求翻译：样品应该在井口采集，并且粘度应该通过合适的实验测试进行监测。买方应该通过实验测试确保聚合物符合规范，供应商应该提出合适的粘度控制方法。是什么意思？

null

Samples should be collected on the wellheads and viscosity should be carried out by means of suitable test monitoring. The buyer should be through experiments normative polymer testing to ensure that suppliers should be a suitable viscosity control methods.

The sample should in well head gathering, and the viscosity should test through the appropriate experiment carries on the monitor.The buyer should test through the experiment guarantees the polymer to conform to the standard, the supplier should propose the appropriate viscosity control method.

Samples should be in the wellhead sampling and viscosity should be monitored through appropriate experimental tests. Buyer should ensure polymers through experimental testing within specification, vendors should make appropriate viscosity control methods.
