8、 Foreword This Subsection of BS1133 which has been prepared under the direction of the Packaging and Freight Containers Standards Policy Committee, supersedes clauses1 to12 of BS1133-10:1966. BS1133-10:1966 is withdrawn. BS1133 was originally issued in December1943, primarily to give guidance on the

9、 packaging of Service and other Government supplies. In practice, however, the code was used not only by Government departments and contractors, but also by civilian packers and accordingly it was amended to suit commercial requirements. The Parts were later issued separately and new Sections were a

10、dded as necessary. Since Section10 covers many different types of packaging it was decided to subdivide it into a number of separately published Subsections. This Subsection, Subsection10.1, provides information on tins and cans made from tinplate and aluminium. The packaging code now consists of th

11、e following Sections all of which are published separately with the exception of Sections1 to 3 which are published in one volume. Sections1 to3: Introduction to packaging; Section4: Mechanical aids in package handling; Section5: Protection against spoilage of packages and their contents by micro-or

12、ganisms, insects, mites and rodents; Section6: Temporary protection of metal surfaces against corrosion (during transport and storage); Section7: Paper and board wrappers, bags and containers; Subsection7.1: Wrapping papers; Subsection7.2: Bags and envelopes; Subsection7.3: Cartons and boxes; Subsec

16、ker and veneer baskets” and Section20 “Packaging for air freight excluding livestock” were withdrawn as obsolete. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a Bri

17、tish Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi toiv, pages1to14, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments inco

18、rporated. This will be indicated in the amendment table on the inside front cover.iv blankBS1133-10.1:1990 BSI 07-1999 1 1 Scope This Subsection of BS1133 provides basic information on the various types of tins and cans. NOTE 1British Standards relevant to tins and cans are listed in Appendix A. NOT

19、E 2The titles of the publications referred to in this standard are listed on the inside back cover. 2 Definitions For the purposes of this Subsection of BS1133 the definitions given in BS3130-4 and BS6966-1 and BS6966-2 apply. 3 General Tins and cans form one type of light gauge metal containers, wh

20、ich are defined as rigid containers made of metal with a maximum nominal material thickness of0.49mm. In general tins and cans are made from material no greater than0.33mm thick and have a maximum capacity of10litres 1) . The customary distinction between the use of the word “can” for food container

21、s and “tin” for other containers is not universal and for all practical purposes the two words are synonymous. There are three distinct groups of containers: a) open-top cans; b) general use cans or tins; c) aerosol cans. Tins and cans can readily be fabricated in various shapes and sizes. They are

22、light for economical handling; readily opened and when required re-closed; impervious to air, light and moisture and can be decorated for appearance and product protection. They are inherently strong and, when manufactured in the appropriate material thickness, give adequate protection to their cont

23、ents. Suppliers of dangerous goods need to be aware of statutory and international requirements relevant to the journey to be undertaken. Tins and cans intended to contain substances or articles which are classified as dangerous for transport should either: 1) bear the appropriate UN certification m

24、arking; or 2) possess the physical attributes set out in the relevant regulations and/or supporting approved codes of practice. BS1133-1 to BS1133-3 contain more information on the transport of dangerous goods. 4 Materials 4.1 General Tinplate (a term used in this standard to cover the various forms

25、 of tin mill products) and aluminium (together with certain of its alloys) are the basic materials used in the manufacture of cans. Under normal conditions of storage and use, these materials are suitable for surface treatments such as lacquering and printing. In the appropriate quality they are sui

26、table for shaping operations and assembly work. Shaping operations include stamping, drawing, ironing and bending. Aluminium may also be extruded. Assembly work covers the mechanical forming of joints, which may be untreated or treated with adhesives or leak resistant gaskets. Tinplate can be solder

27、ed or welded. 4.2 Tinplate 4.2.1 General There are three basic tin mill products; the word “tinplate” is commonly used as a generic term to include all three although this is not strictly correct. The base material is common to all three products; a continuous coil of low carbon steel which is rolle

28、d to the required thickness. After heat treatment (annealing) and, if required, surface treatment, the material is available in coil form or cut into individual sheets. The three products are as follows. a) Electrolytic tinplate: the base material is coated with tin applied by electrodeposition. b)

29、Electrolytic chromium/chromium oxide coated steel (ECCS): the base material is electroplated with a chromium/chromium oxide coating. c) Blackplate: the base material is not coated but the surface may be oiled or otherwise treated. The choice of material is dependent on technical and economic require

30、ments. Each of these products is available in two types of base material. 1) Single reduced (SR) tin mill products which have a base material that has been reduced to the desired thickness by cold reduction in a cold reduction mill and subsequently annealed and temper rolled. 2) Double reduced (DR)

