Overview of Rubber & Elastomer Testing

Tested by: NABL-accredited partner lab
Regulation: IS 3400 & ISO/ASTM methods
Typical turnaround: 5–10 working days
Sample needed: Parts or test sheets

Rubber parts are specified by a handful of properties: hardness, tensile strength, elongation at break, compression set and how these change after heat ageing or exposure to oil, fuel and ozone. Seals and gaskets that lose their recovery leak; hoses and belts that harden crack. Test methods follow the IS 3400 series and the equivalent ISO and ASTM methods named in automotive and industrial specifications.

Compounders test each batch for consistency, while OEM suppliers test against drawing requirements for PPAP and failure investigations. Material identification by FTIR and TGA shows whether a part is made from the specified polymer, such as EPDM, NBR or silicone. Natural rubber trade itself is overseen by the Rubber Board.

What we do for you

Lab and parameter list chosen for your purpose: licence, export, buyer or internal QC
Sampling guidance, and pickup or on-site sampling where needed
One contact who follows up with the lab until the report is issued
Report explained in plain language, with next steps if a result fails

What to send

The lab confirms the exact quantity and packing for your product when we book the test.

Sample

Quantity: Parts or test sheets
Sealed and labelled with the product name, batch number and date
Packed securely so that it is not damaged in transit

Details to share

Product name, material or grade and intended use
Drawings or specifications, where relevant
The standard or buyer specification to test against
Markets where the product will be sold

How we handle Rubber & Elastomer Testing

1
Assessment of requirement
We confirm the standard, the list of tests and how many samples your product needs.
2
Sample collection
We collect the samples from your factory or warehouse, or tell you exactly where to send them.
3
Right lab assigned
We choose an accredited lab (NABL, BIS-recognised or ILAC) that covers your standard and can start soonest.
4
Testing
The lab tests your samples against the standard. We follow up and tell you at once if a test fails.
5
Test report
You receive the signed test report, ready to use for BIS, WPC, CE or your buyer.

What the lab tests

Parameter	Why it is checked
Hardness (Shore A, IRHD)	Basic compound property
Tensile strength and elongation	Strength and stretch
Compression set	Recovery of seals and gaskets
Heat ageing	Change in properties after hot air exposure
Oil, fuel and ozone resistance	Service fluids and cracking
Polymer identification	FTIR and TGA

The final list depends on your product, its standard and the purpose of testing. We confirm it with you before the sample goes to the lab.

Frequently asked questions

Can you test finished parts rather than sheets?

Many tests can be done on finished parts or specimens cut from them, though results can differ from moulded test sheets. Specifications usually say which is required.

Which standard is the product tested against?

The Indian Standard, international standard or buyer specification that applies to your product and market. We confirm it with you before testing, and the report states the method used for each parameter.

Who carries out the testing?

Instacertify’s partner laboratories, accredited by NABL to ISO/IEC 17025 for the parameters on your report. We choose the lab, arrange the sample, follow up until the report is issued and explain the results to you.
