EIGA Document 221/19 – Method for characterizing acceptance criteria due to mechanical impacts on composite cylinders.
Cylinders of composite construction are sensitive to mechanical impact damage, especially when carbon fibre is used. Damage due to mechanical impact(s) require further investigations to quantify damage severity.
This publication gives a method to establish the acceptance criteria for impact damage on Type 3 and Type 4 cylinders and tubes and specifies the tests to be performed for producing pictures of acceptable and non-acceptable defects. The publication is intended to supplement EN ISO 11623, Gas cylinders - Composite construction - Periodic inspection and testing.
