Bursting Strength Tester vs Tensile Strength Tester

Tensile and bursting strength a types of strength of a material that can be measured and help a material withstand in the real world. There are various parameters that help in industries like textile, paper, plastics and packaging. It matters that the Bursting Strength Tester vs the Tensile Strength Tester, which industry uses, its confusion. In this article, read about durability, safety with all global standards of quality. Material is meta, then the strength test becomes easy and also measures its survival rate with accuracy.

What is a Bursting Strength Tester?

• Its a tester that helps in the measurement of the withstand pressure applied to the sample until it reaches up to standard burst pressure.
  
  

• When pressure is applied from a different side, that shows resistance against the state of rupture.
  
  

• Tests are helpful for various purposes in different industries.

Working principle

• Under clamp pressure in the specimen in the setup
  
  

• Pneumatic pressure applied to the specimen
  
  

• The material starts pressed, and it expands until it ruptures
  
  

• Bursting strength is  calculated when the curve shows its breaking point

Applicable Material

• Corrugated boxes
  
  

• Leather
  
  

• Paper
  
  

• Cartons
  
  

• Cardboard

Application

• Multidirectional pressure is applied to materials, like in packaging boxes
  
  

• Helps in understanding stretching in different directions
  
  

• Useful during shipment to avoid any damage
  
  

• Important because the  product should reach the customer in proper condition
  

What Is a Tensile Strength Tester?

• A tensile strength tester helps in measurement before it breaks down
  
  

• It measures elongation, modulus and capacity in load bearing

 How does this work?

• Lower grip and upper grip clamp the material
  
  

• Tension is applied to the machine
  
  

• Specimen pulls over stretch, eventually it breaks down
  
  

• Tensile strength was recorded with the  maximum force

            Material applied

• Metal wire
  
  

• Board and paper
  
  

• Wire of metal
  
  

• Foils
  
  

• Adhesive tapes
  
  

• Rubber
  
  

• Textiles

Application

• One direction force applied
  
  

• Used for tapes, yarn and bags
  
  

• Gives assurance that the material will not fail during shipment
  

Difference between bursting and tensile strength

Parameter Comparison

• Force applied: Bursting Strength Tester → pressure applied multidirectionally | Tensile Strength Tester → pulling force applied unidirectional
  
  

• Aim: Bursting → measure resistance when it bursts under pressure | Tensile → measure resistance through tension before burst
  
  

• Behaviour of material: Bursting → rupture and expansion | Tensile → tensile load, stretchability and elongation
  
  

• Cases use: Bursting → fabrics, cartons and paper | Tensile → plastics, tapes, films and textile
  
  

• Output Measurement: Bursting → kPa or kg/cm² | Tensile → MPa, N, or kN
  
  

• Standard of testing: Bursting → ISO 2758, Mullen Test | Tensile → ISO 1924, ASTM D882
  
  

• Applicable For: Bursting → semi-rigid materials and rigid materials applied in all directions | Tensile → materials pulled in a specific direction

Differences

• Strength is resistance against pressure, which shows bursting strength
  
  

• Tensile focuses on pulling force
  
  

• Both check durability under different conditions
  
  

• Important for shipping and packaging to avoid damage

Which one tests to choose?

        Choose a bursting strength tester

• If the manufacturer of the corrugated box
  
  

• Avoid loss before the bursting condition
  
  

• Helps understand multidirectional force
  
  

• Test knitted fabrics, paperboard and foam
  

Choose a tensile strength tester

• Helps choose elongation, pulling and stretching
  
  

• Applicable for plastic bags, tapes and yarn
  
  

• Resist load in tensile strength
  
  

• Break values increase modulus with % elongation

• Both tests are important to enhance the quality of the material and ensure durability.
  

Relevance of industries - practical uses

• Plastic film strength checked
  
  

• Stretchability and sealing checked

Polymers and plastic

• Durability of plastic films checked
  
  

• Sea level measured
  
  

• Helps detect product defects

Textile industry

• Durability of fabric checked
  
  

• Bursting strength is important for multidirectional force
  
  

• Helps manufacturers build durable materials
