Introduction

ASTM International developed the ASTM D1353 nonvolatile test method to quantify the nonvolatile residue present in volatile solvents used in coatings of nonvolatile related materials. The test quantifies the number of nonvolatile substances that might influence the solvent’s purity nonvolatile. By careful evaporation of a measured quantity of the solvent and analysis of residues that are left, ASTM D1353 provides a reliable determination of the content not volatile by ensuring consistent application wherever there is a need for a precise composition of the solvent. The standard has considerable usage in terms of quality control and regulatory compliance to determine the cleanliness and stability of solvents across a spectrum of industries.

Scope

The scope encompasses the quantitative determination of residual residue in organic fluids for ASTM D1353, which is meant for breaking down substances in manufacturers, including paints, coatings, and chemical manufacturing. These preformed contents are essential in the analysis of solvent purity and the extent to which the solvent can be used for the intended applications. This also ensures that the final products meet very stringent industrial standards.

Procedure

In the ASTM D1353 test, the following steps involve controlled evaporation of a known solvent volume and the weighed residue afterward. The residue is referred to as the nonvolatile content of the material. Since the test is susceptible to nonvolatile on specific temperature and evaporation technique conditions under which the test results are repeated and reproducible. Measure a desired volume of solvent in the range of 50 to 100 mL and pour this carefully into the pre-weighed container. To ensure consistent evaporation, place the container with the solvent in a controlled environment, often at a specified temperature (typically 105°C). To avoid contamination, conduct the evaporation in a well-ventilated area, ideally in an oven. After complete evaporation, cool the container in a desiccator to prevent moisture absorption, then reweigh it to determine the residue mass.

Following these steps, ASTM D1353 provides a reliable method for measuring nonvolatile residue in volatile solvents, guaranteeing uniform and nonvolatile results among testing laboratories.

Sample Size

The following are the technical specifications of ASTM D1353:

Sample size

In ASTM D1353, the sample size typically ranges from 50 to 100 mL of the volatile solvent being tested. However, the exact amount may vary based on the solvent’s volatility and expected residue content.

For highly volatile or low-residue solvents, a larger sample may be necessary to measure nonvolatile residue accurately.

Sample preparation

Use a clean, nonvolatile with a known weight, typically a glass or metal dish. The container should be able to withstand the evaporation process without contamination.

Accurately weigh the container before adding the solvent sample. Record this initial weight to determine the mass of any residue after evaporation.

Result

This test method covers determining the nonvolatile matter in volatile solvents for use in paint, varnish, and nonvolatile-related products.

Conclusion

The ASTM D1353 test is essential for industries requiring high-purity solvents. Accurate determination of the amount of nonvolatile matter will ensure that products perform nonvolatile and comply with regulatory standards. This test method analyzes residual materials in solvents that are 100% volatile at 105 ± 5°C. Volatile solvents manufacture paint, varnish, lacquer, and related goods, and any residue can affect product quality or process efficiency. This test method assists the manufacturer in controlling and determining compliance with standards.

FAQs

What is meant by nonvolatile matter?

Nonvolatile substances do not vaporize rapidly. They don't have a higher vapor pressure at the average room temperature and pressure. At room temperature, they will mostly be solids. Sodium chloride and silver nitrate are nonvolatile compounds.

What is the nonvolatile residue test method?

NVR determination involves evaporating the organic solvent and measuring the residue by weight using a sensitive balance and a carefully tared weighing vessel. This is the primary type of analysis used in the pharmaceutical industry.

How do you calculate volatile matter?

Volatile matter is determined as the loss in mass, less than due to moisture, when a sample is heated at 900 degrees Celsius for 7 minutes. This procedure is undertaken out of contact with air under standardized conditions.
