When a number of manufacturers produce similar commodities by a variety of techniques, the need for uniform standards is most urgent if the prospective user is to have confidence in any one or all of the materials concerned. If the market for all hardboards is to be developed successfully, standards such as developed and used by the Douglas-Fir Plywood Assoc. must be formulated. First, the important properties must be established based on their relationship to practical application. Then adequate test methods must be created for checking these properties. The standards must be realistic. They are every-day rules of manufacture which are continuously applied in process control, and which finally provide a sound basis upon which users can specify the right product for the right job. Finally, an industry standard should be one which will be met by every panel produced, with a reasonable percentage of falldown allowed for human error.
