The COBB value indicates whether paper, paper board, or corrigated fiber board has the ability to absorb water. A high COBB value indicates the ability to absorb water, a low COBB value indicated resistance to absorbing water.
One can measure Cobb of kraft paper in lab following TAPPI T441 standard.
Ty Cobb had a lifetime batting average of .366
what is the cobb test value for coated test liner
The standard Cobb value of kraft paper is typically around 60-70 g/m². This value represents the amount of water that the paper can absorb in a specific time frame and is an important measure of the paper's ability to withstand wet conditions.
The COBB value of paper is typically measured in grams per square meter (g/m2). It represents the amount of water absorbed by a specific area of the paper surface in a standardized test, indicating the paper's resistance to liquid penetration.
The Cobb/sizing is comes under the MISCELLANEOUS PROPERTIES. If you do not want to use the old manual method. There do exists Automatic Cobb testers that also in addition to the static Cobb value for a given time, show you the dynamic Cobb value in a graph with time axis. It is for example many times, more relevant to see the water uptake after ten seconds and not after one minute.

The tolerance for Cobb value in the absorption of paper typically ranges from 10 to 30 g/m², depending on the type of paper and its intended use. The Cobb test measures the amount of water absorbed by paper over a specific time period, which helps assess its suitability for various applications, especially in packaging and printing. Higher Cobb values indicate greater water absorption, which may not be desirable for certain types of paper. Always refer to industry standards or specifications for specific tolerance levels.
The Cobb value measures the water absorption of paper and is typically expressed in grams per square meter (gsm). For 100 gsm paper, the Cobb value can vary depending on the specific type and treatment of the paper, but it generally ranges from 30 to 50 g/m² for standard papers. A lower Cobb value indicates better resistance to water absorption, which is often desired in printing and packaging applications. Always refer to the manufacturer's specifications for precise values.
For an MLB batting title, yes. In 1907, Cobb led the AL and Wagner led the NL with averages of .350. When not rounding the number of decimal points in the batting average Cobb had the better average. Cobb had 212 hits in 605 at bats for a .3504 average and Wagner had 180 hits in 515 at bats for a .3495 batting average which rounds to .350.
