AITM 1-0019 is an Airbus test method commonly used to evaluate the tensile lap shear strength of bonded (and similar) composite joints using a single-lap shear coupon configuration.
This method is typically referenced in aerospace material qualification, process validation, and supplier verification where joint performance—rather than laminate-only properties—needs to be demonstrated.

AITM 1-0019 — Determination of tensile lap shear strength of composite joints
AITM 1-0019 is widely associated with single-lap shear testing for composite joint evaluation. It is used when the requirement is tied to Airbus documentation and Airbus-style allowables, qualification evidence, or supplier acceptance data for bonded joints.
Because AITM documents are controlled by the issuing organization, laboratories and suppliers typically follow the exact cited edition from the purchase specification, drawing note, or qualification plan.
Quick Definition
In simple terms: AITM 1-0019 measures the maximum load carried by a single-lap joint pulled in tension and reports lap shear strength for the joint configuration being evaluated.
Typical use: Comparing adhesive / surface preparation / cure cycles, validating a bonded-joint process, or generating joint strength data for aerospace programs.
What This Standard Covers
AITM 1-0019 focuses on coupon-level testing of lap joints where two adherends overlap and are joined (most commonly by an adhesive bondline). The specimen is loaded in tension so the overlap region is stressed primarily in shear, and the resulting failure load is used to determine lap shear strength.
In practice, this method is used to assess joint performance influenced by the adherend material, overlap geometry, bondline quality, surface preparation, cure parameters, and environmental conditioning.
Why This Standard Matters in Testing
For composites programs, laminate properties alone are not enough to qualify bonded structure. Lap shear testing is a common screening and verification tool because it is sensitive to bond quality and process variation.
AITM 1-0019 is often selected when Airbus-specific test evidence is required, or when a supplier’s internal process controls and acceptance criteria are written around Airbus test methods.
Common Materials, Product Types, or Applications Covered
AITM 1-0019 is most commonly associated with aerospace composite joint evaluation, including bonded composite-to-composite joints and related bonded configurations.
Common applications: Adhesive film qualification/verification, bonded repair development, surface preparation validation, production-bond process checks, and comparative studies of bonded-joint performance.
Common Test or Verification Workflow
Most programs use AITM 1-0019 within a controlled coupon workflow where joint specimens are produced to a defined process route and then tested to compare lots, process conditions, or environments.
Common workflow: Prepare lap-joint coupons (with controlled overlap and bondline), apply any specified conditioning, pull the specimen in tension to failure, then calculate lap shear strength from the peak load and bonded area and document the failure mode observations required by the program.
Equipment Commonly Used for This Standard
AITM 1-0019 is typically run on standard mechanical test equipment used for tensile loading, with fixtures and grips that keep the specimen aligned and minimize unintended bending.
Common equipment: Servo-electric or servo-hydraulic universal testing machine, appropriate load cell capacity for the joint strength level, wedge or hydraulic grips (or pin/clevis-style grips when specified by the specimen configuration), and alignment aids/fixtures for lap shear coupons.
When the requirement includes hot/wet or sub-ambient testing, labs commonly add an environmental chamber and the necessary temperature/humidity conditioning capability before testing. If you are specifying machine capacity, grips, or an environmental chamber around an Airbus lap-shear requirement, you can request a detailed quote for a configuration matched to your specimen type and load range.
How to Read This Designation or Revision
Designation: “AITM” indicates an Airbus test method. “1-0019” is the method identifier used in Airbus documentation.
Revision sensitivity: Setup, conditioning, specimen details, and reporting expectations can vary by issue date/edition referenced in a contract or qualification plan. For procurement and compliance, it is good practice to match the exact AITM 1-0019 issue cited by the controlling Airbus or program document.
Related Standards, Methods, or Frameworks
Single-lap shear joint testing is also commonly performed under other aerospace and adhesive-joint methods. Depending on the program, AITM 1-0019 may be referenced alongside other lap-shear or bonded-joint standards used for comparison, supplier equivalency discussions, or internal development testing.
When multiple standards are cited for the same program, keep the equipment and fixturing flexible enough to accommodate differences in specimen geometry, alignment approach, and environmental requirements.
