DOES ANYONE KNOW OF A STANDARD I CAN USE TO TEST IF A PRODUCT (A PLASTIC SAFETY KNIFE ) IS SHATTERPROOF?

One of the snags may lie in the definition of shatterproof (is there one?). We are all familiar with rulers that have the word 'shatterproof' written all over them, and many of us know that you can break them quite easily if you shock load them.
Other plastics get noticeably more brittle when they are cold, and any plastic that is already cracked has much reduced performance.
However, there are two standards that might help:
BS ISO 17281:2002 Plastics - fracture toughness at moderately high loading rates
BS ISO 13586 - Plastics, determination of fracture toughness, a linear elastic fracture mechanics approach.
