Managing Multi-Market Radio Frequency Exposure Filings for Handheld Transceivers
Handheld exposure filings demand unified 1g and 10g spatial SAR test plans, tight proximity sensor power backoff logic, and deterministic firmware controls.
China GB 21288 2022
Meaning
National technical regulations establish safety requirements for human exposure to electromagnetic fields from mobile communication devices. China GB 21288 2022 specifies the limit values, evaluation methods, and labeling requirements for products operated close to the human ear or body. The standard defines the mandatory compliance boundary for all wireless devices sold in the domestic market, aligning local test protocols with international Specific Absorption Rate guidelines.
Equipment manufacturers must verify that their integrated modules conform to these updated exposure limits before entering commercial channels.
Compliance Mandate
Strict limits govern the maximum exposure permitted during normal operation. The introduction of China GB 21288 2022 updated the previous safety thresholds to include more stringent average power evaluations over specific mass volumes. Compliance requires testing under worst-case transmission configurations.
Labeling Protocol
Consumer awareness drives the mandatory marking on the final product packaging. Under China GB 21288 2022, every compliant terminal must display its maximum Specific Absorption Rate value on the retail box. This clear marking allows purchasers to verify compliance directly.
Certification Procedure
Testing laboratories must run specialized phantoms to collect exposure metrics. The implementation of China GB 21288 2022 requires formal test reports from accredited entities before local type approval is granted. These reports must be held on file by the domestic representative for audit purposes.
