| Quality Management System | Controlled processes for design, purchasing, production, inspection, corrective action, and continual improvement. | ISO 9001:2015 certification issued by a competent, accredited certification body. | Valid certificate, certification scope, issuing body, expiry date, and audit status. | High |
| Environmental Protection | Resistance of the enclosure to dust ingress and temporary immersion in water. | IP67 rating tested according to IEC 60529: the first digit 6 indicates dust-tight protection; the second digit 7 covers temporary immersion up to 1 metre for up to 30 minutes under specified test conditions. | Independent test report identifying the exact enclosure, seals, test method, sample configuration, and result. | High |
| European Market Compliance | Demonstrates that the product meets applicable European Union requirements before being placed on the relevant market. | CE marking supported by applicable requirements, commonly including the Radio Equipment Directive for wireless equipment, EMC, electrical safety, and relevant environmental obligations. | EU Declaration of Conformity, technical documentation reference, test reports, labeling details, and product-model match. | High |
| Radio and Cellular Compatibility | Confirms that the cellular modem and radio interfaces meet applicable technical and network requirements. | Applicable regional radio approvals, cellular industry certifications, and network or operator approvals required for the intended deployment. | Certificates or approval records listing radio technology, frequency bands, antenna configuration, firmware, hardware revision, and supported markets. | High |
| Carrier Certification | Reduces the risk of rejected activation, unstable registration, or non-compliance on a target mobile network. | Carrier approval is market- and network-specific; industry programs such as PTCRB or GCF may support acceptance but do not replace every operator requirement. | Approval ID, supported network bands, SIM or eSIM profile compatibility, VoLTE or data requirements where applicable, and operator acceptance confirmation. | High |
| GNSS Performance Validation | Provides evidence that positioning performance is measured under defined conditions rather than described only by marketing claims. | Documented tests for acquisition time, sensitivity, positioning accuracy, antenna performance, and operation in open-sky and challenging environments. | Test plan, test environment, satellite systems used, sample size, firmware version, accuracy results, and limitations. | Medium |
| Battery and Charging Safety | Helps control risks related to rechargeable cells, transport, charging, overheating, and abnormal operating conditions. | Applicable battery safety, transport, and regional electrical requirements based on cell chemistry, capacity, and product design. | Battery specification, safety test reports, transport test documentation where required, charger parameters, and protection-circuit details. | High |
| Production Consistency | Shows whether certified performance can be maintained across batches and after component or firmware changes. | Documented incoming inspection, in-process controls, final functional testing, traceability, change control, and sample-based reliability checks. | Quality-control plan, inspection records, batch traceability method, failure-rate data, firmware release process, and change-notification procedure. | High |
