VI. Grade Definitions
The definitions which follow describe grades as they should be sorted and packed. CONSIDERATION SHOULD BE GIVEN TO THE FACT THAT PAPER STOCK AS SUCH IS A SECONDARY MATERIAL PRODUCED MANUALLY AND MAY NOT BE TECHNICALLY PERFECT. Definitions may not specifically address all types of processes used in the manufacture of, or recycling of, paper products. Specific re-quirements should be discussed between buyer and seller during negotiations.

Outthrows
The term "Outthrows" as used throughout this section is de-fined as "all papers that are so manufactured or treated or are in such a form as to be unsuitable for consumption as the grade specified."

Prohibitive Materials
The term "Prohibitive Materials" as used throughout this sec-tion is defined as:
a. Any materials which by their presence in a packing of paper stock, in excess of the amount allowed, will make the packaging unusable as the grade specified.
b. Any materials that may be damaging to equipment. Note: The maximum quantity of "Outthrows" indicated in connection with the following grade definitions is un-derstood to be the TOTAL of "Outthrows" and "Pro-hibitive

Materials:
A material can be classified as an "Outthrow" in one grade and as a "Prohibitive Material" in another grade.
Carbon paper, for instance, is "UNSUITABLE" in Mixed Paper and is, therefore, classified as an "Outthrow;" where as it is "UNUSABLE" in White Ledger and in this case classified as a "Prohibitive Material:"

SPECIALTY GRADES
The grades listed at right are produced and traded in carload and truckload quantities throughout the United States, and because of certain characteris-tics (i.e., the presence of wet strength, polycoatings, plastic, foil, carbon pa-per,
hot melt glue), are not included in the regular grades of paper stock. However, it is recognized that many mills have special equipment and are able to utilize large quantities of these grades. Since many paper mills around the world do use these specialty grades, they are being listed with appropriate grade numbers for easy reference.
The Paper Stock Industries Chapter of ISRI is not establishing specific specifications, which would refer to such factors as the type of wet strength agent use, the percentage of wax, the amount of polycoating, whether it is on top of or under the printing, etc. The specification for each grade should be determined between buyer and seller, and it is recommended that pur-chase be made based on sample.

2-S Printed Waxed Cup Cuttings
