ISO 11839:2010 pdf free download.Machinery for forestry — Glazing and panel materials used in operator enclosures for protection against thrown sawteeth — Test method and performance criteria.
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 hazards 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 enclosures can be appropriately selected to provide operator protection based upon this International tandard. Although surfaces meeting the criteria given in this International Standard might not give protection inder all conceivable circumstances in which the machine could be mpacted by thrown sawteeth, it is expected that protection against sawteeth thrown from circular saws will be provided under normal operating conditions.
ISO 11839:2010 specifies test procedures and performance requirements 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 unique to these cutting devices.
3.2 Test samples and mounting
3.2.1 Test samples shall be representative of the commercial specification of the given product material.Appropriate 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 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.
4 Performance requirements
panel material is deemed to have failed if the test projectile and/or panel fragments impact the indicator panel.
All samples shall pass the test in order for the material to be classified 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.
