summary of the referenced standard. Suppliers shall furnish certified test results from which the shipping f2239 originated. If the customer specifies, the galvanizer will be required to provide the average galvanizing temperature the fasteners will be exposed to.
