ASTM American Society for Testing & Materials
Angle of Friction (.Angle of friction benveen solid bodies.) (Degree) Angle whose
tangent is the ratio between the maximum value of shear stress that
resists slippage between two solid bodies at rest with respect to each
other, and the normal stress across the contact surfaces.
Bonded Seam Strength Strength of a seam of liner material measured either in shear or peel
modes. Strength of the seams is repotted either in absolute units:
e.g., pounds per inch of width; or as a percent of the strength of the
sheeting.
Breaking Strength Tensile force to break measured in pounds (Newton's) on a
supported or unsupported membrane.
Carbon Black Additive for elastomeric and plastic sheeting or film for ultraviolet
absorption and pigmentation. Typically I% to ?% of the base
product in the case of thermoplastics and crystalline thermoplastics,
and 10% to 4)% in the case of elastomers and thermoplastic
elastomers; impart a black color to the compound which retards
aging by ultraviolet light from the sun and increases the stiffness of
elastomeric compounds.
Crystallization, Polymer Arrangement of previously disordered polymer segments of
repeating patterns into geometric symmetry.
Density The mass per unit volume, (~IL~~)kg/ms[4].
Dimensional Change A generic term for changes in length or width of a fabric specimen
subjected to a specified condition.
Direct Sheaz Test A shear test in which soil or rock under an applied normal load is
stressed to failure by moving one section of the sample or sample
container (shear box) relative to the other section.
Dispersion I) A distribution of finely divided particles in a medium; for
example a colloidal suspension of a substance.
2) A qualitative estimation of the separation and uniform
distribution of fibers, typically in a water suspension for wet
forming.
