As the testing facilities and staff have become adequate to undertakewider responsibilities, various classes of work heretofore carried on by other depart-ments but which logically should form part of the duties of a testing and researchdepartment, have been turned over to this department.

The testing work includesroutine testing, special testing and approval testing. Under routine testing maybe classed: (a) Acceptance tests, made on apparatus or samples of any product purchasedunder specification, from the results of which tests the product isaccepted or rejected. (&) Inspection of engineering materials such as steel, concrete, etc. (c) Control tests for the purpose of obtaining a continuous record of the quality of a product being regularly used. These include such productsas transformer oil, rubber gloves, etc. (d) Standardization and calibration of electrical measuring instruments. 1C20 HYDRO-ELECTRIC POWER COMMISSION 273 Special tests include those for which no standardized method of procedure hasbeen dev
