The standard provides a standardized test method for measuring the energy required to puncture board using a pendulum-type testing device. It is applicable to different types of board, including corrugated fibreboard and solid board, and is particularly relevant to materials used for manufacturing packaging cases.

What is IS 19535 : 2026?

IS 19535 : 2026 is the Indian adoption of ISO 3036 : 2025 covering the determination of puncture resistance of board using a pendulum device.

The test method provides a consistent way to evaluate the resistance of board to puncturing forces. Such performance can be important for board used in transport and packaging applications where the material may be subjected to impacts from corners, edges or other concentrated forces.

What is Puncture Resistance?

Puncture resistance represents the ability of a board material to resist penetration when subjected to a concentrated impact. The pendulum test provides a standardized method for determining this property under controlled laboratory conditions.

The result can assist manufacturers, laboratories and packaging professionals in comparing board performance and verifying material characteristics against relevant product or procurement specifications.

Boards Covered Under IS 19535

According to ISO 3036 : 2025, the method is applicable to all types of board, including:

• Corrugated fibreboard

• Solid board

• Board used in the manufacture of packaging cases

• Other board materials where puncture resistance needs to be evaluated

Purpose of the Pendulum Puncture Test

Board used for packaging may be exposed to mechanical impacts during handling, storage and transportation. A standardized puncture-resistance test allows the material's resistance to localized impact to be assessed under repeatable laboratory conditions.

The test can support quality control, material comparison, packaging development, supplier qualification and technical evaluation of board used for protective packaging applications.

IS 19535 and ISO 3036 : 2025

IS 19535 : 2026 adopts the international test method identified as ISO 3036 : 2025. ISO identifies the 2025 publication as the second edition of ISO 3036 and classifies it under the paper and board field.

ISO 3036 : 2025 was published in March 2025 and replaces ISO 3036 : 1975 at the international level.

Who Uses IS 19535

This standard is a working reference for:

• Paper and board manufacturers: To evaluate puncture resistance as part of product testing and quality control.

• Corrugated packaging manufacturers: To assess board intended for cartons, boxes and packaging cases.

• Testing laboratories: To conduct puncture-resistance testing using a standardized pendulum method.

• Packaging engineers: To compare board performance when selecting materials for packaging applications.

• Quality assurance teams: To verify incoming material or production samples against applicable specifications.

Is BIS Certification Required Under IS 19535?

No. IS 19535 : 2026 is a method-of-test standard. It describes how puncture resistance of board is determined and is not itself a product specification against which an ISI Mark licence is directly issued.

A specific board or packaging product may nevertheless be subject to other applicable Indian Standards, purchaser specifications or regulatory requirements depending on its intended use.
