Which of the following is a standard used for assessing Low-Emitting Materials?

The selection of ASTM D5197 as the standard for assessing Low-Emitting Materials is accurate because this standard outlines specific methods for measuring the volatile organic compound (VOC) emissions from building materials and products. This standard is particularly relevant in the context of indoor air quality, as it helps determine the emissions of harmful substances from various materials used in construction.

The identification of low-emitting products is a critical aspect of LEED certification, as it directly contributes to improved indoor air quality and the health of occupants. ASTM D5197 provides a clear testing protocol that ensures consistency and reliability in the results, which is essential for projects seeking LEED certification in the category of Indoor Environmental Quality.

Other standards listed are less relevant to the assessment of low-emitting materials. British Standard 5228 relates primarily to noise and vibration control, while ISO 4224 defines terms associated with building products and materials but does not focus specifically on VOC emissions. ASTM D5149 pertains to the testing of emissions from photoluminescent materials, which is not directly connected to low-emitting materials in general. Thus, the emphasis on ASTM D5197 as the standard ensures a robust approach to assessing and certifying materials that will help in achieving LEED credits focused on
