Import Tips
• Verify casting material is ductile iron via mill test reports to confirm classification under cast fittings
• Include groove specifications (e.g
• Victaulic Style 77) in documentation to avoid misclassification as non-grooved
• Ensure pressure ratings meet ASTM A536 standards; common pitfall is incorrect end-use declaration for fire vs. water systems
