Materials and Manufacture3.1 Condoms shall be manufactured from natural rubber latex conforming to Specification D1076.3.2 The condoms and any dressing materials applied to them shall
16、 not liberate substances that are known to be toxic, sensitizing,locally irritating, or otherwise harmful to the general population under normal conditions of use.NOTE 1Natural rubber latex products are known to cause irritation or sensitivity in a small proportion of the user population.NOTE 2Condo
17、m lubricants that contain Nonoxynol 9 spermicide are known to cause irritation in a small proportion of the user population.NOTE 3ISO 10993 contains methods to evaluate the biocompatibility of natural rubber latex condoms.4. Requirements4.1 General:4.1.1 SamplingSamples will be selected randomly fro
18、m the defined “lot.” The sampling plan must conform to therequirements listed in Table 1.4.1.2 Sample HandlingTo avoid inadvertent damage, operators must wear rubber gloves, finger cots, or other suitablehand/finger covers and exercise reasonable caution in handling the packet or condom in order to
19、minimize the possibility ofdamage during the testing procedure.4.1.3 Process ControlsManufacturers may use process control tests to determine condom properties. Finished condoms shallbe used for qualification and referee tests.4.1.4 LotA collection of condoms of the same design, color, shape, size,
20、and formulation manufactured continuously, usingthe same process, raw materials, or the same specification, common equipment, and packaged with the same lubricant and anyother additives or dressing in the same type of individual container. The maximum lot size shall be 500 000 condoms.4.2 Dimensions
21、Condoms shall meet the requirements listed in Table 2.4.2.1 Procedures for Dimensional Test:4.2.1.1 LengthMeasure the length of the condom to the nearest 1 mm, using the method described in Annex A1.4.2.1.2 WidthMeasure to the nearest 0.5 mm the width of the condom laid flat at a distance 30 6 5 mm
22、from the open end.4.2.1.3 ThicknessMeasure the thickness of condoms dried at room temperature for a minimum of 16 h after any dressingmaterials have been removed with water or isopropanol. Measure the wall thickness at three points, 30 6 5 mm, 90 6 5 mm, and150 6 5 mm from the closed end. The thickn
23、ess measuring device shall conform to that specified in Practice D3767, Test MethodAwith the pressure of the foot thickness gage at 22 6 5 kPa. When a condom is textured, measure the thickness in the nontexturedarea. Report the measurements to the nearest 0.01 mm.4.2.1.4 Precision and BiasThis preci
24、sion and bias has been prepared in accordance with Practice D4483. Refer to this practicefor terminology and other statistical details. The precision results in this precision and bias give an estimate of the precision forthis test method. The precision parameters should not be used for acceptance o
25、r rejection of the material, as this data is specificto this round robin and may not be representative of other lots, materials or laboratories. Users of this test method should applythe principles outlined in Practice D4483 to their laboratory and materials or between specific laboratories.The prin
26、ciples of 4.2.1.5would then be valid for such data. Tables 3 and 4 are based on an interlaboratory study conducted in 2001 in accordance withPractice D4483 involving three male latex condom materials (A“thin”, Bregular, C“thicker”), ten laboratories, two locationson the condom (open end150 mm from t
27、he shoulder, closed end30 mm from the shoulder) with two replicates per location takenon the same day. Therefore, p = 10, q = 3, and n = 2. The measurement technique as defined in Practice D3767 was used.4.2.1.5 Concept of r and RIf Sr and SR have been calculated from a large enough body of data for
28、 test results that wereaveraged (medians/other function) form testing X number of specimens, the following definitions are applicable:(a) Repeatability (r)Comparing two test methods for the same material obtained by the same operator using the sameequipment on the same day. The two test results shou
29、ld be judged not equivalent if they differ by more than the r value of thatmaterial.(b) Reproducibility (R)Comparing two test results for the same material obtained by different operators using differentequipment on different days. The two test results should be judged not equivalent if they differ
30、by more than the R value for thatmaterial.(c) Any judgment in accordance with 4.2.1.4 and 4.2.1.5 would have an approximate 95 % (0.95) probability of being correct.There are no recognized standards by which to estimate bias of this test method.TABLE 1 Quality Inspection RequirementsACharacteristic

There are no breaking force, tensile strength, or elongation requirements for condomsgiven in this specification.4.3.1 Procedures for Tensile Propertiesbreaking force, tensile strength, and ultimate elongation. Test methods are presentedin Appendix X1 and Test Methods D412.4.3.1.

Determine tensile properties not less than 16 h or not more than 96
34、 h after heating. Manufacturers may useprocess control tests to determine suitable shelf life, but accelerated aging at 70C for 166 h shall be used for qualification testsand referee tests.4.3.2 Precision and BiasThe precision and bias associated with the tensile strength and ultimate elongation of
35、male condomsare as specified in Test Methods D412.4.4 Air Burst PropertiesCondoms shall conform to the requirements of 4.4.1 for pressure and 4.4.2 for volume.4.4.1 PressureWhen tested as described in Annex A2, the bursting pressure shall not be less than 1.0 kPa.4.4.2 VolumeWhen tested as described
36、 in Annex A2, the bursting volume shall not be less than that as calculated by thefollowing equation:Vmin50.00592w 2! (1)where:Vmin = minimum burst volume in dm3, rounded to the nearest 1 dm3, andw = nominal flat width in millimetres of the shank portion of the condom measured 70 6 5 mm from the ope
37、n end.NOTE 4Cubic decimetre (dm3) is equivalent to litre (L).4.4.3 Precision and Bias:4.4.3.1 Table 5 and Table 6 are based on an interlaboratory study conducted in 1992 in accordance with Practice E691 involvingsix condom lots tested by six laboratories. For each lot, all the samples were prepared
38、at one source but the individual specimenswere prepared at the laboratories that tested them. Each test result was the average of 80 individual determinations. Each labobtained two test results for each condom lot. (WarningThe explanations of r and R in 4.4.3.2 are only intended to present ameaningf
39、ul way of considering the approximate precision of this test method. The data in Table 5 and Table 6 should not berigorously applied to the acceptance or rejection of condom lot, as those data are specific to the round robin and may not berepresentative of other lots, conditions, materials, or labor
40、atories. Users of this test method should apply the principles outlinedin Practice E691 to generate data specific to their laboratory and materials, or between specific laboratories. The principles of4.4.3.2 would then be valid for such data.)4.4.3.2 Concept of r and RIf Sr and SR have been calculat
41、ed from a large enough body of data for test results that wereaverages (medians/other function) from testing X number of specimens, the following definitions are applicable:(a) Repeatability (r)Comparing two test methods for the same material obtained by the same operator using the sameequipment on
42、the same day. The two test results should be judged not equivalent if they differ by more than the r value for thatmaterial.(b) Reproducibility (R)Comparing two test results for the same material obtained by different operators using differentequipment on different days. The two test results should
43、be judged not equivalent if they differ by more than the R value for thatmaterial.(c) Any judgment in accordance with 4.4.3.1 and 4.4.3.2 would have an approximate 95 % (0.95) probability of being correct.4.4.3.3 There are no recognized standards by which to estimate bias of this test method.4.5 Lea
