    Significance and Use

    21.1 This test method covers determination of the total tin in the sample tested and does not apportion the tin to one or the other side of the test specimen. The calculations appearing in Section 27 assume uniform distribution of tin over the two surfaces.

    21.2 This test method does not differentiate between free tin on the tinplate surface, tin combined with iron in the intermediate alloy layer, or tin alloyed with the steel as a residual tramp element.

    1. Scope

    1.1 These test methods include four methods for the determination of tin coating weights for electrolytic tin plate as follows:

    Test Method


    A—Bendix Test Method

    3 to 9

    B—Constant-Current, Electrolytic Test Method (Referee Method)

    10 to 18

    C—Sellar's Test Method

    19 to 28

    D—Titration Test Method

    29 to 37

    1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
