ASTM F1886 PDF

Insufficient sealing temperature either too much, too little, or unevenly applied pressure; too short a process time; or, excessive material thickness asym are some of the conditions that may cause seals to appear to be spotty or mottled. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Impact also may cause the seals to partially rupture. 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. The four different types of medical device packages are: It is possible to have continuous seal integrity but fail to give complete transfer.

Dakree The r are presented in Tables The ability to visually detect channel defects in package seals is highly reliant on: Last previous edition approved in as F — Seal attributes can be directly linked to a vast amount of variables in process parameters, equipment, or material, as well as environmental room qstm and relative humidity. Further evaluation may be required if visual inspection is not adequate to determine acceptability.

Light box inspection or physical package integrity tests may be appropriate. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. A spotty or mottled appearance may be a function of the adhesive properties, as well. They also will indicate a lack of, or potential compromise to, package integrity after physical package performance testing. These types of characteristics often are hard to judge by visual inspection alone and need to f further evaluated by alternate means such as dye penetration.

Your comments are invited f for revision of this standard or f additional standards and should be addressed to ASTM International Headquarters.

Wrinkles and cracks occur after a seal is formed and are caused by the handling of the package. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. ASTM F is pertinent to flexible and rigid packages with at least one transparent side so that the seal area may be clearly viewed. In some instances, a ff or unsealed area may be observed only after the package is peeled open. Visual seal characteristics and defects can provide evidence of sterile package integrity and production sealing problems.

In such cases, an additional physical seal integrity test may be required to con? Viewing the seal area in a UV light box will enhance the sealed-to-unsealed area contrast, and provide for easier defect identi? NOTE 2—Different package sizes and shapes may require differing lengths of time to adequately inspect the entire seal satm. Seal rupture can occur due to internal or external forces placed on the seal due to sterilization conditions, weight of product, stressful handling of the package, and so forth.

Care should be taken to ensure a smooth continuous peeling motion so as not to cause any xstm attributes. The visual 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.

The width of package seals need to be compared to individually de? They also will demonstrate a lack of, or potential compromise to, package integrity after physical package performance testing. It is possible to have adtm seal integrity but fail to give complete transfer.

Seal creep may be a result of the sterilization process or stressed seals at temperature extremes. Record the number and location of channels identified on each package. Any time requirement associated with visual inspection should allow for complete seal inspection without taking too much time to intensely focus on any given area. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

There also can be foreign contamination on the packaging materials that prevents a seal from being made. Originally approved in These too can result in a channel through the entire seal. For more information visit www. Each requirement should be established with appropriate rationale and necessary supporting documentation. Causes to this problem 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 preventing a seal, or damage to the seal bar or platen that prevents the seal.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. ASTM-F — Medical Package Testing 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.

ASTM-F Standard Test Method for Determining Integrity of Seals for Medical Packaging by Visual Inspection Seal asgm 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. In other situations there may not be adequate strength, and a channel results. Often it is easier to see this type of defect under a magnifying light or UV light box. Inspection of the seal should be performed at a distance of aztm to 45 cm 12 to 18 in.

A number in parentheses indicates the year of last reapproval. It is the responsibility of the user of this standard to establish appropriate r and health practices and determine the applicability of regulatory limitations prior to use. The negative control consists of the same type packages produced with no channels. TOP Related Articles.

Visual seal characteristics and defects can bring forth evidence of sterile package integrity and production sealing problems. Visual seal defects will often be the initial indication of heat sealing process variation. They also will demonstrate a lack of, or potential compromise to, package integrity after physical package performance testing. The ability to visually detect channel defects in package seals is highly reliant on: Size of channel Degree of contrast from sealed and unsealed areas Amount and type of adhesive between the two package layers Reflecting light angle Use of magnification ASTM F procedure is comprised of the following: ASTM F is pertinent to flexible and rigid packages with at least one transparent side so that the seal area may be clearly viewed. Inspection of the seal should be performed at a distance of 30 to 45 cm 12 to 18 in. Completeness and uniformity of the entire seal area of the package must be inspected.
