About this file
This document is a Notice to Prospective Offerors providing testing procedures and evaluation criteria for PIT (Passive Integrated Transponder) tags submitted under a Department of the Interior solicitation. Vendors must perform all specified tests using equipment they supply, with testing conducted in the presence of Government personnel including the Contracting Officer, Contracting Officer Representative, Contract Specialist, and Technical Proposal Evaluation Committee members. All testing utilizes a Biomark IS1001 reader, the standard reader used by Department of the Interior agencies. Tags are randomly selected from vendor-supplied batches of 1,000 tags, with specific sample sizes required for each test phase. Testing terminates immediately if any tag set fails the stated pass/fail thresholds.
The protocol encompasses five testing phases: Physical Specifications testing of 100 tags for length (≤12.7 mm or ≤9.3 mm for shorter standard tags), diameter (≤2.14 mm), and weight (≤0.115 g); Electrical Performance testing of minimum 200 tags measuring turn-on voltage (≤700 mV), resonant frequency (132–136.5 kHz), bandwidth (<9 kHz), and modulation (>75%), requiring 98% compliance; Interfering Distance testing using five tag pairs at 6-inch and 3-inch spacing with ≥95% efficiency requirement; Minimum Read Distance testing using a 4' x 4' antenna at 0°, 45°, and 66° orientations with 0% and 10% noise levels requiring 8" read distance at 0° and 6" at 45° with 10% noise; and Read Speed testing of 10 tags at approximately 25 ft/sec through a 12-inch shielded antenna with minimum 100 passes per tag at 0° and 45° orientations with 25% noise, requiring ≥95% efficiency. Vendors must submit complete test reports documenting methods, equipment, and results, signed certification of protocol compliance, and identification of any deviations or anomalies.

Notice to Prospective Offerors
This document provides the required instructions, testing procedures, and evaluation criteria for vendors submitting PIT tags for performance testing under this solicitation. All offerors must review and follow the procedures outlined below to ensure consistent, fair, and accurate evaluation of tag performance.
General Instructions
• Vendors must perform all tests described in this protocol.
• Vendors must supply all necessary testing equipment.
• All testing will be conducted in the presence of designated Government personnel, which may include:
o Contracting Officer Representative (COR) o Contracting Officer (CO) o Contract Specialist o Technical Proposal Evaluation Committee members
• All tests will be performed using a Biomark IS1001 reader, the standard reader used by most Department of the Interior agencies for field PIT tag detection.
• For each test, tags will be randomly selected from a batch of 1,000 tags provided by the vendor.
• The required sample size for each test is specified within each section.
• Testing will stop immediately if a tag set fails any pass/fail threshold stated in this protocol.
Offerors are responsible for understanding the criteria, ensuring accurate measurements, and providing complete documentation of results.
PIT Tag Testing Protocol
1. Physical Specifications (Length, Weight, and Diameter)
All tags will undergo physical inspection for structural integrity, including checks for broken housings, missing components, or abnormal shapes.
Measurement Requirements
• Sample size: 100 tags
• Length and diameter:
o Measured to the nearest 0.01 mm using micrometers/calipers o Tags must pass freely through a standard 12-gauge veterinary hypodermic needle o Failing criteria:
▪ Average length > 12.7 mm (or > 9.3 mm for shorter standard tags)
▪ Average diameter > 2.14 mm
• Weight:
o Measured to the nearest 0.0001 g using an electronic analytical balance o Failing criteria:
▪ Average weight > 0.115 g when measured in air
Evaluation Notes
• Tags meeting the preferred length (≤ 12.7 mm) and weight (≤ 0.115 g) will receive favorable consideration during proposal evaluation.
• If tags fail length, diameter, or weight requirements, testing will stop.
2. PIT Tag Electrical Performance Test
This test evaluates electrical characteristics affecting activation and transmission performance.
Tags are tested using a sine wave signal to measure:
• Turn-On Voltage (mV): Minimum energy required for activation
• Resonant Frequency (kHz): Peak transmission frequency
• Bandwidth (kHz): Transmission signal width at -3 dB
• Modulation (%): Effectiveness of transmitting unique identifier
Sample Size
• Minimum of 200 PIT tags.
Passing Requirements
Testing will stop if fewer than 98% of tags meet all of the following:
• Resonant Frequency: 132–136.5 kHz
• Turn-On Voltage: ≤ 700 mV
• Modulation: > 75%
• Bandwidth: < 9 kHz
3. Interfering Distance Test
This test measures detection efficiency when tags are in close proximity to one another.
Method
• Sample size: Five sets of two randomly selected tags
• Tags are run through a 12-inch antenna at a high rate of speed (i.e. 13 ft/sec)
• Tag spacing distances: 6 inches and 3 inches
• Each pair is run through two antennas, 100 times each, for a total of 2,000 detection opportunities per tag type.
Passing Requirement
• Efficiency must be ≥ 95% for both spacing distances.
4. Minimum Read Distance Test
This test determines the distance at which a PIT tag can be successfully detected.
Method
• Conducted using a 4’ x 4’ antenna
• Orientation angles tested: 0°, 45°, and 66° (66° is the most difficult)
• Noise conditions tested: 0% and 10%
• All testing occurs in a fully shielded, noise-free environment
• Tags must have a minimum read distance of 8” for 0° orientation and 6” for 45° orientation at a 10% noise level
5. Read Speed Test
This test evaluates tag readability at high movement speeds.
Method
• Sample size: 10 randomly selected tags
• Tags passed through a 12-inch shielded antenna at high rate of speed (~25 ft/sec)
• Minimum of 100 passes through per tag
• Testing includes:
o Tag orientations of 0° and 45° o 25% noise to differentiate tag performance under adverse conditions
• Tags must maintain ≥ 95% efficiency.
Submission Requirements
Vendors must submit:
• A complete test report documenting methods, equipment, data, and results
• Signed certification that all testing was performed according to this protocol
• Identification of any deviations or anomalies observed during testing
