19、ementary pallet, to retain the gross weight at the limit load (two-thirds of ultimate load) condition for the design rating specified in3.3; c) so that the permanent deformation is acceptable at the ultimate load. 3.2.4 Assembly construction The net assembly shall be constructed so that it adequatel
20、y encompasses the pallet load and attaches to fittings on all four edges of the pallet in accordance with ISO8097. 3.2.5 Hardware 3.2.5.1 The net hardware shall be designed and constructed so that it can be easily operated in confined areas. 3.2.5.2 All hardware shall be securely attached to prevent
21、 it being lost. 3.2.5.3 Free ends that pass through adjusting buckles shall be equipped with stops.

23、itzerland.BSM82:1995 2 BSI 11-1999 3.2.5.4 Provision shall be made to enable the net to be tensioned evenly over the cargo. If a mechanical advantage facility is provided to achieve the tension, the release of the tensile force shall be achieved by an operating force not greater than16%of the tensio
24、ning force and it shall be possible to release the force using a gloved hand. 3.2.5.5 Pallet attachment fittings shall conform with ISO7166. 3.2.6 Net mesh and configuration 3.2.6.1 The net design shall ensure a minimum installation time and shall be of a configuration such as to minimize the possib
25、ility of incorrect installation. 3.2.6.2 The net shall be constructed in such a manner that entanglement during installation and storage is minimized. 3.2.6.3 Nets shall be adequately treated to minimize shrinkage. 3.2.6.4 All netting ends shall be suitably prepared to prevent fraying. 3.2.6.5 The m
26、aterial used for netting shall meet the appropriate regulatory standards for polyamid or polyester and its treatment. If other materials are used, they shall meet equivalent standards for material and treatment. 3.2.6.6 If netting is made from polyamid, polyester or other textile material, considera
27、tion should be given to take account of strength degradation resulting from wear and exposure to ultraviolet radiation. See ISO/TR8647. 3.2.6.7 Nets shall restrain load within the maximum allowable contours. See IATA ULD Technical Manual, 8th edition, specification50/0, Appendix D, or ISO 10046:, Fi
28、gure 7. 3.2.6.8 The net mesh shall be capable of restrainingboxes with dimensions of250mm 300mm 300mm (10in12in 12in). 3.2.7 Reefing adjustment The net shall be constructed so as to provideadjustment in the vertical range from610mm (24in) to a height of3m (118in) or a height appropriate to the aircr
29、aft installation. 3.2.8 Colour The colour of the net material and hardware shall be optional. However, contrasting colours may be used to distinguish net components for simplifying attachment of the net to the pallet. 3.2.9 Special marking In addition to the marking requirements specified in clause6
30、, the net shall be clearly marked to facilitate rigging on the pallet. If the net operation is not omnidirectional, top and bottom, and inside and outside shall be indicated. Character markings or colour coding may be used to facilitate rapid attachment of net fittings to the pallet. 3.2.10 Weight l
31、imits The tare weight of the net assembly shall be kept to a minimum consistent with the requirements and limits of sound design practices. 3.3 Ratings The net shall be designed to restrain the gross weight 3)specified in Table 2 when attached to the pallet according to the appropriate configuration
32、 shown in ISO8097. Table 2 3.4 Performance requirements 3.4.1 The net assembly shall be tested to show compliance with the performance requirements specified in ISO8097. The net configuration shall be tested for each of the load and restraint conditions applicable to that configuration, unless the c
33、ritical combination is beyond doubt, in which case the net need only be tested for the most critical conditions. 3.4.2 Alternatively, compliance with ISO8097may be proven by analytical methods. 3.5 Airworthiness The airworthiness requirements specified in ISO8097shall be applicable. 3) The term “wei
34、ght” is used throughout this International Standard, instead of the correct technical term “mass”, in order to conform to current commercial usage.

See ISO/TR8647. 4.1.2 The structural and operational integrity of thene
36、t shall be maintained at temperatures from 55 C to+70 C (65 F to+160 F). 4.1.3 All components of the net shall be protected against deterioration or loss of strength in service due to weathering, corrosion or other causes where the type of material used requires such protection. 4.1.4 The net shall
37、be designed so that it will withstand handling common to air/land freight terminal and ramp operations. 4.2 Materials and processes 4.2.1 In order to provide for maximum service life, consideration should be given to the materials and processes used in the construction to take into account the extre
38、mely hard usage to which the net will be subjected. All metal parts should be suitably protected against corrosion. All non-metallic materials which are liquid-absorbent should be sealed or treated to prevent liquid absorption. 4.2.2 The materials used shall be flame-resistant in accordance with app
39、ropriate regulatory requirements. 5 Production nets In order to show compliance with its specification standard, commercial inspection, and quality control methods and practices shall be used to ensure that production units are not inferior to the article tested. Where changes are made to production
40、 units and product similarity cannot be clearly established, the first product so changed shall be retested to prove compliance with its specification. 6 Marking requirements All nets covered by this International Standard shall be marked in accordance with the following requirements: The markings s
41、hall be shown on the outside of the net in such a manner that good readability is ensured under all phases of handling. All weights shall be rounded off to the next highest0,5kg or full pound.BSM82:1995 4 BSI 11-1999 Figure 1 Net assembly (typical design pattern optional)BSM82:1995 BSI 11-1999 List
