WWW Computer Program for Calculating Strength Ratios from Failure Codes in ASTM D4761, Table X1.1.

This program calculates strength ratios from failure codes in ASTM D 4761 Table X1.1. These codes are of the form 'XX-YY', where XX is a 2-digit code showing the characteristic associated with a failure and YY is a 2-digit code describing the extent of the characteristic. Some examples are: 15-08 is a 1/2 inch wide face knot, center line encased. 51-12 is slope of grain 1 inch for every 12 inches. See ASTM D 4761 Table X1.1 for a complete list of failure codes.
This program will read a data set with the following format:

WARNING!! You must have data for each variable. If data is missing, you must enter a period ( . ) to hold its place. If not, the program will put a 0.000 in its place when it writes out the results. This could cause you further problems in future calculations.

Before you proceed, you must transfer this datafile to www1.fpl.fs.fed.us via anonymous ftp. You must place it in the pub/data directory. (If ftp does not run on your machine, e-mail your data to the address given below and it will be placed in the directory.)

The program will calculate a strength ratio for each specimen, and write it out, along with your original input data, to a file that has your original filename with an extension of .res added to it. (For example, if you sent a data set called himom, you will get back a data set called himom.res.) You can then retrieve your file via anonymous ftp from the pub/data directory.

Please enter the name of the data set you have put in our /pub/data directory for which you would like estimated percentiles.
