How Proud Tek measures RFID/NFC durability, read range and compliance
Testing Methodology
Quick answer
This page documents every measurement method Proud Tek uses when it reports a number on an editorial page. We publish this in full so integrators can reproduce our tests, reviewers can challenge our results, and buyers can see exactly what was tested, under what conditions, with what sample size. Every number published on proudtek.com and labelled 'Proud Tek lab test' is produced under one of the protocols below; numbers taken from manufacturer datasheets are cited separately in the sources block. Where we use a published standard as a reference method (IEC 60529 for ingress protection, ISO 6330 for laundry wash cycles, GS1 EPC Tag Data Standard for encoding), we cite the exact revision we followed.
- Industrial-wash durability uses ISO 6330 cycles at 70, 85 and 95 °C with disclosed detergent, liquor ratio and mechanical load.
- Read-range measurement follows ISO/IEC 18046 (UHF) or the NFC Forum analog test plan (HF), with reader, antenna and orientation disclosed per test.
- Sample sizes for any published durability number are ≥30 tags; outliers are reported, not discarded.
- Results labelled 'from manufacturer datasheet' are never relabelled as Proud Tek measurements.

The Proud Tek lab tests the specific use cases our customers ship into. The lab and its rigs are described on the Factory page — this page is the measurement protocols: how each number is produced and reported. We do not claim general-purpose accredited testing; where accreditation matters, we route to a partner test house and cite their report.
- Industrial-laundry wash durability (tunnel-washer cycles, soak, dry) on PPS / silicone / textile RFID tags.
- UHF / RAIN RFID read range at 868 MHz (EU) and 902–928 MHz (US/CA). Free-space and on-item (cardboard carton, PET bottle, cotton garment).
- HF / NFC read range and tap robustness for NTAG / MIFARE Classic / MIFARE DESFire cards under Apple iOS and Android reference handsets.
- Hotel-lock compatibility verification against common Assa Abloy, Dormakaba, Salto, Onity and Saflok door-lock families using physical keycards we encode to the lock's published sector layout.
- Chip programming & issuance validation (UID personalisation, NDEF URL, SUN / AES / DES key provisioning).
Industrial-laundry wash durability protocol
This is the protocol used whenever a page cites a wash-cycle count (e.g. '500 industrial wash cycles').
| Parameter | Method / value |
|---|---|
| Reference standard | ISO 6330:2021 (wash / dry) + IEC 60529 (ingress rating) |
| Wash temperatures | Tunnel-washer emulation at 70 °C, 85 °C and 95 °C |
| Full cycle | Pre-wash + main-wash + rinse + extract |
| Detergent | Alkaline industrial detergent, pH 10.5–11.5 (chlorine-bleach run reported separately) |
| Dry | High-pressure spin + gas tunnel-dryer, 150–180 °C flame / 60–80 °C exit air |
| Verify-read gate | Read after every 25 cycles; failed = two consecutive no-UID reads |
| Sample size | N = 30 per batch |
| Reported as | Median (p50) with 10th and 90th percentile cycle-to-failure — not a single 'up to' maximum |
Read-range measurement protocol
Read range is the number most frequently misrepresented in RFID marketing. Our protocol is deliberately verbose so every published figure can be reproduced.
| Band | Reference method | Always disclosed |
|---|---|---|
| UHF / RAIN | Free-space tag-talks-first distance, ISO/IEC 18046-3 | Reader output power · antenna gain · polarisation |
| HF / NFC | NFC Forum Analog Technical Specification | Reader coil geometry · orientation |
| On-item | Same tag re-measured on carton, PET bottle, cotton and on-metal steel | All surfaces published together — free-space is never shown alone |
| Environment | 22 ± 3 °C, 45 ± 15 % RH, RF-absorbent chamber | Logged per test |
Hotel-lock compatibility verification
Compatibility pages at /compatibility/* are backed by the hands-on test workflow below.
- Step 1 — Lock identification
We capture the lock make, model, firmware (where readable), and sector layout from the customer's field-sampled card.
- Step 2 — Blank stock match
Blank chip family (MIFARE Classic 1K / 4K, MIFARE Plus EV1 / EV2, MIFARE DESFire EV2 / EV3, Legic Advant, HID iCLASS SE) is matched to the lock's accepted families from public lock-vendor documentation.
- Step 3 — Issuance
Keys are provisioned using either the property's issuance software (preferred, produces customer-accepted card) or a generic ACR122U / OMNIKEY rig for compatibility validation only.
- Step 4 — Lock cycling
Card is tapped on the actual lock model (or a sister lock from the same family) for at least 50 successful unlocks; success rate is reported.
What we do not measure (and will not claim)
Explicit negative disclosures are part of the methodology.
- We do not measure long-term RF-exposure safety; we cite the relevant FCC, ICNIRP or EU limits instead.
- We do not make statistical claims about an entire chip family from a single manufacturing lot. All chip durability numbers are traceable to a named lot and wafer run.
- We do not re-publish third-party read-range videos as our own measurements.
- We do not extrapolate beyond our measured range. If we tested to 5 m, we do not claim 'up to 7 m'.

FAQ
Can I audit your lab?
Qualified customers and partners with a signed NDA can request a remote video walkthrough or an on-site visit; contact editors@proudtek.com. We do not currently publish raw logs for confidentiality reasons, but summaries of sample-level percentile distributions are available on request for any number we publish.
Why do you report p10 / p50 / p90 instead of a 'maximum cycles' number?
A peak number is not actionable for procurement. p10 tells the laundry operator what the worst 10% of tags will do, which is what determines shrinkage budgeting; p50 is the median; p90 is what the best tags can reach. Reporting only the peak number is a pattern that reliably misleads buyers into under-budgeting for replacement stock.
How do you decide which numbers become published benchmarks vs. internal QA?
A Proud Tek lab test is publishable only after (a) a second operator has repeated the test on a separate day, (b) the raw data is archived in our lab database with test-ID, operator, instrument serial and environmental log, and (c) the editorial board has signed off. Internal QA numbers that fail any of these three gates are not published.
Do you retract numbers?
Yes. If a number was wrong at publication (wrong sample size, wrong condition, wrong arithmetic) we retract or revise it and log the change at /about/corrections/ with the original value, the corrected value and the date.
