purity standards

Purity standards refer to the specific clarity, quality, and composition requirements that a substance, such as gasoline or chemicals, must meet to ensure safety and effectiveness. These standards define how much of the desired product is present and limit the amount of impurities or contaminants. Meeting purity standards ensures the product performs as intended without causing harm or damage, and helps maintain consistency, quality, and safety for consumers and industries. Essentially, they set the acceptable limits to guarantee a high-quality, reliable product.
