Summary: This standard specifies the permanent and temporary (such as maintenance) is used to enclose the work area of laser processing machine for laser laser shield and shield requirements. This standard applies to include visual transparent screens and windows, flat, laser curtain and the wall, including a shield for all components. Optical path components, shutter and processing areas are not completely enclosed laser product requirements contained in the protective cover in GB 7247. 1. This standard also pointed out: a) how to assess and regulate laser shield protective nature, b) how to choose a laser shield.

Foreword

This standard is equivalent to using the International Electrotechnical Commission IEC 60825-4.2006 "Safety of laser products --- Part 4. Laser shield" Only editorial changes. This standard is GB 18151-2000 amendments. This standard compared with GB 18151-2000, the main changes are as follows. --- By the mandatory standards to voluntary standards; --- Body consists of 3 to 5; --- Appendix consists of 3 to 6; --- Illustrated by the 9 to 32; --- An increase of two forms; --- Canceled IEC foreword; 1.3.18 --- deleted, because the provision is included in the GB 7247.1; --- Correct an error. C. 1FEL and PEL difference. the "maximum" should be "minimum"; --- Fixed D. 2 two inappropriate wording. ● laser beam perpendicular to the sample surface is irradiated, the "vertical" to "approximately perpendicular"; ● sample temperature generated by the laser irradiation, the "temperature" to "rise." The Standard Appendix A, Appendix B, Appendix C, Appendix D, Annex E and Annex F is informative appendix. This standard was proposed by the State Administration of Work Safety. This standard produced by the National Standardization Technical Committee on Security. This standard was drafted. China Institute of Metrology. The main drafters of this standard. Lvzheng, red horse. This standard was first released in July 2000. GB/T 18151-2008/IEC 60825-4.2006

Introduction

Style shield issue shortest time termination signal. 3.2 It is designed to automatically terminate the laser radiation signal active shield the surface exposed to excessive laser irradiation emitted from the front. 3.3 As a safety control system, a laser shield portion. When the front surface being above the Class 1 AEL laser radiation, can produce Generate a signal to terminate the laser radiation. 3.4 Under fault conditions can be expected to estimate the maximum amount of laser irradiation before maintenance and inspection during laser shield that can be subjected to the surface. 3.5 Laser shield surface exposed to laser radiation.
