Venetian blinds, a commodity of increasing popularity, lendthemselves to certain substitutions in quality that are readily concealed and become manifest only after a period of service.In orderto promote a better understanding between buyers and sellers and toprovide a basis for labeling as advance assurance of accepted construction and workmanship, this commercial standard is recommendedas a guide for all concerned.SCOPE2. This commercial standard covers Venetian blinds of the freehanging, tilt-rail type for residence and office use in three widths ofslats, 1%, 2, and 2% in., respectively, with slats adjustable to variousangles and with raising, lowering, and tilting actions controlled bycords, chains, or cables.(Seefig. 1.)RAIL CENTER SUPPORT(USED WITH 3 OR MORE TAPES).A.- TILTFigure1.—Pulley operated blind showing various operatingparts.GENERAL REQUIREMENTS3.

Venetian blinds made according to this commercial standard areequipped with tape and cord dyed in the yarn to obtain comparativelynonfading colors. However, under the very severe circumstances ofexposure, it is impracticable to guarantee tapes and cords againstfading.Certain colors are more permanent than others and helpfulassistance in their selection is available from experienced distributors.

C.HISTORY OF PROJECTDueto the popularity of Venetian blinds and the growing tendencycheapen their construction, the National Venetian Blind Guild,under date of January 18, 1937, requested the cooperation of theNational Bureau of Standards to assist in setting up a commercialstandard of quality for wood-slat Venetian blinds.The specifications committee of the guild drafted a proposedstandard which was circulated to all known manufacturers, manyprominent distributors, and a number of consumer groups, togetherwith an invitation to attend a general conference under the auspicesof the National Bureau of Standards to discuss the proposed standard.The conference, held in Chicago, 111., on March 15, 1937, was verywell attended and a number of modifications were made in the standard as proposed. The conference voted to recommend the standardin its modified form for general acceptance by the entire industry.It was sent from the National Bureau of Standards on April 2, 1937,,together with an acceptance form by which those interested couldrecord their intention to follow the standard as far as practicable.A satisfactory majority of the production volume of the wood-slattovenetian-blind industry indicated acceptance of the recommendedcommercial standard and the success of the project was announcedJuly 1, 1937. The standard became effective for new production onSeptember1,1937.

C.Gentlemen:Having considered the statements on the reverse side of this sheet,we accept the Commercial Standard CS61-37 as our standard ofpractice in theProduction1DistributionUse11of wood-slat Venetian blinds.will assist in securing its general recognition and use, and willcooperate with the standing committee to effect revisions of theWestandardwhennecessary.Signature(Kindly typewrite or print the folowingName andlines)titleCompany(Fill in exactly asitshould be listed in pamphlet)Street addressCity and State1Please designate which group you represent by drawing lines through the other two. Please file separate acceptances for all subsidiary companies and affiliates which should be listed separately as acceptors.In the case of related interests, trade papers, colleges, etc., desiring to record their general approval, thewords “in principle” should be added after the signature.7

TO THE ACCEPTORThe following statements answer the usual questions arising inconnection with the acceptance and its significance:1. Enforcement.Commercial standards are commodity specifications voluntarily established by mutual consent of the industry.Theypresent a common basis of understanding between the producer, distributor, and consumer and should not be confused with any plan of—governmental regulation or control. The United States Departmentof Commerce has no regulatory power in the enforcement of theirprovisions, but since they represent the will of the industry as awhole, their provisions through usage soon become established astrade customs, and are made effective through incorporation intosales contracts by means of labels, invoices, and the like.2. The acceptor’s responsibility.The purpose of commercial stand-—ards is to establish for specific commodities, nationally recognizedgrades or consumer criteria and the benefits therefrom will be measurable in direct proportion to their general recognition and actual use.Instances will occur when it may be necessary to deviate from thestandard and the signing of an acceptance does not preclude suchdepartures; however, such signature indicates an intention to followthe commercial standard where practicable, in the production, distribution, or consumption of the article in question.The major function performed3. The Department’s responsibility.by the Department of Commerce in the voluntary establishment ofcommercial standards on a Nation-wide basis is fourfold: first, toact as an unbiased coordinator to bring all branches of the industrytogether for the mutually satisfactory adjustment of trade standards;second, to supply such assistance and advice as past experience withsimilar programs may suggest; third, to canvass and record the extentof acceptance and adherence to the standard on the part of producers,distributors, and users; and fourth, after acceptance, to publish andpromulgate the standard for the information and guidance of buyersand sellers of the commodity.When the standard has been4.
