Oct 1, 2011 · N60-Trim was initially implemented in 2003; by 2007, many of the larger beef companies had widely adopted it. Today, N60-Trim sampling is recognized as the gold standard sampling procedure for beef trimmings destined for raw ground use across the beef industry.

The guidance provides information about procedures for testing for STEC organisms (or virulence markers) using the N60 sample collection method on beef manufacturing trimmings. It applies to official establishments that slaughter or fabricate beef and their ongoing activities to ensure the intended functioning of their food safety programs.

using the N60 sample collection method on beef manufacturing trimmings. FSIS requires that establishments perform ongoing verification activities to ensure their food safety system is functioning as intended (9 CFR 417.4(2)) and support decisions made in their hazard analysis (9 CFR 417.2 and 417.5(a)(1)). Establishment verification testing

N60 is a high manganese, high nitrogen austenitic stainless steel melted as AOD melt type with higher pitting resistance than 316L stainless. This alloy is hardenable to high strength levels through cold working.

nitronic® 60 (n60) centerless ground round bar Nitronic 60 (N60) is an anti-galling and wear resistant austenitic stainless steel. It provides a significantly lower cost alternative to combat wear and galling when compared with cobalt-bearing and high nickel alloys.

N60 is what a safety hammer (cathead and rope) N value is estimated to be uncorrected. An auto hammer is estimated to be about 80% efficient. 1.333 times more than a safety hammer. The N value needs to be corrected to a normalized N60. We find that all SPT hammers, including auto hammers, can vary rig to rig, operator to operator, job site to ...

SPT correction. Several correlations, make use of the energy corrected SPT blow count, denoted as N 60 where 60 is the percentage of the theoretical free-fall hammer energy. Measured blow counts may additionally be adjusted to an effective overburden pressure of 100 kPa which produces the N 1,60 value. In some cases various other factors that influence the SPT results …

Aug 11, 2008 · In Standard Penetration Test we are using N and N60. N60 is the corrected value of N. Why we are writing N60? What is the meaning of this 60?
