Standard Test Method for Chemical Resistance of Protective Linings
 N ASTM C868

Annotation

This test method covers a procedure for evaluating the chemical resistance of a polymer-based protective lining in immersion service. The method closely approximates the service conditions, including the temperature differential between the external and internal surfaces of the equipment, which may accelerate permeation of the lining by a corrosive media.

This test may be used to simulate actual field use conditions insofar as a qualitative evaluation of the lining system after a predetermined period of exposure.

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.

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.

Метод стандартной пробы для химической стойкости защитных подкладок

Этот метод испытаний покрывает процедуру для оценки химической стойкости основанной на полимере защитной подкладки в иммерсионном обслуживании. Метод тесно приближает рабочие условия, включая температурный дифференциал между наружными и внутренними поверхностями оборудования, которое может ускорить проникание выстилания коррозионные среды.
