Structure
This section defines the scope of the standard concerning wirebound wooden crates intended for packaging and transport. It includes references to related standards governing timber species and fasteners. Two primary crate styles are described: Style A featuring wirebound crates with intermediate slats, and Style B consisting of upright or wrap-around crates suitable for bulky items. The section also includes material specifications and construction principles to ensure secure packaging.
This segment provides definitions for key terms related to wirebound wooden crates including Style A and Style B crates, intermediate slats, and other structural components. It cross-references applicable standards for timber and fasteners and explains the significance of design elements such as bolting and blocking within crates.
Details on the materials used in wirebound crate construction are covered here, specifying timber species as per relevant codes, steel wire nails conforming to standards, and mild steel wire for binding. The properties and quality requirements for each material type are outlined to ensure durability and functional performance.
This chapter elaborates on the two main crate design styles, their structural features, and suitability for different cargo types. It discusses base configurations, intermediate slat positioning—particularly at approximately 45 degrees for enhanced resistance against distortion—and fastening methods to maintain crate integrity during handling and transit.
Instructions for constructing the crates are provided, including selection between Style A and Style B based on product type, fastening techniques such as bolting or blocking items within the crate, and assembly of tops using nails or staples. Material references and fastening specifications are reiterated to guide proper fabrication.
This section details workmanship criteria for components such as boards, battens, liners, and slats, emphasizing uniform thickness, rectangular sections, squared ends, and smooth finishes. It also describes the arrangement of intermediate slats at an angle near 45 degrees to enhance distortion resistance and structural stability.
Guidelines for marking each completed crate or bundle include the necessity for clear, permanent markings with the manufacturer’s name or trademark, year of production, and package number and size. The marking process supports traceability, quality assurance, and prevents misidentification during handling and storage.
This final section highlights the typical applications of wirebound crates, particularly Style B crates for heavy or delicate items like appliances and transformers. It summarizes securing methods and confirms compliance with material and construction standards to guarantee safe and effective shipment.
Frequently Asked
The standard covers wirebound wooden crates designed primarily for packaging and transportation purposes. It includes different crate types distinguished by their construction and intended use, such as open slatted crates that provide ventilation, closed slatted crates offering enhanced protection, and reinforced crates featuring additional wire bindings for heavier cargo. These crates are designed to balance strength, cost-effectiveness, and ease of handling.
Timber species suitable for these crates are selected from Groups I, II, and III as classified in IS 6662-1972. These groups include durable and strong timber types like Teak, Sal, Sisam (Group I), Mango, Shisham, Neem (Group II), and Pine, Chir, Deodar (Group III). The timber should be properly seasoned to a moisture content of 15% or less, ideally around 10%, to ensure dimensional stability and strength.
Binding wire must be made of mild steel, annealed for flexibility, typically with a diameter ranging from 1.6 to 2.0 millimeters, and possess a minimum tensile strength of 350 N/mm². It is often zinc-coated to resist corrosion. Nails should be mild steel wire nails or box nails, galvanized for durability, generally between 25 to 40 millimeters in length and 1.5 to 2.0 millimeters in diameter. These specifications ensure a secure and long-lasting assembly.
The standard promotes distortion resistance through the incorporation of diagonal slats both on the crate’s base and top. Diagonal members on the top help counteract deformation from stacking loads and external pressures, while diagonal slats on the base can enhance distortion resistance by up to 200%. These braces stiffen the crate structure against racking and twisting forces, thereby maintaining the crate’s shape and protecting its contents.
Each wirebound wooden crate must bear clear and permanent markings that include the manufacturer’s name, initials, or trademark, the year of manufacture, and the package’s number and size. These markings ensure traceability and prevent confusion during storage and transportation, and should be applied legibly either directly on the crate or on securely attached labels.
