Instructions for Use – the New ISO 20607

Instruc­tions are one of the basic items that users expect to get when they pur­chase a product, and yet these import­ant doc­u­ments are often poorly writ­ten, badly trans­lated, and incom­plete. Key product fea­tures are badly described, and inform­a­tion on fea­tures, set­tings and haz­ards may be absent. All of this des­pite the fact that the min­im­um require­ments…

This entry is part 1 of 3 in the series Safety Labels

Machinery Safety Labels The third level of the Hier­archy of Con­trols is Inform­a­tion for Use.

This art­icle was updated 2019-07-24. Ed. Devel­op­ing the Safety Require­ment Spe­cific­a­tion The Safety Require­ment Spe­cific­a­tion sounds pretty heavy, but actu­ally, it is just a big name for a way to organ­ize the inform­a­tion you need to have to ana­lyze and design the safety sys­tems for your machinery. Note that I am assum­ing that you are doing this in…

Shocked and Amazed by Brexit This morn­ing I am shocked and amazed to learn that one of the founders of the European Uni­on has chosen to leave that Uni­on. Join­ing the EEC in 1973, the UK and oth­er European coun­tries moved toward the form­a­tion of the EU, first as an eco­nom­ic treaty, and even­tu­ally as a polit­ic­al…

New Directions in Plastics Machinery

Canada’s Par­ti­cip­a­tion in ISO TC 270 In Feb­ru­ary of 2016, Canada formed the SCC Mir­ror Com­mit­tee (SMC) to ISO TC 270, Rub­ber and Plastics Machinery. This inter­na­tion­al tech­nic­al com­mit­tee is cur­rently devel­op­ing ISO 20430, the first inter­na­tion­al plastic injec­tion mould­ing machine stand­ard.

Testing Emergency Stop Systems

This entry is part 11 of 16 in the series Emer­gency Stop

I’ve had a num­ber of ques­tions from read­ers regard­ing test­ing of emer­gency stop sys­tems, and par­tic­u­larly with the fre­quency of test­ing.
