Which standard defines surface roughness for thermally cut surfaces?

• A. ISO 9001
• B. CSA W59
• C. ASTM A36
• D. CSA B95

Answer: (D)

Surface finish on edges created by thermal cutting is controlled by a standard that specifies how rough the cut surface may be. The standard that defines these surface roughness requirements for thermally cut surfaces is CSA B95. This standard focuses on the finish of cuts used in fabrication so they can be properly cleaned, beveled, or welded without issues caused by burrs, slag, or excessive roughness. ISO 9001 is about quality management systems and doesn’t set finish tolerances; CSA W59 is the welding code that governs weld quality and procedures but doesn’t specify the exact roughness for thermally cut edges; ASTM A36 defines the material composition and properties, not cutting finish. CSA B95 is the one that provides the surface finish criteria for thermally cut surfaces, making it the correct reference.
