Good Afternoon Mike, For the record, there is no lighting requirement in J-STD-001 (the word should is used in the text). Although the guideline of 1000 lm/m2 seems high, it is the minimum level of illumination in which operators and inspectors should be expected to perform their tasks. You may need to check with your plant safety department and OSHA regulations for other requirements. Steve Sauer Mfg Engineer Northrop Grumman, Xetron -----Original Message----- From: WEEKES, MICHAEL HS-SNS J STD 001 calls out 1000 lumens/m sq. - this seems awfully bright - is this for just repair only or for plant lighting in general - I thought 100 lumens was pretty bright. --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
