D6213-17 – Standard Test Method Technical Guide
ASTM D6213-17 provides standardized procedures for evaluating the chemical resistance of geogrids when exposed to liquids. This practice outlines methods to measure changes in physical and mechanical properties after immersion in test solutions representative of end-use conditions. It is designed to be used alongside Practice D5322 for laboratory immersion or Practice D5496 for in-field testing.
📐 Test Methods and Parameters
This practice references several ASTM standards for specific test procedures. The following table lists key methods for assessing geogrid properties before and after liquid exposure:
| 🟦 Standard | 📏 Description |
|---|---|
| D4595 | Test Method for Tensile Properties of Geotextiles by the Wide-Width Strip Method |
| D5322 | Practice for Laboratory Immersion Procedures for Evaluating the Chemical Resistance of Geosynthetics to Liquids |
| D5496 | Practice for In Field Immersion Testing of Geosynthetics |
| D1238 | Test Method for Melt Flow Rates of Thermoplastics by Extrusion Plastometer |
| D4603 | Test Method for Determining Inherent Viscosity of Poly(Ethylene Terephthalate) (PET) by Glass Capillary Viscometer |
These methods allow for comprehensive evaluation of mechanical and chemical property changes in geogrid coupons after liquid exposure.
⚙️ Procedure and Exposure Conditions
Section 4.1 of the practice summarizes that geogrid coupons are immersed in test liquids, and their physical condition is monitored over cumulative exposure time. Monitoring includes visual observations, mechanical tests, and chemical property tests. The practice is used to determine the resistance of geogrids to liquid exposure by tracking changes in these properties.
Exposure conditions should be representative of anticipated end-use environments, and testing procedures must comply with safety precautions outlined in Section 7. The following table illustrates some monitoring parameters:
| 🟦 Monitoring Aspect | 📐 Examples from Standard |
|---|---|
| Physical | Visual condition, dimensional stability |
| Mechanical | Tensile strength (D4595), elongation |
| Chemical | Melt flow rate (D1238), inherent viscosity (D4603) |
This structured approach ensures consistent evaluation of chemical resistance across different laboratories and applications.
💡 Tip: Always use D6213-17 in conjunction with D5322 or D5496 for complete immersion testing procedures. This practice focuses on reporting and testing of coupons, while companion standards cover immersion protocols.
⚡ Note: Per Section 1.4, evaluation or interpretation of test data is beyond the scope of this practice. Users must establish their own analysis protocols for data interpretation.
