Full title and description

STB DIN EN 1870-12/A1 E 2009-02 — Safety of woodworking machines — Circular sawing machines — Part 12: Pendulum cross-cut sawing machines. This entry is the German national adoption (DIN) of the EN document incorporating Amendment A1 (2009), addressing safety requirements for single‑blade pendulum (pendulum cross‑cut) circular sawing machines used for cutting solid wood, chipboard, fibreboard and plywood (including laminated/edged variants).

Abstract

This standard specifies the significant hazards, hazardous situations and events relevant to pendulum cross‑cut sawing machines and defines safety requirements and protective measures (controls, guarding, braking, interlocks, workpiece supports, marking and user information) to reduce risks to an acceptable level for machines manufactured after the date of publication. It is an amendment (A1) to EN 1870‑12:2003 and is intended to be used alongside general safety standards such as EN ISO 12100.

General information

• Status: National adoption of EN amendment; recorded as withdrawn/superseded in some national catalogs (later consolidated editions of EN 1870‑12 were published).
• Publication date: DIN registration listed as 2009-02-01 (E DIN EN 1870‑12/A1:2009‑02); CEN amendment activity recorded in 2009 (amendment A1 approved in 2009). Later consolidated EN revisions for Part 12 were published (EN 1870‑12:2013 / published 11 Apr 2014).
• Publisher: Deutsches Institut für Normung (DIN) — as national adoption of the European Standard produced by CEN.
• ICS / categories: 79.120.10 (Woodworking machines); related ICS entries for sawing machines also apply (e.g., 25.080.60).
• Edition / version: DIN EN 1870‑12/A1:2009 (Amendment A1 to EN 1870‑12:2003) — indicated as E DIN EN 1870‑12/A1:2009‑02 in national cataloging.
• Number of pages: Approx. 20 pages for the amendment document in some publisher PDFs; consolidated or national printed editions may be longer (some national sale listings show expanded document packages up to ~50 pages).

Scope

The document deals with significant hazards, hazardous situations and events relevant to pendulum cross‑cut sawing machines with a single saw unit designed to cut solid wood, chipboard, fibreboard and plywood, including these materials when covered with plastic laminates or edging. It includes workpiece positioning equipment fitted to the machine. Excluded are machines for cross‑cutting logs and machines where the saw unit rotates about a horizontal axis. For CNC machines, EMC hazards are not covered by this part. The requirements apply irrespective of control method (electromechanical or electronic).

Key topics and requirements

• Identification and listing of significant hazards and hazardous situations for pendulum cross‑cut sawing machines.
• Safety and reliability of control systems: start, normal stop, emergency stop, mode selection, failure behaviours and interlocks.
• Mechanical protection: guards and interlocking of movable guards, guard locking, two‑hand controls where applicable, and measures to prevent ejection of workpieces.
• Braking requirements and tests for saw run‑down, and requirements for braking initiation and performance.
• Toolholder, spindle and saw blade design requirements to reduce risk of break‑up and projection.
• Workpiece supports, guides and clamping to minimise kickback and uncontrolled movement.
• Marking, instruction handbook content and user information required for safe installation, operation, maintenance and disposal.
• Reference to risk reduction principles in EN ISO 12100 and relationship with Machinery Directive essential requirements.

Typical use and users

Primary users are machine manufacturers (design, production, conformity assessment), safety engineers, machine importers and distributors, test laboratories, notified bodies, and workplace safety officers who apply the standard to evaluate and document conformity of pendulum cross‑cut sawing machines. Maintenance personnel and end users consult the standard indirectly via the machine's instruction handbook and conformity documentation.

Related standards

EN 1870‑1 (general safety requirements and tests for circular sawing machines), other parts of EN 1870 (Parts 2–18) covering specific machine types, and EN ISO 12100 (general principles for risk assessment and risk reduction). The EN amendment includes informative annexes relating the requirements to EU Machinery Directive essential requirements.

FAQ

Q: What is this standard?

A: It is the German national adoption (DIN) of the European standard EN 1870‑12 amended by A1 (2009), which sets safety requirements for pendulum (pendulum cross‑cut) circular sawing machines.

Q: What does it cover?

A: It covers hazards, safety requirements and protective measures for single‑blade pendulum cross‑cut sawing machines used to cut solid wood and wood‑based panels (including laminated/edged materials), addressing controls, guarding, braking, workpiece supports, marking and documentation. EMC hazards for CNC variants are excluded.

Q: Who typically uses it?

A: Machine manufacturers, safety and compliance engineers, test labs, notified bodies, purchasers and workplace safety officers — anyone responsible for design, conformity assessment, installation, safe operation or maintenance of pendulum cross‑cut sawing machines.

Q: Is it current or superseded?

A: The 2009 amendment document was a national registration of EN amendment A1. Various national catalogs list this entry as withdrawn or superseded by later consolidated EN revisions of Part 12 (EN 1870‑12 consolidated editions appeared later, e.g. EN 1870‑12:2013 published in 2014). Users should check the current national standards catalog or CEN member body for the latest active edition before relying on it for conformity decisions.

Q: Is it part of a series?

A: Yes — it is Part 12 of the EN 1870 series (Safety of woodworking machines — Circular sawing machines). The series contains multiple parts addressing different circular saw machine types; Part 1 provides general requirements that are referenced by the specific parts.

Q: What are the key keywords?

A: Pendulum cross‑cut, circular saw, guarding, braking, interlock, emergency stop, woodworking machine safety, EN 1870‑12, DIN adoption, amendment A1.
