 STATE OF WISCONSIN 
 
 Office of 
 Dairy and Food Commission and Weights and Measures 
 
 Madison, November 21, 1914. 
 
 To Wisconsin Sealers of Weights and Measures : 
 
 Subsection 6 of section 1659 of the Wisconsin statutes eon- 
 tains the following provision : 
 
 "'The superintendent of ^ ^veights and measures shall 
 issue from time to time,'. I'e'gulaf ions for the guidance of all 
 sealers, and the said regula'ticfns shall govern the procedure 
 to be followed by the aforesaid officers m the discharge 
 of their duties. In said regulations he shall prescribe the 
 amount of tolerance to be allowed." 
 
 In obedience to the requirements of this statute, the following 
 regulations are prescribed for the guidance of sealers of weights 
 and measures in the performance of their official duties so far 
 as the same relate to the subject of Babcock milk test bottles, 
 standard Babcock pipettes, Babcock cream test bottles, and 
 cream test and butter fat test scales, which supersede all previ- 
 ous regulations issued on this subject. 
 
 Babcock ^Milk Test Bottles. 
 
 Babcock milk test bottles coniidyiiig with the following spe- 
 cifications shall be sealed : 
 
 The standard Babcock test bottles for milk shall have a ca- 
 pacity of two cubic centimeters for each 10 per cent marked 
 on the necks thereof. 
 
 The necks of the standard Babcock milk tost bottles shall be 
 graduated from zero to 10 per cent and the graduated scale 
 shall be 75 millimeters in length, with an allowable tolerance of 
 5 millimeters either above or below. The graduated scale shall

be plainly divided into per cent and fifth per cent divisions by 
 lines of tlifferent lenj^tlis. Each per cent graduation shall be 
 numbered and the tolerance for the entire graduated scale or for 
 eitiier half thereof shall not exceed one tenth of one per cent. 
 
 Subsection 1 of section 1494aa of the Wisconsin statutes pro- 
 vides as follows: 
 
 "In the nse of the liabcock test, the standard milk 
 measures or pipettes shall have a capacity of seventeen 
 
 and six tenths cubic centimeters, and the standard test 
 tubes or botth's for milk shall have a capacity of two cubic 
 centimeters for each ten per cent nmrked on the necks 
 thereof; cream shall be tested by weight and the standard 
 vniit for testing shall be eighteen grams, and it is hereby 
 made a misdemeanor to use any other standards of milk or 
 cream measure where milk or cream is purchased by or 
 furnished to creameries or cheese factories and where the 
 value of said milk or cream is determined by the per cent 
 of butter fat contained in the same, or wherever the value 
 of milk or cream is determined by the per cent of butter 
 fat contained in the same by the l>abcoek test." 
 
 Referring to the foregoing provisions of law and other laws 
 prescribing the duties of the state superintendent of weights and 
 measures. Attorney General Owen has i-endered the following 
 official opinion : 
 
 "The fact that the statute says that the standard test 
 tubes or bottles shall have a capacity of two cubic centi- 
 meters for each 10 per cent marked on the necks thereof 
 implies that the necks should have marked thereon the 10 
 per cent mark. I believe that a so-called milk test bottle 
 having only 8 per cent nuirk on the neck is, therefore, 
 not in compliance with the pi-ovision of this law ami you 
 are, therefol-e, instructed that yon would not l)e warranted 
 in ajiproving the same." 
 
 Standard Barcock Pipettes. 
 
 The standard pipettes shall hav(> a capacity of 17.6 cubic 
 centimeters. 
 
 When filled with water at 20° C. delivery shall be in 5 to 8 
 seconds. The tolerance shall not exceed .05 cubic centimeter. 
 
