ASTM D3374 – Standard Specification for Vinyl-Coated Glass Yarns (Withdrawn 2023)
Description:
Scope
1.1 This specification covers vinyl-coated glass yarns. These yarns are manufactured in two basic classes. These classes have been established that when properly woven into screening, satisfactory strength, durability, and insect protection are obtained. The two classes are as follows:
1.1.1 Class 1—Nominal thickness 0.292 mm [0.0115 in.].
1.1.2 Class 2—Nominal thickness 0.330 mm [0.0130 in.].
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
