IP68 and a 1.5-Meter Drop Claim: Two Separate Requirements

IP68 and a 1.5-meter drop claim describe different requirements and need separate evidence. Ingress classification concerns the enclosure. A drop claim needs its own conditions, such as the impact surface, orientations and post-test function checks. Neither phrase automatically proves the other.

Build two lines in the acceptance record

The IEC 60529 publication identifies the enclosure-classification framework. For an environmental test claim, the MIL-STD-810 record is useful background on tailoring. Neither source is a Phonemax model report.

Why the same height can produce different evidence

A phone tested in a case and one tested bare are different configurations. Likewise, a soft landing and a rigid impact surface are not interchangeable. A report should make these conditions explicit so procurement can compare the result with the expected handling risk.

Ask what “passed” meant. It might cover appearance, startup, communications or a longer functional sequence. Do not assume that every component was examined merely because the device powered on.

Write a requirement that can be reviewed

Use a statement such as: “Please supply evidence for the offered phone configuration under our specified drop conditions, with the post-test functional checks and any ingress retest listed separately.” Add the intended conditions to the request; do not copy an unexplained 1.5-meter headline into the purchase order as if its method were already agreed.

Can you drop and submerge the sample yourself?

Do not combine improvised destructive tests at work. Agree a test plan with the supplier or a suitable laboratory, including safe handling and what happens to tested samples. For daily use, follow the selected model's instructions and seek advice after damage.

Review the R4-T's listed features, then ask for model-specific protection evidence. This guide does not claim a verified 1.5-meter result for that model.
