Overview
ASTM D1998 covers the requirements and testing of polyethylene (PE) storage tanks used for above-ground storage of liquids. The standard defines material properties, design criteria, and performance requirements to ensure safe and reliable operation.
This method is widely used in chemical storage, water treatment, and industrial applications. It ensures that polyethylene tanks meet durability, strength, and environmental resistance requirements.
Scope, Applications, and Benefits
Scope
ASTM D1998 evaluates polyethylene storage tanks by defining performance requirements related to structural integrity, material properties, and environmental resistance.
The test evaluates:
- Structural strength and integrity of tanks
- Resistance to chemical and environmental exposure
- Material properties of polyethylene
- Dimensional stability under load
- Suitability for liquid storage applications
Applications
- Chemical storage tanks
- Water and wastewater storage systems
- Industrial liquid storage
- Agricultural storage tanks
- Food and beverage storage (non-potable)
- Environmental and process industries
Benefits
- Ensures safe storage of liquids
- Supports compliance with industry standards
- Helps prevent leakage and failure
- Assists in material and design validation
- Enables comparison of tank performance
Test Process
Sample Inspection
Tanks or material samples are inspected for dimensions and defects.
1Material Testing
Polyethylene properties such as density and strength are evaluated.
2Load Evaluation
Tanks are subjected to loading conditions to assess structural performance.
3Data Recording & Evaluation
Results are analyzed to verify compliance with ASTM requirements.
