BS 7140:1995

This standard BS 7140:1995 Airborne noise emitted by woodworking machine tools. Operating conditions for woodworking machines is classified in these ICS categories:

• 17.140.20 Noise emitted by machines and equipment
• 79.120.10 Woodworking machines

This International Standard, together with basic noise emission International Standards, describes the mechanical and acoustical specifications necessary for a reproducible test method for the determination of airborne noise emitted by woodworking machines.

NOTE 1 Acoustic measurement procedures and noise data reporting are given in the basic acoustic standards selected from the ISO 3740 series, ISO 4871 and the ISO 11200 series (see Annex V).

This International Standard specifies operating conditions and microphone positions for the measurement of noise emitted by woodworking machines.

It applies to:

• — single-blade circular saw benches (Annex A);
• — planing machines (Annex B);
• — thickness planing machines (Annex C);
• — single-spindle moulding machines (Annex D);
• — double-end profiling machines (Annex E);
• — edge banding machines (Annex F);
• — double-end sizing and edge banding machines (Annex G);
• — two-side and multi-side planing machines and moulding machines (Annex H);
• — bandsawing machines (Annex J);
• — single-end tenoning machines (Annex K);
• — routing machines (Annex L);
• — double-end trim circular machines (nonstroke) (Annex M);
• — single-blade stroke circular sawing machines for cross cutting (Annex N);
• — vertical and horizontal panel sizing sawing machines (Annex P);
• — multiblade circular sawing machines (for ripping) (Annex Q);
• — sanding machines (Annex R);
• — double-edging circular sawing machines (for rough cutting) (Annex S);
• — double-blade stroke circular sawing machines for cross cutting (Annex T);
• — double-end tenoning machines (for tenoning only (Annex U).

The existence of special-purpose machines, for which such standard operating conditions cannot be specified, is acknowledged. This International Standard applies to the types of woodworking machines listed above. Additional types will be covered in future editions of this International Standard (ISO 7960).
