Foreword
All technical contents of this section is mandatory.
"Folding bed by turning the safety requirements and test methods" is divided into two parts.
--- GB/T 26172.2-2010 fold turned against the bed safety requirements and test methods - Part 2. Test Method.
This part is "fold turned against the bed safety requirements and test methods" Part 1.
This partial modification using ISO 10131-1.1997 "Folding bed by turning the safety requirements and testing Part 1. Security requirements" (English
Version). This part of ISO 10131-1.1997 Technical changed compared as follows.
--- increased wood materials, metal materials security requirements (see 4.1.1 and 4.1.2).
This section also made the following editorial changes.
--- with symbols instead of decimal decimal symbol "," ".";
--- Page change;
--- instead of "this International Standard" by "this standard";
--- with "this part of the standard" instead of "in the present section of this International Standard";
--- delete informative overview of elements of international standards (including the cover, foreword and introduction);
--- For ease of reference the second portion of the test method, increasing the number of sub-clause.

Mounting the folded portion of the frame 4.4
4.4.1 folding apparatus should be fastened to the frame of the building or other structure, the product should not loosen during use.
Note. Under normal circumstances, the use of nuts and bolts is better than the use of ordinary wood screws effect.
4.4.2 When tested according to GB/T 26172.2-2010 5.4, it should be no loose fasteners.
4.5 strength and durability
When tested according to GB/T 26172.2-2010 5.6 and the 5.5.1,5.5.2, and the connecting member product or a building structure
He mounting member structure should not loose any damage and affect the product functionality and safety.
4.6 Unintentional closure
When tested according to GB/T 26172.2-2010 5.5.3, collapsible member should not be self-closing, lift from the ground support means
Distance face should not exceed 5mm.

Appendix A
(Normative)
Folding bed mounting position by turning the screw a minimum number of calculation
A.1 select the appropriate material and thickness of the screw mounting position, in order to ensure the tension evenly distributed on all of the mounting screws. Two phases
The distance between adjacent screw should be at least 50mm.
The minimum number of screws A.2 n calculation equation of each wall of the screw used in the fitting point, see Equation (A.1).
n = FhFs
(A.1)
Where.
--- FH strength test load of each mounting position in Newtons (N);
FS --- product installation building frame structures or other nail-holding ability of each screw is provided (the ability to resist the nail is removed), a single
Bit Newtons (N). Nail holding force of the mounting structure of the different sample sizes.
Wherein calculating Fh see formula (A.2).
Fh = 5Fp 100 (A.2)
Where.
FH --- strength test load of each mounting position (not less than 400N), in Newtons (N);
Folding bed --- FP turned on during the opening and closing of the maximum horizontal force acting on each of the mounting points, in Newtons (N).
Maximum force of the folding bed turned on during the opening and closing of each tie point deduction can withstand the measurement shall be calculated or derived. Pull
Force as a positive value, the pressure is set at zero.
