USP | Mecmesin

Chapter 671 of USP (United States Pharmacopeia) provides standards for the functional properties of packaging systems used for solid oral dosage forms (SODF) and liquid oral dosage forms (LODF) for pharmaceuticals and dietary supplements.

Torque testing is required as part of Method 1 to perform the 'moisture vapor transmission test method' used for the 'Barrier Protection Determination of Packaging Systems'.

Moisture permeation and light-permeation testing, and application torque for screw-type containers.

Before conducting Chapter 671 of USP, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.

Test summary

This standard gives instructions for the testing of moisture vapour transmission and spectral transmission of plastic containers. The tests are carried out by gravimetric analysis, and by light adsorption measured in a spectrophotometer. As part of the test, the plastic containers are required to be tightened to a specified closure torque. Mecmesin equipment can be used to apply the required closure torque.
