3 terms and definitions
The following terms and definitions apply to this document.
3.1
Volume defective volumedefects
Plastic welds have three-dimensional defects; the defects are classified according to the three-dimensional shape characteristics, such as pores, slag.
3.2
Area defects areadefects
Plastic welds have a two-dimensional or third dimension of a very small defect; the defects are classified by planar shape features such as cracks,
Face to face.
3.3
