Описание (английский):

La présente Norme internationale prescrit une méthode pour la détermination de la valeur comparative d'impact de joints adhésifs en cisaillement, lorsque les essais sont effectués sur des éprouvettes normalisées dans des conditions prescrites de préparation, de conditionnement et d'essai. La méthode est en principe applicable à des joints collés de bois ou de métaux, mais elle peut être étendue à des joints collés de plastiques ainsi qu'aux combinaisons de ces substrats.

Overview

ISO 9653:1998 specifies a standardized test method for measuring the shear impact strength of adhesive bonds. This internationally recognized procedure, developed by ISO Technical Committee ISO/TC 61 on plastics, ensures consistent evaluation of adhesives under impact shear conditions. The standard applies primarily to adhesive joints between metals and wood but can also extend to plastics and combinations of these materials. It defines requirements for specimen preparation, conditioning, testing apparatus, and reporting methods to determine the energy absorbed by bonded joints during shear impact.

Key Topics

Scope and Applicability
Defines the method for comparative impact testing of adhesive shear joints using standardized specimens under controlled conditions. Applicable to metal-to-metal, wood-to-wood, and plastic-to-plastic adhesive bonding.

Test Principle
Uses a pendulum-type impact testing machine operating at 3.4 m/s to apply shear impact force to standardized specimens, measuring the absorbed energy in joules per square meter.

Specimen Preparation

Metal specimens typically have defined block dimensions ensuring consistent impact area.
Wood specimens require straight-grained, defect-free hardwood with specific moisture content and orientation for reproducibility.
Plastic specimens must follow manufacturer surface preparation in line with ISO 13895.
Adhesive application follows the manufacturer’s recommendations, with removal of excess adhesive to ensure accurate impact transfer.

Conditioning Requirements
Specimens are conditioned at 23 °C and 50% relative humidity in accordance with ISO 291, with special protocols for wood moisture equilibrium and optional aging as per ISO 9142.

Impact Testing Procedure
Detailed guidance on mounting, alignment, impact head contact, energy measurement, and fracture face examination following ISO 10365.

Result Calculation and Reporting
Impact strength calculated as energy absorbed divided by adhesive surface area (J/m²). Test reports must include adhesive identification, test conditions, specimen details, fracture type, and impact values.

Applications

ISO 9653:1998 is essential for industries relying on adhesive bonding performance under dynamic loading, including:

Automotive and Aerospace: Assessing adhesive reliability in shear impact conditions critical to safety components.

Wood and Furniture Manufacturing: Evaluating bonded joints for durability against shocks.

Metal Fabrication and Assembly: Testing bonding strength in metal parts subject to sudden loads.

Plastic Product Development: Verifying impact resistance of bonded plastic assemblies using appropriate surface preparations.

Quality Control and R&D: Providing standardized data for adhesive selection, formulation adjustment, and process optimization.

Related Standards

ISO 9653:1998 references and complements several ISO standards critical for thorough adhesive bond analysis:

ISO 291:1997 - Conditioning atmospheres for plastics and adhesives.

ISO 4588:1995 - Surface preparation guidelines for metals prior to bonding.

ISO 9142:1990 - Laboratory aging conditions for adhesive-bonded assemblies.

ISO 10365:1992 - Identification and classification of fracture surfaces in adhesive joints.

ISO 13895:1996 - Surface preparation for plastics bonding.

ISO 6237:1987 - Determination of shear strength of wood-wood bonded joints (referenced for wood species and moisture details).

By following ISO 9653:1998, manufacturers and testing laboratories can ensure reliable, reproducible measurement of shear impact strength-an essential parameter for evaluating the safety and performance of adhesive bonded components in dynamic applications.
