No cracks or breaks in the base metal shall occur until the distance between the plates is less than one third of the original outside diameter of the tubing, but in no case less than five times the thickness of the tubing wall. Evidence of lamination or burnt material shall not develop during the flattening process, and the weld shall not show injurious defects. 在两个压板之间的距离小于管子原始直径的三分之二前，焊缝不应有开裂；在两 个压板之间的距离小于管子原始直径的三分之一前（在任何情况下，板间距离不 得低于管子壁厚的 5 倍），基体材料不得有开裂或者裂纹。在压扁过程中，不应 有材料分层或者烧伤的现象，且焊缝不应有损伤缺陷。 Test frequency: 2 psc per lot. 试验频率：2 支每批。
