3. REQUIREMENTS
3.1 Qualification. The barrier materials furnished under this specification shall be products that are authorized by the qualifying activity for listing on the applicable qualified products list before contract award (e
4.2 and 6.4).
3.2 Material. Barrier materials shall be made from such materials and by such process as to ensure compliance with the performance requirements of this specification.
3.3 Construction. Barrier materials shall be constructed of one or more plies in any manner which ensures compliance with the performance requirements of this specification. Butting of component
materials or the finished product shall not be permitted except in the direction perpendicular to the rolling direction. When a butt weld is made on the finished product or any ply thereof, the areas shall be externally flagged with colored markers to prevent u of that portion of the roll.

3.3.1 Splices. A roll shall not contain more than 3 splices (4 pieces) and each piece shall be not less than 45 yards in length. Splices within rolls shall be even the entire width of the roll material and shall not come apart during unwinding of the roll. Rolls containing splices shall be flagged at both ends of each splice with colored markers to indicate splices within the roll. Barrier material in flat cut sheets shall not contain splices (e
港澳通行证过期了怎么办4.3.2.2).
3.4 Form. The barrier material shall be furnished in rolls or flat cut sheets as specified in the contract or order (e 6.2).
3.4.1 Rolls. Unless otherwi specified (e 6.2), the width of roll material shall be 36 inches, with a tolerance of plus ¼ inch or minus 1⁄8 inch. The average length of roll material shall be not less than 200 yards. The length of any individual roll shall be not less than 195 yards. The roll material shall be uniformly wound on nonreturnable cores. The core’s inside diameter shall be not less than 3 inch
es, with a tolerance of plus 1⁄8 inch. The length of the core shall be equal to the width of the roll material, with a tolerance of plus 1⁄8 inch. The core shall be rigid to prevent distortion of the roll during u and shipment conditions (e 4.3.2.3). Each roll shall be restrained to prevent unwinding (e 4.3.2.2).

3.4.2 Sheets. When flat cut sheets are specified, the length and width shall be as specified by the procuring activity (e 6.2). If the length and width tolerances for cut sheets are not specified the tolerance for each shall be plus ¼ inch or minus 1⁄8 inch (e 4.3.2.3). Flat cut sheets shall be uniformly stacked (e 4.3.2.2).
3.5 Sealing. Barrier materials shall be heat-aled under conditions recommended by the manufacturer. The aling conditions shall be such as are considered reasonable for production line aling operations with respect to commonly available aling equipment and commercially practical fabrication time. The material shall exhibit no delamination at the heat-aled area when aled under the manufacturer’s recommended conditions (e
4.5). Each roll or package (flat cuts) of barrier material shall include a tag cured to the core of rolls,
or sheet inrted in the package of sheets with the aling instructions for heat-aling on rotary, band, and jaw-type aling equipment. The tag or sheet shall be visible upon opening the unit package.
3.6 Identification of material. The specification number, class, manufacturer's name, manufacturer's designation, month and year of manufacture, lot number, and heat aling conditions (temperature, pressure, and dwell time) shall be clearly and legibly marked using water-resistant ink on the backing surface of the material. The color of the markings shall be lusterless red (e
4.3.2.1). The complete markings shall be continuous lengthwi and the distance between groups of markings shall be not greater than 2 inches. A complete group of markings shall appear once in each 18 inches of width of the roll. The letters and figures shall be not less than 1⁄8 inch high (e 4.3.2.3).
