How do you calculate good compliance sample capacity?

Multiply samples per cycle by available cycles to get gross capacity, then multiply by uptime and first-pass yield. Here 4 x 480 = 1,920 gross, x 0.90 x 0.97 = 1,676 good compliance-tested units.

What's the difference between gross and good capacity?

Gross capacity (1,920 units) is what the bench could test if it never stopped and everything passed. Good capacity (1,676 units) subtracts 192 units lost to downtime and about 52 lost to first-pass failures — the number you can actually certify.

What is a good first-pass yield for compliance testing?

For mature life-safety hardware, first-pass compliance yield above 97-98% is strong; anything below the mid-90s signals a design margin, calibration or process issue that's turning verification into rework rather than confirmation.

Why does uptime matter so much for a compliance test bench?

Certified test stations are often single or few-of-a-kind, so every hour of downtime directly caps how many units you can legally ship. At 90% uptime this example already loses 192 units of capacity before any yield loss.

How can I increase good compliance sample capacity?

Attack the biggest loss first. Here downtime (192 units) outweighs yield loss (52 units), so improving station uptime — faster changeover, preventive maintenance, spare fixtures — buys more good capacity than chasing the last point of yield.

Does this replace a full capacity study?

No — it's a fast planning estimate using blended uptime and yield. For committed ship dates on regulated product, back it with real station logs and lot-level yield history.

Security, Fire & Life Safety Products calculator

Compliance sample quantity Calculator

Compliance sample quantity is the number of good, fully-tested units your compliance or QA line can actually produce in a period once downtime and test failures are accounted for. For security, fire and life-safety products — where UL, FM and NFPA verification testing is mandatory before shipment — this is the real throughput of your listing and quality lab, not the nameplate rate. Quality managers and production planners use it to know whether the test bench can keep pace with build volume. This calculator converts per-cycle output, available cycles, uptime and first-pass yield into realistic good-sample capacity.

What this calculator does

Estimate compliance sample quantity for security, fire and life safety products using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.
Use it when compliance sample quantity in security, fire and life safety products is being asked to take on more work and you need to know if there is room.
It computes the good, compliance-verified sample capacity for a period after applying test-station uptime and first-pass yield to gross capacity.

Formula used

Gross compliance sample quantity capacity = compliance sample quantity output per cycle × available compliance sample quantity cycles
Good compliance sample quantity capacity = gross capacity × expected compliance sample quantity uptime × expected compliance sample quantity first-pass yield

Inputs explained

Compliance test samples completed per inspection cycle:
Available inspection cycles in the period:
Expected test-station uptime:
Expected first-pass compliance yield:

How to use the result

Use it to plan compliance-test bench loading, spot bottlenecks between build and test, and confirm you can certify enough units to meet a ship date.
It models uptime and yield as flat averages; a single long station outage or a bad lot can move actual results well off the calculated figure.

Current U.S. benchmarks

Manufacturing hourly earnings average $30.27 (BLS, Jun 2026), up 4.4% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 529k open positions nationally (BLS JOLTS).
