Report the measurements to the nearest 0.01mm.5.4.2 Precision and bias for measuring the thickness can befound in Specification D3492.5.5 Leakage:5.5.1 CriteriaPolyurethane c

27、ondoms that burst during thetest or show any evidence of leakage in the test area, includingseepage, micro-droplets, squirters, and so forth, not includingleakage at a distance of 25 mm (1 in.) or less from the openend, will be considered failures. The test method is described inAnnex A5 with the qu

28、ality inspection level and AQL given inTable 1.5.5.2 Precision and BiasNo statement is made concerningthe precision or bias of determining leakage in condoms sincethe result states merely whether there is conformance to thecriteria specified.5.6 Strength Requirements for Polyurethane Condoms:5.6.1 T

29、he strength of the condom can be determined usingeither ring or dumbbell test pieces. If the condom is manufac-tured with a welded seam, then it is required that the weld ofthe condom be in the test area.5.6.2 Procedure for Tensile Properties: Breaking Force,Tensile Strength, and Ultimate Elongation

35、 condom shall have an ultimate elon-gation of greater than 675 %.5.6.7.2 Type BThis condom shall have an ultimate elon-gation of no more than 675 % and no less than 400 %.5.6.7.3 Type CThis condom shall have an ultimate elon-gation of less than 400 %.5.6.8 The tensile strength specifications in Tabl

36、e 1 for TypesA, B, and C can then be utilized without the need forcompletion of a material validation protocol but only for thatproductdefined by the specific shape, thickness and lubricantsystem. A slippage and breakage user study could be necessaryto achieve local regulatory approval.5.7 Packaging

37、:5.7.1 Unless otherwise specified, packaging shall be inaccordance with the manufacturers commercial practice.5.7.2 Packaging shall be tested in accordance with TestMethod D3078 with the pressure reduced to 50 kPa (380 mmHg or 15 in. Hg) below atmospheric pressure. The inspectionlevel and AQL are gi

38、ven in Table 1.5.8 Design RequirementsWhile the rapid proliferation ofnew materials and development in polyurethane condomsmake standardization difficult, the design tests included in thisstandard shall be used as a guide in the development orassessment, or both, of polyurethane condoms. Rather than

39、describe a list of requirements and tests that might be soonoutdated, Annex A9 consists of what is required to validate thedesign of polyurethane condoms.5.9 Air Burst PropertiesThis part of the standard specifiesa test method for determining the volume and pressure at breakfor polyurethane condoms.

40、 The specifications for the airbursttesting of volume and pressure will be derived from thematerial validation exercise in Section 8 and Annex A9.5.9.1 Procedures for Air Burst Properties: Volume andPressureA test method is presented in Annex A7.5.9.2 Precision and bias for the air burst testing can

Labeling6.1 Each condom package (individual primary package andretail package) shall be legibly marked.6.1.1 The name or trademark of the product shall beincluded on each condom package (individual primary packageand retail package).6.2 The expiration date, which s

42、hall be marked as such, forexample, “Exp.,” shall be displayed on the condom primarypackage (a.k.a. “wrapper” or “foil”) and the retail package.6.2.1 The expiration date, which shall be interpreted as thelast day of the month indicated, shall be displayed as the monthand year of expiry using either

43、a numeric or alphabetic month,preceded or followed by the numeric year designation, forexample: 01/2010 or Jan 2010 or 2010/01 or 2010 Jan.6.2.2 The expiration date shall be determined as specified inAnnex A8.6.3 Each condom primary package and retail package shallalso include the name and place of

44、business of manufacturer,packer or distributor; statement of identity (“polyurethanecondom”); lot number and expiration date; the intended uses;appropriate warning statements; and declaration of net quantityof contents.6.4 The retail package label shall, if appropriate, indicatethe country of origin

45、 (for example, “Made in -”) and mayalso contain information regarding the description of thecondom (for example, nominal width, length, texture, shape,etc.).6.5 Appropriate directions for use shall be included on theretail package or separately in a package insert.6.6 For packaged condoms intended f

Storage7.1 During production, processing, and packaging, condomsshall not be allowed t

47、o come into contact with materials thatwill degrade the condom.7.2 In-process bulk unpackaged condoms should be storedin appropriate closed containers in dry areas at a temperaturebelow 40C (104F). Storage for short periods of time abovethis temperature will not be harmful to product. They should be

48、kept away from direct sources of heat and ultraviolet light.8. Condom Material and Clinical Validation8.1 The manufacturing process used to make the condomlots will have completed a documented validation process.8.2 Full production lots will be sampled to complete thecondom material validation.8.3 A

49、 material characterization protocol shall be under-taken. Examples of useful testing techniques are outlined inAnnex A9, Note A9.1. Airburst testing and tensile strengthtesting shall be the minimum physical testing required.8.4 Once the validated process used for the manufacture ofthe condom has been determined to be in control, i.e. produc-ing condoms with stable and predictable physical properties,three production lots should be sampled using statistically validsample sizes to produce a baseline distribution of the airburstand tensile strengt
