1.1 This practice covers procedures for calibrating leak artifacts of a specified gas, that may be used for determining the response of leak detectors, or in other situations where a known small flow of gas is required. The purpose of this practice is to establish calibration...
Specifies procedures for determining a sensitivity figure for mass-spectrometer type leak detectors. Two procedures are outlined, one for determining minimum detectable leak rate; the other for determining minimum detectable concentration ratio. Specifically excepted are sensing...
6.1 Test Method A is the most frequently used in leak testing components which are structurally capable of being evacuated to pressures of 0.1 Pa (approximately 10-3 torr). Testing of small components can be correlated to calibrated leaks, and the actual leak rate can be...
1.1 This guide describes standard procedures for using electrical conductance measurement methods to locate leaks in exposed or covered waterproof membranes. 1.2 This guide addresses the need for a general technical description of the current methods and procedures that are used to test and...
5.1 Test Method A-This test method is the most frequently used in leak testing components. Testing of components is correlated to a standard leak, and the actual leak rate is measured. Acceptance is based on the maximum system allowable leakage. For most production needs,...
This European Standard specifies requirements and test methods for the migration of aluminium, antimony, arsenic, barium, boron, cadmium, chromium (III), chromium (VI), cobalt, copper, lead, manganese, mercury, nickel, selenium, strontium, tin, organic tin and zinc from toy materials and from parts...
This report presents technology background and test results on an improved Leak Detection and Control method for application in refineries and petrochemical plants. Smart Leak Detection and Repair (LDAR) focuses on locating and repairing the most significant leaking components,...
5.1 These test methods provide a rapid, simple to apply method to detect small leaks in flexible package seals or walls at the leak rate level of greater than 1 x 10-4 sccs, thus providing a measure of package integrity. Porous barrier film packages made non-porous with an impermeable...
5.1 Leaks in medical device, pharmaceutical, and food packages may result in the ingress of unwanted gases (most commonly oxygen), harmful microbiological, or particulate contaminants. Package leaks may appear as imperfections in the package components themselves or at the seal...
5.1 The measurement of mercaptans in natural gas is important, because mercaptans are often added as odorants to natural gas to provide a warning property. The odor provided by the mercaptan serves to warn consumers (for example, residential use) of natural gas leaks at levels that are well...
This Standard is restricted to refrigeration circuits that provide air-conditioning for the passenger compartments of passenger and commercial vehicles. This Standard includes analytical and physical test procedures to evaluate refrigerant concentration inside the passenger compartment. In the...
6.1 Test Method A is frequently used to test large systems and complex piping installations that can be filled with a trace gas. Helium is normally used. The test method is used to locate leaks but cannot be used to quantify except for approximation. Care must be taken to provide sufficient...
This standard is for estimating the hydraulic properties of a groundwater system by inverse numerical modeling of aquifer pumping tests. Guidance is provided on using a numerical groundwater flow model to simulate an aquifer pumping test (APT) and estimate aquifer hydraulic properties by matching...
6.1 Test Method A is the most frequently used in leak testing components which are structurally capable of being evacuated to pressures of 0.1 Pa (approximately 10−3 torr). Testing of small components can be correlated to calibrated leaks, and the actual leak rate can be...
This practice describes standard procedures for using an electronic scanning system to locate membrane breaches on both horizontal and vertical surfaces to locate potential leaks in exposed roofing and waterproofing membranes. This practice addresses the need for a detailed technical...