 Note. Section 1494aa of the Wisconsin statutes contains the 
 following provision : 
 
 "Cream shall be tested by weight and the standard unit 
 for testing shall be eighteen grams, and it is hereby made 
 
— 6 — 
 
 a misdemeanor to use any other standards of * * * 
 cream measure where * * * cream is purchased by or 
 furnished to creameries or cheese factories and where the 
 value of said * * * cream is determined by the per 
 cent of butter fat contained in the same, or whereA^er the 
 value of * * * cream is determined by the percent of 
 butter fat contained in the same bv the Babcock test." 
 
 Babcock Cream Test Bottles. 
 
 The standard unit for testing shall be 18 grams. 
 
 Babcock cream test bottles of the following tj'pes and com- 
 plying with the following specifications are to be sealed : 
 
 Type A. Thirty per cent. 18 gram, 6 inch i/o per cent grad- 
 uations. Each 5 per cent on the neck of the bottle shall rep- 
 resent a volume of 1 cubic centimeter. 
 
 The neck of the bottle shall be graduated from zero to 30 
 per cent and the graduated scale 'shall be 75 millimeters in 
 length, with an allowable tolerance of 10 millimeters above or 
 below. The graduated scale shall be plainly divided into 5 per 
 cent, 1 per cent and I/2 P^r cent divisions by lines of different 
 lengths. Each 5 per cent or 10 per cent graduation shall be num- 
 bered. The allowable tolerance for calibration shall not exceed 
 % per cent for the entire graduated scale or for either half 
 thereof. 
 
 Type B. Thirty per cent, 18 gram, 9 inch, .2 per cent grad- 
 uations. 
 
 The neck of the bottle shall be graduated from zero to 30 per 
 cent and the graduated scale shall be 125 millimeters in length, 
 with an allowable tolerance of 15 millimeters either above or 
 below. The graduated scale shall be plainly divided into 5HB^ 
 tf^Pt, 1 per cent and .2 per cent divisions by lines of different 
 lengths. Each 5 per cent or 10 per cent gi*aduation shall be 
 numbered. The allowable tolerance for calibration shall not 
 exceed .2 per cent for the entire graduated scale or for either 
 half thereof. Other specifications same as for Type A. 
 
 Type C. Forty per cent, 18 gram, 6 inch, i/^ per cent grad- 
 uations. 
 
 The neck of the bottle shall be graduated from zero to 40 
 per cent and the graduated scale shall be 75 millimeter^ in 
 length, with an allowable tolerance of 10 millimeters either above

 All other specifications are to be the same as for Type A. 
 
 Type D. Fifty per cent, 18 gram, 7 inch, I/2 per cent gi'ad- 
 nations. 
 
 The neck of the bottle shall be graduated from zero to 50 
 per cent and the graduated scale shall be 105 millimeters in 
 length, Avith an allowable tolerance of 13 millimeters either above 
 or below. 
 
 All other specifications are to be the same as for Type A. 
 
 Type E. Fifty per cent, 18 gram, 9 inch, 1/2 per cent grad- 
 uations. 
 
 The neck of the bottle shall be graduated from zero to 50 per 
 cent and the graduated scale shall be 125 millimeters in length, 
 with an allowable tolerance of 15 millimeters either above or 
 below. 
 
 All other specifications are to be the same as for Type A. 
 
 Referring to the provisions of section 1494aa of the Wisconsin 
 statutes hereinbefore quoted. Attorney General Owen has ren- 
 dered the following official opinion relative to 9 gram cream test 
 bottles : 
 
 "Under this statute it is provided that 'cream shall bo 
 tested by weight and the standard unit for testing shall 
 be 18-grams and it is hereby made a misdemeanor to use 
 any otlier standards of milk or cream measure,' etc. As 
 18 grams are expressly mentioned as the standard unit 
 used in testing, and as no mention is made of a 9-gram 
 standard unit, I am of the opinion that only the 18-gram 
 cream test bottles can be used and the 9-grara cream test 
 bottles should be condemned." 
 
 Cream Test and Butter Fat Test Scales. 
 
 The scale shall be provided with a graduated plate of at least 
 ten divisions over which the pointer plays. 
 
