•Many Medical Device Manufactures are referencing ASTM F as the visual inspection method they use to verify the sterile barrier integrity of their packaging . ASTM F testing provides a qualitative (accept / reject) visual inspection method for evaluating the appearance characteristics of unopened, intact seals in .

In such cases, an additional physical seal integrity test may be required to con?

Last previous edition approved in as F — Insufficient sealing temperature either too much, too little, or unevenly applied pressure; too short a process time; or, excessive material thickness variation are some of the conditions that may cause seals to appear to be spotty or mottled. Size of channel Degree of contrast from sealed and unsealed areas Amount and type of adhesive between the two package layers Reflecting light angle Types of materials used Use of magnification ASTM F procedure is comprised of the following: Completeness and uniformity of the entire seal area of the package must be inspected.

The values given in parentheses are for information only. The width of package seals need to be compared to individually de?

These types of characteristics often are hard to judge by visual inspection alone and need to be further evaluated by alternate means such as dye penetration.

A spotty or mottled appearance may be a function of the adhesive properties, as well. Visual seal characteristics and defects can provide evidence of sterile package integrity and production sealing problems. Seal attributes can be directly linked to a vast amount of variables in process parameters, equipment, or material, as well as environmental room temperature and relative humidity.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations asm to use. Causes to this d1886 include misalignment of package to seal bar or platen, misalignment of the seal bar or platen to the mating seal surface, foreign matter underneath the seal bar or platen xstm a seal, or damage to the seal bar or platen that prevents the seal.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

ASTM-F F18866 Test Method for Determining Integrity of Seals for Medical Packaging by Visual Inspection Seal attributes can be directly linked to a vast amount of variables in process parameters, equipment, or material, as well as environmental room temperature and relative humidity.

NOTE 2—Different package sizes and shapes may require differing lengths of time to adequately inspect the entire seal perimeter. In some situations the seal may be of adequate strength to form a complete seal. Visual seal defects will often be the initial indication of heat sealing process variation. A superscript epsilon e indicates an editorial change atsm the last revision or reapproval.

Any part of the seal where channels appear across entire seal width must be identified and recorded.

ASTM-F – Medical Package Testing

The negative control consists of the same type packages produced with no channels. Generally, this occurs with? Visual seal characteristics and defects can bring forth evidence of sterile package integrity and production sealing problems. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

This may become evident through an evaluation for pinholes or cracks along the seal. The four different types of medical device packages are: The astn characteristics of a package that has never been sealed versus one that has been sealed, and subsequently opened, are very different, and depend on the material substrates being examined.

astmm The ability to visually detect channel defects in package seals is highly reliant on: Seal creep may be a result of the sterilization process or stressed seals at temperature extremes. In some instances, a channel or unsealed area may be observed only after the package is peeled open. A number in parentheses indicates f1886 year of last reapproval.

Wrinkles and cracks occur after a seal is formed and are caused by the asym of the package. Mark the location of the channels. They also will demonstrate a lack of, or potential compromise to, package integrity after physical package performance testing.

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

This is because the coating may have a stronger affinity for the substrate on which it is coated rather than the one to which it is sealed. Viewing the seal area in a UV light box will enhance the sealed-to-unsealed area contrast, and provide for easier defect identi?

ASTM F1886/F1886M – 16

Heat seals should be cooled to ambient conditions before peeling open to allow for adhesive bonding to the opposite substrate to occur. In other situations there may not be adequate strength, and a channel results. They also will indicate a lack of, or potential compromise to, package integrity after physical package performance testing.
