EP1227GY: disposable foam earplugs in green/yellow, SNR 37 dB

The EP1227GY is a conical disposable PU foam earplug in green/yellow. It belongs to the EP1227 series and is rolled before insertion and pushed deep into the ear canal.

• Item number: EP1227GY
• Colour: green/yellow
• Attenuation values: SNR 37 dB; H 37, M 35, L 30 dB
• Standard: EN 352-2:2020, PPE category III
• Packaging: 2,000 pairs, 200 per dispenser box
• Use: once, then dispose of

Patterned in green/yellow. These are the same earplugs that are in the EP500SGY wall dispenser and in the EPR1227GY refill bag: anyone using the dispenser at the entrance to the noise area hands out EP1227GY. The dispenser and refill bag have a declaration of conformity of their own with certificate 2777/13330-06/E02-01 of 25 August 2026.

The attenuation values are the same in all colours of the series (SNR 37 dB, H 37, M 35, L 30 dB). Anyone mixing dispenser and loose stock therefore does not need to adapt the selection.

For selection, DGUV Rule 112-194 works with the M value and deducts a real-world deduction: M 35 dB minus 9 dB gives 26 dB. For mid- to high-frequency noise, the EP1227GY then lets through at the ear:

• Noise level 90 dB(A): 64 dB(A) at the ear (Check for overprotection)
• Noise level 95 dB(A): 69 dB(A) at the ear (Check for overprotection)
• Noise level 100 dB(A): 74 dB(A) at the ear (Recommended)
• Noise level 105 dB(A): 79 dB(A) at the ear (Recommended)
• Noise level 110 dB(A): 84 dB(A) at the ear (Not recommended)

At the ear, 70 to 80 dB(A) is recommended. The EP1227GY is therefore in the recommended range for workplace levels of about 96 to 106 dB(A). Below that it attenuates more than necessary and there is a risk of overprotection; above it, the attenuation is no longer enough. For predominantly low-frequency noise the L value applies (30 dB minus 9 dB equals 21 dB): the recommended range is then about 91 to 101 dB(A). Your own levels are calculated by the hearing protection finder; the calculation is shown in Calculating the residual level at the ear.

The EP1227GY is category III PPE under Regulation (EU) 2016/425. EU type-examination certificate 2777/13330-05/E05-02 from SATRA Technology Europe names the item number expressly; it was issued on 29 October 2025 and is valid until 18 October 2029. What such a certificate contains is explained in Reading an EU type-examination certificate.

Whether SATRA Technology Europe is notified for hearing protection can be checked in the European Commission’s NANDO database: the body is listed there under identification number 2777 for “Equipment providing hearing protection” and “Protective Equipment against harmful noise”, with EU type-examination (annex V) and the procedures of annexes VII and VIII of Regulation (EU) 2016/425 (checked on 18 October 2026). How a CE marking with an identification number is read is explained by the Commission’s Blue Guide in section 4.5.1.5; more in CE marking and PPE category III.

All documents for the EarProtect products are collected under data sheets. If a document shows a different address from the legal notice, the guide New company address: is the certificate still valid? helps.

Other colours of the EP1227 series: EP1227BWG (blue/white/green), EP1227G (green), EP1227YO (yellow/orange), EP1227OWY (orange/white/yellow), EP1227OPW (orange/purple/white). All colours have the same test values; the overview with a comparison table is on the page Disposable foam earplugs. There are also earplugs with cord, in a case and the detectable version EP1227BD.
