En 8 Stands for Euro - NOrm
CML on a PVC pipe typically stands for "Certified Material List." This designation indicates that the pipe meets specific quality and material standards, ensuring it is suitable for its intended applications, such as plumbing or drainage. The certification helps ensure safety and compliance with industry regulations.
ASTM A 351 Gr CF8 stands for cast 304 material and CF8M stands for cast SS 316
CF8M and SS 316 are not identical but are closely related. CF8M is a casting designation for stainless steel that is equivalent to ASTM A351 Grade CF8M, which is a type of austenitic stainless steel often used for valves and fittings. SS 316, or ASTM A276/Austenitic stainless steel 316, is a wrought material commonly used in various applications. Both contain similar alloying elements, but their properties can differ due to their manufacturing processes.
Stainless Steel version
CF8M is a low-carbon version of CF8, which are both types of stainless steel. CF8M has a higher chromium and nickel content, making it more corrosion resistant than CF8. CF8 is often used in applications where corrosion resistance is less critical compared to CF8M.

CF8M and CF8 are both grades of stainless steel, primarily used in casting. The main difference lies in their chemical composition; CF8M contains a higher percentage of molybdenum, which enhances its corrosion resistance, especially against chlorides. CF8, on the other hand, has a lower molybdenum content and is typically less resistant to pitting and crevice corrosion. This makes CF8M more suitable for harsher environments compared to CF8.

As I was best able to determine, it stands for "Material of Construction" in Plumbing/engineering speak.
A351-CF8M refers to a specific grade of stainless steel defined by the ASTM A351 standard, which outlines the chemical and mechanical properties of cast stainless steels. The "CF8M" designation indicates that the alloy is austenitic, containing approximately 18% chromium and 10% nickel, with the addition of molybdenum for enhanced corrosion resistance. This grade is often used in applications requiring good strength and resistance to pitting and crevice corrosion, such as in chemical processing and marine environments.
