ISO 19709-1:2016

Overview - ISO 19709-1:2016 (Transport packaging, Small Load Container systems)

ISO 19709-1:2016 defines the common requirements and test methods for Small Load Container (SLC) systems used primarily in the automotive industry for handling, transport and storage. Part 1 sets essential performance characteristics for modular, reusable, rectangular SLCs based on area modules such as 600 × 400 mm, 550 × 366 mm and 600 × 500 mm, and is intended to be read together with the particular part that specifies a chosen SLC system.

Key technical topics and requirements

• Scope & modularity: SLCs conform to modular area footprints compatible with standard pallets (e.g., 1 200 × 800 mm, 1 200 × 1 000 mm) to support poolable, reusable packaging systems.
• Nominal loads: Maximum filling mass per SLC is limited (specified maximum is 20 kg).
• Materials: Elements shall be made of recoverable materials; manufacturers commit to polypropylene copolymers and foamed plastics are prohibited. All plastics must be UV-stabilized and compatible with cleaning agents (see Annex C).
• Quality & finish: Uniform, matte colouring and smooth surfaces; permissible minor processing marks if they do not impair fitness for use.
• Stack stability: SLC stacks must remain stable under static and dynamic conditions. Measured deflection under load must meet limits (average deflection < 2% of height; residual deflection < 1%).
• Base deflection tolerances: Dimensional tolerances for base deflection in the delivered (empty) state are specified and measured at (23 ± 2) °C.
• Marking & labelling: Mandatory engraved data (type number, tare mass, manufacturer, manufacture date, recycling symbol) and at least one label holder for scanning/automation.
• Testing & normative references: Test methods are normative (Annex A) and reference standards include ISO 2234 (stacking tests), ISO 2248 (vertical impact), ISO 3676 (unit load dimensions) and IEC 61340-2-3 (electrostatics).

Practical applications and users

Who uses ISO 19709-1:

• Packaging engineers and product designers specifying reusable SLCs
• Automotive supply‑chain and logistics managers implementing standardized unit loads
• Manufacturers and toolmakers producing SLCs and lids
