This standard has been approved for use by agencies of the Department of Defense. In the case of orders in inch-pound units, the measured value shall be converted to coating grade units by the use of Table 2. If the lot is found to be nonconforming by the new sample, the galvanizer has the right to sort the lot for conforming articles by individual test, to re-galvanize nonconforming articles, or to renovate the nonconforming articles in accordance with 6.
Surfaces that remain uncoated after galvanizing shall be renovated in accordance with the methods in Practice A unless directed by the purchaser to leave the uncoated areas untreated for astk renovation by the purchaser.

These designations often apply to specific products, for example A is applicable to cold-heading quality carbon steel wire for tapping or sheet metal screws. Visual inspection of the coating shall be made for compliance with the requirements. Enter a phrase to search for: NOTE 5—Inaccessible surface areas are those which cannot be reached for appropriate surface preparation and application of repair materials as described in Practice A Practice A provides guidance on steel selection and discusses the effects of various elements in steel compositions for example, siliconthat in?
In the case of orders in SI units, such shall be stated to the galvanizer when the order is placed. Inspection, Rejection, and Retest 9. These tests shall not be required unless strong evidence of embrittlement is present.
Introduction to Total Materia Integrator 7 th March It is the responsibility of the purchaser to heat treat or otherwise allow for the possibility of such embrittling phenomena. The other values are based on conversions using the following formulas: In such case, the now-smaller lot shall be treated as a new lot for purposes of inspection and acceptance.
To get started, click on the standard list button in the menu bar. The weight of coating per unit area thus determined is converted to equivalent coating thickness values in accordance with Table 2 rounding up or down as appropriate. The elements can be added to the galvanizing bath as part of a pre-alloyed zinc feed, or they can be added to the bath by the galvanizer using a master feed alloy.
