This standard is mainly applicable to the determination of vitrinite reflectance in organic matter enriched after processing in sedimentary rock samples. It is also applicable to the reflectance determination of dispersed carbon debris, coal inclusions, asphalt, etc. in mudstone, sandstone, and limestone with high organic matter content. .
