ISO 3164-1979 rus PDF

Full title and description

ISO 3164:1979 — Earth-moving machinery — Laboratory evaluations of roll-over and falling-object protective structures — Specifications for the deflection-limiting volume. This is the third edition published in November 1979; the 1979 edition has been withdrawn.

Abstract

This standard defines the deflection-limiting volume (DLV) — a standardized envelope used in laboratory evaluations of operator protective structures (such as ROPS/TOPS/FOPS) for earth‑moving machinery. The DLV provides dimensional and positioning rules to ensure repeatable test conditions for assessing protective-structure performance.

General information

• Status: Withdrawn.
• Publication date: November 1979 (Edition 3).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 53.100 (Earth‑moving machinery).
• Edition / version: Edition 3 (1979).
• Number of pages: 4 pages (1979 edition).

Scope

Specifies the geometry and placement of the deflection-limiting volume (DLV) to be used when performing laboratory evaluations of roll‑over and falling‑object protective structures fitted to earth‑moving machinery. The scope is limited to the DLV definition and its use as a test envelope for repeatable laboratory assessment of operator protection.

Key topics and requirements

• Definition and dimensional specification of the deflection-limiting volume (DLV) used in testing protective structures.
• Positioning rules for the DLV relative to the seat index point (SIP) to ensure consistent placement during tests.
• Tolerances for linear dimensions, positioning accuracy and permitted rotations during tests to maintain repeatability.
• Application of the DLV in laboratory evaluations of ROPS (roll‑over), TOPS/TOPS‑type tests and FOPS (falling‑object) protective structures.
• Normative references and connection with related ISO requirements for earth‑moving machinery test methods and operator positioning.

Typical use and users

Used by laboratory test houses, OEMs (manufacturers of earth‑moving machinery), safety engineers, conformity assessment bodies and regulatory authorities involved in assessing and certifying operator protective structures. It is applied where repeatable laboratory evaluation of protective structures is required.

Related standards

Closely linked to other ISO documents for earth‑moving machinery and test procedures, for example ISO 6165 (definitions for earth‑moving machinery / machine classes) and ISO standards that define seat index point positioning (ISO 5353) and protective-structure test methods. The 1979 edition was later revised through subsequent editions and ultimately superseded by ISO 3164:2013.

FAQ

Q: What is this standard?

A: ISO 3164:1979 is an International Standard that defined the deflection‑limiting volume (DLV) used in laboratory tests of operator protective structures for earth‑moving machinery. The 1979 (3rd) edition has been withdrawn.

Q: What does it cover?

A: It covers the geometric definition, placement and tolerances of the DLV — the standardized envelope approximating a seated operator — used to evaluate ROPS/TOPS/FOPS in laboratory conditions.

Q: Who typically uses it?

A: Test laboratories, manufacturers of earth‑moving machinery, safety engineers, conformity assessment and certification bodies, and regulators who require standardized laboratory methods for assessing protective‑structure performance.

Q: Is it current or superseded?

A: The 1979 edition is withdrawn (withdrawal recorded in 1992) and the standard was subsequently revised through later editions; the current published version is ISO 3164:2013 (confirmed in review) and has had an amendment published in 2024. For up‑to‑date testing requirements, users should refer to ISO 3164:2013 (and its amendment).

Q: Is it part of a series?

A: Yes — ISO 3164 has been issued in multiple editions (including revisions published in 1992 and 1995) and the subject matter continues in the later consolidated edition ISO 3164:2013 (with subsequent amendments). The 1979 document is an earlier edition in that sequence.

Q: What are the key keywords?

A: deflection-limiting volume, DLV, ROPS, FOPS, TOPS, earth‑moving machinery, laboratory evaluation, operator protection.
