•Find the volume of 5 containers using water. •Calculate the moisture permeability in mg/day/L by the formula: P = (1000/14V)[(Tf-Ti)-(Cf-Ci)] where V is the volume of container in mL, (Tf-Ti) is the difference, in mg, between the final and initial weights of each test container and (Cf-Ci) is the difference, in mg, between the average finalThe tests that follow are provided to determine the moisture permeability of containers utilized for drugs being dispensed on prescription.The section Multiple-Unit Containers for Capsules and Tablets applies to multiple-unit containers (see Preservation, Packaging, Storage, and Labeling under General Notices and Requirements).The section Single-Unit Containers and Unit-Dose .When determining the specific USP <671> permeation testing. . low-barrier containers can be properly measured over time assuming sufficient water is present in the cavity at test start. MVTR Results are reported in average mg/day/cavity and must include the standard deviation of the 10 samples (test units).
The average rate of moisture vapor transmission (mg.day −1.L −1) determined at 23 °C/75%RH, as established by USP methodology [14] (Table 4) showed that the glass and PET bottles could be classified as “tight” since none of the units evaluated exceeded the specification of 100 mg.day −1.L −1 for moisture permeability.Two general types of permeability test methods are routinely performed in the laboratory: (1) the constant head test method, and (2) the falling head test method. The constant head test method is used for cohesionless and more permeable soils (k>10-4 cm/s) and the falling head test is mainly used for cohesive or less permeable soils (k<10-4 cm .
USP Chapter <671> should be rewritten or replaced. For the purpose of moisture-barrier comparison, WVTR testing should be conducted at 40oC/75% RH The test duration should be 35 days, and containers weighed at 7 day intervals WVTR should be calculated by regression analysis over the period from day 7 to day 35 (5 data points).
• From WVP, (Water Vapor) Permeability is calculated for homogeneous materials such as insulation Note: Water vapor permeance is the technically correct term; permeance is . WATER 73°F / 50% RH TEST ENVIRONMENT = 0.41 in. Hg or 0.2 psi Partial vapor pressures indicated, except in reservoir which is at saturation vapor pressure due to 100 .These tests determine the moisture vapor transmission rate (MVTR) i.e., water vapor permeation rate, for plastic packaging systems for manufacturers, packagers, and repackagers (Table 1). .

Oxygen permeability testing is made in accordance with ASTM D-3985, ASTM F-1927 and ASTM F-1307, DIN 53380-3 or JIS K 7126. . DIN 53380-3 or JIS K 7126. Water vapor permeability rates can be determined according to ASTM F1249, BS 7406 method A, ISO 9932 or TAPPI T557. Other standards for WVTR based on pack or dish methods include USP <671 .Muttenz, October 5, 2017 – Clariant, a world leader in Specialty Chemicals, with its Healthcare Packaging business unit, is introducing Tri-Sorb molecular sieve desiccant tablets specifically designed for USP moisture permeability testing at several upcoming industry events.
Permeability and sealing; 2.2 b. Potency and impurity content; 2.3 c. Weight variation test. 2.3.1 d. Weight variation test for hard gelatin capsules; . Moisture permeation test. The USP requires determination of the moisture-permeation characteristics of single-unit and unit dose containers to assure their suitability for packaging capsules . a) Water vapour permeability- the water vapour permeability of the pack containing the product is required. This is necessary because although the bottles will comply with the water vapour permeability test described in USP, permeation through the bottle wall will depend on wheather the product has a high or low affinity for the water.

Water Vapor Transmission Rate (WVTR) testing was performed to construct weight gain profiles due to moisture ingress of formed and sealed blisters (PVC, PVDC, Aclar Ultrx 2000 . determine the potential to improve USP <671> by determining the time needed to reach steady state, the duration, and number of data points needed for WVTR calculation .Replacing the heavy metals attribute was considered unnecessary because (a) the source water specifications (found in the NPDWR) for individual Heavy metals were tighter than the approximate limit of detection of the Heavy metals test for USP XXII Water for Injection and Purified Water (approximately 0.1 ppm), (b) contemporary water system . Compendial methods for determination of moisture permeation are currently described in the USP〈671〉 (USP29-NF24) for dispensing of pharmaceutical products. . Container moisture permeability measured by steady-state weight gain method is based on an assumption that a “sink” condition exists for water vapor in the container headspace . The USP published a draft of a new general chapter on the Application of Moisture Vapor Transmission Rates for Solid Oral Dosage Forms in Plastic Packaging Systems. Additionally the general chapter Containers—Performance Testing <671> has been revised and published for comment in the same issue of PF.
The plastic bottles were randomly selected from supplier A, B and C. Results: The plastic bottles from supplier A and B had an average moisture permeability of 12.57 and 51.55 mg/day/L with none .Water vapor permeability of these membranes is the key parameter for establishing their performance. Various techniques exist to measure the water vapor permeability in membranes of different types and characteristics. The most commonly used is the cup test based on the standards published by The American Society for Testing and Materials With USP 41 - NF 36 the revised general chapter <671> Containers - Performance Testing will become official on May 1, 2018. The USP states, "it is the purpose of this chapter to provide standards for the functional properties of packaging systems used for solid oral dosage forms (SODFs) and liquid oral dosage forms (LODFs)".CS Analytical 38 Industrial West Clifton, New Jersey 07012 888-571-1207
