3 Introuction For arness testing of elastomers an plastics, Sore urometers are ieal. Sore urometers conform to all ASTM an international stanars an are easy-to-use. Tis brocure contains urometers an urometer systems tat cover te entire spectrum of inentation arness testing of rubber-like materials. Eac urometer type is mae to a specific scale (i.e. A,B,C,D) an is capable of proucing a value between 0 an 100. For M scale testing, Sore manufactures te micro system, wic is esigne to etermine te arness of soft elastomers too tin or too irregularly sape, suc as small o-rings, for measurement wit macro urometers. All urometers except for te M scale units can be use as a portable evice. Test stans are recommene for best accuracy an are require for M scale testing ue to its increase sensitivity. Sore S1 portable igital urometer an various rubber specimens Sore Test Meto Te Sore test uses a arene inenter, an accurately calibrate spring, a ept inicator, an a flat presser foot. Te inenter protrues from te mile of te presser foot an extens 2.5 mm from te surface of te foot. In te fully extene position te inicator isplays zero. Wen te inenter is epresse flat even wit te presser foot's surface, te inicator isplays 100. Terefore, every Sore point is equal to mm penetration (M scale is mm). To perform a test, te unit is place on te sample so tat te presser foot is el firmly against te test surface. Te spring puses te inenter into te sample an te inicator isplays te ept of penetration. Te eeper te inentation, te softer te material an te lower te inicator reaing. Te Sore A an D scales are by far te most commonly use. Te M scale uses a very low force spring an was evelope to allow testing very small parts like o-rings tat cannot be teste in te normal A scale. Because ifferent materials respon to te test scales in ifferent ways, tere is no correlation between te ifferent scales. Sore test metos are efine in te following stanars: DIN ISO 7619 Part 1 JIS K 6253 ASKER C-SRIS-0101 * (now obsolete) * Please consult factory for availability of Sore urometer for ASKER C testing.

10 Manual Stans for Roun an Digital Durometers Sore operating stans are use to improve te accuracy an reproucibility of bot analog an igital urometer arness tester reaings by ensuring tat te presser foot is exactly parallel to te specimen table. Any analog or igital urometer can be mounte on an applicable operating stan. Te operating stan is primarily intene for use on a test specimen wit parallel sies. Irregularly sape objects may be teste in a nest or a fixture to make te given surface parallel to te urometer presser foot. specifies tree categories of operating stans: Type 1 are basic, manual operating stans. Type 2 are stans capable of controlling te rate of escent Type 3 are yraulically, pneumatically or electromecanical riven. DR DRCL Sore manufactures stans tat fall into all tree categories. For assistance in selecting te proper operating stan to fit your urometer, please refer to te Sore 'Stan Selection Matrix' foun on page 12.

11 Principle of Operation Te DR an DRCL (DR constant loa) stans provie a stable mounting an test fixture for eiter analog or igital urometers. Bot moels allow you to ajust specimen table an urometer eigts. Wen a urometer is mounte an properly aligne, te urometer's presser foot is exactly parallel to te specimen table on te stan, ensuring accurate an repeatable reaings. Te DR stan requires tat you manually lower te urometer an ten apply appropriate pressure to te specimen. In contrast, te DRCL stan provies a loaing weigt of known value for tis purpose. Variation in te velocity of urometer application is a common cause of ifferences in arness reaings. For example, wen testing materials wit ig creep properties, false reaings may be obtaine if te urometer is improperly or rapily applie to te surface. Te CV conveloaer features a constant loa weigt an a yraulic cyliner tat automatically controls te application velocity of te urometer. Wen you release te pawl lever, te weigt rives te urometer ownwar at a steay rate, controlle by te calibrate yraulic aspot. Te urometer contacts te specimen at a constant spee an force, ensuring repeatable an accurate test results. Te LR leverloaer features a constant loa weigt for igly accurate an reproucible arness reaings. To operate, te lever is epresse to raise te specimen to te urometer, wic in turn lifts a constant loa weigt seate on a saft above te instrument. Te mass of te urometer an instrument saft assembly, in combination wit te small weigt, prouces te mass necessary for Types A, B, an O urometers. Te aition of te large weigt prouces te mass necessary for Types C, D an DO urometers. Te urometer an instrument saft assembly prouces sufficient mass for testing wit Type OO urometers.

12 Automatic Operating Stans Sore 900 an 902 automatic operating stans are Type 3 stans, as escribe in. Te key avantage of automatic stans is teir ability to perform ans-off ig volume testing between 300 to 400 cycles per our. For assistance in selecting te proper operating stan to fit your urometer, please refer to te Sore 'Stan Selection Matrix' foun at te bottom of tis page. Principle of Operation Automatic operating stans provie bot constant loa an application velocity, troug a gear-riven electric motor an braking mecanism tat alternately lowers te urometer onto te specimen an ten raises it in preparation for te next testing cycle. Tis automatic return ensures tat every test as te same starting point. Electronic controls are use to ajust te amount of time te urometer remains in te raise or lowere position, allowing time for te cangeout of specimens an te recoring of reaings. S1 urometer mounte on a 902 automatic stan Stan Selection Matrix Te Sore 900 automatic stan is esigne primarily for analog urometers.

