Significance and Use
This practice is to be used to provide a visual means of determining the existence of pinholes by penetration of a dye solution through the pinhole into a white receptor paper.
The practice is suitable for manufacturing control and will give close correlation with the end product.
This practice is suitable for comparative service evaluation and development.
The initial appearance will change with time due to continued migration of dye solution into the receptor paper and the size of the colored areas will not represent the actual size of the pinholes through which the solution was exuded.
1.1 This practice covers the determination of the existence of pinholes in one-time carbonizing tissues.
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 whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
