Recommendation ITU-T H.845.10 provides a test suite structure (TSS) and the test purposes (TP) for the insulin pump agent in the Personal Health Devices (PHD) interface, based on the requirements defined in the Recommendations of the ITU-T H.810 sub-series, of which Recommendation ITU-T H.810 (2019) is the base Recommendation. The objective of this test specification is to provide a high probability of interoperability at this interface. Recommendation ITU-T H.845.10 is a transposition of Continua Test Tool DG2019, Test Suite Structure & Test Purposes, Personal Health Devices Interface, Part 5J: Device Specializations, Personal Health Device, Insulin Pump (IP-), Version 1.2 (2017-07-18). This edition includes the corrections approved in ITU-T H.845.10 (2017) Corrigendum 1 (11/2017), and the maintenance contents from ISO/IEEE 11073-20601:2022 and ISO/IEEE 11073-10419:2019 (Insulin Pump) versions. This Recommendation includes an electronic attachment with the protocol implementation conformance statements (PICS) and the protocol implementation extra information for testing (PIXIT) required for the implementation of Annex A.
