A

2、 number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.

5、ation for Sampling and Testing of ReusableLaboratory Glassware2.2 Other Document:NIST Handbook 44, Section 4.44 Graduates33. Classification3.1 Graduates shall be in the following types and sizes:3.1.1 Type 1Graduated in metric scale only.3.1.1.1 Sizes5, 10, 25, 50, 100, 250, 500, and 1000 mL.3.1.2 T

6、ype 2Graduated in both metric and inch-poundscales.3.1.2.1 Sizes5 mL and 60 minims, 10 mL and 120minims, 15 mL and 4 fluid drams, 25 mL and 8 fluid drams, 50mL and 2 fluid oz, 100 mL and 4 fluid oz, 250 mL and 8 fluidoz, 500 mL and 16 fluid oz, and 1000 mL and 32 fluid oz.NOTE 1The term millilitre (

7、mL) is commonly used as a special namefor the cubic centimetre (cm3) in accordance with the International Systemof Units (SI). (The inch-pound fluid ounce is equivalent to 29.5735 mL,hence, the fluid dram is equivalent to 3.6967 mL and the minim isequivalent to 0.0616 mL).4. Material and Annealing4.

8、1 Graduates shall be made of borosilicate glass conform-ing to the requirements of Type 1, Class A of SpecificationE438.4.2 Maximum residual thermal stress shall be such as toconform to Specification E671.5. Design5.1 StyleGraduates having a capacity of more than 15 mL(4 fluid drams) may be either c

9、onical or cylindrical. Thosehaving a capacity of 15 mL or less shall be cylindrical.5.2 DimensionsThe inside measurement from the bottomof the graduate to the top capacity graduation shall be not lessthan five times the inside diameter on a cylindrical graduateand two times on a conical graduate. Th

10、e inside measurementfrom the bottom of the graduate to the point representing onefourth of the capacity shall not be less than the inside diameterat that point.5.3 Pour-Out SpoutAll graduates shall have a pour-outspout that ensures delivery of an unbroken stream of liquidwithout wetting the outside

11、wall of the graduate.5.4 BaseThe base shall be perpendicular to the verticalaxis of the graduate. The base shall be large enough so that theempty graduate will stand on a surface 15 from the horizontal.6. Graduations6.1 Each graduate shall have clear graduation markingsperpendicular to the vertical

12、axis of the graduate and parallel toeach other. They shall conform to the requirements of Speci-fication E694.6.1.1 No graduation line shall extend less than one fourththe circumference of the graduate. Graduates shall have aninitial interval that is not subdivided, equal to not less than onefifth a

13、nd not more than one fourth of the capacity of thegraduate. Except for this interval, the values of all graduated1This specification is under the jurisdiction of ASTM Committee E41 onLaboratory Apparatus and is the direct responsibility of Subcommittee E41.01 onApparatus.Current edition approved Nov

Numerals shall be uniformly positioned, either di-rectly upon or immediately above the graduation line to whichthey refer. Numerals shall be set in from the ends of the linesa suffic

17、ient distance to permit the line ends to be used inmaking a meniscus setting.6.1.2 Type 1 graduates shall have main graduation lines thatencircle the graduate at least 90 %. Intermediate lines shallextend at least 50 % of the circumference of the graduate.6.1.3 Type 2 graduates (double scale) shall

18、have a clearspace between the ends of the main graduation lines of the twoscales. This space shall be approximately 90 % removed fromthe pour-out spout of the graduate and shall comply to therequirements of Table 1.6.2 Graduation Marking Details:6.2.1 Capacities, graduation ranges, values of graduat

19、edintervals, and numbered graduations applicable to single-scalegraduates and to appropriate portions of double-scale gradu-ates, are shown in Table 2.6.2.2 Permanency of MarkingsGraduation markings shallbe permanent and legible. They shall be applied by etching andfilling with a permanent pigment,

20、by firing a ceramic enamelinto the glass without etching, or by applying a stain and firinginto the glass without etching.6.3 Tolerances shall be as shown in Table 3 and in accor-dance with Table 3 of Section 4.44 of NIST Handbook 44.Pharmaceutical graduates are calibrated “to deliver” and at20C. Th

21、e tolerance applicable at a specific graduation line isdetermined by the inside diameter of the graduate at the pointin question.7. Markings7.1 Each graduate shall be permanently marked with thename or trademark, or both, of the manufacturer; the letters“TD” or “EX,” or both; the calibration tempera

22、ture, 20C; andthe units of capacity, such as mL for Type 1 graduates, and mLand minims, fluid drams or fluid oz, for Type 2 graduates.8.
