1 EAST AFRICAN STANDARD Comb foundation sheets Specification EAST AFRICAN COMMUNITY CD/K/656:2010 ICS EAC 2010 First Edition 2010

2 Foreword Development of the East African Standards has been necessitated by the need for harmonizing requirements governing quality of products and services in East Africa. It is envisaged that through harmonized standardization, trade barriers which are encountered when goods and services are exchanged within the Community will be removed. In order to meet the above objectives, the EAC Partner States have enacted an East African Standardization, Quality Assurance, Metrology and Test Act, 2006 (EAC SQMT Act, 2006) to make provisions for ensuring standardization, quality assurance, metrology and testing of products produced or originating in a third country and traded in the Community in order to facilitate industrial development and trade as well as helping to protect the health and safety of society and the environment in the Community. East African Standards are formulated in accordance with the procedures established by the East African Standards Committee. The East African Standards Committee is established under the provisions of Article 4 of the EAC SQMT Act, The Committee is composed of representatives of the National Standards Bodies in Partner States, together with the representatives from the private sectors and consumer organizations. Draft East African Standards are circulated to stakeholders through the National Standards Bodies in the Partner States. The comments received are discussed and incorporated before finalization of standards, in accordance with the procedures of the Community. Article 15(1) of the EAC SQMT Act, 2006 provides that Within six months of the declaration of an East African Standard, the Partner States shall adopt, without deviation from the approved text of the standard, the East African Standard as a national standard and withdraw any existing national standard with similar scope and purpose. East African Standards are subject to review, to keep pace with technological advances. Users of the East African Standards are therefore expected to ensure that they always have the latest versions of the standards they are implementing.

3 Introduction CD/K/656:2010 Comb foundation sheets are made of pure beeswax embossed with the bases and the beginning of the cell walls and cells of comb of the honey-bee. These sheets form the base midrib or foundation of the honey comb without the superstructure of the cells. They are inserted in the frames, which are placed in beehives, on which the honey-bees complete their combs. In the preparation of this East African Standard, the following sources were consulted extensively: IS 2072:1977(R2004), Specification for Comb Foundation Sheets Codex Alimentarius website: USDA Foreign Agricultural Service website: USDA Agricultural Marketing Service website: USDA Plant Inspectorate Service website: European Union: Assistance derived from these sources is hereby acknowledged.

Table 1 Size of the cells of comb foundation sheets S/ No. REGION Number of cells Length in mm (1) (2) (3) (4) i) Higher mountainous regions ii) Moderately hilly regions iii) Savanna conditions iv) Coastal regions The mass of a comb foundation sheet per 100 cm 2 shall be between 6 and 7 g. 2 EAC 2010 All rights reserved

7 6.3 The cell embossings shall be deep and their sides shall,have clear and raised edges. 7 Sampling The method for drawing representative samples of the sheets and criteria for conformity shall be as prescribed in Annex A. 8 Packing and marking 8.1 Packing Unless otherwise agreed to between the purchaser and the supplier, the comb foundation sheets 5, 10, 25, 50 or 100 in number shall be wrapped in grease-proof paper of a suitable plastic sheet and like polyethylene and packed in a suitable container. Each sheet shall be separated by a ceilophane or trace paper to avoid sticking. The sheets should be stored in a clean place so as to avoid any possible contamination by insecticides and chemicals toxic to the honey-bees. 8.2 Marking Each container shall be suitably marked with the following information: a) Name of the material; b) Name of the manufacturer, or dealer; c) Batch or code number; and d) Net mass in g Each container may also be marked with a Certification Mark.

10 Annex A (normative) Sampling of comb foundation sheets A.1 Precaution on sampling A.1.1 In drawing, storing and handling samples, the following precautions and directions shall be observed: a) While drawing samples, care shall be taken to handle the sheets gently so as to avoid breaking and spoiling the cell-structure. b) Samples shall be kept in a clean place so as to avoid any possible contamination. c) Samples shall be stored in air-tight wooden box and kept in a cool and dry place. The conditions of storage shall be such that they do not unduly affect the quality of the material. A.2 Scale of sampling A.2.1 Lot In any consignment, all the containers of the same size and from the same batch of manufacture shall constitute a lot. A Samples shall be tested for each lot for ascertaining conformity of the material to the requirements of this specification. A.2.2 The number of containers to be selected from a lot shall depend on the size of the lot and shall be in accordance with col 1 and 2 of Table 2. A.2.3 The containers to be selected for sampling shall be chosen at random from the lot and for this purpose random number tables shall be used. In case such tables are not available the following procedure may be adopted. Starting from any container, count them as 1, 2, 3, etc, up to r and so on in a systematic manner. Every rth container thus counted shall be withdrawn; r being the integral part of N/n where N is the total number of containers in the lot, and n the number of containers to be selected. Table 2 Number of containers to be selected for sampling Lot size (N) Number of containers to be selected (n) 2 to to to to to and over 10 A.2.4 Test samples From each of the containers selected as in A.2.2, draw at random, one comb foundation sheet for containers of size less than 25 and two comb foundation sheets for containers of size greater than 25. Each sheet shall constitute a test sample. A.3 Number of tests Tests for the determination of various characteristics, as specified in Clauses 5 and 6 shall be made on each of the test samples (see A.2.4). A.4 Criteria for conformity A lot shall be considered as conforming to this specification if each of the test results satisfied the corresponding requirements as specified in Clauses 5 and 6. 6 EAC 2010 All rights reserved