31、tin mill products which have a base material that has had a second cold reduction after annealing. 1) Litres are denoted by L throughout this standard.BS1133-10.1:1990 2 BSI 07-1999 The thickness range of the products is from0.16mm to0.49mm, and material is normally available in0.005mm thickness int

32、ervals from0.17mm to0.41mm. DR material is available up to0.27mm and SR material is only available below0.20mm by special arrangement. Material is sold by area, and the unit of area is100 m 2known as a “SITA” (system international tinplate area). 4.2.2 Electrolytic tinplate Electrolytic tinplate can

33、 be produced with an equal amount of tin coating on each surface or with a differential coating. The designation system for electrolytic tinplate indicates the mass of coating on each surface and whether the material is equally or differentially coated. For example E2.8/2.8 is an equally coated tinp

34、late having2.8g/m 2on each surface. D5.6/2.8 is a differentially coated electrolytic tinplate having5.6 g/m 2on one surface and2.8g/m 2on the other. The coating masses most frequently employed are listed in Table 1. There are four commercially recognized surface finishes: a) stone finish: a bright s

35、urface characterized by a directional surface pattern; b) bright finish: achieved by using highly polished rolls; provides a reflective base for decoration; c) matt finish: a surface with low reflectivity, thus not requiring a dense base coat of colour in decorative systems; d) silver finish: a lust

36、rous surface on a roughened base material. 4.2.3 ECCS The base material has a coating with a duplex structure consisting of a layer of chromium metal adjacent to the steel base material, with a chromium oxide layer above it. There is a limited number of variants. The surface is highly susceptible to

37、 abrasion by tooling unless protected, for example by lacquer or decoration. 4.2.4 Blackplate A material which when produced, initially has a bright steel appearance, being the same base material used for electrolytic tinplate and ECCS. As the surface may be unprotected by oil or other coating this

38、material is very susceptible to atmospheric corrosion. Great care, therefore, should be taken when handling and warehousing to prevent sweating and rusting and the plate should be used or surface treated, for example by lacquering or printing, as soon after delivery as possible. Table 1 Electrolytic

39、 tinplate coating masses Blackplate is sold in unassorted quality only, i.e.ungraded with some minor visible imperfections. British Standards relating to tinplate materials are listed in Appendix A, for information. 4.3 Aluminium Aluminium and aluminium alloys are both covered by the term “aluminium

40、”. The materials commonly used for the production of tins and cans are listed in Table 2. Sheets and coils are specified by size and thickness but are marketed by weight (mass). Thicknesses are available covering the full container range and additional thicknesses down to light gauge foil for diaphr

41、agm closures. Aluminium has a high chemical resistance to some products but is vulnerable to corrosion by others. It can however be surface protected by lacquering or printing using the same processes as applied to tinplate. Aluminium should not be contrasted with tinplate but rather should be consi

42、dered as having its own characteristics, which include the following. a) It is non rusting. b) It is available in light gauges for tamper proof closure systems. c) Its strength characteristics make it suitable for roll-on closures (closures which are threaded after assembly). d) Its ductility is an

43、aid to the creation of weakened areas on “easy open ends”. British Standards relating to aluminium and aluminium alloys are listed in Appendix A, for information.

All tinplate and aluminium scrap arising from the container manufacturing process i

45、s recycled, involving significant quantities of material, particularly when round blanks are cut from rectangular sheets, where there could otherwise be up to20% wastage. Used containers are also being recycled in increasing quantities with extraction from domestic waste and consumer aided collectio

46、n both being used in the UK to promote recycling. Steel cans are recycled both by consumer collection and by magnetic extraction from domestic refuse, a relatively low cost process allowing economic recycling. The steel industry encourages can extraction from domestic waste and uses the steel scrap

47、to make new steel products. The relatively low cost of re-smelting, compared with the cost of extraction from the ore, also makes aluminium ideal for recycling. The aluminium industry supports the collection of valuable, used, aluminium beverage containers prior to entry into the waste stream. 5 Bas

48、ic can types 5.1 General Cans are classified by: a) type; b) construction; c) cross section; d) body shape and special features; e) closure or other fitting. 5.2 Can types There are three basic can types as follows: a) Open-top can: a can to which an end is double seamed after filling. This covers t

49、he range of food, beer and beverage containers as well as some others. b) General use can or tin: a container which is sealed after filling with a closure not required to be double seamed. This group covers most of the recloseable containers used for household and chemical products. c) Aerosol can: a non-refillable can intended to contain a product which is dispensed by a pre-stored pressure in a controlled manner through a valve.