15 IRHD Durometers an Stans Te International Rubber Harness Degrees (IRHD) test was evelope in Europe several years ago as an alternative to te Sore test. It is intene to provie an inication of te elastic moulus of te material being teste. Using a scale of 0 to 100, a reaing of zero represents a material wit zero elastic moulus an a reaing of 100 represents a material wit infinite elastic moulus. A curve is provie in te ASTM stanar to efine te intermeiate values. One IRHD point is equal to 0.04 mm penetration. Principle of Operation Te Sore IRHD test is similar to a Rockwell test in tat two test forces are use to measure te ept of penetration. Te inenters are steel balls; IRHD units are not portable an can only be use in a stan esigne for te test. IRHD testing is covere by test metos ASTM D 1415 an ISO S 48, meto N. Test specimens are generally in te range of 8 mm to 10 mm, but soul not be less tan 4 mm in tickness.

Wit te urocalibrator, a urometer verification can be performe wit greater precision tan stanar rubber test blocks, tereby proviing a quick an accurate assessment of your urometer's performance an calibration status. Te urocalibrator can eliminate costly prouction errors by quickly ientifying out of tolerance conitions. Principle of Operation Te Sore urocalibrator excees te precision requirements manate by ASTM specs. ASTM requires tat 822 g mainspring urometers ave a tolerance of ±8.2 g at every 10-point increment an tat 4550 g mainspring urometers ave a tolerance of ±45 g for every 10-point increment. Te Sore urocalibrator elivers ±2 g for 822 g mainspring an ±5 g for 4550 g mainspring urometers. Te eart of te system is te beam an sliing weigt. Te beam is ar crome-plate to resist wear to te etent points an knife-ege; an te sliing weigts ave arene etent pins wic are also wear resistant.

18 Resiliometers Te Sore resiliometer measures resilience of elastomers by ropping a plunger of controlle weigt an geometry from a fixe eigt on te test specimen. It is especially useful in eveloping compouns to absorb vibration. Te lower te resilience, te less vibration transmissibility. Te Sore resiliometer is to resilience wat te Sore urometer is to inentation arness. It complements te Sore urometer an measures an entirely ifferent property. Unless te resilience as well as te arness of compouns are ientifie, te compouns are not fully teste. Using bot instruments raises quality control levels to its peak. Principle of Operation Te reboun is measure by observing te eigt to wic te top of te plunger rebouns on te 0 to 100 scale. Base, post, scale, plunger, brus, pass or fail mask.

20 How to Maximize te Performance of your Sore Durometer Alignment It is critical tat te presser foot is flat against te surface of te sample uring te test. Carefully position anel units so tat te presser foot is in even contact an te inenter is perpenicular wit te test surface. Any eviation will cause low reaings. Wen using a stan, low reaings frequently result wen te unit is mounte at a sligt angle so tat te presser foot is not parallel wit te sample supporting surface. Te smallest angle will cause errors. Use te alignment tool provie wit te stan for best results. Test Times Wen comparing results it is important to use te same test times. Some materials exibit a large egree of flow after te full test loa is applie. A one or two secon ifference in taking te reaing can cause significant variations. Constant Force Te force use to press te urometer against te test surface soul be constant. Too little force may not allow te presser foot to be in firm contact wit te surface of te part. Too muc force may cause te material to flow into te inenter opening resulting in an excessive compressive stress tat will effect te Sore reaings. Tis is particularly true for softer materials. Wen comparing results always make sure te force is te same. Roun Part Testing Small roun parts, like o-rings, are particularly ifficult to test. Care must be taken to align te centerline of te sample wit te centerline of te inenter. Any offset will cause low reaings. Te M scale was esigne for testing o-rings an must be use for any tat are too small for te A scale. Sample Tickness efines te minimum tickness of parts to be teste. Testing tinner samples may result in ba results. Parts can frequently be stacke or plie to get to te require tickness. If stacking is not possible, some testing may be require to make sure te tickness is not causing ba results. Typically parts tat are too tin will give results tat are too ar. Define Test Parameters No matter wat test metos you use always ocument tem on te test report so tat tey can be reprouce. Regular Calibrations All instruments are subject to rift over time. Frequent testing wit test blocks will elp you monitor te performance of testers on a ay-to-ay basis. Rubber test blocks, owever, are subject to arness canges as tey age. Terefore, annual irect calibrations are important to maintain a stable testing program.
