    Withdrawn Rationale:

    These test methods cover tests for shellac in the dry button or powder form to be used for electrical insulating purposes. Typically, shellac is used as a bonding agent for mica splittings and reconstituted mica paper products, or as a coating or adhesive for other material.

    Formerly under the jurisdiction of Committee 09 on Electrical and Electronic Insulating Materials, this test method was withdrawn in November 2013. This standard is being withdrawn without replacement because the products referenced in this standard are no longer used in the electrical industry.

    1. Scope

    1.1 These test methods cover tests for shellac in the dry button or powder form to be used for electrical insulating purposes. Typically, shellac is used as a bonding agent for mica splittings and reconstituted mica paper products, or as a coating or adhesive for other material.

    1.2 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.

    Note 1—There is no similar or equivalent IEC standard.

    1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
