BS 476-12
Structure
1.Voltage:220V + 10%, 50Hz;
2.Burner.
(1)Ignition source D. A gas burner comprisinga 185 mm long horizontal stainless steeltube(12.0 mm outside diameter, 9.0 mm insidediameter) closed at each end and fitted with acentral gas supply pipe. The burner tube shall havea row of 14 holes of 1.5 mm diameter at 12.5 mmcentres arranged so that the gas jets issue at anangle of 45 below the horizontal.
Theflowmeter shall be calibrated to supply a propanegas flow rate at 25C of 2 l/min
NOTE: Under these conditions the flame height isapproximately 240 mm.
(2)Ignition source E. a gas burner comprisinga 185 mm long horizontal stainless steeltube(12.0 mm outside diameter, 9.0 mm insidediameter)closed at each end and fitted with acentral gas supply pipe. The burner tube shall havea row of 14 holes of 1. 5 mm diameter at 12.5 mmcentres arranged so that the gas jets issue at anangle of 45 below the horizontal.
3.Aburner carriage consisting of a movablecolumn which incorporates a 10 mm On x 1 mmwall stainless steel tube terminated by athreaded boss to which the various burners canbe fixed.
4.A length of 5 mm internal diameter hose not greater than 3.0 m in length to connect the flowmeters to the burner carriage via a gas cock mounted on the carriage.
5.Test frame. A horizontal steel platform to whicha sliding burner carriage and burner tube areattached. At one end of the platform, means shall beprovided to maintain the specimen holder in avertical position.
6.Specimen holder. The vertical specimen holdershall be capable of accommodating the largest size ofspecimen Specimens shall be gripped at intervalsalong both vertical edges.
For narrower specimens, holders may be designed tofit within the widest holder in order to provide acommon position for testing.
7.Burner carriage and tube. The ignition source shall be mounted on a burner support tube fitted to the burner carriage(see Figure 1). The tube shall be equipped with means to allow vertical adjustment of the ignition source position as required by the various tests. The burner carriage shall be designed in such a way that the distance between the burner and the specimen is obtained accurately. reproducibly and automatically and manufactured so that the ignition source can be brought into the prescribed position smoothly and within 1s.
8.A clamp used to fix the soft wood。
9.Draught shields. Draught shields of 9 mm thicknon-combustible board, triangular in shape, with abase of approximately 500 mm andapproximately 750 mm in height shall be providedfor use with ignition sources A. B and C.
