Standard Number
TAPPI T494

Standard Title
Tensile Properties of Paper and Paperboard, Test Method

Overview:

TAPPI T494 Test Method details the method of obtaining the maximum tensile force per unit width measurement of paper. Ideal for identifying physical strength issues and resistance to web breaking. Purple Diamond Testing offers TAPPI T494 Tensile Properties of Paper and Paperboard as part of our packaging compliance and validation services.

Rationale:

TAPPI T494 – Tensile Properties of Paper and Paperboard. Data collected indicates the quality of the fiber strength, fiber length, and bonding of paper which could identify possible issues in meeting expectations when combined into corrugated boxes. This test method can be used to compare different paper grades, virgin fibers versus recycled fibers, manufacturers, and more. It’s also possible to evaluate how the paper’s tensile strength changes when exposed to different environmental conditions such as high humidity.
