• MIL-46100 is not adequate to be used in body armor

    From James Waldby@21:1/5 to All on Thu Dec 21 04:52:15 2023
    Subject line is a quote from an Western District of Arkansas US
    District Court ruling[*] dated yesterday, although it isn't any main
    finding, just an "undisputed fact" for legal purposes. The main
    points in the ruling are that the involved metal suppliers and metal fabricators don't bear liability for the 2019 death of a young man,
    Parker L., who wore `armor` from a Texas company, Black Diamond Body
    Armor[*] while a `friend` shot at him with a rifle firing .223 FMJ.

    Black Diamond purchased "certified MIL-DTL-46100E ... steel from
    Leeco" that was delivered to Arkansas Machine Works and/or D&F
    Equipment Sales. The plaintiffs went after those companies with
    claims that they "improperly bent and cut the steel, rendering it
    unfit for its intended use as body armor", via the idea "that AMW and
    D&F???s cutting or bending the steel created weak, hard, or brittle
    spots that caused Parker???s injuries".

    A lot of the judgement is not-so-interesting stuff about statute of
    limitations details, plus technicalities of "breach of warranty" and
    "strict products liability" claims, with a few metal-working items
    scattered through, eg: "Plaintiffs conceded the lack of proof to
    support their theory of liability based on improper cutting and
    bending...", "AMW and D&F offered expert testimony to support their
    contention that the cutting and bending had no effect on the steel???s
    strength and thus could not have contributed to Parker[???s] injury",
    "Based on Plaintiffs??? Brief ... the Court can identify three alleged potential defects: that the wrong type of steel was used in the armor;
    that the subject steel???s Brinell Hardness fell below MIL-46100
    standards; and that Black Diamond represented the steel as being NIJ
    Level 4 rated" (which it isn't). "All three theories are resolved by
    the conclusion that AMW and D&F are not suppliers of body armor under
    the statute".
