ISO 6259-3 Thermoplastics pipes -- Determination of tensile properties -- Part 3: Polyolefin pipes
ISO 6259-3:2015 specifies a method of determining the tensile properties of polyolefin (polyethylene, cross-linked polyethylene, polypropylene, and polybutene) pipes, and the following properties: the stress at yield and the elongation at break.
Sample size:
Type 1 Dog bone : 150mm length, 20mm width
Type 2 Dumbell : 115mm length, 20mm width
Type 3: 250mm length
Pipe thickness less 5mm, use type 2 sample.
5-12mm thickness, use type 1 sample.
12-25mm thickness, use type 1 sample or type 3 sample.
large than 25mm thickness, use type 3 sample.
