General Introduction

XJB-30A Falling dart impact tester mainly used to test plastic, film, or sheet thickness below 1mm, impact by falling dart, check the energy when 50% of test specimen broken. Conform with standard: ISO 7765, ASTM D1709, GB 9639. Under the given conditions, with A or B method to determine the sample damaged quantity 50% fall quality.


Scope:

Falling dart impact is a traditional method for evaluating the impact strength or toughness of a plastic film. This test uses a single dart configuration and a single drop height, while varying the weight of the dart. Test results can be used either as a quality control evaluation or for end use comparisons.


Specimen size:

Film samples that can be cut to 230 mm x 230 mm (9" x 9") specimens.

A minimum of 30 specimens are required for the test.


A: 38mm dart head weight weight:

1. 38mm dart head with a total weight of 40 grams 1

2. 38mm dart head long rod with a total weight of 70 grams (10g of locking ring) 1

3. 2 weights of 5 grams, 8 weights of 15, 30, 80 and 120 grams


B: 50mm dart head weight weight:

1. 50mm dart head aluminum rod locking ring with a total weight of 120g (locking ring weight 10g) 1pc

2. Two counterweight weights of 15 grams, 8 weights of 45, 90 and 180 grams
