EN 300 328 V1.8.1 covers wideband data systems operating in the 2.4GHz ISM band, including WiFi, Bluetooth, and Zigbee. This is the harmonised standard against which manufacturers must issue their Declaration of Conformity for the Radio and Telecommunications Terminal Equipment (R&TTE) Directive.
Its successor, EN 300 328 V1.9.1, is now published and available to download free of charge from the ETSI website. However, it does not provide a presumption of conformity (or compliance) until it is cited in the EU Official Journal.
TÜV SÜD publishes the latest versions of the EU Official Journal in the Legislation Downloads section of its website.
In practice, the publication of this latest revision to the standard means that:
EN 300 328 V1.8.1 is the current harmonised version of the standard, and can be used until it is superseded by EN 300 328 V1.9.1 (likely to be in around 18 months’ to two years’ time).
EN 300 328 V1.9.1 can be used to demonstrate compliance, even though it is not yet cited in the Official Journal, but manufacturers must consult a Notified Body until it is.
When EN 300 328 v1.9.1 is cited in the Official Journal, manufacturers can start to issue their Declaration of Conformity to this version of the standard and self-declare compliance (no Notified Body involvement required). Manufacturers may also continue to declare compliance to EN 300 328 V1.8.1 as long as it is cited in the Official Journal.
Once EN 300 328 v1.9.1 is cited in the Official Journal, a Notified Body can still be involved in the compliance process on a voluntary basis, allowing manufacturers to use the Notified Body number on their product and packaging.
