What Is ASTM E1673 Pesticide Suspensibility?
ASTM E1673 provides a test method for determining the percent suspensibility of solid materials dispersed in a liquid medium. Suspensibility indicates the ability of particles to remain uniformly suspended without settling over time.
This standard is commonly used to evaluate formulations such as pesticides, coatings, and chemical suspensions, where stability and uniform distribution are critical.
Applications and Benefits of ASTM E1673 Pesticide Suspensibility Testing
Scope
ASTM E1673 focuses on measuring how well solid particles remain suspended in a liquid after agitation and a defined settling period. It ensures consistency and performance of suspension systems.
The test evaluates:
- Suspension stability
- Settling behavior of particles
- Uniformity of dispersion
- Formulation quality
- Suitability for application
Applications
- Agricultural chemicals (pesticides, herbicides)
- Paints and coatings
- Chemical suspensions
- Pharmaceutical suspensions
- Quality control laboratories
Benefits
- Ensures uniform product performance
- Improves formulation stability
- Reduces settling and separation issues
- Supports quality control
- Enables comparison of formulations
Our ASTM E1673 Testing Procedure
Sample Preparation
Suspension is prepared and mixed thoroughly.
1Settling Period
Sample is allowed to stand for a specified time.
2Sampling
Upper portion of suspension is carefully removed.
3Data Recording & Evaluation
Suspensibility is calculated based on remaining solids.

ASTM E1673 Pesticide Suspensibility FAQs
ASTM E1673 is a standard test method used to determine percent suspensibility of solid materials in liquid suspensions, evaluating how well particles remain uniformly dispersed over time.
ASTM E1673 is important because good suspensibility ensures consistent performance, prevents settling issues, and maintains uniformity in products like coatings, pesticides, and chemical formulations.
ASTM E1673 involves dispersing a material in liquid, allowing it to settle under controlled conditions, then measuring the amount of material remaining suspended after a specified time.
ASTM E1673 requires graduated cylinders, mixing devices, controlled environment, and measurement tools to evaluate suspension stability and quantify settled versus suspended material.
Results are reported as percentage of material remaining suspended, indicating stability of the formulation and suitability for applications requiring uniform dispersion over time.
