Guidelines for Tire

Scrap: TS-2016

Rubber From Scrap Tires

General Guidelines

Items not covered in the specifications, and any variations

in the specification are subject to special arrangement

between Buyer and Seller. Percentages listed below are by

weight.

Definitions

Fines consist of materials that pass a 4.75 mm sieve. These

materials may include rubber, fiber, inorganic and organic

matter, dirt, and other non-tire materials.

Sizes will be determined by sieving. Suitable sieve sizes will

be selected. Nest the sieves in order of decreasing size of

opening from top to bottom and place the sample on the top

sieve. Agitate the sieves by hand or by mechanical appara-

tus for a sufficient period so that additional sieving does not

result in substantial additional material passing through the

sieves.

TDM refers to tire-derived material.
