球囊管：球囊的壁厚有着严格的尺寸公差要求。尺寸越大要求耐压性越大
| 球囊导管材料 | 尺寸公差 |
| Pebax® (7033 or 7233) | ± .0005" to .001" |
| Polyamide 12 (PA12) | ± .0004" to .0008" |
| LDPE or LLDPE | ± .001" |
| Polyurethane | ± .001" + |
挤出管检测方式
| •工序间检查 |
| •临界尺寸 |
| •外观检查 |
| •抽样方案 |
| •N=1 需要时每30分钟甚至更短时间抽样 |
| •短期（1小时或者更少），用AQL C=0抽样方案 |
| •对线轴而言，则是在开始和结束抽样 |
| •产品批量鉴别 |
| •根据机种，捆束或者线轴排序号 |
| •视觉检测 | ||||||
| •18“ 间隔 (臂长), 正常室内光线下, 3-5 /秒每件，特殊指定产品除外。 | ||||||
| •颗粒估量表TAPPI T213 和 T437 用于限制胶质、白点和杂质含量。 | ||||||
| •0.2 mm2 的胶质尺寸为内部标准。 | ||||||
| •显微镜检查10-20X (必要时) | ||||||
| •对于颜色测量, 使用Pantone Matching System彩通配色系统 (PMS) 色标卡。 | ||||||
| ± 1 色差，除非特殊要求 | ||||||
