SIST EN 61143-1:1999/A1:1999 is the Slovenian adoption of Amendment 1 to the standard for electrical measuring instruments - X-t recorders, Part 1: Definitions and requirements. It updates the Part 1 text used for specifying, marking and handling X-t recorders, especially the normative references, recorder symbols and safety-related entries.

What does SIST EN 61143-1:1999/A1:1999 specify?

SIST EN 61143-1:1999/A1:1999 is an amendment to Part 1 of the X-t recorder standard. It applies to the existing definitions and requirements text and inserts page-by-page changes to clause 2, Table 4 and Table C - Safety.

In practice, this means the document is not a full standalone rewrite of the subject. It is used together with the base Part 1 text to keep that text aligned with the amended content.

The amendment is organized as a short set of directed edits:

• clause 2, Normative references
• Table 4, Symbols for marking recorders
• Table C - Safety

What are the key requirements of SIST EN 61143-1:1999/A1:1999?

SIST EN 61143-1:1999/A1:1999 mainly changes what the reader must use from the underlying Part 1 standard. The operative effect is limited to deleting specific text and table content from the published edition.

Clause 2 - normative references

SIST EN 61143-1:1999/A1:1999 deletes the two lines concerning IEC 60414 from clause 2. For users, this means the amended Part 1 no longer points to IEC 60414 in its normative references list.

That matters when checking which outside documents govern compliance work. Engineers and buyers should follow the updated reference list in the amended text rather than relying on the earlier edition.

Table 4 - symbols for marking recorders

SIST EN 61143-1:1999/A1:1999 deletes content from Table 4, which covers symbols for marking recorders. In practice, the symbols to be shown on recorders are the ones left in the amended table, not the deleted rows.

This affects product marking, documentation and inspection. Manufacturers and test staff need to use the revised marking set when identifying recorder features.

Table C - Safety

SIST EN 61143-1:1999/A1:1999 deletes six rows of Table C - Safety and also deletes the note attached to that table. For users, the safety table in the amended edition is shorter and should be read in its updated form.

This matters during conformity checking and technical review because safety-related entries in the earlier version are no longer part of the amended table.

Document provenance

SIST EN 61143-1:1999/A1:1999 was prepared by IEC technical committee 85, Measuring equipment for electromagnetic quantities. The foreword also states that approval was based on the FDIS and voting report process, which shows the amendment was handled through IEC's formal consensus procedure.

What terms does SIST EN 61143-1:1999/A1:1999 define?

• X-t recorder - A recorder for showing how a measured quantity changes over time, which is the instrument family covered by the standard.
• Normative references - The outside documents named in the standard that must be consulted when applying it.
• Symbols for marking recorders - The approved symbols used on recorder markings so users can identify features or functions consistently.
• Safety - The table section dealing with safety-related content for the recorders covered by the standard.
• IEC 60414 - A referenced IEC document that this amendment removes from clause 2.
• IEC technical committee 85 - The IEC committee identified in the foreword as the body that prepared the amendment.

Who uses SIST EN 61143-1:1999/A1:1999?

SIST EN 61143-1:1999/A1:1999 is used by manufacturers of electrical measuring instruments, test laboratories, conformity assessment teams, and technical buyers who work with X-t recorders. It helps them apply the amended definitions, understand the updated marking symbols, and follow the current safety table in Part 1.

It is also relevant to quality managers and specification writers who need to compare product markings or technical documents against the amended standard text. In procurement and incoming inspection, it gives the controlled wording to use when checking recorder-related claims.

What changed in SIST EN 61143-1:1999/A1:1999 from the previous edition?

SIST EN 61143-1:1999/A1:1999 makes three stated changes:

• it deletes the two lines concerning IEC 60414 in clause 2
• it deletes six rows from Table 4, Symbols for marking recorders
• it deletes six rows and the note from Table C - Safety

Which standards are used with SIST EN 61143-1:1999/A1:1999?

The amendment names IEC 60414 in clause 2, then removes those references. That is the only external standard specifically identified in the amendment text provided here.

What does the SIST EN 61143-1:1999/A1:1999 document contain?

The document contains a foreword and page-specific amendment instructions. Its operative text points to clause 2, Table 4 and Table C - Safety, and tells the reader what to delete from each place.

It also identifies the preparation route through IEC committee work and voting. For practical use, the document serves as an update sheet for the base Part 1 standard rather than as a complete replacement text.