 The pointer shall reach' to the graduated divisions and shall 
 terminate in a fine point to enable the readings to be made 
 clearly and distinctly. 
 
 The cleai* interval betw^een the divisions on the graduated 
 plate shall not be less than .05 inch. 
 
 All scales whose weight indications are changed by an amount 
 greater than one half the tolerance allowed, when set in any po- 
 sition on a surface making an angle of 3 degrees or approxi- 
 mately 5 per cent with the horizontal, shall be equipped with 
 
o y

 leveling screws and with a device which will indicate when the 
 scale is level. Provided, however, that the scale shall be rebal- 
 anced at zero each time its position is altered during this test. 
 
 The scale shall be so constructed and adjusted that when the 
 pans are released or disturbed the pointer will return to rest at 
 the zero mark. 
 
 The addition of 32. -1 niilligranis or one half grain to the scale 
 when loaded to capacity shall cause a movement of the pointer 
 at least equal to one division on the graduated plate. 
 
 The tolerance either in excess or deficiencj^ when the scale is 
 fully loaded shall be one grain. 
 
 Weiglits. A tolerance of 20 milligrams is allow^able in 18 
 gram w'(?ights and 10 milligrams in 9 gram weights. The man- 
 ufacturers' tolerance shall be one half this amount. 
 
 Note. To avoid liability of penalty for violation of the 
 Aveights and measures law^ by the use of any unsealed weight, 
 scale, measure or measuring appliance of any description, in- 
 eluding new appliances, or any such appliance that has not been 
 sealed wdthin one year, owners of the same should give notice in 
 writing to the s^ate superintendent of weights and measures, 
 ^ladiscii, Wis., or to the city scaler if in a city having a city scaler 
 of weights and measures, of the fact that they have such weight 
 or measure or weighing or measuring device, giving a descrip- 
 tion of the same and its location. See subsection 3, section 4432 
 AVisconsin statutes.

 To Cheese Factory and Creamery Managers, Cheese Makers 
 and Butter Makers : 
 
 Paragraph 3 of section 1659 of the Wisconsin statutes re- 
 lating to weights and measures places a general supervision of 
 all weights and measures and weighing or measuring devices of 
 the state in the hands of the state superintendent of weights 
 and measures. It further provides that he or his inspectors b}^ 
 his direction shall, upon the written request of any citizen, firm 
 or corporation, or educational institution of the state, test or 
 calibrate weights, measures, weighing or measuring devices, and 
 instruments or apparatus used as standards in this state. 
 
 Under the provisions of this act, owners of creameries and 
 cheese factories may send to the office of weights and measures 
 at Madison, Wis., any Babcock milk, cream, or butter test 
 bottles, any milk pipettes, and any scales or weights used in 
 the weighing of cream samples, and the same will be tested. 
 No fees are charged for testing. Many managers are now or- 
 dering their new supplies sent direct to the office of weights 
 and measures for testing and sealing, thus insuring accuracy 
 before being put to use, mth little or no inconvenience. In 
 sending in old glassware, it is best to send only part of the sup- 
 ply on hand- at one time, as sometimes several weeks may elapse 
 before the glassware can be returned. 
 
 In' sending apparatus for testing and sealing the following 
 rules should be complied with : 
 
 1. Address all packages to J. Q,. Emery, Office of Weights 
 
 and Measures, State Capitol, Madison, Wis. 
 
 2. The name and address of consignor should be placed on 
 
 the outside of the package. 
 
 3. Transportation charges on packages should be prepaid. 
 
— 11 — 
 
 4. If consignor desires package to be returned by parcel 
 
 post, postage should be enclosed in letter to pay for 
 return of same. 
 
 5. Bottles to be tested must be thoroughly cleaned before 
 
 sending, so that all sediment or deposit on the inside 
 of the bottles is removed. No tests will be made of 
 glassware that is not thoroughly clean when submitted. 
 
 6. Extreme care should be exercised in packing such glass- 
 
 ware or scales for shipment, as this department will 
 not be responsible for breakage.
