However, the results of this test may be used as elements of a fire risk assessment, which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.<\/p>\n<p>5.3.1 The classification of the faced insulation shall be no greater than a flame spread index of 25 and a smoke-developed index of 50 when tested on the facing side.<\/p>\n<p>5.4 Fungi Resistance\u2014The adhesive (used to affix the vapor retard\/facing to the fiberglass) shall be certified by the adhesive supplier as tested separately per ASTM C1338 and shall exhibit no growth.<\/p>\n<p>5.5 Integrity\u2014Laminated insulation shall not exhibit obvious oxidation\/corrosion, discoloration, or delamination of facing, nor exhibit a lack of adhesion of facing to insulation when inspected visually.<\/p>\n<p>5.6 Dimensional Tolerances\u2014The average measured length and width shall not differ from the manufacturer\u2019s standard dimensions when determined in accordance with paragraph 8.1, by more than the following:<\/p>\n<p style=\"padding-left: 40px;\">Length, -0, +1\/2 inch<\/p>\n<p style=\"padding-left: 40px;\">Width, +\/- 1\/4 inch<\/p>\n<p>Normally, a slight excess in all dimensions will be permitted.\u00a0 However, the purchaser may elect to specify a maximum tolerance to meet further processing requirements.<\/p>\n<hr \/>\n<h3><strong>6.0 Workmanship<\/strong><\/h3>\n<p>6.1 The material shall indicate good workmanship and shall not have visible defects which adversely affect its serviceability. Vapor retarders or facings should not be torn or punctured. Tears and or punctures in the vapor retarder or facing shall be repaired or replaced.<\/p>\n<hr \/>\n<h3><strong>7.0 Sampling and Inspection<\/strong><\/h3>\n<p>7.1 The laminator\u2019s normal sampling and inspection procedures shall be acceptable as outlined in Section No. 4 of ASTM C390, unless agreed otherwise.<\/p>\n<hr \/>\n<h3><strong>8.0 Test Methods<\/strong><\/h3>\n<p>8.1 Thickness Measurement<\/p>\n<p>8.1.1 Sample Preparation\u2014A representative roll of insulation, at least 25 feet in length, is rolled on a flat surface. When roll lengths are in excess of 75 feet, it is permissible to cut the roll into two equal lengths for ease of handling. The test roll is then flipped over for its entire length. Finally, after grasping one end, the material is pulled back over itself until the original surface is again facing up and allowed to rest for 15 minutes.<\/p>\n<p>8.1.2 Test Procedure\u2014Five thickness measurements are then taken, using a pin and disc gauge per ASTM C167 on each third of the roll starting five feet in from the roll ends. The five thickness checks should be spaced uniformly over each third of the roll, sampling the full width but not closer than 1\/10 of the width from the edges.<\/p>\n<p>8.1.3 Calculation and report\u2014Calculate the average of 15 thickness recovery checks from the roll. The average thickness recovery value can be used to calculate the thermal resistance in 5.1, providing the thermal conductivity of the material is known or has been supplied by the manufacturer.<\/p>\n<p>8.2 Length and Width Measurement<\/p>\n<p>8.2.1 Sample Preparation\u2014A representative roll of insulation is completely unrolled on a flat surface.<\/p>\n<p>8.2.2 Test Procedure\u2014A steel measuring tape of sufficient length shall be used to measure the entire length and width of the fiberglass insulation roll. An alternate method may be used where the flat surface has been previously ruled out to facilitate ease of measurement.<\/p>\n<p>8.2.3 Calculation and Report\u2014Determine the length and width in several locations and record the average values.<\/p>\n<hr \/>\n<h3><strong>9.0 Inspection<\/strong><\/h3>\n<p>9.1 Inspection of the laminated material should be agreed upon by the purchaser and the supplier\/laminator as part of the purchase contract.<\/p>\n<hr \/>\n<h3><strong>10.0 Rejection<\/strong><\/h3>\n<p>10.1 The process for rejection, as set out in the remainder of section 10, states the laminated material should be agreed upon by the purchaser and the supplier\/laminator as part of the purchase contract.<\/p>\n<p>10.2 If inspection of the sample shows a failure to conform to the requirements of this specification, a second sample from the same lot shall be tested, and the results of this secondary averaged with the results of the original test.