Ball Burst and Puncture Resistance Testing

Ball burst (ISO 13938-2, steel ball 25 mm diameter, 30 mm aperture, 100 mm/min CRE) and puncture resistance (ISO 12236 CBR puncture, 50 mm diameter flat-ended piston, 50 mm/min) measure fabric resistance to localised force penetration simulating sharp object impact, rock puncture in geotextile installation, and needle penetration in medical textile applications. Ball burst force ranges: single jersey cotton (160 g/m²): 80–150 N; woven PET industrial (300 g/m²): 250–450 N; needle-punched geotextile PP (200 g/m²): 800–1,500 N; woven HDPE geomembrane (300 g/m²): 1,200–2,500 N. CBR puncture (ISO 12236, most widely used geotextile puncture test): needle-punched PP geotextile 200 g/m² minimum 1,000 N; 400 g/m² minimum 2,500 N; woven geotextile 300 g/m² minimum 4,000 N — puncture resistance is specified in geotextile installation specifications because angular aggregate particles during placement apply concentrated puncture loads. Dynamic puncture resistance (ISO 13428, drop cone method: 50 mm diameter cone dropped from 500 mm height onto clamped fabric, measure hole diameter or cone penetration depth — geomembrane acceptance criterion: cone penetration <0 mm, no hole formation at 1 kg cone drop). Probe puncture resistance (EN 388 mechanical protection standard, adapted for cut protection: cone probe force to penetrate 2.5 mm — classifies puncture protection levels 1–4 for work gloves and protective garments). Modified ball burst for protective textiles (ASTM F1342, probe force to penetrate protective clothing by 5 mm — medical protective gloves minimum 8 N puncture resistance per EN 455-4).
