TBS/CDC10 (6437) P3 DRAFT TANZANIA STANDARD TBS/CDC-10 (6437) P3 THERMAL PAPER ROLLS — SPECIFICATION TANZANIA BUREAU OF STANDARDS © TBS 2019 All right Reserved First Edition 2019 TBS/CDC10(6437) P3 0 Foreword This Draft Tanzania Standard is being developed by Stationery and Paper Products Technical Committee under supervision of the Chemical Division Standards Committee and it is in accordance with the procedures of the Bureau. This Draft Tanzania Standard is the first edition of specification for thermal paper rolls. It specifies requirements for materials, types and sizes. Thermal paper is mostly used in Electronic Fiscal Printers (EFP) at point of sales (POS) such as restaurants, hotels, gas stations, supermarkets, and for labels, gaming, ticket & tags and other applications of similar nature. This Draft Tanzania Standard has been prepared with assistance drawn from the following documents: CKS 612, Paper for offset lithographic printing specification, Published by South African Bureau of Standards. BS EN 12858, Paper – Printing and business paper -requirements for continuous stationery. For the purpose of deciding whether a particular requirement of this Tanzania Standard is complied with, the final value observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with TZS 4 (see clause 2). © TBS 2019 - All rights reserved First Edition 2009 TBS/CDC10(6437) P3 DRAFT TANZANIA STANDARD TBS/CDC 10 (6437) P3 Thermal paper rolls – Specification 1 Scope This Draft Tanzania Standard specifies the requirements, sampling and methods of test of thermal paper rolls. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

General requirements 4.1.1 The base paper shall be manufactured from bleached chemically processed cellulose fibres or recycled fibres (or both) or any other material that will ensure compliance with the requirements given in Table 1. 4.1.2 The paper shall be of type 1, type 2, type 3, type 4, type 5, type 6 or type 7 as specified by the supplier. 4.1.3 The thermal paper shall be capable to withstand temperature between 100C to 600C. It shall be coated on one side or both sides with a heat sensitive coating material. 4.1.4 The colour of the base paper and of the coating shall be an acceptable white unless otherwise specified. 4.1.5 The papers shall be free from tears, holes, dust, wood splinters, blemishes, slime spots, creases and other visible defects and shall be uniform in texture. 4.1.6 The paper shall be machine finished on both sides and shall be reasonably free from all defects specified in clause 4.1.5 that may impair its serviceability. 4.1.7 The thermal paper shall be heat, moisture and light resistance and shall comply also with requirements set out in table 1. 4.2 Specific requirements 4.2.1 The physical and chemical properties of thermal paper rolls shall comply with the requirements set out in Table 1. 4.2.2 The type of thermal paper rolls shall be such that optical density, image density and image life under proper storage conditions are visible for 3 years minimum without disappearing.
