ASTM C50 – Standard Practice for Sampling, Sample Preparation, Packaging, and Marking of Lime and Limestone Products


ASTM C50 provides procedures for:

  • Sampling: collecting representative samples of lime and limestone products for testing. This includes methods for both incremental and random sampling.
  • Sample preparation: reducing the collected samples to a suitable size for laboratory testing.
  • Packaging: protecting the samples during transport to maintain their integrity.
  • Marking: labeling the samples with appropriate identification information.

The scope of ASTM C50 includes:

  • Materials: lime and limestone products used in chemical, agricultural, and process industries.
  • Processes covered: sampling, sample preparation, packaging, marking, inspection, rejection, and retesting.
  • Purpose: ensuring that the samples used for testing are representative of the entire lot or shipment, leading to accurate and reliable test results.

This standard is essential for quality control in the lime and limestone industry. By following ASTM C50, manufacturers and users can ensure that the products meet specified requirements and perform as expected in various applications.
