MEASUREMENT OF RUBBER PROPERTIES 5-2-1Property METHOD OF MEASUREMENT ASTM BS ISO

REFERENCE REFERENCE REFERENCERubber Elastomeric (I.e. rubbery or resilient) thermoset.Hardness Measured in degrees and based on the penetration into D2240 BS 903 // ISO 48

the rubber of a defined indentor under a set load. These D1415 Part A26 // ISO 1400scales are commonly used: IRHD (International Rubber // ISO 1818Hardness Degrees), Shore A, and Shore D for hardmaterials over 90o Shore A. IRHD is preferred for mostspecifications but Shore A is also in widespread use.

Tensile This is measured in various units and is expressed as D412 BS 903 // ISO 37Strength a force per unit area. A standard dumbbell type test Part A2

piece of known cross sectional area is used which isstretched until it breaks. The force required to do so is then recorded and expressed as force per unit area.

Elongation Elongation is defined as the length at breaking point D412 BS 903 // ISO 37expressed as a percentage of its original length ( I.e. Part A2length at rest) e.g. if a rubber reaches twice its length before breaking its elongation is 100%.

Modulus Modulus is measured as the force per unit area D412 BS 903 // ISO 37required to extend a rubber to a stated percentage of Part A2its original length e.g. to 100%, 200% or 300%. It isoften written as M100=3.0 Mpa (I.e. modulus at 100% =3.0 Mpa).

Compression A cylindrical button of rubber of known thickness is D395 BS 903 // ISO 815Set compressed to a fixed height (typically 70% or 75% of Part A6

its original height) at a defined temperature for a specified period of time. The button is then released,allowed to recover (typically for 30 mins) and the thickness is measured. Compression set is the height that is not recovered expressed as a percentage of the amount by which it was compressed.

Permanent Set A standard test piece of known length is stretched by a D412 BS 903 // ISO/R 1767(Tensile Set) stated percentage for a period of time and is then Part A5

released. After recovery the length is measured and the change in length (I.e. unrecovered length) is expressed as a percentage of extended length.

Density Density is defined as the mass per unit volume and is BS 903 /// ISO 2781(Specific measured by weighing the rubber sample in air and Part AGravity) water.

S.G =weight in air

weight in air - weight in waterResilience Resilience is measured on standard test equipment D1054 BS 903 // ISO/R 1767

(of which there are several types- e.g. Dunlop, D2637 Part A8Tripsometer, Lupke, Rebound). Standard test pieces are struck by the 'hammer' and the 'bounce back' of the hammer measured. This is expressed as a percentage of the flight path of the hammer.

Chemical This is usually expressed as the change in propertiesResistance (such as hardness, strength and elongation at break)

caused by the presence of chemicals under defined conditions (including concentration, time and temperature).

5-2-2 MEASUREMENT OF RUBBER PROPERTIESProperty METHOD OF MEASUREMENT ASTM BS ISO

REFERENCE REFERENCE REFERENCEFluid Fluid resistance is commonly measured by the effect of D471 BS 903 /// ISO 1817Resistance the fluid on the volume of the rubber expressed as a Part A16

volume change (e.g. + 100% indicates that the volumeof the rubber has doubled as a result of exposure tothe fluid ,- 10% indicates that the volume of rubber has decreased as a result of exposure to the fluid.) Volume change is measured by determining the weight of a sample in air and water before and after exposure tothe fluid under defined conditions.

(W3 -W4)-(W1-W2)Volume change (%) x100 (W1-W2)

Fluid resistance may also be defined in the same way as chemical resistance (above) I.e. by change inproperties of the rubber.W1 Wt in air (initial) W2 Wt in water (initial) W3 Wt in air (swollen)W4 Wt in water (swollen)

Weather Weather resistance is a fairly subjective test and it is D1171 BS 903Resistance necessary to state clearly the conditions under which Part A53

the exposure took place I.e. dates, geographic location, BS 903angle and direction of exposure relative to the sun etc. Part A54The properties of test pieces are measured before and BS 903after sun exposure and expressed as percentage Part A55changes (with the exception of hardness changeswhich are usually recorded in degrees). The change inany property may be measured but the most common are hardness, tensile strength, elongation at break andmodulus at 100% and 300%.

Ozone Ozone causes cracking in rubber. Test pieces are D1149 BS 903 /// ISO 1431/1Resistance usually placed under a small degree of tension e.g. by Part A43

bending round a mandril or stretching by 5%. Thesample is exposed under static conditions to a controlled atmosphere containing ozone (typically50pphm)The cracks are graded by standard photographs, by measurements or by description, e.g. 'visible under 10xmagnification' 'visible to the unaided eye' etc. Resultsmay be recorded as the time taken to reach a particular grade of cracking, or by the grade of crackingapparent after a fixed period of time.

Tear Tear strength is measured as the force is required to D624 BS 903 /// ISO 34Strength tear a standard test piece. The standard test pieces Part A3

are designed to produce weak points where a tear isinitiated.

Abrasion Abrasion properties of rubber are difficult to define. D394 BS 903Resistance Many different abrasion machines have been designed Part A9

but they do not always give similar results. The mostcommon abraders are AKRON, Dunlop and Du Pont.Results are recorded as volume loss per standard testpiece, or as the difference in volume loss when compared with a standard material of known abrasionvalue. Indices of relative abrasion are also used.

Rubber Terms 5-6-1

Calendering Producing rubber in continuous sheets by processing it through a series of rollers.

Compound A general word used to describe a particular formulation or 'recipe', or as a descriptive term for unvulcanised rubber in general. It is used in such applications as 'Compounding ingredients', 'Compound no. XYZ', etc.

Compression Set The degree to which a rubber does not recover fully to its original stateafter it has been compressed for a long period of time.

Curing Also known as vulcanisation, this is the permanent change which the rubber undergoes during moulding. When mixed, rubber compounds arethermoplastic and will melt and deform easily. After curing, the rubberis heat stable.

Elastomer General term used to describe all natural and synthetic polymeric materials which have rubbery or 'elastic' properties.

Extrusion Producing continuous lengths of rubber with a constant profile by forcingit through a die under pressure and vulcanising it. Harboro does not specialise in this sector of the industry.

Heat Ageing Also known as 'accelerated ageing'. Rubber materials are often tested for shorter times at higher temperatures to predict what willhappen over longer times and at lower temperatures.

Modulus The relationship between stress (force) and strain (extended length).Modulus is usually given as the stress (or force) required to extenda rubber.

Polymer General term used to describe all rubbers and plastics. In fact, it is thechemical term used to describe all organic materials which are formed from chains of repeated chemical units.

Resilience The technical term used to describe 'bounce' or 'snap'. Increasing resilience means an increasing 'bounciness'.

Set The degree to which a rubber does not fully recover to its original shapeafter it has been deformed for a long period of time. Also calledpermanent set'.

Thermoplastic Any material which melts on heating and resets on cooling. This melting and refreezing can be repeated indefinitely.

Vulcanisation The permanent chemical change that a rubber undergoes on heatingtogether with chemicals. The chemicals which accomplish this changeare called 'vulcanising agents'.
