ANSI B151.1:2017 pdf download.Safety Requirements for Injection Molding Machines.
The requirements of ANSI B151.1 apply to Horizontal and Vertical Clamp Injection Molding Machines (HCIMMs and VCIMMs) that process plastic materials and inject said material into a mold(s) held closed by the acting clamp.
1MM suppliers and users shall use the risk assessment process in the manufacture, maintenance, and use of the machinery to eliminate or reduce risk.
Deviations from the requirements of ANSI B151.1 shall be based on a documented risk assessment that demonstrates acceptable residual risk.
Safety requirements for the use of ancillary equipment or molds for IMMs are not covered by ANSI B151.1.
1.2 Purpose
The purpose of ANSI B151.1 is to identify and address known hazards to personnel working on, or adjacent to, an 1MM.
1.3 Application
The user shall ensure that the use of an 1MM shall be in conformance with the requirements of clause 4.

3 Definitions
For the purposes of this standard, the following definitions apply:
3.1 alarm: An indication that a failure or misadjustment of a device has occurred.
3.2 anti-repeat: The part of the control system that is designed to limit the 1MM to one cycle even though the actuating mechanism is held in the “operate” position. Anti-repeat requires release of actuating controls before another cycle can be initiated.
3.3 automatic cycle (continuous): A selectable mode of operation of the 1MM which allows it to perform more than one cycle.
3.4 barrel: The cylinder portion of the plasticizing/injection unit within which the material is processed.
3.5 clamp: That portion of the 1MM that holds two halves of a mold and opens and closes the mold.
3.6 coasting: Power-free deceleration to stop motion, including unintentional gravity descent.
3.7 concurrent: Acting in conjunction; used to describe a situation wherein two or more control devices.ANSI B151.1 pdf download.
