3 Significance And Use
3.1 Table saws with an integral injury mitigation system that responds to a change in capacitance due to spinning blade contact are addressed by the test procedure described herein. Mitigation means not responsive to capacitive contact, non-contact mitigation means and non-spinning blade contact are not addressed.
3.2 The test procedure specifies the mechanical and electrical criteria necessary for repeatable and reliable means of blade contact and depth of cut measurement.
4 Table Saw Sample Preparation
4.1 A table saw test sample is assembled per the manufacturer’s instructions with the exception of the blade guard system. The blade guard system is removed for all tests.
4.2 The manufacturer’s recommended saw blade(s) are used for all tests.
4.3 One table saw is used for all tests. However, a table saw test sample or part thereof may be replaced
with a new sample or part if the original becomes unusable.
5 Laboratory Test Apparatus
5.1 The laboratory test apparatus consists of the following:
a) Linear actuator3 with a minimum travel distance of 500 mm and a travel speed up to 2 m/sec;
b) Human body network (HBN) consisting of a circuit of resistor and capacitor values and configuration as shown in Figure 5.1. Note that Cs capacitance values vary as specified in 7.4.UL RP 3002 pdf download.
