According to IS 15455 Clause 6.2, permissible defects in split canes include blemishes, scars, pinholes, checks, and bruises. The extent of such defects varies by grade: Grade I must be completely free of defects and have a whitish color, while Grade II allows defects up to 15% of the standard cane length and can be white, yellowish, or brown. Each cane is inspected individually with a minimum of 10% of the lot sampled for uniformity. Lengths are measured as the shortest distance between ends, rounded down to the nearest 0.05 meters. This grading system ensures both the appearance and structural quality of the canes.
IS 15455 classifies split canes into two grades based on appearance and defect allowance: Grade I includes canes that are entirely free from defects and have a whitish hue; Grade II includes canes with permissible defects not exceeding 15% of the standard length, and colors that may range from white to yellowish or brown. The standard mandates individual inspection, with at least 10% of the batch checked for consistent sizing. Length measurements are taken as the shortest distance between cane ends and rounded down to the nearest 0.05 m, ensuring uniformity in grading and quality control.
Per IS 15455, round cane cores should have diameters ranging between 2 mm and 10 mm with a permissible tolerance of ±0.5 mm, maintaining uniform diameter along their length. Flat and oval cores have width dimensions between 2 mm and 10 mm, and thickness between 1 mm and 6 mm, both required to be consistent throughout the cane’s length. This dimensional uniformity is vital for ensuring consistent quality and performance in practical applications.
The standard outlines that at least 10% of the split cane lot must be randomly sampled for size uniformity. Each individual cane should be inspected to identify permissible defects such as blemishes, scars, pinholes, checks, and bruises, which must not exceed 15% of the standard length for Grade II canes; Grade I canes must be defect-free and whitish in color. Canes should be assessed for uniform color and luster. Based on these inspections, canes are classified into Grade I or Grade II, ensuring quality and consistency in the product.
IS 15455 Clause 10 specifies that split canes should be sorted by diameter or width and grade, then bundled and clearly marked. Each bundle must bear labels indicating the trade or vernacular name, botanical name, size dimensions (diameter/width and thickness), origin or source, supplier's name and address, and the supply date. Additionally, at least 10% of the lot must be randomly inspected for size uniformity, and length measurements must be rounded down to the nearest 0.05 meters as per buyer specifications. These protocols ensure traceability and maintain quality standards during trade.
