1、Designation: F 1516 08Standard Practice forSealing Seams of Resilient Flooring Products by the HeatWeld Method (when Recommended)1This standard is issued under the fixed designation F 1516; the number immediately following the designation indicates the year oforiginal adoption or, in the case of rev
2、ision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers the instructions and precautions tobe observed to ensure satisfactory performa
3、nce of seams inresilient flooring sealed by the heat weld method.1.2 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the appl
4、ica-bility of regulatory limitations prior to use. See precautioninformation in 6.1.2. Referenced Documents2.1 ASTM Standards:2F 141 Terminology Relating to Resilient Floor Coverings3. Terminology3.1 For definitions of terms used in this practice refer toTerminology F 141.4. Significance and Use4.1
5、Seams in some resilient flooring are heat sealed toprevent openings from forming between cut edges and toprevent penetrations of dirt, liquids, etc., into the seams.Decorative appearances may also be achieved using contrast-ing heat weld thread (rod).5. Instructions5.1 Flooring shall be installed in
6、 accordance with themanufacturers instructions.5.2 Particular attention shall be paid to proper cutting ofseams and tightness of cut seams. Specified tightness of seamsto be heat sealed (welded) will vary depending on the flooringproduct and type of tools used to perform the heat weld.5.3 Prior to h
7、eat welding, seams shall be routed to a depthspecified by the manufacturer. Routing can be accomplishedwith electric or hand routing tools as specified by the manu-facturer. Follow flooring manufacturers instructions for spe-cific details.5.4 Unless specified otherwise by the resilient manufacturer,
8、wait 24 h before routing and heat welding the seams. Thisallows time for the adhesive to set. Heat welding must becompleted before beginning initial flooring maintenance. Sometile products are routed at the factory, and on site routing is notrequired. Heat welding involves the melting of thread (rod
9、)into the gap of a routed seam. Special electric hot air tools withvariable temperature settings are required. Because tempera-ture settings will vary, depending on the length of extensioncord, room and under floor temperature, floor covering mate-rial, welding rod composition, etc, test welding is
10、recom-mended. Verify the correct thread color, then using excess orscrap material, make test welds as needed to establish heatwelding conditions. Next, do a trial length seam and evaluateafter cooling to determine if the bond strength and appearanceof the weld thread to the seam edges are satisfacto
11、ry. Weldthreads are available in a variety of plain, solid colors andpatterned versions. The color or pattern of the thread can beselected to either match with the flooring color to hide ordisguise the seam or contrast with the flooring color to accentthe seam.5.5 Approximately one-half of the weld
12、thread thicknesswill adhere to the seam. The excess will be trimmed off flushwith the surface of the flooring when cooled. Trimming ofexcess weld thread is accomplished using a one- or two-stepprocess depending upon product type; one for most rubberproducts and in two steps for vinyl and linoleum pr

16、 steps 5.3 to 5.5. When finished repair,make sure the seamed area is spot maintained to blendappearance to surrounding flooring for appearance, color andgloss.6. Precautions6.1 Use caution when handling and using tools required forheat welding seams. Hot air guns can cause severe burns.Routing tools
17、 and trim knives are very sharp. Be sure electricextension cords are in good condition and connected to aground fault receptacle.6.2 Heat welding is a function of temperature and speed.Welding too cold will not give good bonding. Welding too hotcan distort the flooring product surface adjoining the
