In such case, the now-smaller lot shall be treated as a new lot for purposes of inspection and acceptance.

Z386 magnetic thickness measurements, specimen excludes any area of the surface which is subject to processes such as? The thickness of coating thus obtained is the test article coating thickness, or in the case of a specimen removed from a test article, is the specimen average coating thickness. DataPLUS, a new module providing corrosion data, material joining information, material dimensions and tolerances and coatings information helps drive even more accurate material selections!

Each system shall be used independently of the other without combining values in any way.

This shall be achieved by an in-plant inspection program designed to maintain the coating thickness,? The galvanizing of separate reinforcing steel bars shall be in accordance with Speci?

Terminology A contains other terms and de? However, by agreement the purchaser is not prohibited from making tests which govern the acceptance or rejection of the materials in his own laboratory or elsewhere.

Total Materia has allowed us to solve in a definite way all problems we had for the search of alternate materials in foreign countries.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Purchasers desiring a guarantee of heavier coatings than the minimum thicknesses shown herein should use the special requirements see 4.

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. The thickness of coating thus obtained is the test article coating thickness. The weight of coating per unit area thus determined is converted to equivalent coating thickness values according to Table 2 rounding up or down as appropriate.
