SA 2.5 SAND AND SHOT BLASTING RUBERT CHART SUPPLIER IN RAJKOT
RUBERT SA 2.5 SAND & SHOT BLASTING SURFACE COMPARATOR The RUBERT No. 017 Shot-Blasting Comparator is designed for checking the surface roughness/profile of steel surfaces after shot blasting before painting or coating. RUBERT states that its No. 017 and No. 018 comparators are designed for surfaces blast-cleaned to Sa 2½ and Sa 3 and conform to ISO 8503. Technical Specification Parameter Specification Product Name SA 2.5 Sand & Shot Blasting Surface Comparator Brand RUBERT Origin England / UK Type Surface Roughness / Blast Profile Comparator Comparator Material Precision Nickel Comparator Plate Application Shot blasting / blast-cleaned steel surface Surface Profile Dimpled profile for shot blasting Cleaning Grades Sa 2½ and Sa 3 Profile Segments 4 reference sections Segment 1 25 µm Segment 2 40 µm Segment 3 70 µm Segment 4 100 µm Profile Classification Fine / Medium / Coarse Standard ISO 8503 Measurement Method Visual and tactile comparison Typical Use Surface preparation inspection before painting/coating Packaging Protective case/wallet The four shot-blast reference profiles are 25, 40, 70 and 100 µm. Independent product documentation identifies the comparator as conforming to ISO 8503-1, ISO 8503-2 and ASTM D4417. Fine / Medium / Coarse Classification Fine: 25 to <40 µm Medium: 40 to <70 µm Coarse: 70 to <100 µm This comparator is intended for comparison of blast profile, rather than replacing an instrument-based quantitative roughness measurement. RUBERT Item No.: 017 — Shot Blasting Comparator RUBERT Item No.: 018 — Grit/Sand Blasting Comparator
