The work of preparing International Standards
18、 is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take p
19、art in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to
20、 prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility t

ISO 11839 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 15, Machinery
22、for forestry. BS ISO 11839:2010ISO 11839:2010(E) iv ISO 2010 All rights reservedIntroduction Forestry machines that use circular saws with replaceable sawteeth can expose the operator to the hazard of thrown sawteeth. Operator enclosures on forestry machinery provide protection from a variety of haz
23、ards by interposing a system of structural members and panel materials between the operator and potential hazards (see, for example, ISO 8083 for falling objects or ISO 8084 for poking hazards). When there is a hazard from circular-saw thrown sawteeth, panel and glazing materials used in operator en
24、closures can be appropriately selected to provide operator protection based upon this International Standard. Although surfaces meeting the criteria given in this International Standard might not give protection under all conceivable circumstances in which the machine could be impacted by thrown saw
25、teeth, it is expected that protection against sawteeth thrown from circular saws will be provided under normal operating conditions.

26、for protection against thrown sawteeth Test method and performance criteria CAUTION Some of the tests specified in this International Standard involve the use of processes which could lead to a hazardous situation. 1 Scope This International Standard specifies test procedures and performance require
27、ments for determining the protective ability of panel materials used in forestry-machinery operator enclosures intended to protect the operator against sawteeth thrown by circular-saw components. This particular type of hazard is specifically defined by the size and velocity of the sawteeth and is u
28、nique to these cutting devices. This International Standard is applicable to panel materials for forestry machines defined in ISO 6814 that include an integrated or attached circular sawing device, controlled or powered by the primary machine (e.g. topping saws, felling saws or bucking saws). It doe
29、s not address protection from chain-shot hazards (see ISO 11837). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced docum

ISO 6814, Machinery for forestry Mobile and self-propelled machinery Terms, definitions and classification 3 Tests 3.1 Test equipment 3.1.1 Projectile launcher, capable of propelling the specified test projectiles at the required velocities. The launcher shall
31、 have a controllable means of adjusting velocity. The launcher shall also have a means of orienting and directing the test projectile in relatively linear motion with the cutting surface towards the target. The test projectile may be supported in the launcher by a test projectile holder (i.e. a sabo
32、t). Such a test projectile holder should be less than 10 % of the mass of the tooth projectile being propelled, and any impact of the holder on the test panel shall be clearly inconsequential to the test result (see Figure 1). 3.1.2 Test projectile (F1), consisting of a representative four-pointed s
33、awtooth, 300 g 5 g, with a cutting surface 50 mm 1 mm square (see Figure 2). 3.1.3 Test projectile (F2), consisting of a representative, four-pointed sawtooth, 800 g 5 g, with a cutting surface 60 mm 1 mm square (see Figure 2).

35、 assembly perpendicular to the line of motion of the test projectile, with the target surface 3 000 mm 50 mm from the muzzle of the launcher. 3.1.7 Means of measuring test projectile velocity to an accuracy of 2 m/s. 3.1.8 Means of measuring panel surface temperature to an accuracy of 1 C. 3.1.9 Con
36、tainment structure surrounding the test projectile line of motion, target assembly and indicator panel to provide suitable protection for test personnel. 3.2 Test samples and mounting 3.2.1 Test samples shall be representative of the commercial specification of the given product material. Appropriat
37、e material properties shall be determined and reported to verify test conditions. 3.2.2 Test samples shall be mounted onto the target panel opening using the manufacturers specified attachment methods. The exception to this are test samples from materials that are typically attached using permanent
38、methods such as welding; these may be attached to a separate frame that is then bolted to the target panel opening. Mounting details shall be recorded and reported. 3.3 Test method 3.3.1 Five samples shall be tested at low temperature and five samples at room temperature. Each sample shall be impact
39、ed once. The low-temperature samples shall be conditioned for 3 h prior to testing with the impact side exposed to 32 C 3 C, and the operator side shall be exposed to a room temperature of +22 C 3 C. The room temperature samples shall be conditioned for 3 h at +22 C 3 C. 3.3.2 Five samples of non-me
40、tallic materials shall also be high-temperature-tested at +49 C 3 C. Samples shall be conditioned at the elevated temperature for a minimum of 3 h prior to testing. 3.3.3 Each material shall be tested at the appropriate energy level, namely either 1 084 J to 1 311 J for F1, or 4 840 J to 5 856 J for
41、 F2. The selection of the energy level shall be based on consideration of the type of thrown sawteeth hazard the material will face, in accordance with Annex B. 3.3.4 The F1 test projectile shall impact the target at a velocity of 85 m/s to 94 m/s. The F2 test projectile shall impact the target at a
42、 velocity of 110 m/s to 121 m/s. 3.3.5 If the velocity of the test projectile is less than the minimum specified velocity and the sample does not fail, the test shall be repeated. If the velocity of the test projectile is less than the minimum velocity and the sample fails, the test result (failure)
43、 is accepted. If the velocity of the test projectile is more than the maximum velocity, and the test sample passes, the test result (pass) is considered acceptable. 3.3.6 The test projectile shall impact the panel with the cutting surface forward in at least three of the sample impacts and within th
44、e target opening.

All samples shall pass the test in order for the material to be classifi
45、ed at the tested level. 5 Reporting results The results of the tests shall be reported using a test report whose content is in accordance with Annex A.
