Ultimate Guide to Impact Testing Standards (ASTM, ISO, GB)

Global Compliance Map

If you are exporting plastic films, your customers will demand a specific test report. The MLB-01 is your "Compliance Passport" for the following regions.

---

1. ASTM D1709 (USA / Americas)

Standard Test Methods for Impact Resistance of Plastic Film by the Free-Falling Dart Method.

• Relevance: The dominant standard in North America.

• Key Feature: Defines the specific geometry of the dart head (phenolic for Method A) and the "Staircase" calculation logic.

• MLB-01 Fit: Fully compliant with both Method A & B setups defined in this standard.

2. ISO 7765-1 (Europe / International)

Plastics film and sheeting — Determination of impact resistance by the free-falling dart method — Part 1: Staircase methods.

• Relevance: The go-to standard for EU exports.

• Equivalence: It is technically equivalent to ASTM D1709 but uses SI units (grams/Joules).

• MLB-01 Fit: The software allows instant switching to SI unit reporting.

3. GB/T 9639.1 (China)

Plastics film and sheeting — Determination of impact resistance by the free-falling dart method.

• Relevance: The IDT (Identical Adoption) of ISO 7765-1.

• Pharma Application: Referenced in YBB standards for medical packaging (IV bags).

• MLB-01 Fit: As a Chinese source manufacturer, the MLB-01 is the reference machine for this national standard.

Why "Staircase" and not "Pass/Fail"?

All these standards prefer the Staircase Method because plastics are non-homogeneous. One weak spot doesn't define the whole roll. The Staircase method provides a statistical average, which is a much fairer representation of your product's true quality.

Conclusion

Whether you are testing heavy-duty sacks for a US client (ASTM D1709 Method B) or food wraps for a European supermarket (ISO 7765 Method A), the MLB-01 delivers the certified data you need.
