SIST ETS 300 224:1998/A1:1998

SIST ETS 300 224:1998/A1:1998 is the Slovenian standard identical to ETS 300 224/A1 Edition 1 from ETSI. It amends the Radio Equipment and Systems (RES) standard for on-site paging service, which covers technical and functional characteristics and test methods for on-site paging systems. The change is mainly about extreme-temperature limits and one added definition, so it is useful for manufacturers, test laboratories, and purchasers who need to apply the revised requirements.

What does SIST ETS 300 224:1998/A1:1998 specify?

SIST ETS 300 224:1998/A1:1998 specifies an amendment to ETS 300 224 (1994), not a full rewrite of the paging standard. Its scope is to update the extreme-temperature limits in line with RES04 change request R84.

The amendment is organized around a foreword, an amendments section, and document history. The amendments section points to subclause 3.1 for definitions and subclause 6.3.2 for extreme-temperature testing.

What are the key requirements of SIST ETS 300 224:1998/A1:1998?

New definition in Clause 3.1

SIST ETS 300 224:1998/A1:1998 adds the term transcoder to the definitions in Clause 3.1. A transcoder is a transmitter and encoder in a single indoor fixed housing. In practice, this helps users classify equipment correctly before testing, labeling, or describing it in procurement documents.

Extreme-temperature testing in Clause 6.3.2

SIST ETS 300 224:1998/A1:1998 replaces subclause 6.3.2 with updated temperature-test conditions. Tests at extreme temperatures must use the measurement procedure in subclause 6.3.1, but the ambient range depends on the equipment category.

For base station equipment, the range is -25°C to +55°C. For transcoders used in temperature-controlled environments, the range is -10°C to +55°C. For pocket unit equipment, the range is -10°C to +55°C. For users, this means the test chamber setting must match the equipment type before results are accepted.

Why the separate ranges matter

SIST ETS 300 224:1998/A1:1998 treats the equipment types differently because they are used in different operating environments. That matters in type testing and conformity assessment, where a product can only claim compliance if it is tested under the correct temperature profile.

What terms does SIST ETS 300 224:1998/A1:1998 define?

• transcoder - A transmitter and encoder combined in one housing and used in a fixed indoor location.
• base station transmitter - The existing definition referenced immediately before the added transcoder definition in Clause 3.1.
• base station equipment - Equipment category covered by the revised extreme-temperature test range in Clause 6.3.2.
• pocket unit equipment - Portable equipment category covered by the revised extreme-temperature test range in Clause 6.3.2.
• temperature-controlled environments - The operating condition used to qualify transcoders for the narrower temperature range.
• ambient temperature range - The test temperature span used during extreme-temperature measurements.

Who uses SIST ETS 300 224:1998/A1:1998?

SIST ETS 300 224:1998/A1:1998 is used by manufacturers of paging equipment, test laboratories, and conformity assessment teams that evaluate on-site paging systems. It also helps quality managers and buyers check whether a product description or test report matches the amended temperature conditions.

System designers and service providers use it when deciding whether equipment should be treated as a base station, transcoder, or pocket unit. That classification affects how the equipment is tested and documented.

What changed in SIST ETS 300 224:1998/A1:1998 from the previous edition?

SIST ETS 300 224:1998/A1:1998 amends ETS 300 224 (1994). It adds the definition of transcoder in Clause 3.1 and replaces Clause 6.3.2 with revised extreme-temperature limits for base station equipment, transcoders used in temperature-controlled environments, and pocket unit equipment.

What does the SIST ETS 300 224:1998/A1:1998 document contain?

The document contains amendment text for subclause 3.1 and subclause 6.3.2, plus a foreword and document history. It identifies the amendment as produced by ETSI TC-RES and records it as Amendment 1 to the first edition.

For readers, the useful part is the updated definition and the rewritten temperature-test subclause. Those sections are the ones applied when checking on-site paging equipment against the amended requirements.
