1. Rationale
Item 1 was suggested at the December 2006 meeting in Atlanta to include a longitudinal joint in materials provided in plank or strip form. The proposal was made from a laboratory involved in testing laminate flooring materials who found that a product burned readily along a longitudinal joint but did not burn if the plank surface with no joint was tested. At the June 2007 meeting in Norfolk, task group E05.22.05 decided to limit the width of materials where testing with a longitudinal joint is required.
Item 2 is a proposal to remove Figure 1 from the standard. Figure 1 is a photograph (circa mid-1970Ęs) of the test apparatus and no longer represents the appearance of test equipment currently manufactured. No line drawing is available to replace the photograph. At the June 2007 meeting, it was proposed the photograph be moved to an Appendix with Figure 1 identified as a Historical Photograph.
Item 3 is a revision requested at the June 2007 meeting by a flooring manufacturer to include sample preparation instructions for laminate flooring products. In the laminate industry there are two basic ways of attaching laminate boards, one is a tongue and groove with a pre-glued groove that is activated by water, and the other is the click method. Specific means of sealing seams are not included, nor is the traditional laminate flooring thickness of 6 to 10 mm mentioned.
