Hordwood Plywood Industry RevisesCommerciol Stqndnrd C535

The Technical Committee of the Hardwood Plywood Institute has revised the Commercial Standard for hardwood plywood for the first time since 1956. The new standard applies to all hardwood produced as of March 31, 1961.

Commercial Standards are not set up by the government, but are written by interested groups, with the U.S. Department of Commerce, Commodity Standards Division acting as the clearing house and moderator for these groups. After these groups have agreed on its terms, the standard is distributed by the Department of Commerce, but enforced by the Industry.

It was through the Plywood Manufacturers Association, the predecessor of the HPI, in 1931, that the industry took its first steps toward a Commercial Standard for hardwood plywood. After acceptance by the distributors and users, it was promulgated as CS35-31. The "3l" stands for the year of promulgation.

Thenew Standard is designated as CS35-61. Special reprints carrying facsimiles of HPI Labels are available free from the Hardwood Plywood Institute, P.O. Box 6246, Arlington 6, Virginia in single copies. In quantity the folder with CS35 sells for 25c. The Hardwood Plywood Institute is the national trade association of hardwood plywood manufacturers with 57 members 1ocated in 15 states from coast to coast. The Institute's office and laboratory is located in Arlington, Virginia. The folder includes the following information not contained in CS3561: 1. Four simple steps to install and finish hardwood plyryood. 2. Information on Strength-Weight Ratios, flexural strength properties, and bending properties of hardwood plywood. 3. Check list for specification writers.4. Illustrations of types of veneer arts and veneer figure types. 3. Illustrations of veneer matching including vertical butt and horizontal bookleaf, book, slip, random, diamond, reverse diamond, "V" herringbone, and four-way center and butt. 6. Facsimiles of HPI's Certificates and Labels.

Grades

Grade descriptions of all species have been changed to more nearly conform to grade descriptions of the hardwood veneer and flush door industries. New grades are

Premium (l); Good (l); Sound (2); Utility (3); Backing (4), and Specialty (SP). The difference between Premium (1) and Good (1) is that in Premium grade when the face consists of more than one piece, it must be matched for color; in Good (1) grade the pieces need not be matched, but sharp contrast is not permitted.

The new Specialty grade inciudes plywood that does not conform to any of the other five grades such as architectural plywood, matched grain panels for special uses and special veneer selections. Both user and maker should agree in description and characteristics of the Specialty grade.

Siandard Sizes

Under standard sizes and thicknesses, 16" and 32" widths have been added and 30" and 4U' widths have been deleted. Under lengths 120" lengths have been added.

New Core Materiat

For the first time, particle board and wood composition board and softwoods have been written into CS35-61 as a core material for hardwood plywood. Softwood plies must conform with their applicable plywood standard ocToBER t, 196l

CS45-60-Douglas Fir plywood; CSL2L60Western Softwood plywood; or CS157-56Pine plywood.

HPI IABEI.ING AND CERTIFICATION

The Hardwood Plywood Institute owns and licenses their labels and has the right to permit their use only if the quality of the hardwood plywood is up to high HPI requirements.

folds face paper under the screwhead, and minimizes cutting. Added corrosion resistance is supplied by the cadmium coating.

Although outstanding results have been achieved with the original U.S.G. drywall screw, research and extensive field experiences have enabled the company to further improve the design of its exclusive product.

N.H.t.C.

The familiar initials H.LC. will become N.H.I.C. as a result of action taken by the Board of Dircetors of the Home Improvement Council at its July meeting.

On recommendation of the Council's new chairman, Carroll O'Rourke of the Weyerhaeuser Company, the "National" was added toits officibl name. O'Rourke emphasized that the name "National Home Improvement Council" more efiectively suggests the Council's role as "the only truly national and industry-wide voice for the home improvement business."

In addition, the Board approved a new schedule of membership fees and plans for an intensive drive to broaden membership support. Under the new rates, the top fee for a national manufacturer's annual membership is $1,000. Fee for a typical dealer or contractor is $25.

Five leading manufacturers, among others, have renewed their N.H.I.C. membership to get the membership drive underway, O'Rourke revealed. They are: Georgia-Paci- fic Corp., Masonite Corp., Owens-Corning Fiberglas, United States Plywood Company and the Weyerhaeuser Company.

Other actions of the Board included reelection of James M. Lange, executive editor of Practical Builder magazine as a member of the Board, and the decision to seat presidents of all local N.H.I.C. chapters as national directors.

The HPI stamps may be withdralyn if a manufacturer fails to meet these requirements. The Institute has a strict policy for qualifying manufacturers for their use by plant inspection and sampling. HPI's plant inspector visits the manufacturing plant at any hour of the day or night unannounced. During his visit, the inspector carefully checks each manufacturing step and makes a report to the mill and to the HPI laboratory. The Institute's inspector sends the random plywood samples he has selected in the mill and in the warehouse to the HPI laboratory in Arlington, Virginia, for speedy glueline testing. Results are returned to the plant.

In order to assure the purchaser that he is getting hardwood plywood of the quality specified in CS35-61, producers may, in concert with HPI. issue certificates for each shipment or label each piece of plywood as conforming to CS35-61.

The HPI is your guarantee that the plywood is bonded as specified in the commercial standard 35-61. Look for this HPI Seal on your plywood panels. It is your assurance of dependable quality glueline.

A vastly improved drywall wood screw is now available from United States Gypsum Company. The new ll-in. U.S.G. Drywall Screw Type "W" features a diamond point, double-lead thread, contoured head, and cadmium coating. There is no price increase for this new screw.

The new diamond-pointed fastener, {-in. longer than the former screw, offers greater holding power. The diamond .point penetrates manila face paper with only moderate pressure on the screw gun, and eliminates "wobble" upon entry. Double-lead threads give easier, quicker penetration with greater holding power. The contoured head gently

For Fire Proteclion, Reod This

A completely revised edition of the NFPA standard dealing with fire safe practices for retail and wholesale lumber storage yard has just been issued by the National Fire Protection Association.

The safe practices recommended in this standard (NFPA No. 47) apply to: (a) retail lumber yards handling forest products and other building materials; (b) wholesale lumber storage yards including distribution, holding and trans-shipment areas; and (c) buildings in the above yards used for storage of forest products including buildings used for auxiliary operations.

The complete rewrite of this standard was done by the NFPA Sectional Committee on Storage of Forest Products chairmanned by W. G. Schultz of the Lumbermens Mutual Insurance Company, and was adopted at the recent annual meeting of the National Fire Protection Association.

Also adopted at the Association's annual meeting was partof another standard prepared by this committee. "Recommended Safe Practices for Outdoor Storage of Forest Products" (NFPA No. 46) is in two parts.

Part I-"Outdoor Storage of Lumber and Timber at Other than Retail or Wholesale Yards"-was adopted by the NFPA in 1960.

Joints Reploce Blocking on Roof, Woll Sheothing

Tongue and grooved joints that can eliminate blocking for edge support of plywood roof and wall sheathing have been developed by the Douglas Fir Plywood Association and will soon be "pp..rirrg on panels marketed by association members. A laboratory report giving performance details is available free from Te-chnical Department, Douglas Fir plywood Association, Tacoma 2. Wash.

The joints were developed in response to wide acceptance to a similar one perfected f.or 2.4.1., the l%-inch thick combination sub- floor and underlayment panel. The 2.4.1. joint eliminates the need for cross-blocking in floor installations and reduces framing require- ments to girders 4 feet on center. Similar refinements in wali and roof construction are expected with the new joints on fu-inch, ft-inch and fi-inch panels.
