The moisture permeability of polyvinyl chloride, cyclic olefin copolymer, Aclar and cold-form aluminum blisters by the USP24/NF Containers-Permeation test is shown in Table 2. The four blister materials have very different moisture permeability properties.
integrity. Package moisture permeation is a critical quality attribute for solid oral dosage forms, with moisture uptake being a common cause for product package failures. Current permeation methods in USP–NF General Chapter <671> Containers— Performance Testing establish equivalence for packaging (cap/bottle and blister packs) Introduction: Moisture permeability and a loose closure system might allow a significant gain of moisture into container and this could lead to significant loss of potency of drug sensitive to .The 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 .•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 final

One of the main functions of the workshop will be to discuss proposed new revisions to General Chapter <671> Containers—Performance Testing that will be included in Pharmacopeial Forum 39(2 ) March-April 2013. . The new method will include guidelines for testing the moisture vapor transmission rate (MVTR) for multiple-dose containers, such . Water vapour permeability test: Fill five containers with nominal volume of water and heat seal the bottles with an aluminum foil-poly ethylene laminate or other suitable seal. Weigh accurately each container and allow to stand (without any overwrap) for 14 days at a relative humidity of 60+5% and a temperature between 20 and 25 0C Reweigh the .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 .
Polyethylene Container— Fit the containers with impervious seals obtained by heat-sealing the bottles with an aluminum foil–polyethylene laminate or other suitable seal. 2 Test the containers as specified under Multiple-Unit Containers for Capsules and Tablets: the high–density polyethylene containers so tested meet the requirements if the moisture permeability .
The water vapour permeability of the fabric is the loss in weight of water in the cup, expressed in g/m2/day. Since the water vapour permeability is influenced by the still air layer resistance below the fabric, which dominates the total resistance and .Principles apply to containers for API, bulk, intermediates. Packaged headspace. Air or nonreactive gases. At specified water vapor content. At ambient or sub-ambient pressures. Package (aka Container-closure): Primary package components. In direct product contact (or may be) Secondary package components critical for ensuring package assembly . E.g
Water vapor permeability is a measure of the passage of water vapor through a material. It is also known as water vapor transmission rate (WVTR) or moisture vapor transmission rate (MVTR) - which is basically the mass of water vapor that is transmitted through a measured area in a specific unit of time under specified conditions of temperature and humidity.4.2 Supply of De-aired Water - An adequate supply of clean de-aired water shall be available for use in the permeability tests. Water may be easily de-aired for this purpose by boiling and cooling. De-aired water may be stored in closed containers, which should, as . This paper focuses on the various methods to test moisture permeability and the analysis of the influencing factors of test results. Currently, outdoor sports are relatively active, and the outdoor clothing needed will be . Acquiring an accurate measurement of water vapor permeability through porous materials, such as paper, plastic films, fiberboards, gypsum, plaster products, wood products, and plastics, is essential for compiling a .
The permeability test is a measure of the rate of the flow of water through soil. In this test, water is forced by a known constant pressure through a soil specimen of known dimensions and the rate of flow is determined. This test is used primarily to. determine the suitability of sands and gravels for drainage purposes, and is made only on . General Chapter <671> Containers – Permeation. Water Vapor Transmission Rate (WVTR) testing was performed to construct weight gain profiles due to moisture ingress . 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• Insert positive pressure source with monitor into test sample • Submerge test sample in water; apply air to target pressure; hold for pre-determined time • Observe for continuous stream of bubbles. Test (External Vacuum): ASTM D3078 • Submerge test sample in water or other suitable fluid in vacuum chamber At present, the commonly used container moisture permeability test method is developed on the basis of the membrane moisture permeability test weighing method. The principle of weighing method is adopted, and the relevant test standards are GB/T 6981-1986, GB/T 6982-1986, ASTM D 3079-94. According to the nature of the material, it is divided .

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 of the containers exceeding moisture permeability of 100 mg/day/L whereas containers from supplier C had an average of 149.95 mg/day/L with seven of . Each industry has its own set of regulations mandating moisture content testing. For instance, in agriculture, water testing is required during different stages of production handling. In construction, the ASTM F-2170 standard is utilized for moisture checking on concrete floors. Manufacturers must follow standard methods for moisture testing.Results and Discussion It can be seen in the results indicated in Figure 1, containers supplied by supplier C were incorrectly regarded as “Tight containers” as their average rate of moisture permeability was not within the range specified in the USP 37 <671> whereas containers supplied by supplier A and B were correctly regarded as .At present, the commonly used container moisture permeability test method is developed on the basis of the film moisture permeability test weighing method. It adopts the weighing method test principle. The relevant test standards are GB/T 6981-1986, GB/T 6982-1986, According to ASTM D 3079-94, according to the nature of the material, it is .
