D5047-17 – Standard Test Method Technical Guide
📐 Scope and Material Requirements
This specification covers requirements for biaxially oriented polyethylene terephthalate (PET) film and sheeting with thicknesses from 1.5 µm (0.06 mil) to 355 µm (14.0 mil). The material shall consist of at least 90 % PET homopolymer derived from terephthalic acid and ethylene glycol. This specification does not apply to coated, coextruded, tinted, pigmented, or metallized film or sheeting.
Reapproved in 2023, this standard allows the use of reprocessable and recyclable PET materials, provided that any specific requirements as governed by the producer and end user are met.
Values stated in SI units are standard, with parentheses for information only. There is no known ISO equivalent to this specification. The standard was developed in accordance with internationally recognized principles on standardization.
⚙️ Test Methods and Procedures
The standard references numerous ASTM test methods for evaluating mechanical, physical, and electrical properties. These methods ensure consistent and reliable performance measurements across various applications.
| 🟦 Standard | 📏 Description |
|---|---|
| D882 | Tensile Properties of Thin Plastic Sheeting |
| D1004 | Tear Resistance (Graves Tear) of Plastic Film and Sheeting |
| D1505 | Density of Plastics by Density-Gradient Technique |
| D3985 | Oxygen Gas Transmission Rate Through Plastic Film and Sheeting |
| E96/E96M | Water Vapor Transmission Rate of Materials |
| D149 | Dielectric Breakdown Voltage and Dielectric Strength |
| D150 | AC Loss Characteristics and Permittivity |
Film is defined as sheeting with a thickness of ≤250 microns (0.010 in.) per Note 2, which helps in selecting appropriate test methods for thin materials.
📊 Key Measurable Properties
Critical properties such as tensile strength, tear resistance, density, gas transmission rates, and electrical insulation are assessed using the referenced methods. These include D882, D1004, D1505, D3985, D149, and D150, among others.
Additional properties like coefficients of friction (D1894), folding endurance (D2176), burst strength (D774/D774M), and propagation tear resistance (D1922) are also covered. Physical dimensions are measured per D5947 or D6988.
