Significance and Use | ||||||
5.1 This test method is intended to evaluate whether sufficient salt (NaCl) has been retained by the hides or skins to slow down degradation by bacterial (enzymatic) action, and to slow down autolysis by inherent enzymatic action, until they are preserved by a tanning process. Note 2: Osmosis occurs during brine curing because moisture is
drawn out by salt through the epidermis.4
Low moisture (< 40 %) in the hides does not necessarily indicate
poor cure. A hide may have low moisture due to osmosis; to
increased fat content; or to drying out conditions. In all
instances the hides would still show adequate cure if the moisture
was saturated to approximately 85 % salt, because the ash: moisture
ratio would be adequate.

1. Scope | ||||||
1.1 This test method covers the estimation of degree of saturation of the brine content of cured (salt-preserved) hides and skins containing 40 % or more moisture. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
