21、 Methods3. Terminology3.1 Definitions:3.1.1 angle of repose, nwhen particulate solids are pouredonto a flat, horizontal surface, they form a conical pile. Theangle of repose is the interior angle formed between the base ofthis cone and its side (see Fig. 1).3.1.2 bulk density, nthe mass (weight) of

22、particulate solidsdivided by the total volume of sample; that is, bulk density isthe ratio of the mass of large number particles of the materialto the total volume of the sample and is an aggregate propertythat includes the volume(s) of the particles, inter-particleinterstices and particle porosity.

23、 It is expressed as a ratio ofweight/volume; or may be expressed as a unit-less ratioreferenced to a standard material, such as water, as a specificgravity.3.1.2.1 DiscussionIt is not a characteristic intrinsic to amaterial. It is affected by how the sample is handled. Com-monly expressed as “freely

24、 settled” or “poured” density; indistinction to a “tapped” density value that would be deter-mined by a compaction method such as tapping a sample on atable during filling to represent compaction due to varioustypes of vibration. For this guide, poured density would be themost applicable.3.1.3 parti

25、cle size distribution, nthe physical size of theindividual particles in a given sample of a particulate solid. Inalmost all common solids this will be expressed as a particlesize distribution. There are many ways to model or measurethis distribution given the wide variety and irregularity ofparticle

26、 geometries and styles.3.1.3.1 DiscussionThe most effective and common way tomeasure this property is by sieve analysis. Where the particlesize distribution is expressed as a percentage of the weight ofthe sample, retained in each step as the sample is passedthrough progressively finer sieves, to th

27、e weight of the wholesample. See Specification E11 and Table X1.2.3.1.4 specification packaging, na packaging conformingto one of the specifications or standards for packagings in part178 or part 179 of this subchapter (49 CFR).3.1.4.1 DiscussionPackaging, as used in this guide in-cludes packaging c

In addition, packag-

This variation creates significant proble

36、ms inproduct liability, packaging selection and regulatory enforce-ment in this highly regulated industry. Use of this guide shouldenhance uniformity in test procedures.5.2 Consistent and repeatable test results coupled with cleartest fill product descriptions will enhance transportation safetyby si

37、mplifying packaging selection. This will also increase thegeneral level of confidence that package testing, manufactureand use are being guided by sound, generally accepted engi-neering principles. It also aids in clarifying expectationsbetween the packaging industry and the regulatory authorities.5

38、.3 The guide will be used by packaging manufacturers, andpackaging test labs to create packaging test plans that meetcustomer needs and conform to the HMR. In addition, for theuser of a packaging, certain information about the type andphysical characteristics of the material used to test the pack-ag

39、ing must be available in the test report and/or notificationinstruction to allow evaluation of whether a particular packag-ing was tested with a substitute material appropriate for thehazardous material to be shipped.6. Procedure6.1 Packagings may be tested when filled with the actualproduct to be t

40、ransported to the required minimum fill levels.This option is often completely impracticable. Personnel safetyand training, testing facility chemical handling capability,possible site contamination, local regulations or zoning areamong the strongest reasons to use non-hazardous substitutefill materi

41、als for package testing.6.2 A non-hazardous particulate solid may be substituted asa fill material for testing purposes as prescribed in 49 CFR 178.602(c): “If the hazardous material to be transported isreplaced for test purposes by a non-hazardous material, thematerial used must be of the same or h

42、igher specific gravity asthe material to be carried, and its other physical properties(grain, size, viscosity) which might influence the results of therequired tests must correspond as closely as possible to those ofthe hazardous material to be transported.”6.2.1 In the case of particulate solids th

43、e “specific gravity”mentioned in the regulatory citation above often will beexpressed as a bulk density value (g/cm3or lbs/ft3). Thesevalues may be readily converted into a unit-less ratio as aspecific gravity, usually using water as the reference material(water density 1.0 g/cm3).6.2.2 Other charac

44、teristics of fill materials that may influ-ence test results and should be evaluated when selecting asubstitute material:6.2.2.1 Particle (Grain) Size and TypeGrain affects bothflow properties and the ability to detect leakage from thepackage during testing. Smaller grain, freely flowing particu-lat

45、e solids are more readily detectable from potential leak sitesafter tests are performed.6.2.2.2 Flow PropertiesFor particulate solids flow is acomplex property affected by particle size, shape, surfacetexture, etc. As the flow rate of a particulate solids increase,impact and vibratory energy (effect

46、s) are more readily trans-ferred to the packaging.(1) For package testing purposes, much of the complexityof flow can be effectively reduced to a single and fairlystraightforward physical characteristic of a bulk solid known asangle of repose.(a) When particulate solids are poured onto a surface aco

47、nical pile forms. As more material is added the pile becomesboth taller and increases in diameter at a ratio that keeps theangle between the flat surface and the side of the pile nearconstant.(b) There are a variety of methods used to determine theangle of repose for a material. The easiest and most

48、 commonbeing the funnel method. The material is poured through afunnel onto a flat surface. The tip of the funnel should heldclose to the top of the cone as it grows to minimize the effectof impact energy from the particles on the pile. The pile canformed to a predetermined height, width of base or

49、a givenmass of material. (In Fig. 2, the base diameter is the selectedlimit by use of a pedestal structure.) The angle of repose can bemeasured directly from the pile using a protractor, or it can becomputed from the relationship between the diameter (orradius) of the pile and its height. The angle of repose would becomputed by taking the inverse Tangent of the ratio of theheight and the radius (12 diameter) of the base. There are manyrelatively simple and inexpensive funnel type testers availablein the market.(c) It is important to note that some exter
