 Table 3 — Thickness of plate (prior to zinc coating)  
 
4.3 Construction  
4.3.1  Upper part of the bin  
The rim of bins shall have a bead, of external diameter 8 m m ± 2 mm that is such that after the zinc coating has 
been applied, the width of the gap between the bead and the side of the bin does not exceed 1 mm. There shall 
be a projection rolled in the side of the bin below the bead, positioned and of the dimensio ns as shown in Figure 
3. The handles shall be diametrically opposite to each other in a 15 mm interval.  
4.3.2  Bottom (refer to Figure 4)  
The radius of curvature of the bottom (where it meets the side) shall be at least 6 mm. The bottom shall have a 
reinforcing hoop whose ends are joined by welding. The hoop (and its attachment to the bin) shall be such that 
the lower edge of the hoop does not deviate from plane by more than 5 mm and that the clearance between the 
bottom of the bin and the plane of the lower edge  of the hoop is at least 8 mm.  
 
4.3.3  Seams  
Seams shall be either welded or folded. There shall be one seam only in the side -wall and the seam between 
the side and bottom of the bin shall not extend above the upper edge of the bottom hoop by more than 13 mm 
(Refer to  Figure 4).  
4.3.4  Nesting  
Each bin shall have a positive stop (such as afforded by the handles) that is such that when two bins of the 
same size are nested together and are then inverted, the inner bin falls out under its own weight.  
4.3.5  Lids 
The lid shall be made of one piece of sheet to which the handle is secured. The edge of the skirt shall have a 
bead, of external diameter 8 mm ± 2 mm that is such that, after the zinc coating has been applied, the width of 
the gap between the bead and the surface of the skirt does not exceed 1 mm.  
DRS 505: 2022  
5                ©RSB 2022  - All rights reserved  
 4.3.6  Workmanship  
The internal surfaces of the bin shall not be corrugated and shall be free from surface irregularities of depth or 
height exceeding 2 mm (other than those caused by the markings required in terms of section 4 , by rivet heads, 
by seams, and by the rolled projection specified in 4.3.1).  
4.3.7  Finish  
Each bin and lid shall be completely covered by a zinc coating that complies with the requirements of RS ISO 
1461 and ASTM A653  for zinc coatings.  
4.4 Strength  
4.4.1  Rigidity of the  bottom  
After a bin has been tested in accordance with 6.2, the clearance between the bottom of the bin and the plane 
of the lower edge of the bottom reinforcing hoop shall be at least 8 mm.  
4.4.2  Resistance to edge drops  
After a bin has been tested in accordanc e with 6.3:  
a) when the sand is removed and the bin is half -filled with water, the rate of any leakage of the water  shall not 
exceed half a litre in 2 min ; and 
b) there shall be no fracture of weld or plate metal other than cracks in welds that extend across less than 
10 % of the greatest length of the weld or across 3 mm, whichever is the lesser.  
4.4.3  Strength of handles  
When a bin is tested in accordance with 5.3, the handles may become bent but there shall be no fracture of a 
weld or tearing of the parent  metal.  
 
5 Test methods  
5.1 Rigidity of the bottom  
Measure the clearance between the bottom of the bin and the plane of the lower edge of the bottom reinforcing 
hoop. Load the bin with sand to the appropriate of the following masses:  
Table 4 — Test methods for the rigidity of bin bottom   
S/N Bin size  
L Gross mass  
kg 
 85 90±1   
©RSB 2022  - All rights reserved                  6 
  57 60±1  
Secure the lid in place and drop the bin, in a vertical position from a height of 300 mm ± 10 mm, ten times onto 
a steel plate (of thickness at least 12 mm and width at least 500 mm) that is superimposed on a plane concrete 
slab of thickness at least 75 mm. Between drops make good sand lost during the previous drop. After ten drops 
re-measure the clearance between the bottom of the bin and the plane of the  lower edge of the bottom hoop . 
5.2 Resistance to edge drops  
Re-load the bin as per 5.1 and so secure the lid on the bin so as to minimize the sand lost in the test. Raise the 
bin by one handle so that the lowest point of the bottom hoop is 1 050 mm ± 15 mm ab ove the plate and allow 
the bin to drop, but prevent the bin from falling over onto either of its handles after contact with the plate. Repeat 
the drop using the other handle, and continue dropping the bin from alternate handles until a total of six drops 
has been made, making good, between drops, sand lost during the previous drop. Then remove the sand from 
the bin, examine it for compliance with 4.4.2(b) and fill it, to half its nominal capacity, with water and check for 
compliance with 4.4.2(a).  
 
5.3 Test f or strength of handles  
5.3.1  Bin handles  
After subjecting the bin to the tests given in 5.1 and 5.2, secure it (empty) in an upright position and so drop a 
flat-bottomed mass of 9 kg from a height of 300 mm ± 10 mm that it strikes the centre of the grip portion of one 
handle of the bin. Invert the bin and secure it in the upside -down position and drop the mass onto the same 
handle in a similar manner as before. Repeat the above drops until a total of 14 drops has been applied, 7 in 
each direction, to one handle. Repeat the test on the other bin handle, and then examine the bin and handles 
for compliance with 4.4.3.  
5.3.2  Lid handles  
Secure the lid, standing on the lower edge of its skirt, with the handle horizontal. Then,  drop the mass used in 
5.4.1 from the sam e height that it strikes the edge of the grip portion of the handle. Rotate the lid and repeat the 
drop onto the other edge of the grip of the handle. Repeat the above drops until a total of 8 drops has been 
applied, 4 to each edge of the handle, and then examine the handle and lid for compliance with 4.4.3.  
 
5.3.3  Tests for zinc coating  
After subjecting a bin to the tests given in 5. 1, 5.2, and 5. 3, cut specimens from the side and bottom of the bin 
and from the lid, and use the relevant methods given in RS ISO 1461  and ASTM A653  to test for compliance 
with 4.3.6.  
6 Marking  
Each steel refuse bin and lid shall be indelibly and legibly marked with the following information:  
a) trademark, n ame or symbol identifying the manufacturer ; DRS 505: 2022  
7                ©RSB 2022  - All rights reserved  
 b) capacity in litres ; 
c) steel grade used to manufacture the refuse bin ; and  
d) dimensions .  
7 Inspection, s ampling and compliance  
7.1 Inspection  
Each item sampled in accordance with 7.2 and 7.3 shall be visually examined and measured for compliance 
with all the relevant requirements with which compli ance is not assessed by testing.  
NOTE  Sampled item means bin and/or lid.  
7.2 Sampling  
Sampling plan (Table 5) shall be used for inspection and testing before acceptance or rejection of single lots 
(consignments). It shall also be used in cases of dispute.  
The following sampling procedure shall be applied in determining whether a lot meets  the requirements of the 
specification. The samples so taken shall be deemed to represent the lot for the respective properties.  
From the lot take n at random , the number of items, or bins, or lids (as relevant), shown in columns 2 and 3 of 
Table 4 relative to the appropriate lot size shown in column 1.  
NOTE The sample for testing may be taken from the inspection sample after it has been inspected.  
7.3 Compliance  
The lot  shall be deemed to comply with the requirements of th is specification , if after inspection and testing of 
the samples taken in accordance with 7. 2, the numbers of defectives found do not exceed the corresponding 
acceptance numbers shown in columns 4 and 5  respectively of Table 5.
