Standard Test Method for Blocking

Standard Test Method for Blocking

ABSTRACT
This test method establishes the standard procedure for determining the resistance of leather to blocking under specific conditions of temperature, humidity, and pressure. This method is not applicable to wet blue. This procedure requires the use of a forced circulating hot air oven, American Medical Museum jar with lid, Petri dish with cover, and weights.
SCOPE
1.1 This test method covers determination of the resistance of leather to blocking under specific conditions of temperature, humidity, and pressure. This test method does not apply to wet blue.
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.

ASTM D7340-07(2023)(Practice)
Standard Practice for Thermal Conductivity of Leather

SIGNIFICANCE AND USE
5.1 Part of the function of a shoe is to assist the foot in maintaining body temperature and to guard against large heat changes. The insulating property of a material used in shoe construction is dependent on porosity or the amount of air spaces present. A good insulating material has a low thermal conductivity value, k. The thermal conductivity value increases with an increase in moisture content since the k value for water is high, 0.0014 cal/s cm · °C (0.59 W/m·K).
SCOPE
1.1 This practice is intended to determine the thermal conductivity of a sheet material. This practice is not limited to leather, but may be used for any poorly conductive material such as rubber, textile and cork associated with the construction of shoes.  
1.2 A constant heat source is sandwiched between two identical metal cylinders which are mounted with their axes vertical. A test specimen is placed on the top surface of the upper cylinder and a third identical metal cylinder is placed on top of the test specimen so that all the cylinders and the test specimen are concentrically aligned (see Fig. 1). The heat source is switched on and the temperatures of the three blocks allowed to reach equilibrium. The thermal conductivity of the test specimen is then determined from the steady-state temperatures of the three blocks, the exposed surface areas of the blocks and test specimen and the thickness of the test specimen.

1.3 This practice does not apply to wet blue.  
1.4 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.  
1.5 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.

Standard Test Method for Hexane Extraction of Leather

SIGNIFICANCE AND USE
3.1 This test method measures the amount of hexane-soluble lubricant present in all types of leather. Adequate lubrication prevents abrasion of leather fibers during flexing. This lubrication is generally obtained from the fat liquor added at the tannery. Some lubrication is also obtained from natural grease produced during the life of the animal.
SCOPE

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

ASTM D8042-18(2023)(Test Method)
Test Method for Shrinkage Temperature of Wet Blue and Wet White

SIGNIFICANCE AND USE
5.1 This test method is designed to determine the temperature at which the Wet Blue or Wet White specimen experiences shrinkage. In this test method, shrinkage occurs as a result of hydrothermal denaturation of the collagen protein molecules which make up the fiber structure of the Wet Blue or Wet White. The shrinkage temperature of Wet Blue or Wet White is influenced by many different factors, most of which appear to affect the number and nature of crosslinking interactions between adjacent polypeptide chains of the collagen protein molecules. The value of the shrinkage temperature of Wet Blue or Wet White is commonly used as an indicator of the type of tannage or the degree of tannage, or both, of that particular Wet Blue or Wet White (especially for the more hydrothermally stable tannages such as chrome tannage).
SCOPE
1.1 This test method covers the determination of the shrinkage temperature of all types of Wet Blue and Wet White. The heating medium is water when the shrinkage temperature is at or below 98 °C. The heating medium is a glycerine-water solution when the shrinkage temperature is above 98 °C.  
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.  
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.

SIGNIFICANCE AND USE
3.1 The procedure is intended primarily to evaluate garment-type leathers. The test method is qualitative and measures the surface-water repellency or surface-water resistance only. It is not intended for use in determining resistance to water penetration. A visual means is given to evaluate the relative effects of materials showing water repellency, but no comparison is possible with conditions found in actual use.
SCOPE
1.1 This test method covers the qualitative evaluation of the surface repellency to water of garment-type leathers. This test method does not apply to wet blue.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values shown in parentheses are provided for information only.  
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.

Standard Test Method for Resistance of Shoe Upper Leather to Artificial Perspiration

SIGNIFICANCE AND USE
3.1 This test method gives an indication of the serviceability of shoe upper leather in actual wear.
SCOPE
1.1 This test method covers the determination of the effect of perspiration on shoe upper leather. The leather is subjected to treatment with a formulation of artificial perspiration specific for breakdown of leather. Resistance to grain cracking as measured in accordance with Test Method D2210 and area loss are used as the criterion of deterioration. The artificial perspiration may also affect the flexibility of the leather. However, these effects have not been fully evaluated as criteria of deterioration in this test method. This test method does not apply to wet blue.  
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.
