| 7 | 1 Scope 1.1 This part of ISO 6916 classifies flexible cellular rubber products known as sponge and expanded rubber. The base material us… 1.2 This part of ISO 6916 does not apply to latex foam rubbers, shoe soling or other similar micro-cellular products, ebonite ce… 1.3 Two types are specified, as follows: 1.4 Attention is drawn to the fact that most extruded or moulded shapes are of sizes too small for cutting standard test pieces…. 2 Normative references 3 Classification (types, classes, grades and suffixes) 3.1 Types 3.2 Classes |
| 8 | 3.3 Grades 3.4 Suffix letters 3.5 Suffix numbers a) 1A2C1F1: This is an open-cell, non-oil-resistant material, firmness 35,1 kPa to 65 kPa, compression set at basic level, ozone-resistant to 25 pphm, and low-temperature-resistant to – 40 ˚C. b) 1C3B1C1F2: This is an open-cell material, oil-resistant at the medium swell level, firmness 65,1 kPa to 95 kpa, compression set 25 % max., ozone-resistant to 25 pphm, and low-temperature-resistant to – 55 ˚C 4 Material and workmanship 4.1 Cellular rubbers produced to this part of ISO 6916 shall be manufactured from natural rubber, synthetic rubber or reclaimed … 4.2 In permitting choice in the use of materials, it is not intended to imply that the resulting different rubber materials are … 5 Physical properties 6 Methods of test 6.1 Unless specifically stated otherwise, all tests shall be carried out in accordance with the methods specified in the annexes to this part of ISO 6916. 6.2 Test pieces shall not be tested for at least 72 h after manufacture. Prior to test, the test pieces shall be stored for at l… 6.3 When 23 ˚C ± 2 ˚C or the phrase “standard temperature” is stated in this document, it shall be taken to mean that the standard temperatures of 23 ˚C ± 2 ˚C or 27 ˚C ± 2 ˚C may be used when appropriate !(see ISO 23529).” 7 Dimensional tolerances |
| 9 | Table 1 – Physical requirements for cellular rubbers, type 1, open-cell (sponge) rubber a If, after ageing, this grade still falls within the compression-deflection requirement of 2,5 kPa to 15 kPa, it shall be considered acceptable even though the change from the original value is greater that ± 20 %. |
| 10 | Table 2 – Physical requirements for cellular rubbers, type 2, closed-cell (expanded) rubber a For cellular materials with densities not exceeding 160 kg/m3, the value of water absorption allowed is 10 % max. by mass. For densities greater than 160 kg/m3, the maximum permitted value of water absorption is 5 % by mass. b This test (annex F) of mass change in liquid B is used in place of the usual oil resistance test of volume change in No. 3 oil… |

The manufacturer shall afford the inspector all reasonable facilities for tests and inspection. 8.2 The purchaser may carry out the tests and inspections to govern acceptance or rejection of the material at his own laboratory or elsewhere. Such tests and inspections shall be made not later than 15 days after receipt of the material. 8.3 All samples for testing, provided as specified in clause 11, shall be visually inspected to determine compliance with the material, workmanship and colour requirements. 8.4 Any material that fails in one or more of the test requirements may be retested. For this purpose, two additional tests shall be made for the requirement in which failure occurred. Failure of either of the retests shall be cause for final rejection. 8.5 Rejected material shall be disposed of as directed by the manufacturer. 9 Packaging and marking 10 Sampling 10.1 When possible, the finished manufactured product shall be used for the tests specified. 10.2 When it is necessary or advisable to obtain test pieces from the article, as in those cases where the entire sample is not … 11 Test pieces and sheets 11.1 Test pieces |
| 14 | 11.2 Test sheets 11.2.1 Standard test sheets of all types of cellular rubber shall be pieces 150 mm ± 5 mm square and 12,5 mm ± 5 mm in thickness… 11.2.2 When specially prepared standard test sheets of sponge rubber are required, they shall be made using the frame shown in F… 11.2.3 When specially prepared standard test sheets of expanded rubber are required, the final stage of cure shall be done using… 12 Measurement of test-piece dimensions |
