ESTA's Technical Standards Program Announces Three Revision Projects Are Open

Three existing ESTA Technical Standards Program standards have been opened for revision. Materially affected parties are invited to join the Technical Standards Program working groups developing the revisions or to comment in future public reviews. The three revision projects are:

BSR E1.40, Recommendations for the Planning of Theatrical Dust Effects -- The standard is being revised primarily to address deflagration of dust. Other changes include a generalized grouping of types of dusts, editorial changes, and changes to references to Material Safety Data Sheets, which have been replaced by Safety Data Sheets. This is a project of the fog and smoke working group.

BSR E1.41, Recommendations for the Measurement of Entertainment Luminaires Utilizing Solid State Light Sources -- This standard is being opened for revision to specify that the Fidelity Index (Rf) rating as defined in IES TM-30-15, IES Method for Evaluating Light Source Color Rendition, is used for reporting the production of white light of a reported CCT. This is a project of the photometrics working group.

BSR E1.55, Standard for Theatrical Makeup Mirror Lighting -- This standard is being opened for revision to add the Fidelity Index (Rf) rating per IES TM-30-15, IES Method for Evaluating Light Source Color Rendition, as an acceptable rating to meet the requirements for color rendering. This is a project of the photometrics working group.