<\/p>\n<p>10.3 Upon the results as described in 10.1, if the product fails to conform to this specification, the results shall constitute grounds for rejection of the lot of the same lamination date printed on or in the packaging of the tested rolls.<\/p>\n<p>10.4 In case of rejection, the laminator or seller shall have the right to inspect the rejected shipment or resubmit the lot after the removal of that portion of the shipment not conforming to the specified requirements.<\/p>\n<hr \/>\n<h3><strong>11.0 Product Certification<\/strong><\/h3>\n<p>11.1 Thermal Certification\u2014Samples of this product are tested and\/or verified periodically, at least once per year by a nationally recognized independent, third-party laboratory and determined to meet the stated dimensions and thermal resistance in accordance with this Certified Faced Insulation Standard. The laminator shall represent that the product being presented for testing has been produced to the standard.<\/p>\n<p>11.2 Surface Burning Characteristics Certification\u2014Samples of this product, selected randomly, are to be tested and\/or verified periodically, at least once per year by a nationally recognized independent, third-party laboratory and determined if they meet the stated flame-spread-and smoke-developed index values in accordance with this Certified Faced Insulation Standard.<\/p>\n<hr \/>\n<h3><strong>12.0 Product Marking<\/strong><\/h3>\n<p>12.1 Unless otherwise specified, the seller\u2019s name and designation, length, width, thickness, R-value, the total number of square feet, manufacturing date code, surface burning characteristics, and type of facing shall be noted on the package label.<\/p>\n<p>12.2 The package shall also be marked with the label(s) of the appropriate certifying laboratory for thermal certification and surface burning characteristics.<\/p>\n<hr \/>\n<h3><strong>13.0 Packaging of Faced Fiberglass<\/strong><\/h3>\n<p>13.1 Unless otherwise agreed or specified between the purchaser and the laminator or the purchaser and the seller, the insulation shall be packed in a\u00a0\u00a0 standard commercial container.<\/p>\n<p>13.2 If there is residual moisture in the product at the time of packaging, the package shall be suitably vented to allow for evaporation of the moisture.<\/p>\n<hr \/>\n<h3><strong>14.0 Storage<\/strong><\/h3>\n<p>14.1 The material shall be stored in such a manner as to protect the package from direct sunlight, weather, temperature extremes, and extreme compression.<\/p>\n<p>14.2 Shelf life shall be agreed upon between the laminator\/seller and the purchaser.<\/p>\n<hr \/>\n<h3><strong>15.0 Moisture<\/strong><\/h3>\n<p>15.1 Long service life and optimum performance characteristics of fiberglass insulations are predicated on the requirements that dry insulation is applied to clean and dry surfaces, and that they are protected against the incursion of water during installation and by adequate design and maintenance after installation.<\/p>\n<p>15.2 Wet insulation provides depreciated thermal performance in comparison to dry insulation; once installed, it is difficult to dry insulation completely. The incursion of water may also introduce compounds and organisms which may accelerate the corrosion of metals and may permit mold or mildew growth and odors.<\/p>\n<p>15.3 Tests conducted under laboratory conditions on relatively small specimens of fiberglass artificially wetted with distilled water in the liquid phase and thoroughly dried under conditions free of shear or compressive forces indicate no adverse effect on the apparent thermal conductivity. This would suggest that insulation wetted in service could regain most of its thermal resistance, provided it could be dried without a significant loss of thickness. However, there is no assurance that the drying method used or the forces acting on the wet insulation will not result in loss of thickness or that contaminants in the water may not contribute to corrosion, mold or mildew growth, or odors.<\/p>\n<hr \/>\n<p><em>Disclaimer: The National Insulation Association (NIA), its members, and\/or its agents, make no guarantee as to, and assume no responsibility for, the correctness, sufficiency, or completeness of the information contained herein.
